The stock market has been in a selling mood for the last two weeks and the bears are predicting more of a selloff. The VIX indicator of market volatility is roaming in the low 20s which is higher than the teens where the CBOE volatility indicator resides during periods of no market turmoil. As market falls it would appear that many investors have decided to take a little profit while others are buying in expectation of a rebound. The question is if this is the start of a long term slide, a more substantial market correction, or just a bump in the road to high stock prices. Simply looking at the elevated VIX the question is this. When investments are volatile should you sell or buy? VIX as a Measure of Volatility What is the VIX and is it important to your investing? Investopedia explains VIX. Created by the Chicago Board Options Exchange (CBOE), the Volatility Index, or VIX, is a real-time market index that represents the market’s expectation of 30-day forward-looking volatility. Derived from the price inputs of the S&P 500 index options, it provides a measure of market risk and investors’ sentiments. It is also known by other names like “Fear Gauge” or “Fear Index.” Investors, research analysts and portfolio managers look to VIX values as a way to measure market risk, fear and stress before they take investment decisions. When the market is going up or staying the same, the VIX is low. When the market is falling the VIX goes up. As an example, at the end of 2008 the VIX went from a normal of 18 up to 81 over a couple of months as the market crashed. The calculation for the VIX is complicated but what it is looking at is puts versus calls as a guide to investor concern.
