In this example I will be calculating historical volatility for Microsoft stock (symbol MSFT), using Yahoo Finance data from 31 August 2015 to 26 August 2016. To calculate σ annual from the weekly numbers, multiply σ weekly, by the square root of 52, as there are 52 weeks in a year. Suppose you found the daily volatility, σ daily, of a particular stock is 1.2 %. Multiply this by the square root of 252, and you get σ annual = 19.05% . When not specified, Knowing this, you can easily convert annual volatility to daily volatility by dividing it by the square root of the number of trading days per year. Assuming 252 trading days per year , which has been the average for US stock and option markets in the last years, you can convert annual implied volatility to daily volatility by dividing it by the square root of 252, or approximately 15.87. Assuming that there are 252 trading days, the volatility can be annualized using the square root rule, as follows: Annualized Volatility = 1-day volatility *Sqrt(252) = 0.78%*Sqrt(252) = 12.38% Note that if we had used weekly data instead of daily data, we will use Sqrt(52) as there are 52 weeks in a year. Historical volatility is the annualized standard deviation of returns. We must multiple the standard deviation by an annualization factor, which is the square root of how ever many of your periods are in a year. This example is daily data; there are 262 trading days in a year,

This example is daily data; there are 262 trading days in a year, Annualized 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%
