## Volatility of a stock standard deviation

Standard deviation is a measure of the dispersion of a set of data from its mean . It is calculated as the square root of variance by determining the variation between each data point relative to 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.e., there's no deviation) and the volatility is 0. Annualizing volatility To present this volatility in annualized terms, we simply need to multiply our daily standard deviation by the square root of 252. This assumes there are 252 trading days in Volatility is determined either by using the standard deviation or beta Beta The beta (β) of an investment security (i.e. a stock) is a measurement of its volatility of returns relative to the entire market. It is used as a measure of risk and is an integral part of the Capital Asset Pricing Model (CAPM). A stock's historical volatility is measured as the standard deviation of its past returns (annualized). In the table below, we list historical volatility (standard deviation) estimates over the past year and past 5 years. Current volatility estimates from our volatility models, and the average volatility forecast over the next month. Standard Deviation. When you say that an investment like a stock market index fund has an expected return of 9%, you're saying that in any year there is a chance that your return will be better than 9% and a chance that it will be worse.

May 7, 2019 Volatility is inherently related to standard deviation, or the degree to on a stock's standard deviation and the simple moving average (SMA).

You can describe and measure volatility of a stock (= how much the stock tends to move) using other statistics, for example daily/weekly/monthly range or average true range. These measures have nothing to do with standard deviation. Standard deviation is only one way of calculating and measuring Standard deviation is a statistical term that measures the amount of variability or dispersion around an average. Standard deviation is also a measure of volatility. Generally speaking, dispersion is the difference between the actual value and the average value. The larger this dispersion or variability is, the higher the standard deviation. Volatility is a statistical measure of the dispersion of returns for a given security or market index . Volatility can either be measured by using the standard deviation or variance between

### I think you are better off looking at the Beta of a stock, which is the standard deviation of the stock times its correlation with the market divided by the standard deviation of the market. [math]\beta=\frac{Cov(R_e,R_p)}{Var(R_p)}=SD(R_e)\frac{

It is also called the Root Mean Square, or RMS, of the deviations from the mean return. It is also called the standard deviation of the returns. [10] X Research One thing we can note is that standard deviation is non-directional and different stocks will have different standard deviations no matter what their price is. The size If stock B also has a volatility of 10% but a price trend of 5%, its one standard deviation return will be between −5% and 15%. Stock with higher volatility will have

Clearly, stock X never deviated from its initial return (Y1), therefore it has a standard deviation of 0. On the other hand, the return of stock Y fluctuated/deviated significantly year after year. This implies a high standard deviation. The greater the volatility of returns, the higher the standard deviation is. - 3 standard deviations encompasses approximately 99.7% of outcomes in a distribution of occurrences 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. 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.
