The multiplier for a futures contract on a certain stock market Index is $50. The maturity of the contract is one year, the current level of the index is 2,000, and the risk-free interest rate is 0.4% per month. The dividend yield on the index is 0.4% per month. Suppose that after one month, the stock index is at 2,160. a. Find the cash flow from the mark-to-market proceeds on the contract. Assume that the parity condition always holds exactly. (Do not round intermediate calculations. Round your answer to 2 decimal places.) Cash flow b. Find the holding period return if the initial margin on the contract is $5,000. (Do not round Intermediate calculations, Round your answer to 2 decimal places.) Holding period return
