These all need to be judged according to the data. For example, we can compare the past interval data of 28 Shenwan first-class industry indexes to roughly judge which industries a certain interval market prefers, which corresponds to the above-mentioned comprehensive style of fund managers, so as to judge whether the two styles fit.
Based on the understanding of the investment logic and industry preference of fund managers, coupled with the analysis and judgment of the past market (with what), we can make a general judgment on whether the investment logic and style of the selected fund managers conform to this market; Whether the active management of the fund has helped us obtain a certain excess return, and so on.
However, we can't rely entirely on the industry to screen funds. Many fund managers choose stocks from the bottom up. They pay more attention to the strength and future growth of the enterprise itself and look for "excellent potential enterprises in each industry" to win the return on investment. For example, although the medical biological index seems to be launched only in August, outstanding leading pharmaceutical companies keep hitting new highs, and the corresponding performance of actively managing pharmaceutical funds is also very eye-catching.
Finally: the correct way for ordinary investors to invest in funds.
Make a comprehensive investigation on the performance, fluctuation and investment style of fund managers, and try to choose the products of fund managers with excellent long-term performance and stable style, because such funds are more likely to perform well in the future.
If a fund has been losing money, we must first find out the comprehensive strength of this fund, whether it has excellent long-term performance, but the stage does not conform to the market style, or whether there is a gap in its own strength. If it is the former, it is necessary to consider continuing to hold it, giving the fund manager a longer time to create excess returns for investors, and calming his mind to accompany the fund manager through difficult times, because almost no one can perform particularly well at any time; If it is the latter, it is necessary to stop loss in time and admit that your investment mistakes are no big deal. There are many opportunities to make a comeback in the future, and the winner is the one who laughs last.
