摘要
This paper uses the expected utility framework to examine the optimal hedging decision for commodities with mean-reverting price processes. The derived results show that when commodity prices follow a mean-reverting process, the optimal hedge ratio differs significantly from the classical results found under standard geometric Brownian motion. Hence, a failure to accommodate mean reversion when it exists can lead to systematic biases in hedging decisions.
