If you buy a fund and buy the top of the mountain, investors need to know whether the fund they buy is a long-term investment or a short-term investment. If it is a long-term investment, then it must be very optimistic about the fund in the long term. Then the next step What you have to do is to keep adding positions to bring down the low price.
