A stock fund means that you give money to experts and experts help you buy stocks. Now that the market has fallen into this state, experts will fall at any level. In addition, stock funds must have a high position of more than 80% according to regulations and invest in multiple stocks, so it is unlikely that a bull stock will rise against the market when the market plummets.
The same fund may change the fund manager; The same fund manager may operate well in some periods and not well in some periods; All these will affect the performance of the fund. Not so good. Just say that a fund is good. To measure the quality of stock funds, there needs to be an interval, such as three months. For example, in the past three months, the market has fallen by 10%, and the stock fund you bought has only fallen by 2%, so you bought a good fund; On the contrary, the market rose by 10%, while the fund you bought only rose by 2%. Although it fell by 2% just now, it has risen by 2% now, but in fact, what you are buying now is a very poor fund.
