INTEREST RATE SENSITIVITY OF BANK STOCK RETURNS: SPECIFICATION EFFECTS AND STRUCTURAL CHANGES

In this paper the interest rate sensitivity of bank stock returns under alternative econometric specifications and the changes in the sensitivity over time are studied. Results indicate that the sensitivity depends on the econometric specification and the period considered. Bank stock returns show a sensitivity to long-term government security returns and innovations, but not to short-term government security returns and innovations except under one specification. Since 1980, banks seem to have reduced their interest rate risk exposure. Finally, while long-term returns are positively associated with stock returns, short-term returns show a positive association only since 1980.     

OTC MARKET SWITCHING AND STOCK RETURNS: SOME EMPIRICAL EVIDENCE

In this study the effect on the common stock returns of 278 firms that switched OTC market segments from 1982 to 1987 is examined. It is hypothesized that abnormally positive returns are associated with news of the move from the NASDAQ to the NASDAQ National Market System (NMS) and that the market responds more favorably during pre-NMS inclusion for stocks with low versus high liquidity before switching. Using event study methodology, results support these hypotheses. Unlike post-listing studies, the evidence reveals no anomalous return behavior during the post-NMS inclusion period studied.     

A NOTE ON THE BEHAVIOR OF SECURITY RETURNS: A TEST OF STOCK MARKET OVERREACTION AND EFFICIENCY

Researchers have debated stock market efficiency for years and have found several apparent anomalies, among them the overreaction investment strategy. In a sample of virtually all AMEX and NYSE stocks over twenty-one years, it is demonstrated that abnormal returns earned in one year are positively related to the abnormal returns earned in the next year. This evidence is contrary to the overreaction investment philosophy.     

BUSINESS CYCLES AND STOCK MARKET RETURNS: EVIDENCE USING INDUSTRY-BASED PORTFOLIOS

Much evidence has emerged recently that suggests stock returns are predictable. In representative agent consumption-based asset pricing models, asset returns are related to aggregate output and consumption through changes in the intertemporal marginal rate of substitution. An alternative view is that the amount of variation required in the intertemporal marginal rate of substitution is too large to be rationally explained. We shed further light on this debate by investigating whether the stock returns of certain sectors of the economy can predict future market returns even after controlling for the information contained in the aggregate market index. In the consumption-based models, aggregate output and consumption affect the discount rates of all assets synchronously; no particular sectoral return should have any more predictive ability than the others. We find evidence that the stock returns of five industry-based portfolios have significant information about future market returns that is not in the market index. This stylized empirical result is not consonant with existing models relating output to stock returns.     

STOCK PRICE AND DEGREE OF NEGLECT AS DETERMINANTS OF STOCK RETURNS

In prior research the neglected firm effect persists even after controlling for firm size. Several recent studies show that the size effect is a stock price effect. In the present study we investigate whether excess returns on neglected stocks are a manifestation of a stock price effect. Although material evidence supporting an independent neglected firm effect is still found, results are much weaker than in prior studies. Examining a large sample of New York Stock Exchange and American Stock Exchange stocks from 1977 to 1988, we find that both January and non-January months do not have a statistically significant neglect effect after controlling for a price effect.     

STOCK REPURCHASES AND SECURITYHOLDER RETURNS: A CASE STUDY OF TELEDYNE

This study examines securityholder returns around nine major repurchase announcements and 10 other repurchase-related announcements by the Teledyne Corporation between 1972 and 1984. Statistically significant positive excess returns to common stock and convertible preferred stockholders are documented. Contrary to prior research that investigated the average response to repurchase announcements, however, there is a wealth transfer from bondholders to stockholders. Bondholder returns around the repurchase announcements are significantly negative. These returns are examined for each announcement and each bond issue.     

FILTER RULE TESTS OF THE ECONOMIC SIGNIFICANCE OF SERIAL DEPENDENCIES IN DAILY STOCK RETURNS

In this paper we examine the ability of filter rules to predict variation in expected daily returns for a sample of 120 Dow Jones and S&P 100 stocks from 1963 through 1989. Equally weighted portfolios of filter-rule-traded stocks consistently outperform a buy-and-hold portfolio of the same stocks before accounting for transaction costs. The difference in returns between filter rule and buy-and-hold portfolios is eliminated by one-way transaction costs of 12 basis points. The economic significance of daily stock return autocorrelations is estimated. A marginal 1 percent increase in a first-order autocorrelation increases filter rule returns by an estimated 3.84 percent.     

THE INTERACTION OF MONETARY POLICY AND STOCK RETURNS

The “irrational exuberance” of the stock market in the late 1990s led to a discussion of the appropriate policy response by monetary authorities. Any response would be contingent on the stock market reaction to policy shocks. In this study, I employ a structural vector autoregression to estimate the response of the stock market returns to innovations in the federal funds rate. The role of the stock market in the Federal Reserve policy rule can also be examined empirically.     

STOCK MARKET RETURNS AND INFLATIONARY EXPECTATIONS: ADDITIONAL EVIDENCE FOR 1975–1979

This research investigates the impacts that inflationary expectations and errors in those expectations had upon the stock market during 1975 to 1979. Expected rates of inflation were obtained via (1) Box-Jenkins time-series analysis and (2) naive extrapolation. Statistical analysis indicates only weak support for a Fisher effect in determining stock prices. However, the analysis consistently indicates that unanticipated changes in inflation are negatively related to stock market returns.
