Volatility refers to the amount of uncertainty or risk about the size of changes in a security’s value. A higher volatility means that a security’s value can potentially be spread out over a larger range of values. This means that the price of the security can change dramatically over a short time period in either direction. A lower volatility means that a security’s value does not fluctuate dramatically, but changes in value at a steady pace over a period of time.
One measure of the relative volatility of a particular stock to the market is its beta. A beta approximates the overall volatility of a security’s returns against the returns of a relevant benchmark (usually the S&P 500 is used).
Volatility is measured by the Chicago Board of Options Exchange (CBOE), primarily through the CBOE Volatility Index (VIX) and, to a lesser extent, the CBOE Nasdaq Volatility Index (VXN) for technology stocks. The VIX tracks the speed of stocks’ price movements in the S&P 100; the VXN tracks it in Nasdaq 100 stocks. Both indices take a weighted average of the estimated volatility of eight stocks on a particular index. Both are calculated every 60 seconds over the CBOE’s trading day, which means it records a great deal of fluctuation.
