The FTC reported 22, 517 corporate acquisitions during the 1960s compared with 7200 for the period, 1940–1959. The increased employment of this method of corporate growth has generated a number of studies explaining certain segments of the merger movement. Attempts have been made to explain why firms merge, how firms merge, and how mergers have affected subsequent performance of firms. Mergers have been described as consummated to avoid bankruptcy (for the acquired firm), to capitalize upon managerial inefficiencies, to gain from valuation discrepancies, to achieve portfolio diversification, and for synergistic purposes and many other reasons.

Weeden & Co.'s business is that of making markets. We do it in many different types of securities and we take considerable inventory risk in the process. As market makers we learn to be direct in our dealings. “My market is 62 bid; offered at 62½.” “I can offer 5,000 at 62½ net.” The pace and the pressures of the marketplace tend to make us impatient with those who speak in vague terms, who mask their intentions, or who do not know the facts.

We examine the effect of option listing on the immediate stock-price response to earnings announcements. Contrary to prior studies using earlier data, we find firms initiating option trading after 1986 fail to exhibit a significant decline in earnings response. We then examine 420 firms initiating option trading during 1973–1993. In a series of tests controlling for market-wide effects and changing firm size we find some evidence that option listing may actually increase the stock-price response to earnings, but no evidence listing reduces the response. Both longitudinal and cross-sectional tests produce similar results.

The SEC currently requires that firms disclose recent disagreements with their auditors over accounting or auditing matters when a change in auditor is reported. The effectiveness and usefulness of requirements to disclose disagreements have been questioned, and previous empirical research on the issue has been inconclusive. This study investigates the information content of disclosure of the auditor-firm disagreements. The analysis indicates a significant negative market reaction in the week that the Form 8-K is filed with the SEC. This finding is consistent with the position that the disclosure provides information useful to investors.
