Has the Information Content of Quarterly Earnings Announcements Declined in the Past Three Decades?

This paper examines changes in the information content of earnings over the past three decades using the two metrics from Beaver [1968]: abnormal trading volume and abnormal return volatility. We find no evidence of a decline in the information content of earnings announcements over the past three decades, as measured by both abnormal trading volume and return volatility around quarterly earnings announcements. If anything, our results suggest an increase over time in the informativeness of quarterly earnings announcements. Variables reflecting changes in firm-specific factors account for a portion of the observed increase.     

What drives the increased informativeness of earnings announcements over time?

Landsman and Maydew (J Acc Res 40:797–808, 2002) document that the information content of earnings announcements has increased over the past three decades, and Francis et al. (Acc Rev, 77:515–546, 2002) conclude that expanded concurrent disclosures in firms’ earnings announcements, especially the inclusion of detailed income statements, explain this increase. We posit and find that the temporal increase in the intensity of the market’s reaction to Street earnings offers a competing explanation for the Landsman and Maydew finding. We also find that expanded concurrent disclosure of GAAP-based information contributes to the temporal increase in the information content of earnings announcements. However, unlike Francis et al., we find that the temporal increase in concurrent balance sheet and cash flow statement information dominates concurrent income statement information once we control for Street earnings.

Do stock splits signal future profitability?

This study examines whether stock split announcements contain information content about future profitability, measured in terms of future earnings change, future earnings, or future abnormal earnings. We find that the split announcement year has the highest earnings change and the earnings change declines substantially over the subsequent five years. Our empirical results show little evidence that stock splits are positively related to future profitability. In fact, stock splits are in general negatively related to future profitability in subsequent years after the announcement, except for dividend-paying firms with a split factor less than 0.5. This negative relation holds regardless of future profitability measure. Therefore, our empirical finding suggests that stock splits are not useful signals of a firm’s future earnings prospects.

Options trading volume and stock price response to earnings announcements

We examine the effect of options trading volume on the stock price response to earnings announcements over the period 1996–2007. Contrary to previous studies, we find no significant difference in the immediate stock price response to earnings information announcements in samples split between firms with listed options and firms without listed options. However, within the sample of firms with listed options stratified by options volume, we find that higher options trading volume reduces the immediate stock price response to earnings announcements. This conforms with evidence that stock prices of high options trading volume firms have anticipated and pre-empted some earnings information in the pre-announcement period. We also find that higher abnormal options trading volume around earnings announcements hastens the stock price adjustment to earnings news and reduces post-earnings announcement drift.     

Informed trading before positive vs. negative earnings surprises

This paper investigates whether institutional investors trade profitably around the announcements of positive or negative earnings surprises. Using Korean data over the period of 2001–2010, we find that information asymmetry is larger before negative earnings surprises (earnings shock) among investors and that the trading volume decreases only before earnings shock announcements due to the severe information asymmetry. We also find that institutions sell their stocks prior to earnings shock announcements whereas individual and foreign investors do not anticipate bad news. Finally, we find that institutional trade imbalance is positively related to the post-announcement abnormal returns of negative events. This study complements and extends prior literature on informed trading around earnings announcements by documenting evidence that domestic institutions exploit their superior information around particularly earnings shock announcements.     

Individual Investor Trading and Return Patterns around Earnings Announcements

This paper provides evidence of informed trading by individual investors around earnings announcements using a unique data set of NYSE stocks. We show that intense aggregate individual investor buying (selling) predicts large positive (negative) abnormal returns on and after earnings announcement dates. We decompose abnormal returns following the event into information and liquidity provision components, and show that about half of the returns can be attributed to private information. We also find that individuals trade in both return‐contrarian and news‐contrarian manners after earnings announcements. The latter behavior has the potential to slow the adjustment of prices to earnings news.     

Are active fund managers collectors of private information or fast interpreters of public information?

Recent studies of fund manager performance find evidence of outperformance. However limited research exists as to whether such outperformance is because of privately collected information, or merely expedient interpretation of publicly released information. In this study, we examine the trade sequences of active Australian equity fund managers around earnings announcements to provide insights into the source of fund managers’ superior information. We document an increased occurrence of buy‐sell trade sequences around good‐news earnings announcements. The evidence is consistent with fund managers having both private information about forthcoming good‐news earnings announcements and being ‘short‐term profiteers’. We find no evidence that fund managers have private information about forthcoming bad‐news earnings announcements. However, we do find an increase in the frequency of fund managers not trading before bad‐news earnings announcements only to subsequently sell during announcements.     

Investor Information Demand: Evidence from Google Searches Around Earnings Announcements

The objective of this study is to investigate factors that influence investor information demand around earnings announcements and to provide insights into how variation in information demand impacts the capital market response to earnings. The Internet is one channel through which public information is disseminated to investors and we propose that one way that investors express their demand for public information is via Google searches. We find that abnormal Google search increases about two weeks prior to the earnings announcement, spikes markedly at the announcement, and continues at high levels for a period after the announcement. This finding suggests that information diffusion is not instantaneous with the release of the earnings information, but rather is spread over a period surrounding the announcement. We also find that information demand is positively associated with media attention and news, and is negatively associated with investor distraction. When investors search for more information in the days just prior to the announcement, preannouncement price and volume changes reflect more of the upcoming earnings news and there is less of a price and volume response when the news is announced. This result suggests that, when investors demand more information about a firm, the information content of the earnings announcement is partially preempted.     

The information content of stock splits

We develop a new methodology that controls for both the timing of annual earnings news (Asquith et al., 1989) and the performance prior to split announcements (Barber and Lyon, 1996) to evaluate the information content of stock splits. In contrast to existing evidence, we find that stock splits in aggregate are followed by positive abnormal future earnings growth, suggesting that stock splits contain information about future, rather than past, operating performance. When we use changes in breadth of institutional ownership as a new metric of information content to corroborate our findings, we find that splits with the greatest increase in breadth experience positive post-split abnormal returns and positive abnormal earnings growth. Together, our results suggest that some splits contain positive information about future performance, and that sophisticated market participants such as institutional investors are able to select these splits.     

How Much New Information Is There in Earnings?

We quantify the relative importance of earnings announcements in providing new information to the share market, using the R² in a regression of securities' calendar‐year returns on their four quarterly earnings‐announcement “window” returns. The R², which averages approximately 5% to 9%, measures the proportion of total information incorporated in share prices annually that is associated with earnings announcements. We conclude that the average quarterly announcement is associated with approximately 1% to 2% of total annual information, thus providing a modest but not overwhelming amount of incremental information to the market. The results are consistent with the view that the primary economic role of reported earnings is not to provide timely new information to the share market. By inference, that role lies elsewhere, for example, in settling debt and compensation contracts and in disciplining prior information, including more timely managerial disclosures of information originating in the firm's accounting system. The relative informativeness of earnings announcements is a concave function of size. Increased information during earnings‐announcement windows in recent years is due only in part to increased concurrent releases of management forecasts. There is no evidence of abnormal information arrival in the weeks surrounding earnings announcements. Substantial information is released in management forecasts and in analyst forecast revisions prior (but not subsequent) to earnings announcements.

Does the market overweight imprecise information? Evidence from customer earnings announcements

We examine how supplier-firm shareholders respond to the earnings announcements of their major customers to test the moderated confidence hypothesis, which predicts overreaction to imprecise signals. In our setting, the moderated confidence hypothesis predicts that supplier shareholders will overreact to customer earnings news because that news contains imprecise information about the suppliers’ future cash flows. We find evidence that supplier earnings announcement abnormal returns are negatively correlated with supplier abnormal returns at the earlier customers’ earnings announcements, consistent with supplier overreaction. We also find evidence that the overreaction declines with the strength of the economic ties between the supplier and the customer.     

Informed Trading in Corporate Bonds Prior to Earnings Announcements

This paper examines the information content of corporate bond trading prior to earnings announcements using data from both NAIC and TRACE. We find that the direction of pre‐announcement bond trading is closely related to earnings surprises. This link is most evident prior to negative news and in high‐yield bonds. Further, abnormal bond trading during the pre‐announcement period can help predict both earnings surprises and post‐announcement bond returns. Such predictive ability of bond trading largely originates from institutional‐sized trades and is concentrated in the issuer's most actively traded bond. Finally, even after accounting for transactions costs, informed bond trading can generate significant net profits, especially prior to the release of bad news.     

Increased market response to earnings announcements in the 21st century: An Empirical Investigation

We examine the role of concurrent information in the striking increase in investor response to earnings announcements from 2001 to 2016, as measured by return variability and volume following Beaver (1968). We find management guidance, analyst forecasts, and disaggregated financial statement line items are more frequently bundled with earnings announcements, and each of these items explains part of the increase in market response. Furthermore, collectively, these concurrent information releases explain a substantial fraction of the increase in market response to earnings announcements since 2001. This is in contrast to the decline in market response to management guidance issued separately from earnings and the much smaller increase in market response to analyst forecasts issued separately from earnings over this time. The findings indicate that information arrival at earnings announcement dates has increased significantly over the past two decades, and that key components of this are increased disclosures by management of guidance and financial statement line items and forecasts by analysts.     

The options market response to accounting earnings announcements

We examine the reaction of the equity options market to accounting earnings announcements over the period 1996–2008 using changes in implied volatility to measure the options market response to earnings news. We find that positive earnings surprises and positive profit announcements produce a larger uncertainty resolution than negative earnings surprises and loss announcements. We demonstrate an inverse relation between the change in implied volatility and earnings news in a three-day window immediately after an earnings announcement. We refer to the magnitude of this relation as the ‘options market earnings response coefficient’. This ‘options market earnings response coefficient’ is stronger for both bad news announcements and positive profit announcements. We do not find any significant relation between changes in implied volatility and earnings news in the pre- or post-announcement periods. We conclude that the options market efficiently absorbs earnings information.     

The Timeliness of Restatement Disclosures and Financial Reporting Credibility

This study investigates whether prompt discovery and disclosure of earnings restatements is associated with greater post‐restatement financial reporting credibility. We measure the timeliness of restatement detection by the length of time between the end of the misstated period and the subsequent restatement announcement. We document that shorter detection periods are significantly associated with high‐quality corporate governance characteristics and executive and/or auditor turnover, but not with characteristics of restatements. We also find that firms with shorter detection periods exhibit a more moderate decline in the information content of earnings following restatement announcements relative to firms with longer detection periods, and that detection period length has an incremental effect on the information content of earnings relative to executive and/or auditor turnover alone. In addition, we find that restatement disclosures are more timely following the implementation of the SOX‐era reforms, and that only firms with shorter detection periods experience more moderate post‐restatement declines in the information content of earnings following the implementation of the SOX‐era reforms. The results from this study suggest that the timeliness of restatement detection and disclosure is associated with greater financial reporting credibility following restatements.     

Public Predisclosure Information, Firm Size, Analyst Following, and Market Reactions to Earnings Announcements

Abstract:   This study examines the effects of public predisclosure information on market reactions to earnings announcements. We develop an empirical measure of public predisclosure information impounded in price prior to earnings announcements by cumulating abnormal returns on public news release dates during the quarter. Consistent with prior literature, we document a negative association between this measure and market reactions to subsequent earnings announcements. Moreover, we find that after controlling for this measure, firm size and analyst following are significantly positively associated with market reactions to earnings announcements. Contrary to prior empirical evidence, our results suggest that, after controlling for actual predisclosure information impounded in price, market reactions to earnings announcements are greater in magnitude for larger, more widely-followed firms than for smaller, less widely-followed firms.     

Too Good to be True? An Analysis of the Options Market's Reactions to Earnings Releases

Using option implied risk neutral return distributions before and after earnings announcements, we study the option market's reaction to extreme events over earnings announcements. While earnings announcements generally reduce short‐term uncertainty about the stock price, very good news does not reduce uncertainty and slightly bad news actually increases uncertainty. We also find that left tail probabilities decrease over earnings releases while right tail probabilities increase. We interpret these findings as evidence of maintained investor expectations that very good news is generally not released during earnings announcements, combined with skepticism in the form of lingering uncertainty at the release of such very good news.     

Information,uncertainty, and behavioral effects: Evidence from abnormal returns around real estate investment trust earnings announcements

In this study, we examine the influence of real estate market sentiment, market-level uncertainty, and REIT-level uncertainty on cumulative abnormal earnings announcement returns over the 1995–2009 time period. We first document the relative coverage of analysts' earnings forecasts on U.S. REITs, as well as REITs from several countries (i.e., Australia, Belgium, Canada, France, Hong Kong, Japan, the Netherlands, and UK). We show that coverage outside of the U.S. is limited, and we consequently focus our analysis on U.S. REITs. We find strong evidence that earnings announcements contain pricing relevant information, with positive (negative) earnings surprises relative to analysts' forecasts resulting in significantly positive (negative) abnormal returns around the announcement date. Consistent with the findings from the broader equity market literature, we find limited evidence of a pre-announcement drift in the cumulative abnormal returns. However, in sharp contrast to the existing equity literature, we find no evidence of a post-earnings announcement drift in our aggregate sample or when the sample is restricted to the largest negative surprises. We find evidence of a post-earnings announcement drift for only the largest positive earnings surprises. These results are consistent with REIT returns more quickly impounding information relative to the broader equity market, in part because of the parallel private real estate market and because of the U.S. REIT structure and information environment. Finally, in our conditional regression analysis of cumulative abnormal returns, we find that real estate investor sentiment, market-wide uncertainty, and firm-level uncertainty significantly affect the magnitude of abnormal announcement returns and also influence the effect of unexpected earnings on abnormal returns.
