同学你好，
第一年相当于初始投资30，涨到了35，又有了5的分红，所以收益是35+5-30，收益率即为（35+5-30）/30
这里的关键是第一年末虽然没有抛售那只成本为30的股票，但是实际上这只股票也涨到了35，因为这个时候新买入就需要用35买了。
但是要注意，计算第二年收益率的时候，就需要按照两只股票的成本都是35来计算了。

感觉我们没的选，必须要这样理解才行，题目陷阱还是很多的😅

老师，好： 这道题目与No.PZ2015120604000032一样，只不过这个求time-weighted rate。但我认为这个题目第一个应该就是35，不是40。一年以后分红就5就代表股票涨到35了，而不是40。应该一个HPR就是35-30。这样也符合032那道题C01为-30的现金流计算。所以我觉得这样理解应该是正确的。
