Yes, but it's very risky. Buying a fund at a high level means that the higher the cost of the fund, the higher the cost, the greater the risk that investors take, the smaller the probability of gaining and the greater the probability of losing. It is better to buy funds at a low level. If you want to buy a fund at a high level, you can choose a fixed investment method.

The fund mainly invests in a basket of stocks, and the risks and returns are determined by this basket of stocks. Invested stocks go up, funds go up, invested stocks go down and funds go down.
