This chart shows Volatility for Pitney Bowes Inc., defined to be the price range as a portion of the average price: For instance, on 3/11/2010 the average price was 23.24 with a range of 0.73, indicating a Daily Volatility of 3.1%. 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. For reference, the price is plotted in red. 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. Average Daily Volatility over the history of PBI has been 2% in contrast to the Average Quarterly Volatility of 20%. |

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. As the timespan across which Volatility is measured increases, the Volatility is expected to increase. The relationship between the length of time, and the expected change in price, is not linear, as is demonstrated by this chart. |
