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.     

Target abnormal returns associated with acquisition announcements: Payment,acquisition form,and managerial resistance

Abnormal returns earned by target firms at the time of initial acquisition announcements are related to form of payment, degree of resistance, and type of offer. Results indicate that interdependence among these characteristics is important. Previous research suggests that tender-offer targets earn higher abnormal returns than merger targets. After controlling for payment method and degree of resistance, however, the difference in abnormal returns between tender offers and mergers is insignificant. Resisted offers are associated with insignificantly higher returns than unresisted offers. Abnormal returns associated with cash offers are significantly higher than those associated with stock offers.     

Predicting abnormal returns from news using text classification

We show how text from news articles can be used to predict intraday price movements of financial assets using support vector machines. Multiple kernel learning is used to combine equity returns with text as predictive features to increase classification performance and we develop an analytic center cutting plane method to solve the kernel learning problem efficiently. We observe that while the direction of returns is not predictable using either text or returns, their size is, with text features producing significantly better performance than historical returns alone.     

Bidders’ strategic timing of acquisition announcements and the effects of payment method on target returns and competing bids

Using a sample of acquisition announcements released during trading versus nontrading hours, this study examines how the strategic timing of acquisition announcements determines the impact of the method of payment on target stock returns and competition among bidders. For overnight acquisition announcements, we find that cash payment offers positively and significantly affect acquisition premiums and target returns, yet these results do not hold for daytime announcements. Cash payment offers made during nontrading hours are more likely to deter potential bidders and complete proposed transactions. However, we find no such relationship for daytime announcements. These findings suggest that the timing of acquisition announcements by bidders is important for assessing the effects of payment method as a signal of target valuation and a preemption of competing bids.     

Predictable events and excess returns: The case of dividend announcements

This paper hypothesizes that the risk per unit of time and the required rate of return are higher than normal during an event period whose timing can be predicted. Consistent with this hypothesis this paper presents empirical evidence indicating that the unconditional mean rate of return, the variance of stock returns and their systematic risk are higher than ‘usual’ during dividend announcement periods. However, the documented increases in the systematic risk are not large enough to fully explain the ‘excess returns’. This finding is puzzling and hard to reconcile with existing theory.     

Macroeconomic announcements and asymmetric volatility in bond returns

This study analyses the impact of macroeconomic news announcements on the conditional volatility of bond returns. Using daily returns on the 1, 3, 5 and 10 year US Treasury bonds, we find that announcement shocks have a strong impact on the dynamics of bond market volatility. Our results provide empirical evidence that the bond market incorporates the implications of macroeconomic announcement news faster than other information. Moreover, after distinguishing between types of macroeconomic announcements, releases of the employment situation and producer price index are especially influential at the intermediate and long end of the yield curve, while monetary policy seem to affect short-term bond volatility.     

Bankruptcy spillover effects on strategic alliance partners

This paper examines whether a party to a strategic alliance or joint venture suffers from spillover effects when the other partner files for bankruptcy. We find that the non-bankrupt strategic alliance partners, on average, experience a negative stock price reaction around their partner firm's bankruptcy filing announcement. This negative effect is strongest for longer partnerships and those with higher returns at the announcement of the initial alliance formation. Furthermore, horizontal alliance firms in declining industries have lower returns, indicating that industry conditions can exacerbate expected problems for the non-bankrupt firm. Non-bankrupt partners also experience drops in profit margins and investment levels in the subsequent two years with the worst performance concentrated among the longer-term agreements. There is very little impact on the returns or performance for joint venture partners, which suggests that these agreements are more insulating for the partner firm.     

Dividend yields and stock returns: Implications of abnormal January returns

This study examines the empirical relation between stock returns and (long-run) dividend yields. The findings show that much of the phenomenon is due to a nonlinear relation between dividend yields and returns in January. Regression coefficients on dividend yields, which some models predict should be non-zero due to differential taxation of dividends and capital gains, exhibit a significant January seasonal, even when controlling for size. This finding is significant since there are no provisions in the after-tax asset pricing models that predict the tax differential is more important in January than in other months.     

Disagreement and the informativeness of stock returns: The case of acquisition announcements

We examine whether disagreement between managers and investors, in the context of mergers and acquisitions, affects the information contained in bidder returns. We test the disagreement hypothesis, which posits that disagreement causes investors to be less certain about their revaluation of acquiring firms, making bidder returns less informative. Consistent with this hypothesis, we find an inverse relation between bidder returns, which proxy for the degree of disagreement, and the change in the bidders' implied volatility. Also consistent with the hypothesis, we find that the significant inverse relation between bidder returns and the change in implied volatility holds only for cases of negative bidder returns. We test for alternative explanations of this relation, but continue to find robust support for the disagreement hypothesis. Finally, the relation between bidder returns and the likelihood of deal completion is stronger when announcement returns are more informative, suggesting managers “listen to the market” more when the market response is more informative.     

The Feller diffusion,filter rules and abnormal stock returns

We determine the conditional expected logarithmic (i.e. continuously compounded) return on a stock whose price evolves in terms of the Feller diffusion and then use it to demonstrate how one must know the exact probability density that describes a stock’s return before one can determine the correct way to calculate the abnormal returns that accrue on the stock. We show in particular that misspecification of the stochastic process which generates a stock’s price will lead to systematic biases in the abnormal returns calculated on the stock. We examine the implications this has for the proper conduct of empirical work and for the evaluation of stock and portfolio performance.     

Outside directors' equity incentives and strategic alliance decisions

This study examines whether the proportion of equity-based compensation in outside director compensation is associated with corporate strategic alliances. We hypothesize that equity incentives provided to outside directors mitigate potential agency conflicts between outside directors and shareholders that arise from the strategic alliance decision-making process, thus resulting in more alliance activities. Our empirical evidence indicates that the percentage of equity in outside director compensation is positively associated with the incidence and the number of strategic alliance activities. Additionally, when the proportion of outside directors' equity in total compensation is higher, firms with strategic alliances generate better future stock returns. Overall, our findings suggest that providing equity incentives in outside director compensation mitigates the agency problems inherent in corporate strategic alliance decisions and enhances the quality of alliance activities.     

The power of bad: The negativity bias in Australian consumer sentiment announcements on stock returns

This paper examines the equity market reaction to the monthly release of Australian consumer sentiment news. Our results indicate that consumer sentiment has valuable information content. Further, we document a version of the “negativity effect” (from the psychology literature) in which, upon announcement of bad (good) sentiment news, the equity market experiences a significant negative (no) announcement day effect. Notably, we find that the market recovers from the bad news shock relatively quickly post-announcement. The results are robust to a broad range of additional tests.     

The effects of legal regime on the patterns of stock returns surrounding ADR earnings announcements

This study examines the effects of legal regime on the patterns of stock returns surrounding the earnings announcements of American Depositary Receipt (ADR) programs. My results indicate that the properties of accounting earnings associated with the local legal regime of an ADR program spill over to U.S. GAAP reconciled earnings. In particular, I find that the market reacts significantly to the earnings announcements of the ADR programs from common law countries whose accounting earnings are known to be more conservative and timely, but not to those of the ADR programs from code law countries where the earnings are known to be less conservative and timely.     

Past managerial guidance and returns to variance trading around earnings announcements

I investigate the relationship between past managerial guidance and realized variance risk premiums (VRPs) – i.e., the difference between implied and realized variance – in equity options around earnings announcements. I find that implied variances are lower before earnings announcements but VRPs are higher when firms provide guidance. I also find higher option-implied jump risk when firms issue surprising guidance. Further tests suggest a portion of the higher VRPs are due to changes in perceived higher-order risks, but traders also underreact to the precision of information in short-term guidance. These results are attenuated for firms with a better information environment.     

Earnings announcements,private information,and strategic informed trading

In this paper, we estimate and test a multi-period model of strategic informed trading developed by Foster and Viswanathan [Foster, F.-D., Viswanathan, S., 1996. Strategic trading when agents forecast the forecasts of others, J. Finance 51, 1437–1478]. We employ the GMM using intertemporal patterns of price, trading volume and market depth, leading up to the earnings announcements made by NYSE firms. We find that multiple informed traders with heterogeneous private signals trade prior to the announcements. In addition, by comparing the results from daily and intra-day estimations, we find that the number of informed traders increases while the intensity of liquidity trading decreases, and that the adverse selection problem becomes more pronounced as the announcements approach.     

Cross-sectional association between abnormal returns and firm specific variables

Abnormal returns (market model prediction errors) are the subject of many event studies in accounting and finance literature. Conditional on the event of interest, researchers have recently used cross-sectional regressions to examine relations between abnormal returns and firm specific variables. This paper demostrates that non-constant variences and covariances in market model residuals across firms introduced bias in the estimated slope coefficients of the independent variables, i.e., the expected signs of the estimated slope coefficients can be predicted a priori. A method is develope to removed the bias in the estimated slope coefficiets and is found to be effective. This method explicitly takes the dependence among abnormal returns across firms into account. Methods that assume abnormal returns across firms to be independent do not control for such bias.     

A modified Corrado test for assessing abnormal security returns

Event studies typically use the methodology developed by Fama et al. [1969 Fama, E., Fisher, L., Jensen, M. and Roll, R. 1969. The adjustment of stock prices to new information. International Economic Review, 10(1): 1–21. [Crossref] , [Google Scholar]. The adjustment of stock prices to new information. International Economic Review 10, no. 1: 1–21] to segregate a stock's return into expected and unexpected components. Moreover, conventional practice assumes that abnormal returns evolve in terms of a normal distribution. There is, however, an increasing tendency for event studies to employ non-parametric testing procedures due to the mounting empirical evidence which shows that stock returns are incompatible with the normal distribution. This paper focuses on the widely used non-parametric ranking procedure developed by Corrado [1989 Corrado, C. 1989. A nonparametric test for abnormal security price performance in event studies. Journal of Financial Economics, 23(2): 385–95. [Crossref], [Web of Science ®] , [Google Scholar]. A nonparametric test for abnormal security price performance in event studies. Journal of Financial Economics 23, no. 2: 385–95] for assessing the significance of abnormal security returns. In particular, we develop a consistent estimator for the variance of the sum of ranks of the abnormal returns, and show how this leads to a more efficient test statistic (as well as to less cumbersome computational procedures) than the test originally proposed by Corrado (1989 Corrado, C. 1989. A nonparametric test for abnormal security price performance in event studies. Journal of Financial Economics, 23(2): 385–95. [Crossref], [Web of Science ®] , [Google Scholar]). We also use the theorem of Berry [1941 Berry, A. 1941. The accuracy of the Gaussian approximation to the sum of independent variates. Transactions of the American Mathematical Society, 49(1): 122–36. [Crossref] , [Google Scholar]. The accuracy of the Gaussian approximation to the sum of independent variates. Transactions of the American Mathematical Society 49, no. 1: 122–36] and Esseen [1945 Esseen, C. 1945. Fourier analysis of distribution functions: A mathematical study of the Laplace–Gaussian law. Acta Mathematica, 77(1): 1–125. [Crossref], [Web of Science ®] , [Google Scholar]. Fourier analysis of distribution functions: A mathematical study of the Laplace–Gaussian law. Acta Mathematica 77, no. 1: 1–125] to demonstrate how the distribution of the modified Corrado test statistic developed here asymptotically converges towards the normal distribution. This shows that describing the distributional properties of the sum of the ranks in terms of the normal distribution is highly problematic for small sample sizes and small event windows. In these circumstances, we show that a second-order Edgeworth expansion provides a good approximation to the actual probability distribution of the modified Corrado test statistic. The application of the modified Corrado test developed here is illustrated using data for the purchase and sale by UK directors of shares in their own companies.     

Abnormal returns and asymmetric information surrounding strategic and financial acquisitions

Using takeover bids from the United States, we investigate the importance of information asymmetry in self-selection when evaluating the abnormal returns of financial versus strategic takeover targets during a period of possible informed trade. Sample selection bias due to differences in financial versus strategic takeover bid information environments is controlled for using Heckman's model. Results show that takeover announcements are not randomised, indicative of timed announcements, and further that private equity firms exhibit lower price impact post-announcement. We conclude that the long-term financial motive of private equity takeovers, coupled with higher private information pre-announcement, leads to lower abnormal returns post-announcement.     

The information content of implied skewness and kurtosis changes prior to earnings announcements for stock and option returns

We use option prices to examine whether changes in stock return skewness and kurtosis preceding earnings announcements provide information about subsequent stock and option returns. We demonstrate that changes in jump risk premiums can lead to changes in implied skewness and kurtosis and are also associated with the mean and variability of the stock price response to the earnings announcement. We find that changes in both moments have strong predictive power for future stock returns, even after controlling for implied volatility. Additionally, changes in both moments predict call returns, while put return predictability is primarily linked to changes in skewness.     

Caught on tape: Institutional trading,stock returns,and earnings announcements

Many questions about institutional trading can only be answered if one tracks high-frequency changes in institutional ownership. In the United States, however, institutions are only required to report their ownership quarterly in 13-F filings. We infer daily institutional trading behavior from the “tape”, the Transactions and Quotes database of the New York Stock Exchange, using a sophisticated method that best predicts quarterly 13-F data from trades of different sizes. We find that daily institutional trades are highly persistent and respond positively to recent daily returns but negatively to longer-term past daily returns. Institutional trades, particularly sells, appear to generate short-term losses—possibly reflecting institutional demand for liquidity—but longer-term profits. One source of these profits is that institutions anticipate both earnings surprises and post-earnings announcement drift. These results are different from those obtained using a standard size cutoff rule for institutional trades.
