有点搞不清何时开根号,波动率和风险特指standard deviation(开根)还是variance(不开根)?

同学,你好: Volatility is defined here as standard deviation, where σΔE/E, σΔA/A, and σΔL /L represent the standard deviations of the percentage changes in market value of equity capital, asset holdings, and liability claims, respectively.波动率在这里定义为标准差。σΔE/E, σΔA/A, and σΔL /L代表的是权益、资产、负债的标准差。
学习辛苦了,继续加油,你会做的更好哟!
