This article examines the price formation process during dividend announcement day using daily closing prices and transactions data. The authors find that the unconditional positive excess returns, first documented by A. Kalay and U. 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.

We reason that dividend-yield surprises are perfectly correlated with dividend surprises. If investors with preference for dividends are the marginal investors in high-yield stocks, the price reaction to a dividend change should be larger, the higher the anticipated yield of the stock. An examination of over 8,500 dividend changes shows that price reactions to dividend increases are significantly more positive and to dividend decreases significantly more negative for high-yield stocks. Also, the price reactions to dividend changes are larger and the yield effect is stronger for low-priced and small-firm stocks, perhaps because of greater information content and higher transaction costs.

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.
