Commodity Futures Hedging, Risk Aversion and the Hedging Horizon

This paper examines the impact of management preferences on optimal futures hedging strategy and associated performance. Applying an expected utility hedging objective, the optimal futures hedge ratio is determined for a range of preferences on risk aversion, hedging horizon and expected returns. Empirical results reveal substantial hedge ratio variation across distinct management preferences a...

Hedging and Value at Risk

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 the reduction in standard deviation with the reduction in 99% VaR for thirteen cross-hedged currency p...

Liquidity Risk Hedging

Long-term bonds are exposed to higher interest-rate risk, or duration, than short-term bonds. Conventional interest-rate risk management prescribes that a firm structure the maturity of its liabilities in order to hedge the duration of its long-term assets (?). By doing so, the firm’s assets and liabilities move in lockstep, and its net equity is shielded from (at least small) movements in inte...

Delta-hedging Vega Risk?

In this article we compare the Profit and Loss arising from the delta-neutral dynamic hedging of options, using two possible values for the delta of the option. The first one is the Black– Scholes implied delta, while the second one is the local delta, namely the delta of the option in a generalized Black–Scholes model with a local volatility, recalibrated to the market smile every day. We expl...
