The buying skills are as follows:

1. Wide base VS narrow base

Generally, stock indexes can be divided into wide base and narrow base. SSE 5, CSI 3, CSI 5 and GEM are broad-based. These indexes have a wide investment range and are distributed in different industries and themes. As long as the market conditions come, they will perform well and are suitable for most investors. Consumption, medicine, dividends, computers and other indexes belong to a narrow base. These indexes have a narrow investment scope and concentrated risks, and are suitable for investors who have a certain understanding of a certain industry or theme and have an accurate grasp of the market (if investing, it is recommended to pay more attention to industries and themes with medium and long-term investment logic).

2, "risk" matching

Because the underlying index generally has a long history to trace, the risk of index funds can be predicted to some extent. For example, the constituent stocks of SSE 5 and CSI 3 Index are large-cap stocks and value-oriented with low historical volatility; The constituent stocks of CSI 5 and Growth Enterprise Market are small and medium-sized stocks, with a high historical volatility. Investors should also match their own risk preferences when choosing the underlying index.

3. Fit the market style

The selected index must fit the current market style. Otherwise, if the market differentiation is serious, it will not only make no money, but also lose money. As can be seen from the Sharp ratio in the above table, in recent years, large-cap stocks have performed well and small and medium-sized enterprises that were "brilliant" in the past have suffered miserably. At present, the market style continues. As of October 29, 218, the SSE 5 has fallen by 16.46% and the CSI 5 has fallen by 33.41% this year.

4. Low stock valuation

Valuation is also an important criterion to judge whether the index is worth investing. Whether it is a wide base or a narrow base, we should try our best to choose an underestimated one. On the one hand, low valuation represents a higher margin of safety, and there is limited room for further decline; On the other hand, when the index is extremely undervalued, profit-seeking funds will enter, and the valuation will return to a reasonable level in the long run. Generally speaking, the historical percentile of PE and PB is below 3%, which is underestimated. In addition to PE and PB, ROE is also a frequently referenced indicator. At present, the information of CSI 5, GEM index, all-index optional, all-index medicine and all-index is extremely underestimated (percentile <: 1%); From the perspective of ROE, CSI 5 is poor and its profitability is not good.
