1. The selected fund is not suitable for fixed investment.

The money raised by the money fund is invested in the money market, and the money raised by the bond fund is invested in the bond market, which leads to their relatively stable trends and small fluctuations. It is difficult for investors to make a smile curve effect and make little money. For those stock funds and index funds with large fluctuations, the fluctuation range is large, and investors are more likely to make a smile curve effect and earn a certain price difference.

2. The timing of intervention is not right.

The wrong timing of intervention will also make it difficult for investors to make money. For example, when the market is not good and the fund is in a downward channel, investors will make fixed investment operations. Although the fixed investment will spread the cost of holding positions equally, it is difficult for investors to make money or even lose more in the short term.
