β coefficient has no fixed value. Beta coefficient is a statistical concept, which reflects the performance of an investment object relative to the market. The greater its absolute value, the greater the change of its income relative to the broader market; The smaller the absolute value, the smaller the change range relative to the market.

If it is negative, it means that the direction of change is opposite to the market; When the market rises, it will fall, and when the market falls, it will rise. Because we invest in investment funds in order to obtain expert financial services and achieve better performance than passive investment in the broader market, this indicator can be used as an indicator to examine the ability of fund managers to reduce the risk of investment fluctuations.

Summary of β coefficient method;

At present, according to the characteristics and perspectives of research paradigm, there are three main methods of stock investment analysis: basic analysis, technical analysis and evolution analysis. The theoretical basis, premise, hypothesis, research paradigm and application scope of these three analytical methods are different, and they are interrelated and have important differences in practical application.

Among them, basic analysis belongs to general economic paradigm, technical analysis belongs to mathematics or Newton paradigm, and evolutionary analysis belongs to biology or Darwin paradigm; Basic analysis is mainly applied to the selection of investment targets, while technical analysis and evolution analysis are mainly applied to the time and space judgment of specific operations as an important means to improve the effectiveness and reliability of stock investment analysis.
