Volatility is defined as the price range for a period, divided by the average price for the period: For instance, on 7/28/2010 the average price was 7.24 with a range of 0.25, indicating a Daily Volatility of 3.4%. Daily Volatility (the daily range as a portion of the daily average price) is plotted in green. Blue is Weekly Volatility, which is the weekly range as a portion of the weekly average price. It is important to avoid confusing this with the weekly average of the daily volatility, which is a completely different concept. The red plot shows the actual price. Volatility, as measured through various intervals, ( Daily, Weekly, Monthly and Quarterly) is plotted according to color. Investors often make a distinction between the concept of Volatility, and the concept of Risk. Academics define them to be exactly equivalent, but as can be seen here, there is good reason to distinguish between the levels of volatility or risk experienced across different time frames. During 20 years, the Average Quarterly Volatility of RF stock price has been 24% while the Average Daily Volatility has been 3%. |

If you have ever seen a "yield curve" you should be able to understand the concept behind this "yield curve". Each Volatility Curve is a snapshot in time. From left to right, each position plots the Volatility associated with increasing intervals of time. However, as seen in this plot of the RF Volatility Curve, the increase is not constant. |
