Introduction

Macroeconomic indicators are a class of periodically released numbers summarizing key properties of a country’s economy. Examples are the unemployment rate and inflation related measures such as the Consumer Price Index (CPI) and the Producer Price In-dex (PPI). These indicators are typically compiled by agencies as the Bureau of Labor Statistics (BLS), the Bureau of Economic Analysis (BEA), and the Federal Reserve Sys-tem’s Board of Governors (FRB) in the United States, Statistics Netherlands (CBS) in the Netherlands, or the Centre for European Economic Research (ZEW) in Germany.

Releases of macroeconomic indicators are widely believed to contain valuable infor-mation because investors use them to revise their beliefs and expectations about macroe-conomic conditions. The content of macroemacroe-conomic indicators is closely followed by professionals in the financial industry, as well as by the financial and popular press. As a result, daily comments in the press often explain price movements in financial markets by referring to macroeconomic indicators that deviated from the expectations of investors and financial analysts. As an example, consider the following excerpt from the New York Times from October 17, 2008.

(13)

“The economy may be sputtering, but the threat of stagflation - a concern among some economists just weeks ago - appears to have receded somewhat. [...] The Consumer Price Index, considered an important gauge of inflation, was unchanged last month [...]. Stock index futures jumped after the report, as investors bet that the more optimistic economic data would bring buyers back into the stock market.”

This excerpt illustrates one occasion when a release of the Consumer Price Index (CPI) was perceived to change investors’ beliefs and expectations, which was subsequently be-lieved to lead to a sharp price increase in stock index futures. In today’s financial markets, this is not a stand-alone event and macroeconomic news events are commonly associated with price movements.

The conventional wisdom that financial markets react to macroeconomic news is con-firmed by the academic literature. The literature shows ample evidence that macroeco-nomic news events influence returns and its volatility on stock, bond, and foreign ex-change markets. For example, Flannery and Protopapadakis [2002], Bomfim [2003],

Adams et al.[2004], and Bernanke and Kuttner[2005] show that announcements about

monetary policy and real activity affect the level and conditional volatility of stock re-turns. In addition, McQueen and Roley [1993] and Boyd et al. [2005] show that stock

markets respond differently to news contained in macroeconomic announcements, de-pending on whether the economy is expanding or contracting. The asymmetry in re-sponses over expansions and contractions is because macroeconomic events may contain news on both future interest rates and growth expectations, which are valued differently over the business cycle. For example,Boyd et al.[2005] show that for unemployment rate

announcements, news about interest rates dominates during expansions, while news about growth expectations dominates during contractions.Jones et al.[1998],Fleming and

Re-molona[1997,1999],Balduzzi et al.[1998,2001], andDe Goeij and Marquering[2006],

(14)

macroe-3

conomic fundamentals on employment, inflation, housing and output. Andersen et al.

[2003] show that foreign exchange markets respond to the announcements of

macroeco-nomic fundamentals as well. Finally,Wongswan[2006],Funke and Matsuda[2006] and

Andersen et al.[2007] document that the releases of U.S. macroeconomic fundamentals

affect prices, trading volume, and volatility in European and Asian markets.

As is also illustrated by the New York Times excerpt above, the responses of finan-cial markets to macroeconomic announcements can be economically large. AsSavor and

Wilson[2013a] remark, macroeconomic announcement days are important for financial

markets since a substantial part of annual returns in financial markets seems to be earned on announcement days. For example,Jones et al.[1998] find a bond return Sharpe ratio

of 0.145% on days on which the Bureau of Labor Statistics’ (BLS) employment report and PPI are announced, compared to a Sharpe ratio on other days of a mere 0.01%. For stocks, Savor and Wilson [2013b] document that on FOMC rate announcement days,

and BLS’ employment report and inflation announcement days, Sharpe ratios are signif-icantly higher than on other days. Recently,Lucca and Moench [2013] show that stock

market returns in the 24-hour period prior to FOMC rate announcements are orders of magnitude larger than average returns outside of this 24-hour pre-FOMC window. For the period March 1994 to September 2011, 80% of the cumulative equity premium was earned during this pre-FOMC window. In a discussion of Lucca and Moench [2013],

Annette Vissing-Jorgensen shows that the high pre-FOMC announcement earnings are particularly high when important macroeconomic news was scheduled in the pre-FOMC window.

announcements. Following the literature, we define macroeconomic announcement news as the difference between the median of analysts’ prior forecasts and the actual release of the fundamental. Including news on a set of widely followed individual macroeconomic announcements in the cross-section of stock returns, we find price of risk estimates for sensitivity to good news on the economy that are generally positive during expansions, but generally negative during contractions. The signs of the estimated prices of risk are in line with good news on the economy being bad news for stock markets during expansions, while during contractions, good news on the economy is good news for stocks as well. However, given that for most fundamentals, prices of risk are not statistically significant different from zero, we conclude that the available macroeconomic announcement data are too short for precise estimation of its factor prices.

In Chapter 3, we empirically study the relation between uncertainty about macroeco-nomic announcements and the expected returns of stocks. Following Anderson et al.

[2009], amongst others, we measure uncertainty in beliefs about macroeconomic

an-nouncements with the disagreement in analysts’ forecasts. For a large set of macroeco-nomic fundamentals that are generally believed to be important movers of financial mar-kets, we test whether innovations in uncertainty about macroeconomic announcements helps to determine expected returns on stocks. Our results show that factor price esti-mates for uncertainty about macroeconomic fundamentals are often economically large and of opposite sign over expansions and contractions. Furthermore, factor prices can be statistically significant and stocks’ loadings to announcement uncertainty can be very precisely estimated. However, when we look at the premium induced by sensitivity to an-nouncement uncertainty across portfolios, implied confidence intervals for induced pre-miums are often sizable. The large implied confidence intervals for induced prepre-miums make it difficult to draw conclusions about the economic relevance of the contribution of announcement uncertainty to expected returns.

about macroeconomic fundamentals and return volatility. When analysts are forming their beliefs prior to the announcement, does higher return volatility result in higher uncer-tainty in beliefs amongst analysts? And, does higher unceruncer-tainty in beliefs increase return volatility on financial markets? To proxy for uncertainty in beliefs about macroeconomic fundamentals, we use a daily updated measure of dispersion in analysts forecasts for the unemployment rate and the PPI, allowing us to analyze causality between announcement uncertainty and return volatility using both daily and monthly frequency. Using either daily or monthly data, we demonstrate that there are no causal effects from stock and bond return volatility to macroeconomic announcement uncertainty, as estimates are precisely estimated around zero. Considering causality the other way around, we find evidence for no causality from macroeconomic announcement uncertainty to return volatility using daily data. However, analyses using monthly data show that announcement uncertainty is positively causally related to stock and bond volatility. The discrepancy in results from analyses using daily and monthly data suggests that, on daily frequency, announcement uncertainty might be correlated with a hidden factor that is causally related with stock and bond return volatility. When this is the case, correlation between announcement un-certainty and return volatility on daily frequency will indicate causality when monthly frequency data is used in causal analyses.

Is macroeconomic announcement news

priced?

This chapter is based onde Goeij et al.[2013a].

2.1

Introduction

In financial markets, macroeconomic announcements are frequently surrounded by large price movements. Jumps in return and trading dynamics around the release of macroeco-nomic fundamentals suggest that these announcements contain news that is relevant for investors and should therefore drive prices and expected returns. Theory provides a strong case for seeing macroeconomic news as risk, for which investors command a reward in addition to the reward for the traditional risk factors.Ross[1976]’s arbitrage pricing

the-ory predicts that variables that relate to common variation in financial assets are priced risk factors.Campbell and Hentschel[1992] argue that the arrival of small (large) pieces

of news lowers (increases) expected future volatility, resulting in higher (lower) prices to-day. In the model ofBansal and Yaron[2004], the recursive nature of agents’ preferences

leads to price reactions and equity risk premiums when news on expected growth rates arrives.

(19)

Existing studies show that macroeconomic announcement news events move prices on financial markets. Fleming and Remolona [1999], Balduzzi et al. [2001], Andersen

et al. [2003, 2007] and Faust et al. [2007], for example, show that bond and foreign

exchange prices respond to news contained in announcements on employment, inflation, output, housing, and consumer and producer confidence. For stocks, earlier studies find little evidence that their prices respond to macroeconomic announcements other than to inflation (see, for example,Schwert[1981],Hardouvelis[1987] andCutler et al.[1989]).

However, recognizing that news contained in macroeconomic announcements may affect expected cash flows and discount rates differently during expansions and contractions,

McQueen and Roley [1993], Boyd et al. [2005] and Andersen et al. [2007] show that

stocks respond negatively to news about higher economic activity and employment during expansions, but positively during contractions.

Despite the evidence that macroeconomic announcement news moves prices, rela-tively few studies deal with how exposure to macroeconomic announcement news is re-warded. Jones et al. [1998] argue that the substantial increases in bond return volatility

typical to macroeconomic announcement days are caused by the arrival of macroeco-nomic news. They find a bond return Sharpe ratio of 0.145% for days on which the Bu-reau of Labor Statistics’ (BLS) employment report and PPI are announced, compared to a mere 0.01% for other days. Boyd et al.[2005] investigate the effects of unemployment

news on stocks and find that positive unemployment shocks are positively related to their proxy for the equity risk premium. Finally,Savor and Wilson[2013b] document that for

days when FOMC rate decisions are announced, or for announcement days for the BLS employment report and inflation statistics, Sharpe ratios are significantly higher than for other days. However, their reported announcement day Sharpe ratios are largely driven by the high returns observed just prior to FOMC announcements, as is documented by

Lucca and Moench[2013].1 AsSavor and Wilson[2013a] also remark, macroeconomic

2.1. Introduction 9

announcement days are important since a substantial part of annual returns in financial markets seems to be earned on announcement days.

A natural question that follows is whether the high average announcement day returns are compensation for sensitivity to news contained in macroeconomic announcements. In this paper, we address this question and investigate whether sensitivity to macroeco-nomic announcement news is a priced risk that partly determines expected returns. To examine whether macroeconomic news events constitute priced risks, we relate news contained in macroeconomic announcements to the cross-section of announcement day returns. Considering the evidence from the literature that investors may value the same news differently over the course of the business cycle, we allow for different factor prices for macroeconomic news during expansions and contractions.

Our cross-sectional results show the following. For 12 out of the 14 considered macroeconomic fundamentals, we find that sensitivity to good news on the economy commands a positive price of risk during expansions, but a negative price of risk dur-ing contractions. These estimates are in line with the results of McQueen and Roley

[1993] andBoyd et al.[2005], who find that good news on the economy is bad news for

(21)

of its prices of risk. To obtain longer series on macroeconomic news events, we pool individual macroeconomic fundamentals with similar content. However, estimates for the factor prices for the macroeconomic news groups are not statistically different from zero for any of the categories of news events considered.

Given that we have considered the longest available series of macroeconomic sur-vey data and used various specifications, we conclude that the available data is too short for precise inference of its factor premia using conventional efficient estimators. Our results are useful for future research, and indicate that other methods (for example, us-ing econometric models instead of analysts surveys to measure the market’s expectations of macroeconomic announcements), might be more fruitful for precise estimation of the factor premia associated with macroeconomic announcement news.

The remainder of the paper is structured as follows. Section 2 outlines the empirical framework we use. In Section 3, we describe the data on macroeconomic surveys and announcements. To built intuition, Section 4 first describes the large differences in aver-age returns between announcement days. Next, we report the cross-sectional results from augmenting the Fama-French model with macroeconomic announcement news. Finally, Section 5 concludes.

2.2

Research design

To test whether news contained in macroeconomic announcements changes the risk-return relation for stocks, we relate macroeconomic announcement news to expected returns in a linear factor model. We specify the cross-sectional risk-return relation for asset i as

E(Rei,t) = c + βi,FT λF+ J

j=1

βi,MEAjλMEAj, (2.2.1)

(22)

2.2. Research design 11

fundamental of type j. λF and λMEAj are its corresponding prices of risk.

AsMcQueen and Roley[1993] andBoyd et al. [2005] argue, stock markets respond

differently to news contained in macroeconomic announcements, depending on whether the economy is expanding or contracting. This asymmetry is because macroeconomic events may contain news on future interest rates and growth expectations, which are val-ued differently over the course of the business cycle. In particular,McQueen and Roley

[1993] and Boyd et al. [2005] find that news about interest rates dominates during

ex-pansions, while news about growth expectations dominates during contractions. Thus, when the economy is strong, good news on economic activity is bad news for stocks as it signals an increase in interest rates, while during contractions, good news about eco-nomic activity signals improved growth expectations. To allow for a different relation between macroeconomic announcement news and expected returns over expansions and contractions, we generalize (2.2.1) as follows

E(Rei,t) = c + βi,FT λF+ J

j=1 βi,MEAE jλMEAE j+ J

j=1 βi,MEAC jλMEAC j, (2.2.2)

where βi,MEAE j is stock i’s loading to MEAj× DE and βi,MEAC j its loading to MEAj× DC. Here, DE and DC are dummy variables that take the value 1 during expansions and contractions, respectively. λMEAE

j is the price of risk for macroeconomic news of type j during expansions, while λMEAC

j is the price of risk for macroeconomic news of type j during contractions.

Equations (2.2.1) and (2.2.2) link the expected returns on stocks to the risk factors in

F, and to news on macroeconomic fundamentals j = 1, ..., J. While we cannot observe all news events that investors use to update their beliefs about macroeconomic fundamental j, we will focus our empirical analysis solely on scheduled announcement days, days for which we know for sure that news about fundamental j arrives.2 Thus, for each

macroeconomic fundamental j, we estimate the following cross-sectional equation

E(Rei,tj) = c + βi,F,TT jλF,Tj+ β

E i,MEAj,Tjλ E MEAj,Tj+ β C i,MEAj,Tλ C MEAj,Tj, (2.2.3)

where tj ∈ Tj is the set of announcement days for macroeconomic fundamental j. βi,F, jT are asset i’s loadings to the risk factors in F, estimated on the set of announcement days Tj, with λF,Tj its prices of risk. β

i,MEAj,,T are asset i’s loadings to announce-ment news of type j during expansions and contractions, respectively, estimated on the set of announcement days Tj. λMEAE j,Tjand λMEAC j,Tj are their corresponding prices of risk. The traditional risk factors included in the empirical tests are the market, size, and value factors, for which summary statistics for the traditional risk factors are given in Table 1. Return data on the value-weighted market index andFama and French[1992]’s

size and value factors are obtained from the website of Professor Kenneth French for the period January 1, 1980 to December 31, 2011. The value-weighted market index is in excess of the one-month Treasury bill rate from Ibbotson Associates. The empirical tests are performed using the framework ofHansen[1982]’s Generalized Method of Moments

(GMM), for which the details are summarized in the Appendix. FollowingLewellen et al.

[2010], we include the excess return market index and the size and value factors in our set

of assets, thus implicitly imposing λF = ET(Ft).

(24)

2.3. Macroeconomic survey and announcement data 13

2.3

Macroeconomic survey and announcement data

We obtain survey and announcement data on a set of widely followed macroeconomic fun-damentals from Money Market Services (MMS) International and Bloomberg. MMS In-ternational has been conducting its survey on macroeconomic announcements from 1980 until the end of 2004, when it was discontinued after the company was taken over by In-forma Financial Group. Forecast data from the MMS survey have been widely used in the literature on macroeconomic announcements (e.g.Andersen et al.[2003,2007],De Goeij

and Marquering[2006] andFunke and Matsuda[2006]). Bloomberg has been conducting

surveys on scheduled macroeconomic releases since February 1997. Initially, the survey covered releases of the Bureau of Economic Analysis’ (BEA) Gross Domestic Product (GDP) but within two years of its inception, it was extended to include other widely fol-lowed macroeconomic releases such as BLS’ Consumer Price Index (CPI), Producer Price Index (PPI) and unemployment rate, and the FRB’s Industrial Production. Currently, the Bloomberg survey covers more than 40 regularly scheduled macroeconomic releases. We merge the two surveys using the MMS survey for the period January 2, 1980 to October 31, 2004 and the Bloomberg survey for the period November 1, 2004 to December 31, 2011.3

We follow the literature (Pearce and Roley [1985], Balduzzi et al.[2001], Flannery

and Protopapadakis[2002], and many others) and proxy macroeconomic news as the

dif-ference between the actual announcement, Ajt, and the median in analysts’ prior forecasts, fjt. To allow for comparison of estimates across fundamentals with different units of mea-surement, all surprises are demeaned and standardized. Thus, news about fundamental j is defined MEAjt = Ajt− fjt ˆ σj , (2.3.1)

where ˆσj is the sample standard deviation of the difference between the announcements

3Tests for the equality of means for the MMS and Bloomberg surveys from January 4, 1999 to October

(25)

and forecasts for macroeconomic fundamental of type j.

Table2.2describes the macroeconomic news series that are included in our analysis.

The table lists the sources of the macroeconomic fundamentals, its starting date, its unit of measurement, and some summary statistics prior to demeaning and standardizing.

2.4

Empirical results

This section presents our main empirical results. Section2.4.1carries out some

prelim-inary analyses and shows that average returns are distinctly different on announcement days, depending on whether the announcement contained good news or bad news and depending on whether the economy is expanding or contracting. Section2.4.2deals with

the main question of this paper and examines whether news on a set of widely followed macroeconomic fundamentals is priced. In Section2.4.3, we construct groups of

macroe-conomic fundamentals with similar emacroe-conomic content, pooled together to obtain longer macroeconomic news series. Section2.4.3.2reports estimates and their precisions for the

cross-sectional prices of risk for the macroeconomic news groups.

2.4.1

Announcement day returns

To obtain some intuition on macroeconomic announcement news events and expected returns, Panel B of Table2.3compares average daily excess returns for the market index

across the announcement days of the fundamentals included in the dataset. Columns 3-5 describe announcement day returns, also distinguishing between days with positive and negative announcement shocks.4 To examine the difference in average returns over expansions and contractions, Columns 6-8 describe average announcement day returns during expansions, and Columns 9-11 describe average announcement day returns during

4We refer to positive differences between the announced value and analysts’ prior forecast as positive

(26)

2.4. Empirical results 15

contractions. For comparison, Panel A of the Table summarizes daily returns for the market index for all days from January 1, 1980 to December 31, 2011

The table reports the averages and standard deviations of returns. For convenience, we annualize all average daily returns by multiplying it with 250 while standard devia-tions are annualized by multiplying it with the square root of 250. We do this regardless of whether the returns were averaged over the full sample or only over the subset of an-nouncement days. Note though, that annualizing anan-nouncement day returns and standard deviations in this way may give the impression that during the year, each day was an an-nouncement day, which is of course not the case. The p-values reported in Panel A are for the test that expected daily return over the full sample from January 1, 1980 to December 31, 2011 is zero. The p-values reported in Panel B, on the other hand, are for the test that announcement day expected returns equal expected daily return over the full sample from January 1, 1980 to December 31, 2011.

The table shows that announcement day average returns can be quite substantial. For example, annualized average daily returns on the Institute of Supply Management’s (ISM) index announcement days and the Census Bureau’s New home sales announcement days are an economically impressive 45% and 34%, respectively. This is much higher than the annualized daily market return of about 7% over the full sample.

(27)

6-8 and Columns 9-11 describe average announcement day returns in expansions and contractions, respectively. The columns show that average returns are in line with the finding in literature that good news on the state of the economy is bad news for stocks during expansions, while during contractions, good news on the economy is good news for stocks. For example, when the economy is expanding, negative Nonfarm Payrolls employment shocks, positive unemployment rate shocks, or a negative shock in the ISM index are characterized by high daily average returns of between about 48% − 110% per annum. In contractions, for days with bad news on Nonfarm payrolls (negative shocks), the unemployment news (positive shocks), or the ISM index (negative shocks), annualized average daily returns are between about −21% and −12%.

While the differences in average announcement day returns across expansions and contractions, and between days with positive and negative shocks are impressive, we cannot yet conclude from these results that returns on announcement days are driven by macroeconomic announcement news. To formally examine whether macroeconomic news events constitute priced risk, we test whether macroeconomic news help explain the cross-section of returns. This we do in the next section.

The portfolios are constructed as follows. We download all common NYSE, AMEX, and NASDAQ stocks from the Center for Research in Security Prices (CRSP). Individual stock returns are in excess of the one-month Treasury bill rate from Ibbotson Associates and the sample period is January 1, 1980 to December 31, 2011. For each non-penny stock5 with at least 20 or more announcement day observations during both expansions and during contractions, we estimate (2.2.3) on the set of announcement days Tj. In our

first attempt, stocks are sorted into portfolios on the basis of their sensitivity to macroe-conomic announcement news. Since we know from the literature that stocks respond differently to macroeconomic announcement news over the course of the business cycle, we allocate stocks to portfolios on the basis of βMEAE j,Tj during expansions, while during contractions, we allocate stocks portfolios on the basis of βMEAC

j,Tj. To define expansions and contractions, we use the the Chicago Fed National Activity Index (CFNAI) index. Each portfolio has the same cumulative market cap, is rebalanced on a daily basis, and value-weighted. However, when sorted only on sensitivity to MEAj, the portfolios with the lowest and highest βMEAj,Tjcontain a very large number of small stocks, while middle portfolios contain relatively few, larger stocks. Though post-formation loadings to MEAj line up as expected for the portfolios sorted on βMEAj,Tj, average portfolio returns seem to reflect a size premium: the portfolios with the lowest and highest βMEAj,Tj contain a large number of small stocks and have higher average portfolio returns, while the middle portfolios contain relatively few, large, stocks and have lower average returns than the outer portfolios.

To correct for a possible dependence between loadings to announcement news MEAj and size, we construct portfolios sorted on both size and sensitivity to macroeconomic announcement news. First, we sort stocks into three size portfolios, where the cumula-tive market cap of each size-portfolio equals one-third of the total NYSE, AMEX, and NASDAQ market cap. Then, the stocks in each size portfolio are sorted into four

portfo-5We define penny stocks as stocks with prices lower than 5. Thus, when a stock’s price drops below 5

(29)

lios on the basis of their βi,MEAE

j,Tj during expansions, and on the basis of their β

C i,MEAj,Tj during contractions. Again, cumulative market cap is the same across all portfolios, and portfolios are rebalanced on a daily basis and are value-weighted.

As an illustration, Table2.4reports various statistics for the 3 × 4 portfolios formed on

size and sensitivity to Nonfarm payrolls employment (NFP) news. The left blocks of Pan-els A and B report the portfolios’ post-formation βMEAE

NFP,TNFP and β

C

MEANFP,TNFP, while the right blocks of Panels A and B report the t-statistics for the test that the portfolios’ post-formation loadings are zero. Panels A and B of Table2.4show that the portfolios’

post-formation loadings to NFP announcement news line up as expected. That is, within each size group, sensitivity to news on NFP increases from about −0.20 for portfolio 1 to about 0.20 for portfolio 4. Also, the loadings of the lower and higher βMEANFP,TNFP portfolios are all significantly different from zero.

Remember that portfolios were constructed on the basis of stocks’ βMEAE

j,Tj during ex-pansions, while during contractions, stocks are allocated to portfolios on the basis of their βMEAC

j,Tj. To compare portfolio average returns, we thus also consider portfolio returns during expansions and contractions separately. Panels C and D of Table2.4 report

aver-age announcement day portfolio returns during expansions and contractions, respectively. For each panel, the left block reports average announcement day return, while the right block reports the t-statistics for the test that the portfolio expected return equals zero. In Panel C, the average return for the difference between portfolios 5 and 1 is positive for all size groups, suggesting a positive price of risk for NFP news during expansions. Panel D, on the other hand, shows a negative average portfolio return for the difference portfolio, suggesting a negative price of risk for NFP during contractions. These average returns are in line withMcQueen and Roley [1993] and Boyd et al. [2005], who argue

this). Even though we cannot draw any conclusions from these average portfolio returns, they suggest that NFP news commands a positive price of risk during expansions, and a negative price of risk during contractions.

2.4.2.2 Is macroeconomic announcement news priced?

To examine whether macroeconomic announcement news is a priced risk for stocks, we now examine the relation between macroeconomic announcement news in the cross-section of returns. For each macroeconomic fundamental j, (2.2.3) is estimated on the

set of announcement days Tj for fundamental j using the 25 Fama-French portfolios and the value-weighted 3 × 4 portfolios sorted on size and sensitivity to announcement news. Table2.6reports the estimates for the prices of risk in (2.2.3) for all macroeconomic

fun-damentals in our dataset. For comparison, Table2.5gives the cross-sectional results for

the Fama-French model estimated on all daily returns for our full sample period from January 1, 1980 to December 31, 2011.6 Remember that to allow for comparison across fundamentals with different units of measurement, we standardized all macroeconomic news series. This implies that the prices of risk estimated for the macroeconomic news series equal their Sharpe ratios. Coefficients and adj. R2are estimated using GLS, while standard errors account for the errors-in-variables problem inherent to cross-sectional re-gressions.

Table2.6shows factor price estimates for good news on the economy which are

neg-ative during expansions, but positive during contractions. This is the case for all consid-ered macroeconomic fundamentals, except for the ISM index and the Census Bureau’s consumer confidence index. The asymmetric price estimates for macroeconomic

nouncement news are in line with the existing literature which shows that, during ex-pansions, good news on the economy is bad news for stocks, but that during contractions, good news about the economy is also good news for stock markets (McQueen and Roley

[1993], Boyd et al.[2005] andAndersen et al.[2007]). Boyd et al.[2005], for example,

also show that their proxy for the equity risk premium responds positively to bad news on the unemployment rate during expansions, while its response during contractions is not significantly different from zero. For PPI and CPI, prices of risk are negative during expansions but positive during contractions. This is in line with the negative response of stock markets to higher inflation during expansions documented byMcQueen and Roley

[1993] andAndersen et al.[2007]. Thus, for almost all macroeconomic news series,

esti-mates for its prices of risk are of the expected signs during expansions and contractions. However, only few of those estimates are statistically different from zero, suggesting that individual macroeconomic news series are too short for precise estimation of its prices of risk. In the next subs-section, we try and improve on this precision by grouping macroe-conomic indicators by emacroe-conomic content to obtain longer series.

The prices of risk that are statistically significant in Table2.6are the U. Mich.’s

two examples suggest, the contribution of announcement news to expected returns can be economically substantial, and can differ across macroeconomic fundamentals.

In Table2.6, the cross-sectional adj. R2’s are reported in the second-to-last columns.

For comparison, for each macroeconomic fundamental, we also report the cross-sectional adj. R2 of the regression on the Fama-French factors only, estimated on the same set of announcement days Tj. As the table shows, when we augment the Fama-French model with macroeconomic announcement news, the adj. R2slightly increases. For example, on the announcement days of the U. Mich. Consumer Confidence index, adding news on the announcement to the Fama-French factors increases cross-sectional adj. R2 with about 4%. However, increases in adj. R2are generally relatively small and the adj. R2’s are thus likely not outside of each others’ confidence interval.

In a recent paper,Savor and Wilson[2013a] show that on the announcement days for

the BLS’ employment report, BLS’ CPI or PPI, and the announcement days for FRB’s FOMC interest rate decisions, there is a much stronger relation between the traditional risk factors and average returns. In contrast to their results, we do not find stronger evi-dence for the CAPM or Fama-French model on announcement days, but rather the other way around (which we suspect to be due to the reduction in sample size). This is because the strong risk-return relation documented by Savor and Wilson [2013a] is particularly

strong on FOMC announcement days. When FOMC announcement days are excluded fromSavor and Wilson [2013a]’s set of announcement days, the relation between

aver-age returns and market beta becomes much weaker. As is shown byLucca and Moench

[2013], average returns earned during the 24 hours prior to the 2.15 p.m. FOMC rate

Macroeconomic news groups

2.4.3.1 Construction of the macroeconomic news groups

The previous section showed that, given the available data, prices of risk for individ-ual macroeconomic news events are not precisely estimated. A natural question to ask is whether longer series will improve efficiency in estimation of the prices of risk for macroeconomic news events. To obtain longer series on macroeconomic announcement news, we pool the macroeconomic fundamentals to construct factors that contain news on similar economic content. The constructed groups comprise the categories employ-ment, inflation, forward-looking fundamentals, consumer confidence, output and housing, where each category contains the macroeconomic fundamentals that are listed under its group heading in Table2.2.

To make sure that the groups load positively on employment, inflation, output, etc., we multiply the individual news series in each group with 1 or −1.7 For example, the employment news factor loads positively on positive shocks to Nonfarm payrolls employ-ment but loads negatively on higher than expected Unemployemploy-ment rate or the Departemploy-ment of Labor’s (DOL) Initial jobless claims. Since all macroeconomic fundamentals con-sidered in this paper, except for the Unemployment rate and Initial jobless claims, load positively on employment, inflation, output, etc., we multiply Unemployment rate news and Initial jobless claims news with −1 when constructing the groups, while all other news group constituents are multiplied with 1. Prior to pooling, individual announcement news series are standardized to unit standard deviation, and demeaned. Finally, the indi-vidual series in each group are stacked together, with news that is announced on the same day, averaged.

2.4.3.2 Prices of risk for the macroeconomic news groups

Table 2.7 reports the estimates for the prices of risk in (2.2.3), where we substitute the

macroeconomic news factors ^MEAj for news on individual macroeconomic fundamen-tals, MEAj. The assets used are the 25 Fama-French portfolios and the 3 × 4 portfolios sorted on size and βE

^ MEAj,Tj

during expansions, and on size and βC ^ MEAj,Tj

during contrac-tions. As before, macroeconomic news is standardized such that their estimated prices of risk equal their Sharpe ratios. Factor price estimates and cross-sectional adj. R2’s are calculated using GLS, and the reported GMM standard errors automatically correct for the errors-in-variables problem due to the two-pass nature of cross-sectional regressions.

Our intention for creating the macroeconomic news factors ^MEAjwas to obtain longer series with similar macroeconomic news content to estimate prices of risk for macroeco-nomic news events more efficiently. Table2.7shows that pooling macroeconomic

funda-mentals does not lead to estimates of its prices of risk so precise that they are statistically significant. Furthermore, for half of the groups, the sign of the price of risk estimates are different from what is expected from economic reasoning. For example, factor price estimates for good news on employment, forward-looking fundamentals and consumer confidence are negative during expansions. However, as shown byBoyd et al.[2005] and

others, good news on the state of the economy is bad news for stocks and thus, a negative price of risk is economically not plausible.

Chapter 3

Uncertainty about macroeconomic

announcements and the cross-section of

returns

This chapter is based onde Goeij et al.[2013b].

3.1

Introduction

InMerton[1973]’s framework, the returns on financial assets are determined by the

con-ditional covariances of asset returns with innovations in state variables describing future investment opportunities. In this setting, it is assumed that investors can accurately as-sess probabilities over future investment outcomes. More recently, a large number of studies (among others, Hansen and Sargent[2001], Maenhout[2004], Hansen and

Sar-gent[2010],Ui [2011], andJu and Miao [2012]) show theoretically that when investors

are averse to unknown payoffs as well as uncertainty about the distribution of payoffs, expected return is driven by two components; one related to the traditional risk factors and one related to investors’ uncertainty in beliefs. Empirically, Anderson et al. [2009]

(47)

on stocks, whileYu [2011] shows empirically that innovations in aggregate uncertainty

correlates positively with the returns on the market portfolio.

Macroeconomic news events are arguably the most important news events for finan-cial markets.Pearce and Roley[1985],Jones et al.[1998],Fleming and Remolona[1999],

Balduzzi et al.[2001],Andersen et al.[2003,2007], andBoyd et al.[2005], amongst

oth-ers, show that macroeconomic news events commonly move stock, bond, and foreign exchange markets. The evidence that financial markets are sensitive to macroeconomic news events suggests that releases of macroeconomic indicators contain valuable informa-tion that investors use to revise beliefs and expectainforma-tions about actual and future macroe-conomic conditions. While the literature shows that aggregate uncertainty is important for the pricing of financial assets, little is known about how uncertainty in beliefs about macroeconomic news events affect returns. In a recent paper,Beber and Brandt [2009]

show that the reduction in uncertainty implicit in stock and bond options after macroe-conomic announcements is bigger when ex-ante uncertainty about the announcement is higher. This result suggest that uncertainty about macroeconomic announcements has repercussions for pricing in financial markets as well.

In this paper, we empirically study the relation between uncertainty about macroe-conomic announcements and the expected returns of stocks. FollowingAnderson et al.

[2005, 2009], amongst others, we measure uncertainty in beliefs about macroeconomic

(48)

3.2. Data and preliminaries 37

This is puzzling, since from economic reasoning one would expect investors to always be averse to uncertainty, resulting in negative factor prices for announcement uncertainty in both expansions and contractions. Even though post-formation loadings and factor prices for announcement uncertainty are often precisely estimated, confidence intervals for premiums induced by announcement uncertainty are generally quite sizable. Thus, even though induced premiums can be statistically different from zero, the large confi-dence range makes it difficult to determine the economic contribution of announcement uncertainty to expected stock returns.

The remainder of the paper is structured as follows. Section 3.2 describes the data

and the construction of our proxy for uncertainty about macroeconomic announcements. In Section 3.3, we specify the specifications that will be used in the empirical

investi-gations. In Section3.4, we first examine whether uncertainty about announcements is a

priced factor for stocks. Second, we explore the premium that is induced by sensitivity to announcement uncertainty across stocks. Section3.5presents some robustness checks.

Finally, Section3.6concludes.

Survey forecasts on macroeconomic announcements

(49)

are then published the same day, accompanied by the name of the analyst, the institution he or she is affiliated with and the date of publication of the forecast. Prior to the releases of the macroeconomic fundamentals, analysts are allowed to revise their forecasts on the terminal.

We obtain analysts’ individual forecasts for a set of widely followed macroeconomic fundamentals for the period January 1, 1998 to December 31, 2011. The start of our sam-ple coincides with the inclusion of several influential macroeconomic fundamentals such as the PPI and the unemployment rate in the Bloomberg survey. Table3.1describes the

macroeconomic fundamentals included in our analysis. The table reports the source of the fundamentals, the date it was included in the Bloomberg survey on macroeconomic announcements, and the average number of contributors to the surveys for the full sample and for the years 1998 and 2011. The large number of analysts and financial institu-tions who contribute to the survey (many of them over a longer period) shows that the Bloomberg survey on macroeconomic announcements is widely used by financial profes-sionals. For the period from January 1, 1998 to December 31, 2011, the average number of analysts that, each period, contribute to the Bloomberg survey ranges from 34.5 for announcements of the Department of Labor’s (DOL) Initial Jobless Claims, to 66.6 for BLS’ unemployment rate announcements. The table also shows that the average number of contributing forecasters has steadily increased over time. For example, the number of contributors to the survey on unemployment rate announcements increased from an average of 39.5 for each release in 1998 to an average of 82.2 for each release in 2011.

3.2.2

Construction of the macroeconomic uncertainty measure

To proxy for the uncertainty in beliefs about an outcome, many existing studies use the disagreement in analysts’ point forecasts. Examples areJohnson[2004],Anderson et al.

[2005, 2009], Barron et al.[2009], andBeber et al.[2010], who proxy aggregate

(50)

3.2. Data and preliminaries 39

In this paper, we follow this literature and proxy uncertainty about macroeconomic an-nouncements with the disagreement in analysts’ point forecasts from the Bloomberg sur-vey on macroeconomic announcements.1 Note though that, strictly speaking, disagree-ment in forecasts does not necessarily measure uncertainty since forecasts do not detail how sure or unsure analysts are about their beliefs. But, asBeber et al. [2010] remark,

uncertainty is a pre-condition for disagreement but much more difficult to measure. Fur-thermore, the existing literature shows evidence that disagreement and uncertainty are correlated, supporting the use of disagreement as a proxy for uncertainty. For example, comparing disagreement between analysts’ point and density forecasts from the Survey of Professional Forecasters (SPF),Lambros and Zarnowitz[1987] find that disagreement

in point forecasts is positively correlated with measures of diffuseness across analysts’ probability histograms.2 Similarly, Giordani and Söderlind[2003] find a positive

corre-lation between these two measures but show that disagreement tends to be lower than uncertainty measured using density forecasts. Finally, Bomberger and Frazer Jr [1981]

andBomberger[1996] find a positive correlation between disagreement and uncertainty

measured as the conditional variance of forecast errors.

Alternatively, uncertainty about the state of the economy can also be proxied with the implied volatility from derivatives traded on macroeconomic events, or from analysts’ subjective probability forecasts as published by the SPF.3Since probability forecasts from the SPF are available only on a quarterly basis, and macroeconomic derivatives were only

1In this paper, we refer to our measure as a proxy for uncertainty. As noted byGuidolin and Rinaldi

[2013], in the literature, the terms ambiguity and uncertainty are often used equivalently to refer to events in which agents are unsure of the correct probabilities underlying the outcomes.

2The SPF survey, currently administered by the Federal Reserve Bank of Philadelphia, publishes

ana-lysts’ subjective probability histograms along with their point forecasts. The survey has been publishing economists’ point and density forecasts on a quarterly level for output growth and inflation since 1968, when it was initiated by the American Statistical Association (ASA) and the National Bureau of Economic Research (NBER) as the ASA-NBER survey.

3Beber and Brandt[2006,2009] proxy uncertainty about Nonfarm payrolls announcements with the

(51)

available for a relatively short period of time, uncertainty measures constructed using SPF forecasters or macroeconomic derivatives are most likely too low frequency with too few observations for precise estimation of factor prices in the cross-section of returns, which is the goal of this paper.

A caveat in using individual forecasts to calculate uncertainty in beliefs is bias aris-ing from the career concerns of analysts. Lamont [2002] andClement and Tse [2005],

among others, show that reputation and competition motivate forecasters to give more bold forecasts, which are generally less accurate. To reduce the effect of bold and biased forecasts, we follow Anderson et al. [2009] and pre-multiply individual forecasts with

weights such that we underweight extreme forecasts and give relatively higher weights to forecasts around the consensus. The weights imposed on the forecasts follow a sym-metric beta distribution and are calculated as follows. At any given date t, all outstanding forecasts are ranked from low to high. Next, the weight on the ith lowest forecast is given by wit(v) = i v−1(N t+ 1 − i)v−1 ∑Nj=1t jv−1(Nt+ 1 − j)v−1 , (3.2.1)

where Nt is the number of outstanding forecasts available at time t and the shape pa-rameters of the beta distribution are equal to v. In contrast to Anderson et al. [2009],

in this paper we do not estimate v but set it equal to 15.4 Finally, uncertainty about the macroeconomic announcement is calculated as the mean absolute deviation of forecasts

ut= Nt

i=1 wit fit+τ|t− Nt

j=1 wjtfit+τ|t , (3.2.2)

where fit+τ|t, i = 1, ..., Ntare the outstanding forecasts at date t for the release at date t + τ. utmeasures uncertainty in forecasts using only beliefs about the announcement scheduled for t + τ that are available on date t or before. This is possible since the date on which

4Anderson et al. [2009] find that their results are largely invariant to other choices for v or to using

(52)

3.2. Data and preliminaries 41

each individual forecast is published is given in the Bloomberg survey.

Even though most forecasts are given in the week prior to announcement days, some forecasts are published relatively long before the release date.5 To illustrate this, Figure

3.8.3 presents the average number and percentage of published forecasts on the

unem-ployment rate and the PPI, published in the two weeks prior to the announcement. As the figure shows, about 80% of total unemployment rate forecasts and about 40% of to-tal PPI forecasts are published in the 5 days prior to the announcement day. Though we cannot tell what the underlying reasons are for analysts to issue early forecasts (nor is it in the scope of the paper to analyze this), it is very well possible that career concerns may play a stronger role in early forecasts than in later forecasts. As explained above, it is important to adjust for bold forecasts when constructing an uncertainty measure us-ing individual forecasts. However, with only few forecasts, weighus-ing forecasts usus-ing the weights from (3.2.1) does not reduce the effects of bold forecasts, and spikes in the values

for ujare often observed on days with few forecasts. To control for this, we exclude days for which less than 15 forecasts are available when calculating our proxy for macroeco-nomic announcement uncertainty, uj.6 We make one further adjustment when calculating uj. In the first year after the introduction of the macroeconomic announcement survey on the Bloomberg terminal, some forecasts on the unemployment rate were backdated by Bloomberg. We exclude all backdated individual forecasts from our analysis.

Since forecasts are expressed in different units of measurement across different funda-mentals, ut is centered and normalized to allow for comparison across fundamentals with different units of measurement. Thus, for each j = 1, ..., J, uj gives uncertainty about the announcements of fundamental j, where uncertainty is rescaled to deviations from its mean, and with unit standard deviation and zero mean. Given that disagreement in

ana-5A week prior the announcement day, Bloomberg sends an e-mail to forecasters, inviting them to publish

their forecast on the survey. It is possible though for analysts to submit forecasts prior to the date the e-mail is send out.

6As a robustness, Section3.5.2gives the results when we consider days for which not 15, but instead 10

(53)

lysts forecasts is highly serially correlated over consecutive days, we use daily innovations in the uncertainty proxy in our empirical tests, which are denoted as ∆ujfor fundamental j, j = 1, ..., J. As an illustration, Figures 3.8.1 and 3.8.2 show this rescaled proxy for

announcement uncertainty for the unemployment rate and the PPI. The shaded periods in the figures are identified as contractions by the Chicago Fed National Activity Index (CFNAI). In the figures, the top plot shows the rescaled proxy for uncertainty about the unemployment rate and the PPI, respectively, while the bottom plot graphs its daily first differences. Table 3.2 reports correlations for innovations in our proxy for uncertainty

about the unemployment rate and the PPI, respectively, and the market, size and value factors. The table shows that correlations of ∆uU nempand ∆uPPI are relatively small, and except for the correlation between ∆uU nemp and HML, they are not statistically different from zero.

If investors are averse to uncertainty about macroeconomic announcements, stocks with different loadings to innovations in macroeconomic announcement uncertainty will dif-fer in their expected returns. To test whether macroeconomic announcement uncertainty commands a reward, we therefore relate the cross-section of expected returns to common risks, and innovations in uncertainty about macroeconomic announcements. We use the following linear specification

E(rit) = c + βiFTλF+ J

j=1

j=1 βi∆uj∆ujt+ εit, (3.3.2)

where αiis an asset-specific constant.

Korajczyk and Levy[2003] andLevy and Hennessy[2007], amongst others, show that

the commonly observed countercylicality in firms’ leverage ratios can be explained by fi-nancial constraints changing over the business cycle. If fifi-nancial constraints and leverage ratios are different over expansions and contractions, this may also result in differences in firms’ sensitivity to economic uncertainty over expansions and contractions. Therefore, we extend specification (3.3.1) to allow for the possibility that firms’ exposure to

uncer-tainty about macroeconomic fundamentals changes over the business cycle. Furthermore, asMcQueen and Roley[1993] and Boyd et al.[2005] show, stock markets respond

dif-ferently to news contained in macroeconomic announcements, depending on whether the economy is expanding or contracting. They argue that the asymmetry in responses over expansions and contractions is because macroeconomic events may contain news on both future interest rates and growth expectations, and news about interest rates dominates dur-ing expansions while news about growth expectations dominates durdur-ing contractions. If this is the case, then uncertainty about the same economic news event may signal uncer-tainty about interest rates or growth expectations, depending on whether the economy is expanding or contracting and this may be valued differently by investors. To allow for the possibility that firms’ exposure to uncertainty, or investors’ appetite for uncertainty are different during expansions or contractions, we extend (3.3.1) as follows

E(rit) = c + βiFTλF+ J

j=1 βi∆uE jλ∆uE j+ J

j=1 βi∆uC jλ∆uC j, (3.3.3) where βi∆uE j and β C

As noted in Section 3.2, the vast majority of analysts publish their forecasts about

macroeconomic fundamentals only in the week before the announcement. As a result, ∆ujis generally only observed in this pre-announcement week. Since we cannot observe innovations in announcement uncertainty on other days, we limit our empirical investiga-tion to the set of days for which announcement uncertainty is observed. Thus, for each macroeconomic fundamental j, we estimate the relation in (3.3.1) and (3.3.3) only on

days for which we observe ∆uj

E(ritj) = c + βiF,TT jλF,Tj+ βi∆uj,Tjλ∆uj,Tj, (3.3.4)

E(ritj) = c + β T iF,TjλFTj+ β E i∆uj,Tjλ E ∆uj,Tj+ β C i∆uj,Tjλ C ∆uj,Tj, (3.3.5)

where tj∈ Tjis the set of days for which ∆ujt, our proxy for announcement uncertainty for fundamental j, is observed. βi,F,Tj are asset i’s loadings to the risk factors in F, estimated on the set of announcement days Tj, with λF,Tj its prices of risk. β

The traditional risk factors included in the empirical tests are the market, size, and value factors. Return data on the value-weighted market index and Fama and French

[1992]’s size and value factors are obtained from Professor Kenneth French’s website for

the period January 1, 1998 to December 31, 2011. The value-weighted return index is in excess of the one-month Treasury bill rate from Ibbotson Associates. Summary statistics for the traditional risk factors are given in Table3.3.

The empirical tests are performed using the framework ofHansen[1982]’s

General-ized Method of Moments (GMM), for which the details are summarGeneral-ized in the Appendix. FollowingLewellen et al.[2010], we include the excess return market index and the size
