This paper studies the relation between changes in financial investment opportunities and changes in the macroeconomy. States variables, such as the lagged production growth rate, the default premium, the term premium, the short-term interest rate, and the market dividend-price ratio, are shown to be indicators of recent and future economic growth and positively correlated with expected future economic growth. These results offer straightforward interpretations of recent evidence on the forecasts of the market excess return by state variable via their forecasts on the macroeconomy.

The authors examine differences in structural characteristics that lead firms of different sizes to react differently to the same economic news. They find that a small firm portfolio contains a large proportion of marginal firms–firms with low production efficiency and high financial leverage. The authors construct two size-matched indices designed to mimic the return behavior of marginal firms and find that these return indices are important in explaining the time-series return difference between small and large firms. Furthermore, risk exposures to these indices are as powerful as log(size) in explaining average returns of size-ranked portfolios.

This paper studies the relation between changes in financial investment opportunities and changes in the macroeconomy. States variables such as the lagged production growth rate, the default premium, the term premium, the short‐term interest rate and the market dividend‐price ratio are shown to be indicators of recent and future economic growth. Further, the market excess return is negatively correlated with recent economic growth and positively correlated with expected future economic growth. These results offer straightforward interpretations of recent evidence on the forecasts of the market excess return by state variable via their forecasts on the macroeconomy.

We estimate the parameters of Ross's Arbitrage Pricing Theory (APT). Using daily return data during the 1963–78 period, we compare the evidence on the APT and the Capital Asset Pricing Model (CAPM) as implemented by market indices and find that the APT performs well. The theory is further supported in that estimated expected returns depend on estimated factor loadings, and variables such as own variance and firm size do not contribute additional explanatory power to that of the factor loadings.

This paper considers the problem of forming a hedge when there are perceived profit opportunities. We show that the option price obeys a modified Black and Scholes equation. Iterative methods yield the appropriate hedge ratio.

This article tests a theoretical model of the basis and open interest of stock index futures. The model is based on the differences between stock and futures in terms of investors' ability to customize stock portfolios and liquidity. Empirical evidence confirms the model's prediction that increased volatility decreases the basis and increases open interest.
