中文解析：
本题考察的是使用期货合约管理外汇风险。
美国的投资者在加拿大有一笔为期6个月的投资，在投资期结束的时候将卖掉这个资产，将收到加拿大元，然后再转换回本币美元。
因此该投资者担心6个月后加拿大元会贬值，他可以通过卖出对应的期货合约来锁定6个月后加拿大元换回美元的汇率，从而对冲掉汇率的风险。
需要的合约数量可以用该资产的售价除以期货合约的价值来计算。
his investment asset is in Canada.
he is concerned the Canadian dollar will depreciate 6 months later.
to hedge fully, he should short the futures contract with principal equal to the value of underlying.
为啥还要写明是多少份合约呢？ 这个题就是 short futures啊，感觉没什么好多说的
