摘要：Most models of market volatility use either past returns or ex post volatility to forecast volatility. In this paper, the dynamic behavior of market volatility is assessed by forecasting the volatility implied in the transaction prices of Standard & Poor's 100 index options. We test and reject the hypothesis that volatility changes are unpredictable. However, while our statistical model delivers precise forecasts, abnormal returns are not possible in a trading strategy (based on daily out-of-s...

摘要：We investigate the relation between the Value Line enigma and post-earnings-announcement drift. The ability of Value Line's 'timeliness' ranks to predict future abnormal returns is well-documented. However, we show that most rank changes occur within eight trading days of an earnings announcement. Once we control for post-earnings-announcement drift, differences in abnormal returns across Value Line timeliness ranks are no longer significant. Moreover, we find that timeliness ranks have no pre...

摘要：This paper examines the post-acquisition performance of large bank mergers between 1982 and 1987. On the whole, the merged banks outperform the banking industry. Their better performance appears to result from improvements in the ability to attract loans and deposits, in employee productivity, and in profitable asset growth. Further, we find a significant correlation between announcement-period abnormal stock returns and the various performance measures, showing that market participants are ab...

摘要：We examine employee stock ownership plan (ESOP) announcements to study the effects of an increase in managerial voting rights without a proportional increase in the ownership of cash flow claims. Our finding that when managers initially control few votes firm value increases with the fraction of shares contributed to the ESOP supports the view that managerial vote control serves shareholder interests. Conversely, the decrease in firm value with larger contributions to the ESOP when managers in...

摘要：We estimate the conditional distribution of trade-to-trade price changes using ordered probit, a statistical model for discrete random variables. This approach recognizes that transaction price changes occur in discrete increments, typically eighths of a dollar, and occur at irregularly-spaced time intervals. Unlike existing models of discrete transactions prices, ordered probit can quantify the effects of other economic variables like volume, past price changes, and the time between trades on...

摘要：Average common stock price responses to convertible preferred stock calls are significantly negative only when firms employ underwriters to assure conversion. Previous work reports similar results for convertible bond calls; we find that the stock price reaction does not depend upon the type of convertible security being called. The results support the idea that managers are more likely to have calls underwritten the more unfavorable their private information about firm value.

摘要：This study investigates the returns to acquiring-firm stockholders in federally assisted mergers in the savings and loan industry. It is unique in that (a) these mergers are arranged and subsidized by government regulators and (b) they occur in a single industry, one plagued by well-publicized financial difficulties. The contribution of resources by the federal government creates the possibility of wealth transfers from the government to owners of the acquiring firms. We find, consistent with ...

摘要：There is a significant foreign influence on the risk premium for U.S. assets. Using a bivariate GARCH-in-mean process, we find that the conditional expected excess return on U.S. stocks is positively related to the conditional covariance of the return of these stocks with the return on a foreign index but is not related to its own conditional variance. Further, we are unable to reject the international version of the CAPM. We present evidence for different model specifications, multiple-day re...

摘要：We examine post-acquisition performance for the 50 largest U.S. mergers between 1979 and mid-1984. Merged firms show significant improvements in asset productivity relative to their industries, leading to higher operating cash flow returns. This performance improvement is particularly strong for firms with highly overlapping businesses. Mergers do not lead to cuts in long-term capital and R & D investments. There is a strong positive relation between postmerger increases in operating cash flow...

摘要：This study investigates the impact of Pennsylvania Senate Bill 1310 on the share prices of Pennsylvania corporations. Considered the most severe of the second-generation antitakeover laws, the statute limits the ability of shareholders to challenge management through the proxy process and eliminates the traditional fiduciary obligation of directors to promote shareholders' interests. We find that PA SB1310 significantly decreased share values, and estimate the loss to shareholders of Pennsylva...
