For investors it represents an important measure of how desirable it is to own a certain stock, based on the investor's appetite for risk and reward.

Determine a period in which to measure returns, volatility forex cal. The period is the timeframe in which your stock price varies. This can be daily, monthly, or even yearly. However, daily periods are most commonly used. Choose a number of periods. The number of periods, n, represents how many periods you will be measuring within your calculation. If you are calculating daily periods, a common number of periods is 21, the average number of trading days in a month.
A smaller value would not give you very good results. In fact, volatility forex cal, the larger the value, the smoother your result becomes. You can also use 63 periods to represent the number of trading days in three months or periods to represent the average number of trading days in a year.
Volatility forex cal closing price information. The prices you will use to calculate volatility forex cal are the closing prices of the stock at the ends of your chosen periods. For example, for daily periods these would be the closing price on that day. Market data can be found, and in some cases downloaded, from market-tracking websites like Yahoo!
Finance and MarketWatch. Calculate returns. Volatility forex cal return of a stock in a given period can be defined as the natural log, ln, of the closing price of a stock at the end of the period divided by the closing price of the stock at the end of the previous period. On many calculators, the natural log key is simply "ln" and must be pressed after the rest of the equation has already been calculated.
Pressing the ln key to solve gives a result of about 0. The natural log is used to convert the numerical change in value of the stock over the period to an approximation of the percent change between days. Part 2 of Find the mean return. Take all of your calculated returns and add them together. Then, divide by the number of returns you are using, n, to find the mean return. This represents the average return over the time period you are measuring. For example, imagine that you had 5 periods that had calculated returns of 0.
You would add these together to get 0. Therefore, your mean, volatility forex cal, m, would be 0. Calculate the deviations from the mean. For every return, Rn, a deviation, Dn, from the mean return, m, can be found. Complete this calculation for all returns within the range you are measuring.
Using the previous example, you would subtract your mean, 0. Find the variance. Your next step is to find the mean variance of the returns by summing the squared individual deviations from the mean of the returns. Again, sum the squares of the deviations, volatility forex cal, Dn, and divide by the total number of variances minus 1, n-1, to get your mean variance.
First, square your deviations from the last step. These would be, in order: 0. Sum these numbers to get 0, volatility forex cal. Then, divide by n-1, which is 4, to get 0. Calculate the volatility. The volatility is calculated as the square root of the variance, S. This "square root" measures the deviation of a set of returns perhaps daily, weekly or monthly returns from their mean.
It is also called the Root Mean Square, volatility forex cal, or RMS, of the deviations from the mean return. It is also called the standard deviation of the returns. In the example, volatility forex cal, this would just be the square root of S, which is 0. This number has been rounded to three decimal places. You may choose to keep more decimals to be more accurate.
A stock whose price varies wildly meaning a wide variation in returns will have a large volatility compared to a stock whose returns have a small variation.
By way of comparison, for money in a bank account with a fixed interest rate, every return equals the mean i, volatility forex cal.
Part 3 of Set up your spreadsheet. Calculating volatility is much simpler and faster in Excel than it is by hand. Start by opening Microsoft Excel on your computer and opening a blank worksheet.
Input market information. The next step is to import the closing prices for the stock you are measuring. Input the closing prices vertically in the A column, with the oldest price first and the most recent price at the bottom. For example, 21 days' worth of prices would go in cells A1-A Calculate interday returns. Interday returns are simply the difference between the closing prices of consecutive days.
The results of this calculation will go in the cells adjacent to the closing prices, in column B. This will calculate the percent changes between day 1 and day 2 of your range.
Then, drag the formula down the rest of your range to the last price.
