1. From the historical trend of the fund network,

The trend of fund net profit is in a downward trend for a long time. When the decline rate exceeds 50%, investors can consider that the upside of the fund is greater than the downside, and buy in moderation during the decline. On the contrary, the fund's net profit has been on the rise for a long time, with a large increase. When it is higher than 50%, investors can consider that the upside of the fund is less than the downside.

2. From the perspective of fund performance.

The strong will always be strong and the weak will always be weak, that is, the fund performance is good, the fund manager has strong operational ability, and the fund net profit continues to rise. Investors can consider buying in the process of rising, but the performance of the fund is poor, the operating ability of the fund manager is weak, and the net profit of the fund continues to decline.

3. From the perspective of fund investment objectives.

If the fund investment target is in a bullish trend and has great development prospects and potential, investors can make additional operations, that is, the fund investment target bought in the rising process is in a blank check trend and has poor development potential, so investors should not buy it in the falling process.

No matter whether investors add positions or positions, they should control positions to reduce the losses after investors buy in the wrong direction, or increase the remaining funds for supplementary operations to reduce the cost of positions.
