Question 2 [2 marks]
A cocoa merchant holds a current inventory of goods worth $10 million at present prices of $1,250 per metric ton. The standard deviation of returns for the inventory is 0.22. She is considering a risk-minimisation hedge of her inventory using the cocoa contract of the Coffee, Cocoa and Sugar Exchange. The contract size is 10 metric tons. The volatility of the futures is 0.44. For the particular grade of cocoa in her inventory, the correlation between futures and spot cocoa is 0.88. Compute the risk-minimisation hedge ratio and determine how many contracts she should trade.
