The essence of a fund is to help investors who want to invest but are not professional to manage their assets, so investors can stay away from the fund for a long time after buying it.

But this does not mean that you can ignore it. If you invest in a currency fund, you can not look at it for a long time. But if you invest in a stock fund, you need to look at it at intervals. At this time, investors need to care about whether the market conditions exist.

Risk, if there is risk, you should sell the fund as soon as possible.
