Time Variation of Ex-Dividend Day Stock Returns and Corporate Dividend Capture: A Reexamination

This paper documents some empirical facts about ex-day abnormal returns to high dividend yield stocks that are potentially subject to corporate dividend capture. We find that average abnormal ex-dividend day returns are uniformly negative in each year after the introduction of negotiated commission rates and that time variation in ex-day returns during the negotiated commission rates era is consistent with corporate tax-based dividend capture. Ex-day returns are more negative when the tax advantage to corporate dividend capture is greatest and more positive when increases in transaction costs and risk reduce incentives to engage in corporate tax-based dividend capture.     

Determinants of Corporate Dividend Capture

This paper uses ex-dividend day returns to show that corporate dividend capture in utility stocks depends upon transaction costs, the three month treasury bill rate, unsystematic risk and dividend yield. The paper finds that the data do not support the same determinants for dividend capture in non-utility stocks. Tests on data from before and after the Tax Reform Act of 1986 do not show conclusively that the Tax Reform Act reduced the prevalence of dividend capture.     

Do Tax Law Changes Influence Ex-Dividend Stock Price Behavior? Evidence from 1926 to 2005

We test the Elton and Gruber model of ex-dividend stock pricing over a period spanning all US tax law changes since 1926. Our results indicate that price drop ratios (ΔP/D) and ex-day returns are related to dividend and capital gains tax rates in the theorized manner. Consistent with tax clienteles, we also find that ex-day price movements of higher dividend yield stocks are driven more by corporate tax rates, while lower yield stocks are more influenced by personal rates. Finally, we demonstrate that the positive relationship between ΔP/D and the dividend yield becomes stronger as the tax differential | t_d− t_cg | widens.     

Time-Series Variation in Dividend Pricing

Ex-dividend day returns vary over time. The ex-day returns of high-yield stocks are persistently positive for some time periods and negative for others; in contrast, ex-day returns of low-yield stocks are always positive and less variable. We are unable to explain the variation with changes in the tax code, but we do find a strong effect for the introduction of negotiated commissions. We find evidence that corporate dividend capturing is affecting ex-day returns and confirm the findings of Gordon and Bradford (1980) that the price of dividends is countercyclical.     

Ex-Day Behavior: Tax or Short-Term Trading Effects

This study examines the behavior of share prices around the ex-dividend dates before and after the introduction of the 1988 Income and Corporation Taxes Act that reduced substantially the tax differential between dividends and capital gains in the United Kingdom. We find that, in the pre-1988 period when the differential taxation of dividends and capital gains is high, ex-day returns are positive and significant. In contrast, in the post-1988 period, ex-day returns are, in most cases, negative and insignificant. Further analysis reveals that, while ex-day returns are significantly related to dividend yield and to the length of the settlement period, they are not affected by the commonly used measures of transaction costs, such as the bid-ask spread and trading volume, or by the day of week, month of the year, type of dividend distribution, or number of days to the actual receipt of the cash dividend. We conclude that taxation affects significantly ex-day share prices in the United Kingdom.     

HEDGED DIVIDEND CAPTURE AND EX-DAY RETURNS: AN EMPIRICAL UPDATE

We find that the magnitude of abnormal ex-day returns exhibited by US equities diminished in 1987 and 1988, subsequent to the US Tax Reform Act of 1986. We also report the results of a dividend capture strategy, hedged with the sale of stock index futures contracts. Hedging removes more than 50 percent of the risk of dividend capture, and even after transactions costs, can provide returns in excess of buying and holding the market portfolio of equities.     

Reduction of Constraints on Arbitrage Trading and Market Efficiency: An Examination of Ex-Day Returns in Hong Kong after Introduction of Electronic Settlement

Previous research documents positive ex-dividend day returns in excess of one percent in the unique institutional setting of Hong Kong, where neither dividends nor capital gains are taxed. Short-term arbitrage trades around the ex-day were hampered by physical settlement procedures. After the recent switch to an electronic settlement system, which enables such trades, ex-day abnormal returns have declined to an insignificant 0.17 percent. This drop is more pronounced for high-yield stocks, which are more likely to attract dividend capture trading. The evidence points to the crucial role of short-term traders in ensuring the pricing efficiency of financial markets.     

Ex-dividend returns: The Mexican puzzle

We study ex-dividend returns in Mexico, where an imputation system entitles individual investors to a net dividend tax credit. Based on taxation, we expect ex-day abnormal returns to be negative or at most zero in Mexico. However, they are significantly positive. Because ex-day returns are positive even for stocks restricted to Mexican nationals, they are not attributable to foreign stockholders’ tax considerations. None of the market microstructure-based hypothesis in the literature can explain these positive ex-day returns. Ex-day returns in Mexico are a puzzle.     

Ex-Dividend Day Stock Price Behavior: The Case of the 1986 Tax Reform Act*

This paper analyzes the behavior of stock prices around ex-dividend days after the implementation of the 1986 Tax Reform Act that dramatically reduced the difference between the tax treatment of realized long-term capital gains and dividend income in 1987 and completely eliminated the differential in 1988. We show that this tax change had no effect on the ex-dividend stock price behavior, which is consistent with the hypothesis that long-term individual investors have no significant effect on ex-day stock prices during this time period. The results indicate that the activity of short-term traders and corporate traders dominates the price determination on the ex-day.     

The effects of dividend yield and dividend policy on common stock prices and returns

This paper suggests that it is not possible to demonstrate, using the best available empirical methods, that the expected returns on high yield common stocks differ from the expected returns on low yield common stocks either before or after taxes. A taxable investor who concentrates his portfolio in low yield securities cannot tell from the data whether he is increasing or decreasing his expected after-tax return by so doing. A tax exempt investor who concentrates his portfolio in high yield securities cannot tell from the data whether he is increasing or decreasing his expected return. We argue that the best method for testing the effects of dividend policy on stock prices is to test the effects of dividend yield on stock returns. Thus the fact that we cannot tell, using the best available methods, what effects dividend yield has on stock returns implies that we cannot tell what effect, if any, a change in dividend policy will have on a corporation's stock price.     

Trading Behavior and the Unbiasedness of the Market Reaction to Dividend Announcements

This article examines the price formation process during dividend announcement day, using daily closing prices and transactions data. We find that the unconditional positive excess returns, first documented by Kalay and Loewenstein (1985) , are higher for small-firm and low-priced stocks. Price volatility and trading volume also increase during this period. Examination of trade prices relative to the bid-ask spread and volume of trades at bid and asked prices shows that the excess returns cannot be attributed to measurement errors or to spillover effects of tax-related ex-day trading. Rather, the price behavior is related to the absorption of dividend information.     

Lost in translation: Delayed ex-dividend price adjustments of Hong Kong ADRs

Previous research documents that Hong Kong stocks have a full ex-dividend price adjustment consistent with dividends and capital gains being tax free. We examine ex-dividend price behavior of Hong Kong ADRs to assess the impact of differing tax environments in US and Hong Kong. These ADRs typically go ex-dividend before their underlying stock. They experience significant abnormal returns of 1.16% on their ex-day; the average ex-day price drop is only 30% of the dividend. However, ADR prices drop when the underlying stock goes ex-dividend subsequently. The cumulative ADR price drop is equal to the dividend. Thus, the ADR ex-dividend adjustment resembles that of the underlying stock, consistent with home country tax laws governing ADR price behavior. Neither liquidity nor transaction costs can explain the anomalous delayed ex-dividend adjustment of ADRs.     

Stock Returns, Dividend Yields, and Taxes

Using an improved measure of a common stock's annualized dividend yield, we document that risk-adjusted NYSE stock returns increase in dividend yield during the period from 1963 to 1994. This relation between return and yield is robust to various specifications of multifactor asset pricing models that incorporate the Fama–French factors. The magnitude of the yield effect is too large to be explained by a "tax penalty" on dividend income and is not explained by previously documented anomalies. Interestingly, the effect is primarily driven by smaller market capitalization stocks and zero-yield stocks.     

An Examination of Ex-Dividend Day Stock Price Movements: The Case of Nontaxable Master Limited Partnership Distributions

This study examines the unit (stock) price and volume behavior of master limited partnerships (MLP) around the ex-dividend day. Since the dividends of MLPs are not taxable to the unitholder, tax based hypotheses predict no abnormal unit movements around the ex-day. Significant positive excess returns and volume are found before the ex-dividend day, and significant negative excess returns are found on the ex-dividend day. The findings which are not significantly impacted by the Tax Reform Act of 1986 suggest ex-day stock movements are not solely a function of investor marginal tax rates or corporate trading behavior.     

Payout Policy Tax Clienteles,Ex‐dividend Day Stock Prices and Trading Behavior in Germany: The Case of the 2001 Tax Reform

This paper examines the impact of the German 2001 tax reform, where Germany switched from a full imputation system to a classical system. Theory suggests that both price drop ratios and trading volume decrease following the reform. We document a significant reduction in the valuation of net dividends–in particular for high dividend yield stocks–and weakening payout policy tax clienteles. Ex‐dividend day returns are likely to be driven by short‐term traders. Though the reform removed incentives for cross‐border dividend stripping and reduced tax heterogeneity among investors, we show that the high trading volume around ex‐dividend days persists.     

Capital Structure and the Ex‐Dividend Day Return

We apply an option‐pricing framework to the ex‐dividend behavior of common stocks. The framework explains the observed behavior of positive returns on the ex‐dividend day and predicts that ex‐dividend day returns will be higher for firms with greater financial leverage. Empirical testing supports the prediction. In contrast to prior studies, we find that dividend‐capture activity has no significant impact on ex‐dividend behavior, and we offer an explanation based on the importance of tick intervals.     

Did the 1986 Tax Reform Act Affect Market Reactions to Stock Splits?: A Test of the Tax-Option Hypothesis

This paper tests the prediction of the tax-option hypothesis that the market impact of stock splits would be reduced by the 1986 Tax Reform Act which eliminated the difference between long- and short-term capital gains tax rates. The results show significant excess returns on stock split announcement and ex-days even after 1986. The announcement and ex-day excess returns are similar in different periods before and after the Act. Further, there is no significant relationship between announcement excess returns and increase in returns volatility following splits. These findings are inconsistent with the tax-option hypothesis.     

Taxes,dividend yields and returns in the UK equity market

The higher rate of taxation on dividend income relative to capital gains has been offered as an explanation for the positive relation between stock returns and dividend yields among US firms. In the UK the relative tax rates are the reverse of those in the US. Thus, UK data provides an independent test of the tax-based approach to explaining the relation between stock returns and dividend yields. We find that high yielding stocks earn positive risk adjusted returns, whereas low yielding stocks earn negative risk adjusted returns. We also detect evidence of non-linearity in the performance of zero-dividend stocks. Controlling for firm size, seasonality and market risk we find a significant positive relation between dividend yields and returns. We conclude that the evidence is inconsistent with a tax-based explanation.     

CONSIDERING DIVIDEND STABILITY IN THE RELATION BETWEEN DIVIDEND YIELDS AND STOCK RETURNS

Previous studies show that firms with long records of paying stable dividends are unique. However, research on the relation between dividend yields and stock returns focuses on shorter-term dividend yield measures without considering long-term dividend stability. This article shows that high-yield stocks are not in fact homogeneous, but that stocks with high yields and stable dividends behave differently from stocks with only a high yield. These differences persist even after controlling for firm size, the January effect, and systematic risk, suggesting distinctive risk characteristics for stocks with both high yields and stable dividends.     

The dividend month premium

We find an asset pricing anomaly whereby companies have positive abnormal returns in months when they are predicted to issue a dividend. Abnormal returns in predicted dividend months are high relative to other companies and relative to dividend-paying companies in months without a predicted dividend, making risk-based explanations unlikely. The anomaly is as large as the value premium, but less volatile. The premium is consistent with price pressure from dividend-seeking investors. Measures of liquidity and demand for dividends are associated with larger price increases in the period before the ex-day (when there is no news about the dividend) and larger reversals afterward.
