Question

Suppose that the standard deviation of quarterly changes in the prices of a commodity is $0.65, the standard deviation of quarterly changes in a futures price on the commodity is $0.81, and the coefficient of correlation between the two changes is 0.8. What is the optimal hedge ratio for a three-month contract? What does it mean?

Answer 1

Answer:

The optimal hedge is 0.642 and it means that the size of the future positions should be 64.2% of the exposure of the company in a 3 month-hedge.

Explanation:

optimal hedge ratio

= coefficient of correlation*(standard deviation of quarterly changes in the prices of a commodity/standard deviation of quarterly changes in a futures price on the commodity)

= 0..8*(0.65/0.81)

= 0.642

Therefore, The optimal hedge is 0.642 and it means that the size of the future positions should be 64.2% of the exposure of the company in a 3 month-hedge.
