Why Stock Market Tranquility is Unlikely to Last

Stock markets have been very quiet lately, but as we get ready to enter 2017, things may change. Here's why.

Ideally, the holidays should be calm. Thankfully the market is obliging. Equity market volatility, as measured by the VIX Index, recently dipped below 12, close to multiyear lows. We’ve seen this pattern repeatedly over the past 10 years and it rarely ends well.


We’ve been here before, most recently last summer. In late August I described the unusually low level of volatility. By early September the VIX Index had spiked roughly 70% compared to the August low. It repeated the pattern again around the U.S. election in November (see the chart above). We may be setting up for a similar pattern in early ’17. Here are three reasons volatility is unlikely to remain this low too far into 2017.

1. Equity investors are alone in their torpor.

While the VIX and other measures of equity market volatility are flirting with historic lows, volatility in other asset classes remains elevated relative to the summer levels. Currency volatility, as measured by the CVIX, remains about 20% above the fall lows. U.S. bond market volatility, measured by the MOVE Index, is off the November high but stays 30% above the October bottom. Only equity market investors are convinced that volatility will remain low in the near term.

2. Political Risk is elevated but not reflected.

Many factors, from credit market conditions to economic expectations, drive volatility. Not all are market related. Historically, equity market volatility has been correlated with general political and policy uncertainty. Using the Economic Policy Uncertainty Index as a proxy, since the mid-90s policy uncertainty has explained roughly 25% of the variation in the VIX Index. While the U.S. election is finally over, there is significant uncertainty as to the future direction of policy. The timing and form of corporate and individual tax reform, deregulation and trade policy remain in an indeterminate state. This should be adding to, not subtracting from, volatility.
