A Long-Term View On…Volatility

Volatility: A statistical measure of the dispersion of returns for a given security or market index. Volatility can either be measured by using the standard deviation or variance between returns from that same security or market index.

The words, bad, loss and fear do not show up in this definition from Investopedia. So why is the Volatility Index (VIX) referred to as the Fear Gauge? And what are you supposed to be afraid of anyway?

The daily chart of the VIX for 2012 below shows it traded in a tight range between 13.30 and 27.73. Sure it looks like a monster spike in May but remember that as a statistically derived gauge it cannot go below 0 and is difficult to get below 10, but can rise infinitely. From that perspective 13.30-27.75 is a very low range. And as my friend Adam Warner has pointed out many times this year, it has been overstating the volatility of the market. There has been no fear in the Fear Index in 2012. A closer look at this chart does identify some interesting information, though.
