The point of this brief analysis is that price volatility is a feature of our economic system, not a bug. Since the S&P 500’s creation in 1928, the market has experienced an average of 17 days per year in which the index moved by 2% or more in a single trading CBOE Volatility Index (VIX) session.

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. The index has risen above 35 on six separate of Silver Blaze,” there are plenty of dogs that are not barking occasions over this period, corresponding to pronounced mar- in this graph of market volatility.

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

The good this graph at all. It is human nature to want our effects to have news is that once the system shifts it is in a much more resilient causes, and in retrospect it is easy to assign blame for spikes in state.

The reality is that market moves often have makes the system healthier for a period of time. more to say about the internal state of the market than about external influences. Let us return once again to history as both a guide to and justifi- cation of this analogy. The VIX has risen above 35 only 12 times Consider the following analogy.

As the nearby table illustrates, equity prices often remain emerge. At some point, one additional grain of sand, however, under pressure for a few weeks following the spike in volatility. would cause the whole pile to shift. We would stop and wonder One month out, the market remained in negative territory in why the pile shifted, and as tempting as it would be to blame half of our historical examples, for an average return of -0.7%. the last grain of sand that we dropped, the last grain was no Further out, however, returns have historically improved, so different from all the grains that had come before.
