Using this graph, the implied volatility shows how far the stock price could change over one "standard deviation," which usually equals 68 percent.For example, a $10 stock with a 20 percent In finance, volatility (symbol σ) is the degree of variation of a trading price series over time, usually measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Variance is a measure of the dispersion and is not bound by any time period. On the other hand, volatility captures the degree of variation of a time series over time. In finance, volatility is a measure of the standard deviation over a certain time horizon (typically annual). How to Calculate Annualized Volatility. Putting market volatility into annual terms. A stock's volatility is the variation in its price over a period of time. For example, one stock may have a tendency to swing wildly higher and lower, while another stock may move in much steadier, less turbulent way. Historical vs. implied volatility. There are many different types of volatility, but options traders tend to focus on historical and implied volatilities.

Historical volatility is the annualized standard deviation of past stock price movements. It measures the daily price changes in the stock over the past year. While standard deviation determines the volatility of a fund according to the disparity of its returns over a period of time, beta, another useful statistical measure, compares the volatility (or Volatility is another name given in Finance to the $\sigma$ which appears in the formulas for the GBM. It is the standard deviation of the logarithmic stock price changes. It is also the standard deviation of the underlying BM, but to find the stock price we then have to take the Exponential of this BM, giving a point on the GBM. However, volatility does not take into account whether the stock's price has gone up or down. When calculating standard deviation, a 10 percent gain and a 10 percent loss are exactly the same. Therefore, you should never select a stock on the basis of its volatility alone.
