If the fund loses money, the probability of holding it back for a long time depends on many factors, such as fund type, investment strategy, market environment and so on. We can't simply conclude that long-term holding will definitely return to the original.

1. Equity fund: If the fund invests in stocks, the market may fluctuate greatly, and there may be little chance of returning its capital in the short term. But if it is held for a long time, the market may return to rationality and have the opportunity to return to its original value.

2. Bond fund: If the fund invests in bonds, then relatively speaking, the market fluctuation may be smaller, and the chances of holding funds for a long time may be greater.

3. Hybrid funds: The opportunity for hybrid funds to return capital depends on the proportion of stocks and bonds in their portfolios and the investment strategy of fund managers.

Generally speaking, if the investment strategy of the fund is reasonable and the fund manager is experienced, the chances of holding the fund for a long time may be greater. However, whether it is short-term investment or long-term investment, there is no guarantee that it will be able to return to the capital. Investment is risky, and investors need to make investment decisions according to their own risk tolerance.
