This paper investigates the extent to which discounts and premiums provide information about future expected rates of return on closed-end investment company shares. It is found that discounted fund shares, adjusted for risk, tended to outperform the market in the period 1940 to 1975. Funds selling at a premium appear to have been bad investments over the same time period. On the basis of these results it is argued that the two-parameter capital asset pricing model does not describe the return generating process of closed-end funds. Other potential areas to search for breakdowns in two-parameter pricing are suggested.

This paper presents a model of stock price reactions to partially anticipated events. The model formalizes the intuition that stock price reactions reflect both the economic importance of events and the extent to which events are surprises. Unbiased estimates of the economic importance of partially anticipated events must combine stock price reactions to events with stock price movements in periods when no event occurs. The model is used to estimate the value of acquisition attempts made by frequently acquiring firms. For a sample of thirty active acquirers, the evidence indicates that acquisition attempts were profitable investment projects.

We investigate the implication of clientele theories that changes in dividend policy should result in a marked increase in trading volume as shareholder clienteles change. With 192 firms announcing their first cash dividend we document both an increase in trading volume and firm value around the announcement date. We integrate these results to distinguish between the volume response to good news about the future and clientele adjustments to a change in dividend policy. Our results suggest that volume increases primarily in response to the signal about future earnings contained in the dividend. Clientele adjustments are small.

We measure the impact of acquisitions activity on firm value by differentiating between specific merger events and programs of acquisition activity. Based on a sample of conglomerate acquirers, we find significantly positive abnormal performance associated with the announcement of acquisitions programs and significantly negative performance associated with certain institutional changes of 1967–1970 relating to acquisition activity (the Williams Amendments, the 1969 Tax Reform Act, and APB Opinions 16 and 17). Our results support the hypotheses that acquisitions activity had a favorable ex ante impact on the value of firms announcing an intention to engage in acquisitions, and that some of the institutional changes reduced the expected profitability of future acquisitions activity. The basic results of studies of mergers and tender offers are reviewed and their consistency with our findings highlighted.
