What Does the VIX Curve See That Stocks Don’t?

One would logically expect that a market that is sanguine enough to consort with record highs would see a bright future. For starters, bear in mind that VIX is constructed to give the options market’s best estimate of volatility over the ensuing 30 days. At current levels, VIX implies average daily moves for the S&P 500 Index (SPX) of just under 1% per day (using the “Rule of 16”). The 200-day historical volatility for SPX is currently 23.79, about in line with the current VIX. Yet 20 and 66-day historical volatility readings are both around 15.5, well below VIX. That implies that markets are concerned that volatility could return to the more elevated levels seen earlier this year.

That concern seems more evident when one considers the VIX futures curve, displayed in the graph below. The current curve (orange) rises into the future months. It rises steadily until January, then remains firmly ensconced between 25 and 26. On one hand, the return to an upward sloping curve (“contango”) implies a return to normality in the availability of volatility protection. That is a significant change from the inversions that we saw earlier this year. But if few were truly sanguine, would VIX futures continue to predict volatility well above historical norms?

I believe that the nature of the current market move is somehow to blame. Unlike in previous bull markets, much of the rise has been fueled by options buying in highly capitalized technology shares. We have seen near-record lows in the put/call ratio and record highs in options volume and open interest. All that speculative fervor pushes volatility higher. It is seemingly more benign than when nervous investors clamor for put protection, but buyers of either puts or calls require someone to sell those options. Those sellers raise options prices in the face of demand as it becomes more difficult for them to hedge. Paradoxically, a bullish environment could perpetuate that trend, keeping VIX and other volatility measures at elevated levels.

What could upset this trend? A continuing surge in Covid before vaccines are widely available could dampen economic activity even further. Congressional gridlock makes fiscal stimulus unlikely, keeping the onus on a Federal Reserve that has continually stated that their options are relatively limited without fiscal help. Furthermore, much of the options buying has been coming from individual investors. We noted how much of the rise in individual investing coincided with the receipt of stimulus checks and other measures that reduced personal expenses. However, unless a lame-duck administration once again extends rent and student-loan moratoria, many of those individual investors may find themselves with fewer funds to invest in stocks and their options. 

Does that mean that volatility remains high one way or the other? High if money continues to flow into the options market, and high if it sells off if the flows stop or reverse? Perhaps that is what VIX is telling us.
