问题如下：
Drew, an analyst from an investment company, recently gathered the following information for a price-weighted index comprised of securities D，E，F:
What is the price return of this index?
选项：
A. –4.6%.
B. –8.7%.
C. –9.3%.
解释：
B is correct.
The price-weighted index's price return is the percentage change in the index's price:.
考点：价格加权指数计算price return
这道题原解析已经很清晰了，只要注意我们这里计算的是price return，所以不需要考虑期间收益。
price weigh 不是等于股价相机除以股票个数？

请问 这道题与NO.PZ2015122801000011有何不同， 做法为什么不同？
