WebbAnnualized Standard Deviation = Standard Deviation of Daily Returns * Square Root (250) Here, we assumed that there were 250 trading days in the year. Depending on weekends and public holidays, this number will vary between 250 and 260. So, if standard deviation of daily returns were 2%, the annualized volatility will be = 2% * Sqrt (250) = 31.6%. WebbAdjusted mean squares are calculated by dividing the adjusted sum of squares by the degrees of freedom. The adjusted sum of squares does not depend on the order the factors are entered into the model.
