hello, are you asking what the beta and alpha knots are? Beta and alpha are two forms of income brought about by market changes. Beta describes a risk that fluctuates with the fluctuation of the overall market, which can be called systemic risk. The bigger the Beta, the higher the risk. The characteristics of this kind of risk are: you have me and everyone has it, such as policy risk, geopolitical risk and so on. However, the income from the alpha card mainly depends on the stock selection ability of the fund manager himself and his team.
