Maybe it’s just me but a lot of end-of-year commentary about financial markets in 2016, implicitly and sometimes explicitly, makes it sound as if it was a crazy year. It wasn’t. In fact, it was amazingly normal. This is true of at least the S&P 500 (I’m not going to be more ambitious here) which is what I think many of these commentators are talking about.1,2
Annualized daily volatility during 2016 came in at 13.1%. Based on rolling same-length periods going back to 1929 this falls at the 47th percentile.3 You say you don’t want to compare to the craziness of the Great Depression? Maybe that leads to everything else looking calm and you don’t think that’s meaningful. That’s reasonable. Well, that same value of 13.1% is at the 54th percentile since WWII and the 42nd percentile since 1990. Pretty darn normal. Maybe people are comparing to very recent times (I would argue in error) and have been lulled into a false sense of calmness now shattered by 2016? Nope, it’s still only at the 54th percentile when compared to the last five years. Realized daily volatility simply was not high in 2016 compared to pretty much any prior period (it certainly wasn’t exceptionally low either).
The S&P 500 was +9.5% in price return in 2016.
