Should the fund buy or redeem when it falls sharply?
If it is in a bear market, the fund market has been in a downturn, and most funds are in a downturn. If investors have sufficient funds and are optimistic about the fund, they can buy when the fund falls, which can buy more shares at a lower price, but it also increases the risk. If the fund continues to fall, it will suffer heavy losses.
If the fund itself is not good, other funds are still falling when they are rising, and the performance of the fund has been poor, then you can consider redeeming the stop loss of the fund, but the lost money is wasted.
Can I buy the fund when it falls sharply?
You can buy when the fund plummets, but it depends on the situation of the fund. If the fund purchased by investors is adjusted, the price is adjusted and the net value of the fund falls, then you can choose to wait for the adjustment of the investment target of the fund and the net value of the fund will rise.
If it is because the fund manager of the investment fund is inexperienced and the performance of the managed fund is relatively poor, then don't consider buying it. It is very likely that the fund has fallen again, so the fund is likely to lose more and more.
