The non-normality of financial asset returns has important implications for hedging. In particular, in contrast with the unambiguous effect that minimum-variance hedging has on the standard deviation, it can actually increase the negative skewness and kurtosis of hedge portfolio returns. Thus...

Models of the time-varying conditional minimum-variance hedge ratio (MVHR) typically do not provide a significant improvement in terms of hedging performance over the unconditional MVHR model. In view of the widely documented success of conditional volatility models (on which models of the...

This paper tests the expectations hypothesis of the term structure using cross-section bond yield data. A long series of monthly cross-section regressions is estimated using zero coupon bond yields for maturities from two months to thirty-five years. The expectations hypothesis is tested using...

The expectations hypothesis of the term structure of interest rates implies that the spread between short and long bond yields should forecast next period's change in the long yield. Regression based tests have systematically rejected the expectations hypothesis, with estimated coefficients far...

In this paper, we show that although minimum-variance hedging unambiguously reduces the standard deviation of portfolio returns, it tends to increase portfolio kurtosis and consequently the effectiveness of hedging in terms of a more general measure of risk such as VaR is uncertain. We compare...

In this paper, we develop a momentum trading strategy based on the low frequency trend component of the spot exchange rate. Using, alternately, kernel regression and the high-pass filter of Hodrick and Prescott (1997), we recover the non-linear trend in the monthly exchange rate and use...

The expectations hypothesis of the term structure has been decisively rejected by a large empirical literature that spans several decades. In this paper, using a newly constructed dataset of synthetic zero coupon bond yields, we show that evidence against the expectations hypothesis became very...

There has recently been renewed interest in the intraday range (defined as the difference between the intraday high and low prices) as a measure of local volatility. Recent studies have shown that estimates of volatility based on the range are significantly more efficient than estimates based on...

In this article, it is shown that although minimum‐variance hedging unambiguously reduces the standard deviation of portfolio returns, it can increase both left skewness and kurtosis; consequently the effectiveness of hedging in terms of value at risk (VaR) and conditional value at risk (CVaR)...

When using derivative instruments such as futures to hedge a portfolio of risky assets, the primary objective is to estimate the optimal hedge ratio (OHR). When agents have mean‐variance utility and the futures price follows a martingale, the OHR is equivalent to the minimum variance hedge...
