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.
这里跟我想的有一点点出入，我看到答案写着只要是正相关，那么应该投资futures， 涨了会daily gain, 跌了可以用降低的利率去还借债利息。
但是我在想，这里假如我预期未来利率是下降的，我又知道它是正相关，我futures注定会daily loss了，我难道不该投资short?
或者说，我是为了锁定利率，一定要long, 那么既然futures & foward殊途同归，我应该选择最后一天才结算的forward,中间的损失不用拿来还margin, 保证我的流动性才对吧？
