This chart shows Volatility for Marvel Comics, defined to be the price range as a portion of the average price: So, to derive the Daily Volatility on 12/31/2009 of 0.7%, the price range for the day (0.41) was divided by the average price (54.18). 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. Average Daily Volatility over the history of MVL has been 4% in contrast to the Average Quarterly Volatility of 42%. |
