In The VIX is Asymmetric, making its derivatives an interesting hedge I explained how the CBOE Volatility Index (VIX) tends to react with sharper and with greater magnitude than stock indexes. There is an asymmetric relationship between stock index returns and the VIX. Below includes yesterdays action when the S&P 500 stock index was down 2% and the CBOE Volatility Index (VIX) spot gained 27%. The chart is a good visual of how, when the stock index falls, implied volatility spikes up.
I have been sharing some observations about the VIX recently because it had gotten do a low level not seen in many years. It’s an indication that investors have become complacent about risk. When a trend gets to an extreme, it’s interesting to observe how it all plays out.
