The primary consideration is not the temporary rise of the fund, but the long-term profitability of the fund. For example, the CSI index of China Merchants Liquor is rising, and it will fall after a while. What's the point?

Even if you rose at that time, your money could not be cashed, so it was useless. Your fund will not only deduct your management fee, but you can't withdraw it at that time. After the rise, it fell again, and it returned to before liberation.
