Of course, past performance is no guarantee of future results, and two cases do not constitute a statistically significant sample. Just because the dollar weakened twice during the last two periods of Fed tightening does not prove that the same thing will happen again.
当然，过去的表现绝不意味着未来的结果，两次例子也绝不构成有统计意义的样本。仅仅因为美元在前两次美联储紧缩周期中贬值并不代表未来也会发生同样的事。
