Stock Repurchases and Excess Returns: An Empirical Examination

The excess returns associated with repurchase announcements are viewed largely as a reaction to management's statement that the firm's shares are underpriced; management's signal provides new information that enhances the firm's market value. Although earlier studies have found the excess return to be closely related to the premium set by managment, other factors play a part in determining both the market reaction and the premium level set by management. Among these factors ar relative market capitalization, holdings by institutions, immediate alternative uses for cash, level of insider control, recent stock price performance, relative size of the tender offer, and the resultant change in the firm's capital structure.     

Cash Flow, Consumption Risk, and the Cross-section of Stock Returns

I link an asset's risk premium to two characteristics of its underlying cash flow: covariance and duration. Using empirically novel estimates of both cash flow characteristics based exclusively on accounting earnings and aggregate consumption data, I examine their dynamic interaction in a two-factor cash flow model and find that they are able to explain up to 82% of the cross-sectional variation in the average returns on size, book-to-market, and long-term reversal-sorted portfolios for the period 1964 to 2002. This finding highlights the importance of fundamental cash flow characteristics in determining the risk exposure of an asset.

Impact of Earnings,Dividends and Cash Flows on Stock Returns: Case of Taiwan's Stock Market

The study uses Taiwan's stock market, a newly developed market with different characteristics from that of the U.S., as an experimental case to examine the influences of the market's characteristics on the relationship between stock returns and fundamental accounting information, such as earnings, dividends and cash flows. The testing period is from 1990 to 1994, right after the promulgation of Taiwan's accounting standard for statement of cash flows in 1989.Similar to the findings of U.S. studies, the study shows that earnings data is key information for investors. Unlike the U.S. results, however, both operating income and non-operating income are positively related to stock returns. The usefulness of non-operating income to explain stock returns is due mainly to its recurrent characteristic in Taiwan. The market views non-operating income, mostly from disposal of real-estate and short-term equity investments, as a complementary factor to operating income. It is a possible common phenomenon in a booming economy. Unlike from the results of U.S. studies, Taiwan's stock returns are strongly associated with stock dividends. Cash dividends, however, are relatively less important information to the market. The fast booming economy as well as Taiwan's free tax rate on capital gains are the explanations for the different findings. The results also support McNicholes and Dravid's (1990) and etc. results that stock dividends may act as a signal for favorable future earnings. Examining the association between stock returns and cash flow information, the results indicate that stock returns are positively associated with cash flows from both operating and financing activities. The phenomenon implies that the market appreciates not only the cash inflows from operating activities, but also cash inflows from new issues of bonds or stocks for further expansion. It is consistent to Taiwan's booming economy. The finding also supports Ross (1977) and Leland and Pyles' (1977) signaling hypothesis.The study concludes that the relationships between stock returns and fundamental variables are subject to the market's characteristics. The case of the Taiwan stock market shows that usefulness of accounting information depends upon the different roles of the information in the tested market. The results of the study also indicate that directly applying the U.S. experiences without any adjustment may cause incorrect conclusions for empirical studies.     

Relative Excess Returns

Building on a no-arbitrage relationship suggested by Clare, Thomas and Wickens (1994) between the returns on equity, bonds and treasury bills, this paper develops what is termed a 'relative excess returns' approach to the understanding of movements in equity prices. This no-arbitrage relationship is used to derive an explicit measure of excess returns, which incorporates both the excess returns to equity and bonds while netting out any unprofitable (i.e. market efficient) return predictability caused by time variation in the treasury bill rate. This measure can be related to a series of observable variables in a consistent manner and used to construct a trading rule aimed at forecasting excess returns. In a series of empirical experiments, this trading rule appears to be more 'profitable' than both the rule suggested by Clare et al. (1994) and the gilt-equity yield ratio rule (used by many UK analysts to guide investment decisions), and outperforms the strategy of 'buy and hold equity'. More generally, the analysis provides support for the existence of predictable excess returns — returns which cannot be attributed to time-varying excess returns — and for the inefficient market explanation of predictable returns.     

The Weekly Pattern in Stock Returns: Cash versus Futures: A Note

This paper presents tests designed to determine whether the weekly pattern in stock returns continues after the introduction of futures trading on stock indexes and whether the pattern carries over to the futures market. Using data for the SP500, I find that the “Monday effect” does persist in the cash market, but there is no evidence of a similar pattern in the futures market.

Stock Returns and Open-Market Stock Repurchase Announcements

Recent studies document stock price underreactions and overreactions. This evidence is extended by studying open-market stock repurchase announcements. Repurchase announcements were chosen for the study because of the uncertainty regarding the appropriate interpretation of the repurchase announcement. Cross-section regression models are used to test the relation between the reaction to the repurchase announcement and returns in subsequent periods. The results indicate that the market overreacts to repurchase announcements that are deemed to be “good news” by the market. Neither reversal nor drift is observed following repurchase announcements considered to be “bad news” by the market. The results are robust and are not driven by a few influential observations, beta shifts, or bid-ask bounce.     

Earnings Quality Measures and Excess Returns

This paper examines how commonly used earnings quality measures fulfill a key objective of financial reporting, i.e., improving decision usefulness for investors. We propose a stock‐price‐based measure for assessing the quality of earnings quality measures. We predict that firms with higher earnings quality will be less mispriced than other firms. Mispricing is measured by the difference of the mean absolute excess returns of portfolios formed on high and low values of a measure. We examine persistence, predictability, two measures of smoothness, abnormal accruals, accruals quality, earnings response coefficient and value relevance. For a large sample of US non‐financial firms over the period 1988–2007, we show that all measures except for smoothness are negatively associated with absolute excess returns, suggesting that smoothness is generally a favorable attribute of earnings. Accruals measures generate the largest spread in absolute excess returns, followed by smoothness and market‐based measures. These results lend support to the widespread use of accruals measures as overall measures of earnings quality in the literature.     

On Stock Market Returns and Returns on Investment

This article presents general conditions under which it is possible to obtain asset pricing relations from the intertemporal optimal investment decision of the firm. Under the assumption of linear homogeneous production and adjustment cost functions (the Hayashi (1982) conditions), it is possible to establish, state by state, the equality between the return on investment and the market return of the financial claims issued by the firm. This result proves to be, in essence, robust to the consideration of very general constraints on investment and the inclusion of taxes.     

Excess Cash and Shareholder Payout Strategies

On March 19, 2012, Apple announced a program to distribute its “excess” cash to shareholders in the form of dividends and share buybacks. This announcement followed a pattern that is remarkably similar to the one leading up to Microsoft's announcement in 2004. Likewise IBM, the bluest of blue chips, made a path‐breaking decision to initiate share buybacks in the 1980s. And as recently as April 2012, IBM, along with many other large corporations, announced yet another major share buyback program together with an increase in its dividend. These actions underscore the reality that senior management's main job is to allocate capital efficiently—and that efficient allocation of capital means distributing it when necessary. In light of these events, and the demand from shareholders that appears to be driving them, this paper explores analytical and empirical issues related to excess cash and corporate payout policy. In so doing, it provides the outline of an analytical framework for executives when thinking about the allocation of excess cash among competing uses, including deleveraging, growth, special and regular dividends, and share buybacks. The essence of the framework is this: Once companies satisfy their demands for cash based on their expected financial transactions, their targeted capital structure, and prospective investment (mergers and acquisitions) considerations, management should turn its attention to capital structure and shareholder payout decisions. Assuming that the company's capital structure is reasonably close to its target, and that its rating agencies are supportive, management should aim to pay a level of dividends that (1) reflects the underlying strength and stability of their projected earnings streams and that (2) satisfies the expectations of its core shareholders while positioning itself for the future. For more cyclical and otherwise riskier companies, management should also consider the use of stock buybacks or special dividends as a way of paying out the more variable, or unexpected, part of their expected earnings stream.     

Excess Returns to R&D-Intensive Firms

Recent studies indicate that both current R&D investment levels and current or recent changes in R&D investment are positively associated with subsequent excess (risk-adjusted) stock returns. The tentative explanation offered for these results is that shares of R&D-intensive firms are mispriced because investors fail to see through earnings distortions caused by conservative accounting for R&D costs. However, an alternative explanation is that conventional controls for risk do not completely capture the riskiness of R&D-intensive firms, causing measured excess returns for these firms to be biased upward. This study provides evidence useful for distinguishing between the mispricing and risk explanations for R&D-related excess returns. Overall, our empirical results suggest that the positive association between R&D investment levels and excess returns is more likely to result from failure to control adequately for risk than from mispricing. On the other hand, our results do not rule out the possibility of a second source of excess returns that are due to mispricing and that are associated with changes in the level of R&D investment.     

Information Uncertainty and Stock Returns

There is substantial evidence of short‐term stock price continuation, which the prior literature often attributes to investor behavioral biases such as underreaction to new information. This paper investigates the role of information uncertainty in price continuation anomalies and cross‐sectional variations in stock returns. If short‐term price continuation is due to investor behavioral biases, we should observe greater price drift when there is greater information uncertainty. As a result, greater information uncertainty should produce relatively higher expected returns following good news and relatively lower expected returns following bad news. My evidence supports this hypothesis.     

Real Stock Returns and Inflation

This paper develops the relation between the real rate of return on the stock market and changes in the price level using a multiperiod economy with production. The observed relation between real ex post stock returns and inflation is shown to be consistent with equilibrium in an economy with rational investors. The relation between expected real returns and expected inflation is shown to depend on the form of the economy's production function and on the form of investor preferences. When the production function exhibits stochastic constant returns to scale, the model explains the negative relation between expected real returns and expected inflation which has frequently been observed in empirical studies.     

Sports Sentiment and Stock Returns

This paper investigates the stock market reaction to sudden changes in investor mood. Motivated by psychological evidence of a strong link between soccer outcomes and mood, we use international soccer results as our primary mood variable. We find a significant market decline after soccer losses. For example, a loss in the World Cup elimination stage leads to a next‐day abnormal stock return of ?49 basis points. This loss effect is stronger in small stocks and in more important games, and is robust to methodological changes. We also document a loss effect after international cricket, rugby, and basketball games.     

Stock Returns,Expected Returns,and Real Activity

Measuring the total return variation explained by shocks to expected cash flows, time-varying expected returns, and shocks to expected returns is one way to judge the rationality of stock prices. Variables that proxy for expected returns and expected-return shocks capture 30% of the variance of annual NYSE value-weighted returns. Growth rates of production, used to proxy for shocks to expected cash flows, explain 43% of the return variance. Whether the combined explanatory power of the variables—about 58% of the variance of annual returns—is good or bad news about market efficiency is left for the reader to judge.     

Investment Plans and Stock Returns

When the discount rate falls, investment should rise. Thus with time-varying discount rates and instantly changing investment, investment should positively covary with current stock returns and negatively covary with future stock returns. Aggregate nonresidential U.S. investment contradicts both these implications, probably because of investment lags. Investment plans, however, satisfy both implications. These investment plans, from a U.S. government survey of firms, are highly informative measures of expected investment and explain more than three-quarters of the variation in real annual aggregate investment growth. Plans have substantial forecasting power for excess stock returns, showing that time-varying risk premia affect investment.     

Stock Market Returns and Consumption

This paper employs Swedish data on households' stock holdings to investigate how consumption responds to changes in stock market returns. We instrument the actual capital gains and dividend payments with past portfolio weights. Unrealized capital gains lead to a marginal propensity to consume of 23% for the bottom 50% of the wealth distribution and about 3% for the top 30% of the wealth distribution. Household consumption is significantly more responsive to dividend payouts across all parts of the wealth distribution. Our findings are consistent with households treating capital gains and dividends as separate sources of income.     

Cash Flows and Discount Rates,Industry and Country Effects and Co‐Movement in Stock Returns

We apply the Campbell decomposition to industry‐by‐country, national, global industry, and world stock index returns using 1995–2003 data. World, global industry, and country factors are all important for each of the two key components of stock returns: news about future dividends and news about future discount rates. Furthermore, the world component of future discount rates is more important than the idiosyncratic component, while the reverse is true for news about future dividends. Our results are broadly consistent with co‐movement in future discount rates arising from perceptions of common elements of risk in international equity markets.
