To buy a fund, we must first roughly judge the market sentiment and the direction of the industry boom, and then look at the historical position of the current market index. If there is an industry index valuation table, you can avoid high valuation industries.

Secondly, you should choose the right fund and give priority to the fund with excellent long-term performance managed by well-known excellent fund managers. During the fund management period, the net exit control is good, and the fund can be pulled back even if it encounters systemic risks.

Furthermore, think in the opposite direction. Outside the hot plate, we should pay attention to the non-hot plate, and have the consciousness of layout in advance, so as to avoid the mistakes of "waiting for the rabbit" and "carving a boat for a sword" without understanding its internal characteristics.
