问题如下：
If the return from an asset is positively correlated with interest rates, would you prefer to enter into a long forward contract or a similar long futures contract? Explain.
选项：
解释：
You would prefer to own a long futures contract because daily gains will tend to be invested at a relatively high rate and daily losses will tend to be financed at a relatively low rate.
所以futures和forward 的 选择看的不是购买价格哪个低，而是哪个能带来的收益高？
比如是positive的时候选futures是因为能带来高收益，而不是选forward 因为他定价低？
