One of the most puzzling aspects of markets in 2023 for investors has been the relative weakness in volatility. This is despite a plethora of risks for the economy and markets including rising recession risk, elevated levels of inflation, a hawkish Fed, deep stresses in the banking system, and a looming debt ceiling standoff that seems certain to go till the deadline.

Yet, stocks are at their highest levels in more than a year, while volatility is at its lowest level in a couple of years. In an article for the Wall Street Journal, Caitlin McCabe discusses the potential impact of quant funds on volatility, and why it could potentially account for the discrepancy. 

Basically, quant funds have been piling into stocks even though most investors remain on the sidelines. Currently, these funds have a net exposure level to stocks that is the highest since December 2021, before the bear market started. In contrast, investors have a relatively low allocation to stocks and have reduced it this year. 

Some see risks in the concentrated positions of these quant funds which increase the odds of a market dislocation in the event of bad or unexpected news. Another factor in reduced volatility has been steady inflows from corporate buybacks. Overall, it’s been an exceptionally calm stretch with less than a 1% move for the S&P 500 in 36 out of the last 46 sessions. 

Finsum: One mystery for markets in 2023 has been the steady drop in volatility despite growing risks. One potential reason may be quant funds which are aggressive buyers of stocks.
