Recent theoretical work suggests that definitions of market efficiency that allow for the possibility of time-varying risk-premia will generally lead to return sign predictability. Consistent with this theory, we show that a logit model based on the lagged value of the market risk premium is...

Much of the empirical work on hedging exchange rate exposure in portfolios of financial assets has used a unitary hedge ratio, or a currency overlay. Alternatively, the currencies themselves can be treated as assets and the position in them optimized. This study empirically tests whether the ex...

Much of the early research on contrarian performance adjusts for risk using a Jensen's alpha estimated with in-sample returns in either real time or event time. The use of in-sample returns means that beta is estimated with the same observation period returns it is intended to risk adjust. This...

We find that for a sample of call options on stocks with low returns in the prior year, the implied volatilities increase as the year-end approaches. On the other hand, we do not detect an increase in the volatilities implied from the put options on the same stocks over the same dates. This is...
