In theory, investors can make up their positions at any time, but they should also find the right time to make up their positions. If they make up their positions at the beginning of the falling market, it is very uneconomical to make up their positions continuously in the afternoon. Generally speaking, it is only after thinking that there is a signal to stop falling in the market outlook that the position will be covered, otherwise it will always be covered halfway up the mountain.

The method of covering positions is as follows:

1, when the fund makes up its position depends on the overall environment of the stock market: if it is an upward trend, it can make up its position when the fund falls sharply; If it is a descending passage, don't make up the position; If it is a structural market, you can operate in bands. To judge the market trend, we can look at the Shanghai Composite Index or the index corresponding to the fund.

2. Make up the position when the fund has support. On-site funds can directly look at the support level and pressure level of the index, and off-site funds can be judged by the trend of the underlying stocks.

3. When covering positions, you must cover positions when falling. You can make up the position according to the fund valuation. If the valuation of the fund falls sharply, you can buy it before three o'clock. When covering positions, you can cover positions by the same amount. If it falls by 1%, you can make up the position by 1 1,000 yuan.
