The multiplier for a futures contract on a stock market index is $$55.$ The maturity of the contract is one year, the current level of the index is $$3,500,$ and the risk$-$free interest rate is $0\mathrm{.}4\%$ per month. The dividend yield on the index is $0\mathrm{.}2\%$ per month. Suppose that after one month, the stock index is at $3,550.$

Required:

Find the cash flow from the mark$-$to$-$market proceeds on the contract. Assume that the parity condition always holds exactly.

Find the holding$-$period return if the initial margin on the contract is $$10,100.$
