学员你好,题目问的是每一个选项的情况。
B中The return for the perfect timer in each year is the average of the return on stocks and the return on bills. 应该是两者取其高,因为完美的则时就是神算子,哪一个表现好就投哪一个,还很准。
C中Market timing involves shifting funds between a market-index portfolio and a safe asset, depending on whether the market index is expected to outperform the safe asset.这个就是择时能力的定义啦。
