Question $1.($Futures and Margin Calls$)(65)$ You are a fund manager and would like to trade some S$-$index futures. S$-$index is an equity index. For the S$-$index futures, the maintenance margin is $$11,200,$ and the initial margin is $$12,320.$ Note that the S$-$index futures contract has a contract unit of $50,$ or one S$-$index futures contract has a notional value of $50\backslash$times S$-$Index. The futures price data in the Excel spreadsheet do not take the multiplier $50$ into account.
