Capital Markets Hypotheses and Samples description
949 proxy for differences in opinion amongst investors. In a similar vein, Bryan
and Tiras 2007 provide evidence that analyst forecasts are a proxy for other information and that higher level of dispersion indicates high information
asymmetry. Zhang 2006 also uses analyst forecast dispersion as a measure of information uncertainty. Gebhardt, Lee and Swaminathan 2001 on the
other hand, uses variance of analysts forecast as risk. These characterizations are not without problems and possible contradictions. For
example, Diether, Malloy and Scherbina 2002 show that higher analysts forecast variance generate a higher level of stock return, thus contradicting
the risk interpretation of the measure. Evidence consistent with the interpretation of informational uncertainty has been provided by many studies
such as Diether et al., 2002 and Han and Manry 2000 who document that firms with higher variance of analysts‘ earnings forecast have relatively lower
future stock returns and ROE. In another important paper, Easterwood and Nutt 1999 document that either extreme good news or extreme bad news is
associated with increased uncertainty about earnings. Consistent with Easterwood and Nutt 1999, Gu and Xue 2007 document that variances of
analysts forecasts are indeed higher for extreme good news and bad news, thus confirming the characterization of informational uncertainty. However, no
direct evidence of informational uncertainty has been documented so far. Theoretical models strive for rational explanations Trueman 1990;
Verrecchia 1983; Dye 1985 and empirical studies provide documentation Chambers and Penman 1984; Givoly and Palmon 1982; Kothari et al, 2007
that good news about corporate performance comes out earlier than the bad news. In the context of annual earnings, the implications of later arrival of bad
950 news could be that of higher informational uncertainty, increased private
information acquisition by individual investors and financial analysts, and increased variance in analysts‘ forecasts of earnings for bad news. In this
study, we investigate and offer evi dence that the variances of analysts‘
forecasts are systematically different in Good News and Bad News environment and how the extent of good and bad news may affect such
varinces
21
Following the measures developed by Barron et. al. 1998 we also offers evidence that such differential in variance can be explained by the
underlying information environment of public vs. private information of analysts. We also examine if the variance of analysts‘ forecasts differ
systematically during the fiscal year for good-news and bad-news environments and for the different amount of good or bad news. Finally we
also examine the economic significance of such differential variances in connection to earnings forecasts and future stock returns.
More specifically, this study examines the level and change in the variance of analysts‘ forecasts over the fiscal year under good-news and bad-
news environments preceding earnings announcement. It uses four definitions of good-news and bad-news events
– two ex ante definitions and two ex post
definitions. For each definition, the variance of analysts‘ forecasts of earnings is compared at various points of time prior to the annual earnings
announcement to answer the following four research questions: First, is the variance of an
alysts‘ earnings forecasts significantly different for forecasts associated with good and bad earnings news, and if so, how does it differ
21
Payne and Robb 2000 have used a reverse argument that lower variance of analyst forecast would be a motivating factor for managers to expend extra effort to meet market
expectations. Hence a ―good news‖ by way or meet or beat earnings forecast is more likely to follow a lower forecast variance.
951 across different levels of good and bad news? Second, does the differential
in variances can be explained by the amount of private v. public information with analysts? Third, does the variance of analysts‘ forecasts changes
differentially and predictably over the fiscal year in good-news and bad-news environments? Fourth, , does the variance of financial analysts‘ earnings
forecasts explain cross-sectional variation in the level of earnings based on expected news good-news or bad-news in earnings? Finally, do arbitrage
portfolios based on the analysts‘ forecast variance and the nature of expected underlying news generate positive abnormal stock returns? In this final test
we confirm the results of Diether, Malloy and Scherbina 2002 and refine their results to show that the interaction of the nature of news and the forecast
variance generate an even higher level of stock return. Our empirical findings are that after controlling for firm, year, and pre-
earnings announcement period quarter, the variance of analysts‘ earnings forecasts is smaller when there is good-news about earnings. We also confirm
the Gu and Xue 2007 results that variances of analysts forecast is greater when the underlying news is extreme. We show that after controlling for the
level of good news and bad news, analysts forecast variance is higher for the bad news variance. Further, using the measure developed by Barron et. al.
1998 we show that a the amount of private information of analysts are always higher in a bad-news environment and b the amount of private
information is higher when the news is extreme. Thus, higher variance is always associated with the higher private information of the analysts. In
addition, the variance in analysts‘ annual earnings forecasts decreases over time, in part, because of interim disclosure of mandatory information. The
952 evidence further suggests that the reduction in variance is earlier in the good-
news environment, consistent with the view that good news disclosures take place earlier and relatively less information is systematically produced for bad-
news announcements. Consistent with theory, we show that the private information of analysts also decreases over time. At an aggregate level,
reported earnings are negatively associated with the variance of the analysts‘ earnings forecasts, and firms with higher variance have lower earnings and
bad news. Thus, if a higher variance is caused by either the nature of the news good v. bad or the size of the news extreme v. small our result
indicate that on the average, the effect of the nature of the bad news, dominate that of the size of the good news. , As a result, the market
consensus forecast is smaller than the mean of analysts‘ earnings forecasts when analysts‘ forecasts variance is higher. We suggest the use of different
adjustment factors in different quarters for forecasts made in good and bad- news environments. Finally, our study documents that arbitrage portfolios
constructed at the end of each quarter on the basis of the variance of analysts‘ forecasts and the nature of the underlying news good-news or bad-
news generate year-end abnormal returns in the range of 6-10. The issue of information dissemination is important for capital market
researchers. The predictive power of the analysts‘ earnings forecast variance, if any, of the future earnings news at announcements is important for
investors and other market participants alike. If information in the variance of analysts‘ earnings forecasts improves the prediction of earnings, then the
market‘s expectation of earnings should assign a weight to this measure. To the extent the market fails to do so, it provides an opportunity to earn
953 abnormal returns around future earnings announcements and to develop
better earnings forecasts. The finding of this study, that the relative disclosure timing of good-news and bad-news Kothari et al., 2007 has differential
implication on the variance of analysts‘ forecasts, make several important contributions to the literature. No prior study has examined and documented
that both a the variance of analysts‘ earnings forecasts, and b the change
in t he variance of analysts‘ earnings forecasts over the fiscal year, vary
systematically for good and bad-news firms and explain the variation through the extent of private v. public information possessed by the analysts. The
finding that the variance of ana lysts‘ earnings forecasts contains information
that can be used to improve the prediction beyond the consensus analysts‘ forecast is also not present in the prior literature and has direct implications
for all capital market studies using consensus analyst forecast as market earnings expectation. Finally, though it has been documented that the
variance of analysts‘ earnings forecasts can be used to generate subsequent abnormal monthly returns Diether et al., 2002, our results indicate that these
abnormal returns are driven by firms with good and not bad-news. Furthermore, by forming portfolios at different points of time, this study
documents that the variance of analysts‘ forecast has information that can be used as early as the first quarter of the fiscal year to generate abnormal
returns based on expected earnings news. II. HYPOTHESES DEVELOPMENT
Information Arrival in Good-News and Bad-News Environments
Theoretical arguments support managerial incentives to delay the announcement of bad news. In a model that makes information manipulation
954 costly, Trueman 1990 shows that a strategic manager may delay releasing
bad news to receive additional information that could improve his or her ability to judge the costs and benefits of information manipulation. Furthermore, if
disclosure leads to proprietary costs, information gets released only if the benefits exceed the costs Dye 1985; Verrecchia 1983. Non-disclosure can
represent an extreme form of disclosure delay. Managers also have incentives to build their personal or corporate reputations to create a
―resolution preference‖ that encourages them to hasten the delivery of good news and postpone bad news Hirschleifer 1993. Finally, the manipulation of
information is time consuming and bad news is always manipulated to the greatest extent possible before its release, which may lead to the delay. A
simple explanation for this intentional delay posits that the passage of time is of value to a manager because interim actions and unforeseen events might
ameliorate the consequences of the bad-news event. Overwhelming empirical evidence provides corroborating evidence that
good news about corporate earnings comes out early, and bad news comes out later Chambers and Penman 1984; Givoly and Palmon 1982; Kross and
Schroeder 1984; McNichols 1988; Mendenhall and Nichols 1988; Patell and Wolfson 1982; Penman 1984; Begley and Fischer 1998; Kothari et al. 2007.
Kothari et al. 2007 consider this as a career concern of the manager because such disclosure strategy has the potential to alter management
compensation. They rightly observe that in cases of recent scandals managers explicitly withheld bad news from outside investors and such
955 behavior reinforces the belief that managers‘ private incentives significantly
influence the characteristics of corporate disclosures.
22
The literature points to other motives for timing disclosures. For instance, managers may delay the release of bad news to benefit from the
opportunity to exercise stock options. Several studies Baginski et al., 1994, Yermack, 1997, and Aboody, Barth and Kasznik, 2004 have shown that
managers accelerate bad news andor withhold good news in the period immediately preceding the option grant dates to lower the exercise price of
the options thus increasing the value of their option grants. Other studies Kasznik and Lev 1995, and Skinner 1994, 1997 show that managers
have a propensity to forewarn analysts of losses bad news to prevent increased exposure to litigation risk. This advance notice, however, refers
only to a warning prior to the statutory release of the information and does not suggest communication at the inception of the bad-news event or that it would
appear earlier if the firm had good news to report.
23
Other explanations for delay include audit complexities associated with bad news, delays by smaller
firms that have more bad news on average, and industry practices that cause more bad news during the test period. None of these explanations
receive strong empirical support over time e.g., Givoly and Palmon, 1982. To summarize, earlier as well as more recent studies Begley and Fischer,
1998, Kothari, 2007 provide evidence that after considering various
22
A more appropriate but extreme example of the value of the passage of time is the following story retold by Ro Verrecchia Verrecchia 1983. When sentenced to death by the
King, a knave offers to teach the King‘s horse how to talk in a year‘s time. He explains later to his friends, ―Within a year anything can happen, the King may die, the horse may die, or
the horse may even learn to talk.‖
23
It seems that under an experimental setting, analysts seem to believe that disclosures are downwards biased and managers have a definite pre-announcement strategy Tan et al.
2002.
956 incentives to manage news releases, managers release good news earlier
than bad news.
Analysts Incentive Interactions in Good News and Bad News Environments
Empirical evidence indicates that financial analyst incentives differ in analyzing firms with good news versus bad news. εcNichols and O‘Brien
1997 show that financial analysts are generally reluctant to be the first bearers of bad news and may choose to delay their information release. In
extreme cases of bad news, financial analysts may drop the firm rather than repeatedly release unfavorable news. Womack 1996 and Michaely and
Womack 1999 provide similar evidence when analysts face conflicts of interest arising from underwriting relationships. Because most analysts issue
buy-side recommendations, they do not want to antagonize their clients by possibly premat
urely ―crying wolf‖. Furthermore, firms experiencing poor performance may have an inherently higher level of uncertainty, whose
resolution takes longer, which would imply a later release of information. The notion that the nature of the news affects the communication,
interaction, and information flows among managers and analysts is well documented in empirical research. Burgstahler and Eames 2006 and
Matsumoto 1998 provide evidence that firms manage both earnings upwards and forecasts downwards in their effort to create good news by
meeting or beating analysts‘ expectations. They further argue that firms manage their forecasts by deliberately biasing their communications with
analysts to lower forecasts. Such forecast management can take many forms,
957 including but not limited to calls to analysts, and public ―pre-announcements‖
of bad news Kasznik and Lev, 1995, Skinner, 1994 1997, Bamber and Cheon, 1998 at least in qualitative terms. Firms releasing good news could
be more precise than for bad news. For example, a good-news release could refer to improvements in earnings per share, whereas a bad-news release
might offer only general terms Skinner 1994. Brown 2001 contends that managers‘ incentives to manage earnings and analysts differ dramatically
when they report losses versus profits. When reporting bad news, managers do not forewarn analysts. Degeorge et al. 1999 demonstrate the decreased
increased communication among firms and analysts when firms report losses profits, perhaps to reduce increase the frequency of bad news
good news.
24
Taken together, these characteristics suggest significant differences in good and bad news forecast environment, which can influence
the properties of analysts‘ forecasts.
Impact of Inf ormational Characteristics on the Variance of Analysts‟
Forecasts
Empirical studies document that financial analysts revise and update their forecasts in response to quarterly reports Abdel-khalik and Espejo,
1978, management forecasts Jennings, 1987, other analysts‘ forecasts
Stickel, 1990, and changes in stock prices Brown et al., 1985. Changes in the frequency and nature of interactions with managers can influence the
properties of analyst forecasts. Until recently, analysts routinely conducted informal discussions with managers on a regular basis. However, with the
24
Lev and Penman 1990 find that earnings forecasts, as a rule, differentiate firms with ―good‖ annual earnings from other firms and that, on average, forecast news is ―bad‖.
958 passage of SEC Regulation Fair Disclosure, this communication is not
possible anymore. Researchers have used the variance in analysts‘ forecasts to measure
earnings predictability and the degree of consensus in the market. Imhoff and Lobo 1992 show that the ex ante uncertainty of earnings predictability, as
captured by the variance in analysts forecasts, correlates with the earnings response coefficient. Daley et al. 1988 indicate that the variance in analysts
forecasts correlates with the magnitude of unexpected earnings and, by implication, the ex-post variance of realized earnings. They also show that the
variance in analysts forecasts captures the ex ante variance of stock prices, similar to Patell and Wolfson 1979. Ziebart 1990 uses the variance
measure as a surrogate for market belief consensus, which correlates positively with trading volume.
Several studies argue that variance of analysts‘ forecasts capture the nature of information environment that determines forecast accuracy. Brown,
Richardson and Schwager 1987 construct their measure of forecast accuracy of analysts by comparing the variances of tome series forecasts and analysts
forecasts. Other studies document that the accuracy of analyst forecasts is correlated with the variance coefficient of variationdispersion of the analysts
forecasts Elton, Gruber and Gultekin 1981,. Gu and Xue 2007 show that the variance of analysts forecasts is much larger when the news is either
extremely good or extremely bad. They show a U-shaped relationship between news and variance, but fail to identify that the U shape is asymmetric
with larger steepness on the left bad news than the right good news. A comparison of the relative magnitude of variance under good news and bad
959 news provides additional insights on the role of news on analysts‘ earnings
forecast variance that our study seeks to exploit.
Definitions of Good News and Bad News Environments
Degeorge et al. 1999 consider three earnings thresholds that induce income manipulation to generate good bad news: meet or beat not meet or
beat prior performance, report profits losses, and meet or beat not meet or beat analysts‘ expectations. Because our focus is on the properties of
analysts‘ forecasts, we could only use the first two measures. We contend that consensus mean forecasts the threshold for meeting and beating
expectation and variance of analysts‘ forecasts may not be independent. We define ex post good and bad news as follows:
A. A reported increase in earnings from last year is good news, and a reported decrease is bad news.
B. A reported profit is good-news, and a reported loss is bad news. We also consider ex ante definitions of good and bad news. Unlike the ex
post grouping, which is based on realized earnings, the ex ante grouping depends on whether the expected news about the firm is good or bad.
Following our earlier arguments and our definition of good-news and bad- news scenar
ios, we expect the variance of analysts‘ forecasts to be smaller in the case of good-news announcements over all, and also to be so after
controlling for the level of the good bad news.
H1:
The variance of analysts‘ forecasts of annual earnings is smaller in good-news environments.
Our interpretation of the variance in analysts forecasts, though consistent with the literature, also posits that good and bad news information
960 environments lead to two distinct distributions of analyst‘s forecasts
characterized by differential variances. We conclude that bad-news leads to a decrease in the amount of information available to analysts at the time of their
forecasts. Thus, the forecast generated by financial analysts in bad-news environments is conditional on relatively less information that is likely to be
noisier. The lack of news may also affect the degree of private information available to the analysts and the weights they assign to this information.
Following Barron et al. 1998 and Barron et al. 2002, such lack of precision and lack of consensus would lead to a higher variance in analysts‘ forecasts
of earnings in bad-news environments. Thus our second hypothesis follows:
H2:
A smaller larger variance of analysts‘ forecasts of annual earnings is associated with a large proportion of public private
information with the analysts.
If consensus building takes place over time, both good and bad-news firms should exhibit a steady reduction of forecast variance over time. This
could be partly due to the interim release of the mandatory quarterly earnings reports. Blackwell and Dubins 1962 show that opinions about an unknown
event tend to converge as the amount of available information increases. If good-news arrives faster than bad-news, the forecast variance under good
news should decrease faster over time than for bad news, at least in the early quarters. Kasznik and Lev 1995 point out that later fourth quarter of each
year has by far the largest number of analysts‘ forecasts which suggests an increased rate of information arrival. Therefore, information acquisition both
private and public is likely to be significantly more in later periods that are closer to the annual earnings announcement. We treat the fourth later
961 quarter information environment differently also because it coincides with the
release of annual earnings, which are audited and more closely scrutinized. Accordingly, our hypothesis is:
H3:
i The variance of analysts‘ forecasts of annual earnings declines over the year; ii the rate of variance reduction is
higher in earlier periods for firms with good-news.
To further exploit the role of analysts earnings forecast variance, we examine its ability to predict future earnings. Given Hypothesis 1, the analyst
earnings forecasts variance should convey information beyond the mean forecast information. Therefore, analysts earnings forecast variance should
play a role in predicting earnings. However, with the passage of time and because good news arrives early, the role of variance should diminish for
good-news announcements. For bad-news announcements, analysts earnings forecast variance may continue to play a role until such time when
the underlying uncertainty is resolved. Ceteris paribus, if higher variances are associated with bad news, then the effect of increased variance on earnings
forecasts should be more pronounced for firms with bad-news.
H4: For a given level of annual earnings forecast, i actual earnings are negatively associated with t
he variance of analysts‘ forecasts, and ii this association is more pronounced in the bad-news environment.
Finally, we investigate the possible economic impact of differential analysts earnings forecast variance under the two news environments on stock returns. Though Diether et al. 2002 have documented that portfolios
formed on the variance of analysts‘ forecasts can be used to earn positive abnormal returns, we further partition the variance levels by the nature of the expected news, and state Hypothesis 4 as follows:
H5: i For any news environment, the buy-and-hold stock returns will be higher for stocks with smaller forecast variance, and ii the largest
962 arbitrage return is between the good news-low variance and the bad
news-high variance portfolios.
