The point of this brief analysis is that price volatility is a feature of our economic system, not a bug.

The VIX does precisely this for the overall equity market. It is, however, intellectually spurious to assign cause and effect to these volatility surges, although the labels on our graph do The nearby graph shows the VIX for the past 15 years and precisely that. In the same way that Sherlock Holmes found reveals that the Christmas Eve spike in volatility, while rare, curious evidence in the dog that did not bark in “The Adventure is not unique.

These “dogs that do not bark” should prompt us to exercise caution when assigning cause to market action.
