Whether you should sell the fund after losing more than 300 depends on your personal wishes.

The market's weakness has been determined. It will not rebound tomorrow just because it broke 5,000 today. On the contrary, there will be a further decline process. The next support is around 4,800 points, and it is expected to repeat between 4,500 and 5,000. Oscillation builds a bottom. There will be a process, and it will definitely not rebound immediately.

To be fair, whether to redeem or not depends on individual circumstances and is not a general rule. In theory, funds are long-term investments, so you don’t have to worry about fluctuations during the period. However, given that many people currently do not follow the principle of investment funds at the beginning and buy them with money that they will not use for a period of time, but invest as much as they have. In this case, it is more difficult to maintain a normal mind and face the fund's losses with a better attitude.
