Daily Volatility = Price Range as a percent of the daily average price. of Schering-Plough Corporation

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

For instance, on 6/30/2009 the average price was 24.93 with a range of 0.45, indicating a Daily Volatility of 1.8%. 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. The remaining marks on the plot correspond to the Volatility measured across several time intervals.

According to academic theory, Volatility is exactly equal to Risk. But investors often make a distinction between these two concepts. The different character of Volatility as seen in different time frames, lends some support to the investor's view. During 26 years, the Average Quarterly Volatility of SGP stock price has been 22% while the Average Daily Volatility has been 3%.

From left to right, each position plots the Volatility associated with increasing intervals of time. The relationship between the length of time, and the expected change in price, is not linear, as is demonstrated by this chart.
