If investors are in a state of loss, then the fund's plunge is a better operation mode, which will reduce costs. When the fund falls, the same fund buys more fund shares, thus sharing the cost of investors equally. The lower the cost, the lower the risk that investors bear, and the higher the probability of recovering capital or gaining income in the future.

If the investor is in a profitable state, then the fund can continue to hold the fund without operation. If investors judge that the market outlook is poor, they can redeem the fund.

Is it right to buy funds on the day of the market crash?

When the market falls, stock funds and index funds may also fall under the influence of the market. If the market crash is a short-term correction, investors can take the opportunity to buy some stock funds and index funds at a low level and wait for the market to rebound. If the market will continue to decline in the later period, it is not appropriate for short-term investors to buy stock funds and index funds at this time. For long-term investors, they can take the opportunity to open positions in batches, share costs, spread risks and wait for opportunities to rise by constantly adding positions during the decline.

Of course, in the process of market decline, investors can also choose to sell stocks and buy some bond funds or money funds with less risk and stable income to avoid the risks brought by market decline.

It should be noted that investors should also consider the historical performance of the fund, the management ability of the fund manager and the investment direction of the fund when purchasing the fund.
