Ninety-five percent of data values will fall within two standard deviations (2 x 2.87 in our example), and 99.7% of all values will fall within three standard deviations (3 x 2.87). In this case, the values of $1 to $10 are not randomly distributed on a bell curve; rather. Despite this limitation, traders frequently use standard deviation, as price returns data sets often resemble more of a normal distribution than in the given example. Volatility is a statistic that measures the differences between returns of an investment over a given time period – a greater difference means greater volatility. Generally, the higher the volatility, the more risky an investment is considered to be.

In statistics, heteroskedasticity happens when the standard deviations of a variable, monitored over a specific amount of time, are nonconstant. The standard deviation is a statistic measuring the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.

In the below example of the spot gold marker on the XAUUSD pair, the Average True Range indicator shows a spike during periods of increased volatility.
In finance, volatility (usually denoted by σ) is the degree of variation of a trading price series over time, usually measured by the standard deviation of logarithmic returns. Unlike historical volatility, implied volatility comes from the price of an option itself and represents volatility expectations for the future. Because it is implied, traders cannot use past performance as an indicator of future performance. Instead, they have to estimate the potential of the option in the market.
Alternative measures of volatility
A common method of calculating the relative volatility of a security to the market is its beta. A beta determines the volatility of a security’s returns against the returns of a benchmark (typically an index such as the the S&P 500). Volatility profiles based on trailing-three-year calculations of the standard deviation of service investment returns. The amount and frequency with which an investment fluctuates in value.
What is the difference between risk and volatility?

For individual stocks, volatility is often encapsulated in a metric called beta. Beta measures a stock’s historical volatility relative to the S&P 500 index. Shares of ablue-chip company may not make very big price swings, while shares of a high-flying tech stock may do so often.
The number itself isn’t terribly important, and the actual calculation of the VIX is quite complex. The market uses implied volatilities to gauge the volatility of individual assets relative to the market. Volatility levels are not constant, and fluctuate with the overall level of the market, as well as for stock-specific factors. The price of an at-the-money option will exhibit greater sensitivity to volatility than the price of a deeply in- or out-of-the-money option. Therefore market makers will take a combination of volatility values when assessing the volatility of a particular asset.

How Do You Calculate the Standard Deviation of a Stocks Price?
In other words, you can sell an option, if you feel that it will be less volatile in the future so that you can make a profit when you sell it. The more common way volatility is referred to in finance, is describing the degree of variance in an asset’s traded price within a specific timeframe. This version of volatility in investment is typically measured by the standard deviation of logarithmic returns.
Likewise, low volatility represents little movement in a security’s price over time. Volatility is the most critical factor in financial markets fueling all price action and, therefore, profits.
