How to calculate volatility of a stock?
The formula for the volatility of a particular stock can be derived by using the following steps: 1 Firstly, gather daily stock price and then determine the mean of the stock price. Let us assume the daily stock price on an ith day as Pi and the mean price as Pav. 2 Next, compute the difference between each day’s stock price and the mean price, i.e., Pi – P. 3 Next, compute the square of all the deviations, i.e. (Pav – Pi)2. 4 Next, find the summation of all the squared deviations, i.e. ∑ (Pav – Pi)2. 5 Next, divide the summation of all the squared deviations by the number of daily stock prices, say n. It is called the variance of the stock price.#N#Variance = ∑ (Pav – Pi)2 / n 6 Next, compute the daily volatility or standard deviation by calculating the square root of the variance of the stock.#N#Daily volatility = √ (∑ (Pav – Pi)2 / n) 7 Next, the annualized volatility formula is calculated by multiplying the daily volatility by the square root of 252. Here, 252 is the number of trading days in a year.#N#Annualized volatility = = √252 * √ (∑ (Pav – Pi)2 / n)

How to calculate volatility?
The following steps can be followed when calculating volatility through determining the standard deviation over time: 1 Collect the historical prices for the asset. 2 Compute the expected price (mean) of the historical prices. 3 Work out the difference between the average price and each price in the series. 4 Square the differences from the previous step. 5 Determine the sum of the squared differences. 6 Divide the differences by the total number of prices (find variance). 7 Compute the square root of the variance computed in the previous step.
