The signal at the bottom of the fund indicates that the fund has bottomed out, and the signal at the bottom of the fund indicates that it can be bought.

Fund investment also follows the investment logic of buying low and selling high. Buying low and selling high need to distinguish whether the current position of the fund market is low or bottom. There are two ways to distinguish: one is to judge by the theory of technical analysis of reasons, and the other is to judge whether the fund is undervalued by the method of fund valuation.
