Extremes Trump Tranquility

Summary

  • There are very few truisms in markets, but there are absolute truths.
  • The two most powerful absolute truths? Consistency of strong performance is a lie, and volatility is perhaps the most mean-reverting aspect of market behavior.
  • Anyone who tells you that they can achieve consistent outperformance (or performance period) has absolutely zero understanding of markets. None.

"All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident." - Arthur Schopenhauer

The degree to which misinformation is spread and believed is remarkable, a theme I expressed in last week's writing. But what is even more incredible is the extent to which people fall for small sample and recency bias. The very immediate short-term past is extrapolated to the long-term future in a way that really needs to give everybody pause. Investment decisions are based off of one-liners and one-direction, void of any serious analysis about where we are, where we've been, and where we have no clue we are heading.

Consistency of strong performance is a lie, and volatility is perhaps the most mean-reverting aspect of market behavior. Let me put it simply. Anyone who tells you that they can achieve consistent outperformance (or performance period) has absolutely zero understanding of markets. None.

Removing the 10 worst days results in even stronger performance than one might imagine.

As far as the cumulative return of the "incredibly consistent strong" US market, buy and hold since the March 9,2009 low in the S&P 500 SPDR ETF (SPY) is 310.36%. That return
