First of all: be sure to choose the right product. The skill of choosing fund products is "the combination of high (medium) and low-risk products". For high-risk fund products, we can consider index funds with large fluctuations and close to the index trend, such as Huaan China A-share enhancement index, and the redemption fee is 0. For low-risk fund products, we can consider low-risk money funds and bond funds, such as Huaan Cash Fuli Currency, Huaan Stable Income Bond A/B, Huaan Enhanced Income Bond A/B ... Second, make sure to choose the right index. The trick to choose the target index is to "choose the corresponding index according to the high-risk products". If there is no correlation between the underlying index and the high-risk fund products invested by investors, then this judgment of the trend is meaningless. Therefore, when choosing the underlying index, it is not to see which index has the highest increase, but to choose the index with high correlation with high-risk fund products. For example, if the high-risk fund product set by the trend investment is "Huaan China A-share enhancement index", then the target index that investors can set should be "CSI 300". Once again, we must choose the correct moving average. The secret of choosing a combination of moving averages is "short-term moving averages"
