MSFT Stock 200-Day Standard Deviation: Calculation & Formula

To calculate the 200-day standard deviation price for MSFT stock, you can use the following formula:

1. First, calculate the mean price over the past 200 days:

   Mean = (Price1 + Price2 + ... + Price200) / 200

2. Next, calculate the deviation of each price from the mean:

   Deviation = Price - Mean

3. Square each deviation:

   Squared Deviation = Deviation^2

4. Sum all the squared deviations:

   Sum of Squared Deviations = Squared Deviation1 + Squared Deviation2 + ... + Squared Deviation200

5. Divide the sum of squared deviations by the number of observations (in this case, 200) minus 1:

   Variance = Sum of Squared Deviations / (200 - 1)

6. Take the square root of the variance to get the standard deviation:

   Standard Deviation = sqrt(Variance)

Using historical data for MSFT stock, you can plug in the values for the past 200 days and calculate the standard deviation price.
