How do you find the standard deviation of an option?
The standard deviation of a particular stock can be quantified by examining the implied volatility of the stock’s options. The implied volatility of a stock is synonymous with a one standard deviation range in that stock. It’s important to note these values are just for one side.
What is standard deviation indicator?
The standard deviation indicator. Standard deviation is an indicator that measures the size of recent price moves of an asset, to predict how volatile the price may be in future. It can help you decide whether the volatility of the price is likely to increase or decrease.

What does deviation mean?
In mathematics and statistics, deviation is a measure of difference between the observed value of a variable and some other value, often that variable’s mean. The sign of the deviation reports the direction of that difference (the deviation is positive when the observed value exceeds the reference value).

- Divide this sum by the number of observations.
How do I work out standard deviation in Excel?
The population standard deviation is calculated using =STDEV(VALUES) and in this case the command is =STDEV(A2:A6) which produces an answer of 0.55. The sample standard deviation will always be greater than the population standard deviation when they are calculated for the same dataset.
How do you interpret the standard deviation?
More precisely, it is a measure of the average distance between the values of the data in the set and the mean. A low standard deviation indicates that the data points tend to be very close to the mean; a high standard deviation indicates that the data points are spread out over a large range of values.
