After comparing the change of position weight and analyzing the reasons for the change, four representative high-quality stocks are established. Corresponding to four hybrid large enterprises. Finally, according to the stability of the overall return and risk of the industry, it is concluded that investors in the new energy industry should regularly review the investment profit and loss, and appropriately incorporate traditional energy into the asset portfolio for risk hedging.
