Fastenal Company Historical Volatility

FAST:  Daily Volatility = Price Range as a percent of the daily average price.

Volatility is defined as the price range for a period, divided by the average price for the period:

For instance, on 2/18/2011 the average price was 63.24 with a range of 1.01, indicating a Daily Volatility of 1.5%. The Daily Volatility is obtained by dividing the daily range by the daily average. A longer Volatility period such as Weekly Volatility is obtained by dividing the weekly price range by the weekly mean 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 21 years, the Average Quarterly Volatility of FAST stock price has been 29% while the Average Daily Volatility has been 3%.

FAST:  Volatility Curve

If you have ever seen a "yield curve" you should be able to understand the concept behind this "yield curve". These Volatility Curves each apply to a discrete time interval. 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.
