Are corporate managers savvy about their stock price? Evidence from insider trading after earnings announcements

We find that insiders trade as if they exploit market underreaction to earnings news, buying (selling) after good (bad) earnings announcements when the price reaction to the announcement is low (high). We also find that insider trades attributable to public information about earnings and the price reaction generate abnormal returns. By demonstrating that managers spot market underreaction to earnings news, our results imply that managers are savvy about their company’s stock price.     

Investor and (Value Line) Analyst Underreaction to Information about Future Earnings: The Corrective Role of Non-Earnings-Surprise Information

Prior research suggests that financial analysts' earnings forecasts and stock prices underreact to earnings news. This paper provides evidence that analysts and investors correct this underreaction in response to the next earnings announcement and to other (non-earnings-surprise) information available between earnings announcements. Our evidence also suggests that analysts and investors underreact to information reflected in analysts' earnings forecast revisions and that non-earnings-surprise information helps correct this underreaction as well. Controlling for corrective non-earnings-surprise information significantly increases estimates of the degree to which analysts' forecasting behavior can explain drifts in returns following both earnings announcements and analysts' earnings forecast revisions.     

Post-split underreaction: The importance of prior split history

The magnitude of the underreaction following a stock split is different depending on the number of splits that have already occurred. The first three splits are followed by abnormal profitability and significant underreaction, which are outcomes consistent with managers using splits to signal favorable information about the firm's prospects. However, abnormal profitability fails to materialize and the underreaction gradually dissipates with each subsequent split suggesting the efficacy of a split announcement as a vehicle to convey information is not constant but steadily reduces with each successive split. The underreaction is distinct from any short-term announcement effects and indicates the market does not immediately impound the split's information content. There is no significant change in liquidity around each consecutive split confirming that the underreaction is not explained by microstructure effects. As is the case with other corporate events, the market interprets the content of announcements already made multiple times differently from announcements made less often.     

Investor and Analyst Reactions to Earnings Announcements of Related Firms: An Empirical Analysis

In this article I examine the response of investors and analysts of nonannouncing firms to the earnings report of the first announcers in the industry. The error in the earnings forecast of the first announcer is found to be informative about the errors in the contemporaneous earnings forecasts of subsequent announcers in the industry. However, investors and analysts do not appear to fully incorporate the information from the first announcers' news in their revised earnings expectations for subsequent announcers. This apparent underreaction to the first announcers' news leads to predictable stock returns for subsequent announcers in the days following the first announcement. Results of this study can be seen as further evidence of investor and analyst underreaction to publicly available information.     

The timing of information arrival and overnight returns

This paper examines the information assimilation of overnight returns after positive or negative news arriving during RHT (regular-hours-trading) or AHT (after-hour-trading). We first show that overnight returns are informative of earnings news arriving either during RHT or AHT, and the effects are strongest on the first day after the announcement. Our results then suggest that positive (negative) overnight returns after good (bad) earnings news arrival increase (decrease) CARs, with more pronounced effects for news released AHT. We further show that the market takes the timing of news release into account and reacts negatively to those released during AHT, causing significant under-performance in the subsequent CAR. Lastly, our finding of market underreaction to good news and overreaction to bad news when it is released during AHT suggest that it may be more appropriate for managers to release all news during RHT when market participants are at their trading desks.     

Underreaction to Industry‐Wide Earnings and the Post‐Forecast Revision Drift

We test whether the post‐forecast revision drift is mainly attributable to investors’ underreaction to industry‐wide earnings news conveyed by analysts’ forecast revisions. We find a large drift associated with industry‐wide earnings news but no drift associated with firm‐specific earnings news. Consistent with the functional fixation hypothesis, we provide evidence that the post‐forecast revision drift is driven by investors’ underreaction to the higher persistence of industry‐wide earnings. Although prior research has focused on differential persistence of earnings components stemming from managerial reporting discretion, we provide evidence suggesting that investors do not fully understand the differential earnings persistence attributable to industry fundamentals.     

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.     

The Stock Market's Reaction to Unemployment News: Why Bad News Is Usually Good for Stocks

We find that on average, an announcement of rising unemployment is good news for stocks during economic expansions and bad news during economic contractions. Unemployment news bundles three types of primitive information relevant for valuing stocks: information about future interest rates, the equity risk premium, and corporate earnings and dividends. The nature of the information bundle, and hence the relative importance of the three effects, changes over time depending on the state of the economy. For stocks as a group, information about interest rates dominates during expansions and information about future corporate dividends dominates during contractions.     

Surprise vs anticipated information announcements: Are prices affected differently? An investigation in the context of stock splits

We compare the long run reaction to anticipated and surprise information announcements using stock splits. Although there is underreaction in both cases, anticipated splits are treated differently to those that are unforeseen. After anticipated splits, cumulative abnormal returns peak at one-and-a-half times the level observed after unanticipated splits although the time taken for the announcement to be absorbed into prices is the same. We explain the difference in underreaction by the degree to which split announcements are believed and hence invested in. The favorable signal conveyed in forecast splits is more credible owing to their better pre-split performance, resulting in a far more pronounced underreaction effect.     

Corporate goodness and profit warnings

Is a firm that is known for positively engaging stakeholders expected to voluntarily disclose bad financial news? If it makes the announcement, does its corporate goodness help to mitigate the stock price reaction? We examine these issues using a sample of profit warnings, and a sample of firms with negative earnings surprises that did not warn. Firms that have positive corporate social responsibility ratings are more likely to provide earnings warnings than other firms. When they do provide a profit warning, the event negative abnormal returns are of significantly smaller magnitude than the returns of other firms providing warnings. This effect does not occur for social firms that decide not to warn. They suffer the same negative stock price impact on the earnings announcement day as other firms.     

Earnings Announcement Lags and Market Responses—Does the Tone of the News and the Market Sentiment Matter?

We investigate earnings announcement lags (period from the end of the reporting period until the announcement date) for the good and the bad quarterly earnings news across different market sentiment periods as well as market reactions thereto. Companies listed on Baltic stock exchanges exhibit clear signs of strategic timing of earnings announcements. Earnings announcement lags for the bad news tend to be longer than those for the good news. This difference is more pronounced during low market sentiment periods. If the release of the bad news is postponed, abnormal return responses remain lower, as expected.     

Earnings Preannouncement Strategies

We examine the disclosure strategies managers follow when theyd preannounce quarterly earnings shortly before formal earnings announcements. We document that managers with bad news release essentially all of their news at the preannouncement date, while managers with good news only release about half of their news. Controlling for the combined news released at the preannouncement and earnings announcement dates, firms with negative earnings announcement surprises have significantly lower excess returns for the period from just before the preannouncement to just after the earnings announcement. This finding is consistent with the observed disclosure strategies whereby managers attempt to avoid negative earnings announcement surprises, and suggests that how information is presented can affect the market's reaction to that information.     

Aggregate Market Reaction to Earnings Announcements

This analysis identifies a distinct immediate announcement period negative relation between earnings announcement surprises and aggregate market returns. Such a relation implies that market participants use earnings information in forming expectations about expected aggregate discount rates and, specifically, that good earnings news is associated with a positive shock to required returns. Consistent with this interpretation we find that Treasury bond rates and implied future inflation expectations respond directly to earnings news. We also find some evidence that the negative relation between earnings news and market return persists beyond the immediate announcement period, suggesting that market participants do not immediately fully impound these future market return implications of aggregate earnings news.     

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.     

Asymmetric Trading Costs Prior to Earnings Announcements: Implications for Price Discovery and Returns

We show that the cost of trading on negative news, relative to positive news, increases before earnings announcements. Our evidence suggests that this asymmetry is due to financial intermediaries reducing their exposure to announcement risks by providing liquidity asymmetrically. This asymmetry creates a predictable upward bias in prices that increases preannouncement, and subsequently reverses, confounding short‐window announcement returns as measures of earnings news and risk premia. These findings provide an alternative explanation for asymmetric return reactions to firms' earnings news, and help explain puzzling prior evidence that announcement risk premia precede the actual announcements. Our study informs methods for research centering on earnings announcements and offers a possible explanation for patterns in returns around anticipated periods of heightened inventory risks, including alternative firm‐level, industry‐level, and macroeconomic information events.     

Effects of Preannouncements on Analyst and Stock Price Reactions to Earnings News

This study examines the effects of earnings preannouncements on financial analyst and stock price reactions to earnings news. Prior experimental research documents that when the signs of a preannouncement surprise and subsequent earnings announcement surprise are consistent (i.e., both either positive or negative), analysts make larger magnitude revisions to their future period earnings forecasts in response to the total earnings news conveyed in the preannouncement and earnings announcement than when the surprise signs are inconsistent. This study extends this research by examining a sample of actual preannouncements from 1993–1997 to determine whether the effects documented in laboratory settings manifest at the aggregate market level in stock prices and consensus analyst forecast revisions. Results indicate that after controlling for the sign of earnings news, sign of earnings, and sign of the earnings announcement surprise, stock prices and analyst forecast revisions respond more strongly when a preannouncement and subsequent earnings announcement elicit the same surprise signs than when the surprise signs are inconsistent. Further analysis indicates that the consistency of the signs of a preannouncement surprise and earnings announcement surprise is not associated with future earnings, suggesting that the magnified reaction of investors and analysts to consistent surprise signs is not a rational reaction to associations observed in market settings.     

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.     

Voluntary disclosure and the cost of equity capital: Evidence from management earnings forecasts

This paper examines the directional effects of management earnings forecasts on the cost of equity capital. We find that forecasters of bad news experience a significant increase in the cost of equity capital in the month after their disclosure. Conversely, the cost of equity capital for good news forecasters does not change significantly in the same period. We also indicate that the magnitude of changes in the cost of capital for good news forecasters is significantly lower than that for bad news forecasters and non-forecasters, which suggests that investors may view good news forecasts less credible. Finally, we show that the effect of the subsequent earnings announcement on the cost of equity capital is preempted by the management forecasts for bad news firms, and that the combined effects of the management earnings forecasts and the earnings announcement are not significant for both good news and bad news forecasters. Our paper contributes to the literature by adding evidence on directional effects of voluntary disclosures and on long-term economic consequences of management earnings forecasts.     

Lazy Prices

Using the complete history of regular quarterly and annual filings by U.S. corporations, we show that changes to the language and construction of financial reports have strong implications for firms’ future returns and operations. A portfolio that shorts “changers” and buys “nonchangers” earns up to 188 basis points per month in alpha (over 22% per year) in the future. Moreover, changes to 10-Ks predict future earnings, profitability, future news announcements, and even future firm-level bankruptcies. Unlike typical underreaction patterns, we find no announcement effect, suggesting that investors are inattentive to these simple changes across the universe of public firms.     

Asymmetric response to earnings news across different sentiment states: The role of cognitive dissonance

Using the Chinese stock market data, we test the hypothesis that cognitive dissonance influences the stock market response to earnings news. Supporting this notion, we find that investors disregard earnings news that contradicts their sentiment due to cognitive dissonance, thereby causing a muted announcement date price reaction to such news. Further analysis shows that higher retail concentration and greater valuation uncertainty of the underlying firm exacerbate this cognitive dissonance and hence amplify its impact, but less credible financial report does not. Finally, we find that cognitive dissonance is temporary for bad news under optimism, but is quite persistent for good news under pessimism. Overall, our findings offer a behavioral bias explanation to understand why investors underuse accounting information.
