1. Earn profits: The fund market has ups and downs. When investors hold the fund for a long time without selling it, there is a probability of profit. It is meaningful to hold the fund for a long time, and the probability of long-term profit is relatively large. Fund investment is mainly to earn the bid-ask price difference. If the fund price rises, it will gain income. As long as the fund price rises, it will gain income.

2. Loss: There is a cycle of fund ups and downs, and the fund may continue to fall for a period of time, which may lead to losses for investors. Moreover, if the fund holds the fund for a long time, it may turn losses into profits not only in the case of profit.

3. Fund liquidation: When the poor performance of the fund triggers the liquidation conditions, the fund will be liquidated. If investors hold it for a long time and don't sell it, investors will bear relatively large losses after the liquidation of the fund.

How to operate after investors buy funds;

1. Long-term holding: It is meaningful to hold the fund for a long time. Investment funds have a higher probability of exchanging time for income. Funds mainly invest in the stock market, and the stock market is short of bulls and bears, so it is more likely to gain income from long-term holding.

2. Make up positions: When investors buy funds and lose money, they can reduce costs by adding positions. The lower the cost, the lower the risk that investors bear, and the greater the probability of returning to capital or generating income in the future.

3. Take profit: After investors buy a fund, they should take profit in time, because the ups and downs of the fund are cyclical, and the fund can't keep rising, so if investors make a profit, or the fund reaches the expected return of investors, they can take profit. Take profit can guarantee investors' income, and it is also a disguised stop loss. Investors can profit from the valuation and the trend of fund themes.

4. Stop loss: The continuous decline of the fund may trigger the risk of liquidation. Therefore, when the loss of the fund is relatively large, investors are worried that the fund will continue to fall and bring more losses, so they can choose stop loss.
