Distinguish between margin in the securities markets and margin in the futures markets, and explain the role of initial margin, maintenance margin, variation margin, and settlement in futures trading.
B is correct because on any day when the balance in the margin account falls below the maintenance margin, the trader must deposit sufficient funds to bring the balance back up to the initial margin requirement. This additional amount is called the “variation margin.” Therefore, $100 – $40 = $60 variation margin.

A.$ 11.91
B.$ 13.26
C.$ 14.61
正确答案:B
答案解析：收益为：$ 38.60- $ 25.34 = $ 13.26。在计算期权价值如最大最小边界时，需要考虑未来预期股利的折现；在计算期权收益时，则只用考虑行权价和实际价格的差。题目中，是看跌期权，股票价格低于行权价时的支付是股票价格减去行权价。
