This paper evaluates various explanations for the profitability of momentum strategies documented in Jegadeesh and Titman (1993) . The evidence indicates that momentum profits have continued in the 1990s, suggesting that the original results were not a product of data snooping bias. The paper also examines the predictions of recent behavioral models that propose that momentum profits are due to delayed overreactions that are eventually reversed. Our evidence provides support for the behavioral models, but this support should be tempered with caution.

Firm sizes and book-to-market ratios are both highly correlated with the average returns of common stocks. Fama and French (1993) argue that the association between these characteristics and returns arise because the characteristics are proxies for nondiversifiable factor risk. In contrast, the evidence in this article indicates that the return premia on small capitalization and high book-to-market stocks does not arise because of the comovements of these stocks with pervasive factors. It is the characteristics rather than the covariance structure of returns that appear to explain the cross-sectional variation in stock returns.

This paper investigates the determinants of leveraged buyout (LBO) activity by comparing firms that have implemented LBOs to those that have not. Consistent with the free cash flow theory, we find that firms that initiate LBOs can be characterized as having a combination of unfavorable investment opportunities (low Tobin's q) and relatively high cash flow. LBO firms also tend to be more diversified than firms which do not undertake LBOs. In addition, firms with high expected costs of financial distress (e.g., those with high research and development expenditures) are less likely to do LBOs.

This paper documents that strategies which buy stocks that have performed well in the past and sell stocks that have performed poorly in the past generate significant positive returns over 3-to 12-month holding periods. We find that the profitability of these strategies are not due to their systematic risk or to delayed stock price reactions to common factors. However, part of the abnormal returns generated in the first year after portfolio formation dissipates in the following two years. A similar pattern of returns around the earnings announcements of past winners and losers is also documented.

Sheridan Titman, Walter Torous, Valuing Commercial Mortgages: An Empirical Investigation of the Contingent- Claims Approach to Pricing Risky Debt, The Journal of Finance, Vol. 44, No. 2 (Jun., 1989), pp. 345-373

This paper empirically investigates a contingent‐claims model of commercial mortgage pricing. We find that the magnitude of the observed default premia for a sample of nonprepayable fixed rate bullet mortgages can be explained by the contingent‐claims model. In addition, the model explains a significant proportion of the period‐to‐period changes in the default premia. However, given an assumed negative correlation between building value changes and interest rate changes, the model's risk structure tends to increase less steeply with increasing maturity than the observed risk structure.
