BETA (β) value is a risk index, which is used to measure the price fluctuations of individual stocks or mutual funds relative to the entire stock market. The higher the β value, the greater the volatility of the stock phase on the performance evaluation benchmark, and vice versa. When β = 1, it means that the income and risks of the stock are consistent with the income and risks of the broader market; when β> 1, it means that the stock income and risk are greater than the income and risk of the broader market index. Our Beta calculation method is the same as finance.yahoo.com, markets.ft.com, zacks.com and cnbc.com . Default Beta setting is data over a 5 Years (Monthly) period and base value of 1.0 is S&P 500 Index.
