Assume that you deposit the initial margin and do not withdraw the excess on any given day. Whenever a margin call occurs, you would make a deposit to bring the balance up to meet the initial margin requirement. Fill the appropriate numbers in the blank cells. (Hint: Refer to Table 8.2 in the textbook on p. 272.)

A coffee trader holds a current inventory of coffee worth $1 million at the present price of $1,250 per ton. The standard deviation of the value for the inventory is 0.27.

For the particular grade of coffee in her inventory, the correlation between the futures and spot coffee is 0.85.

You manage a $4 million portfolio, currently all invested in Canadian equities. The beta of the portfolio is 1.25. You believe that the market is on the verge of a big but shortlived downturn. You would move your portfolio temporarily into Tbills, but you do not want to incur the transaction costs of liquidating and reestablishing your equity position. Instead, you decide to hedge your portfolio with threemonth S&P/TSX 60 index futures contracts for one month. Currently, the level of the S&P/TSX 60 index is 425, the threemonth futures price of the S&P/TSX 60 is 428, and one contract is for $200 times the index. The annual riskfree rate is 3%.
a.
