Shock The 'Short S&P 500 Volatility' Monkey

 | Feb 08, 2018 12:53AM ET

A top-tier financial web site interviews me at the start of every year. The interviewer typically asks me about specific securities, asset allocation, economic backdrop as well as the impact of events (e.g., central bank monetary policy, mid-term elections, tax reform, etc.)

This year, at the tail end of the interview , I fielded an atypical query. He wanted to know what “market surprise” might occur in 2018 (good or bad) that the financial media are not talking about.

I thought for a brief moment. Then, I answered with the following:

“You have scores of people who are doing nothing more than sticking with the trade that has worked so well for five-plus years, and that’s shorting volatility. Yet risk premia really cannot move much lower…”

“One aberration, one surprise or shockwave to the system, and volatility would soar. People are not prepared for the eventuality. Scores of traders/investors will get scorched by a rapid reversal in volatility pricing…”

Now, everyone’s talking about the violent short-vol unwind. Indeed, many blame the volatility event for the Dow’s 4.6% Monday beating. Even worse, the popular trade’s reversal completely wiped out participants in a matter of hours.
