Historical volatility is a measure of past performance. Because it allows for a more long-term assessment of risk, historical volatility is widely used by analysts and traders in the creation of investing strategies.
To calculate the volatility of a given security in Microsoft Excel, first determine the time frame for which the metric will be computed.
A day period is used for this example. Next, enter all the closing stock prices for that period into cells B2 through B12 in sequential order, with the newest price at the bottom. Note that you will need the data for 11 days to compute the returns for a day period.
In column C, calculate the interday returns by dividing each price by the closing price of the day before and subtracting one. Volatility is inherently related to standard deviationor the degree to which prices differ from their mean.
S C3:C12 " to compute the standard deviation for the period. As mentioned above, volatility and deviation are closely linked. This is evident in the types of technical indicators that investors use to chart a stock's volatility, such as Bollinger Bands, which are based on a stock's standard deviation and the simple moving average SMA.
However, historical volatility is an annualized figure, so to convert the daily standard deviation calculated above into a usable metric, it must be multiplied by an annualization factor based on the period used.
How to Calculate Volatility in Excel?
The annualization factor is the square root of however many periods exist in a year. The example above used daily closing prices, and there are trading days per year, on average. Volatility in a stock has a bad connotation, but many traders and investors seek out higher volatility investments in order to make higher profits.

Step 1: Firstly, gather daily stock price and then determine the mean of the stock price. Let us assume the daily stock price on an i th day as P i and the mean price as P av.
Step 3: Next, compute the square of all the deviations i. Step 4: Next, find the summation of all the squared deviations i. Step 5 : Next, divide the summation of all the squared deviations by the number of daily stock prices, say n. This is called the variance of the stock price. Step 6: Next, compute the daily volatility or standard deviation by calculating the square root of the variance of the stock.
