Some friends followed suit to buy funds, and then the funds plummeted, and everyone was confused. Then why does the same fund make money for others and lose money for itself?
In fact, the point that the fund buys is different. Let's give a simple example: suppose that investor A bought a fund at a low level, sold it at a high level and made money, and showed the proceeds to investor B. Investor B saw this good thing and bought it immediately, but the buying point was at a high level, so it began to lose money after buying and continued to lose money after redemption.
Therefore, when buying a fund, don't buy it blindly. You should read more books about funds, have a general understanding of funds, and then start buying. Secondly, after the fund plummets, you can't bear the risk. You should redeem it in time. Don't hang on and watch the money run away bit by bit.
Secondly, when you buy a fund, you should allocate it reasonably. Don't spend all your money on stock funds. Equity funds are very risky. All investments of equity funds focus on risks, and some other fund types can be configured. For example, the ratio of equity funds to bond funds is 3: 7, so that when the fund falls sharply, you will not lose too much and you can face it calmly.
