ON IMPROVING THE PERFORMANCE OF THE MARKET MODEL

Data on 4,087 securities from 1988 to 1990 are used to test the relation between market model R² and trading volume. Eliminating high-volume observations increases R² by about 10 percent, confirming results previously reported. This study indicates that this improvement is possible by eliminating a small number of observations. It also indicates that this relation between R² and volume is unrelated to firm size.     

THE LONG‐RUN PERFORMANCE OF COMPANIES THAT WITHDRAW SEASONED EQUITY OFFERINGS

We examine the long‐run stock price and operating performance of companies that withdraw seasoned equity offerings (SEOs). Firms that withdraw an offering provide an opportunity to examine whether markets fully adjust to the information conveyed when managers announce the intent to issue shares, independent of any agency problems that might be intensified by the completion of the offering. As in completed seasoned equity offerings, long‐horizon event‐time operating and stock price performance in sample firms is substantially lower than what is observed among control firms. Underperformance is also observed in an equally weighted calendar‐time analysis. Results are consistent with overpricing among small firms that attempt, but then withdraw, SEOs.     

THE EFFECT OF MARKET PROXY REBALANCING POLICIES ON DETECTING ABNORMAL PERFORMANCE

In this paper, effects on the measured abnormal performance of test portfolios are compared against market proxies having the same or different rebalancing policies. Results show that the common practice of comparing buy-and-hold test portfolios with equally weighted market proxies produces lower Jensen [ 7 ] alphas and lower alpha t-values. Comparing buy-and-hold test portfolios with value-weighted market proxies produces higher portfolio betas and alphas, but lower alpha t-values. Finally, comparing buy-and-hold test portfolios with buy-and-hold market proxies produces the most powerful tests of abnormal performance.     

RISK MANAGEMENT FOR MIDDLE MARKET COMPANIES

This article reinforces the message of the one immediately preceding by showing that small to medium‐sized firms have even stronger (non‐tax) motives for hedging risks than their large corporate counterparts. Although middle market companies have traditionally been viewed as less sophisticated than their larger corporate counterparts in the risk management arena, the authors suggest that such companies have become increasingly receptive to new hedging strategies using derivative products. When used appropriately, such products allow companies to stabilize their periodic operating cash flow by eliminating specific sources of volatility such as fluctuations in interest rates, exchange rates, and commodity prices. Smaller companies recognize that a single swing in a budgeted cost can have a catastrophic effect on an entire budget, whereas a larger company can more easily absorb such a cost. Moreover, because the principal owners of mid‐sized firms often have a substantial part of their net worth tied up in the business, they are likely to have a far stronger interest than typical outside shareholders in using risk management to reduce the volatility of corporate profits and firm value. Perhaps most important to owners whose firms rely on debt financing, the greater cash flow stability resulting from active risk management significantly reduces the possibility of financial distress or bankruptcy. In this article, three representatives of Bank of America's risk management practice discuss three different exposures faced by middle market companies—those arising from changes in interest rates, foreign exchange rates, and commodity prices—and show how these risks can be managed with derivatives. Besides shielding companies from financial trouble, risk management is also likely to improve their access to the money and capital markets. By protecting the firm's access to capital, risk management increases the odds that the firm will not be forced to pass up good investment opportunities because of capital constraints or fear of getting into financial difficulty.     

HEDGING PERFORMANCE AND HEDGING OBJECTIVES: TESTS OF NEW PERFORMANCE MEASURES IN THE FOREIGN CURRENCY MARKET

Two related approaches are introduced for measuring the performance of hedging strategies. The first summarizes the risk-return trade-off as a single annotated numerical value, and the second displays it as a performance curve. Two bounded sets of hedging strategies are used to evaluate empirically the performance measures. One set is divided according to whether it best satisfies short or long hedging objectives. Results show that market conditions often provide opportunities to reduce variance and increase expected return. They also suggest that the Commodity Futures Trading Commission's typical definition of “bona fide” hedging should be reconsidered.     

THE RELATIONSHIP BETWEEN FINANCIAL PERFORMANCE AND STOCK MARKET BASED MEASURES OF CORPORATE DIVERSIFICATION

This study examines the relationship between corporate diversification and financial performance. The use of a stock market based measure of diversification allowed a much larger database than in previous studies and overcame the subjective nature of measuring internal diversification. Because previous researchers found that firm size affected performance, size was controlled in this analysis. The authors conclude that there is no statistically significant relationship between the degree of internal diversification and financial performance.
