3.5.1 Volatility Overview

This page is meant to show the volatility of an underlying security/index. Volatility is a measure of how much and how quickly the underlying price moves over a specific time frame. This information can either be used for anticipating future moves in the underlying, implied volatility (IV). Or it can be used to measure the range of return of an underlying from the past, historic volatility (HV). Both metrics are expressed in percentage rate of change. The key difference is that IV measure equity price variability presented by options pricing, whereas HV is an n-day annualized standard deviation of price changes. It is important to note that a high HV does not imply a high IV and vice versa. The two are independent of one another. The information displayed on this page is meant to inform you of potential volatility, and be able to compare it to historical volatility of the same ticker.
