Then, it may be a high-risk equity fund. Will it keep falling, or even fall? Probably not. Because the rise and fall of stock funds has a great relationship with the stock market, and even depends on the rise and fall of the stock market, and the stock market has never only fallen but not risen.
Of course, for a falling stock fund, whether it can recover when the stock market picks up depends on whether it can persist until the market picks up. When the market is depressed, the number of funds that cannot insist on closing their positions will also increase. But even if the fund is liquidated due to continuous decline, its net value will not decline, more or less.
Therefore, for a falling fund, as long as there is no risk of liquidation, you can always hold it and don't need to sell it.
