选项:
A.2,015
B.2,014
C.2,013
解释:
A is correct.
考点:synthetic index fund
解析:
根据公式:买入股票=买入无风险资产+买入期货
我们需要通过买入无风险资产和期货来合成三个月的股票头寸。但是要注意的是,在购买期货的期初,投资者是不需要支付款项的,在合约到期时才进行交割。
那么三个月之后,现金用来投资无风险资产之后的价值为:
500,000,000*(1+3%)0.25
然后再计算用这么多钱可以购买多少份的期货:
因为只能买卖整数份的期货合约,所以要四舍五入,即买入2,015份期货。
根据公式:买入股票=买入无风险资产+买入期货
这个公式是咋推出的?long stock不是=long forward吗
