What is a Beta Release?

Beta, is now generally considered to mean "test". In a broad sense, there are three traditional names for testing: Alpha (, Alpha), Beta (, Beta), and Gamma (, Gamma), which are used to identify the stage and scope of the test. Alpha refers to internal testing, which is now referred to as CB, that is, the version tested internally by the development team or the test version of limited user experience. Beta refers to public beta, a beta version that is open to all users. And after making some changes, becoming a release candidate (now called RC-Release Candidate), it is called Gamma.

Is a risk metric refers to a systematic risk indicator (Beta coefficient)

Definition : It is a measure of the degree of influence of changes in the market on changes in stock or portfolio returns. Is the sensitivity of the stock or portfolio to the market (systemic risk).

Indicator meaning

The larger, the greater the systemic risk of the fund. According to the CAPM model, Beta is equal to 1, which means that the fund and the market have the same systemic risk, that is, the market rate of return changes x, and the fund's rate of return changes x. Beta is greater than 1, which means that the systemic risk of the fund is greater than the market, that is, the market rate of return changes x, and the fund's rate of return changes greater than x. Beta is less than 1, which means that the fund has less systemic risk than the market, that is, the market rate of change x, and the fund's rate of change less than x.

Popular explanation : It reflects the performance of an investment object relative to the broader market. The larger the absolute value, the larger the change in the return relative to the broader market; the smaller the absolute value, the smaller the change in the return relative to the broader market. If it is negative, it shows that the direction of its change is opposite to that of the broader market; when the broad market is up, it falls, and when the broad market is down, it rises.

According to investment theory, the coefficient of the entire market itself is 1, and if the fluctuation of the net value of the fund's investment portfolio is greater than the fluctuation range of the entire market, the coefficient is greater than 1. Conversely, if the fluctuation of the fund's net investment portfolio is less than the fluctuation of the entire market, the coefficient will be less than 1. Securities with a larger coefficient are usually more speculative securities. Taking the United States as an example, the S & P 500 Enterprise Index (S & P 500) is usually used to represent the stock market, and the beta is 1. If the beta of a mutual fund is 1.10, it means that its volatility is 1.10 times that of the stock market, that is, it is 10% better than the market when it is rising, and 10% worse when it is falling.

Beta is a relative indicator that measures the overall volatility of stock returns relative to benchmark returns for performance evaluation. The higher , the greater the volatility of the stock relative to the performance evaluation benchmark. is greater than 1, the volatility of the stock is greater than the volatility of the performance evaluation benchmark. vice versa.

Index evaluation

Beta only considers the system risk of the fund, while the standard deviation comprehensively describes the entire risk of the fund. Beta is suitable for describing the systemic risk of a fully decentralized fund.

An index describing the degree of change in the price of a stock compared to the overall CSI 300 index.
