Equity markets have been under pressure, with major US indexes down 4% to 7% in the second week of October alone, and market volatility has spiked. Depending on whom you talk to, the reasons for the sell-off and increased volatility vary. They include:
- Rising US rates. Ten-year Treasury yields have risen to over 3.2%.
- Increased trade tensions. There’s fear that the Trump administration’s posture toward China will eventually take a bite out of corporate profits.
- Technology stocks. Many have argued that a reversion to the mean for these high-flying stocks was long overdue, given their valuations.
It’s interesting to note that so far the sell-off in equities has not spread into risk aversion in other markets. Credit spreads, typically a leading indicator of broad-based stress, have widened but remain tight by historical standards. Further, currencies that would be expected to perform poorly in a risk-off environment—such as the Turkish lira and the South African rand—have been stable versus the US dollar. At this point all indications are that we’re not experiencing a panic-driven sell-off but rather a more orderly market pullback, which is to be expected in a more volatile market environment like the one we’re in today.
Is market volatility simply getting back to normal?
As we noted in an earlier blog post, the volatility we’ve witnessed in 2018 is something we should probably consider more normal. Think about the overall environment we’re in today: The Fed is transitioning from a historically accommodative monetary policy to a more restrictive posture. At the same time, equity valuations by any measure are fair to rich, but not cheap. Thus, the margin for error is less. Disappointing earnings announcements or economic data could create downward pressure on the market, which leads to volatility.
In fairness, US equity markets feel more volatile to investors because in 2018 we transitioned from the low-volatility environment we experienced in 2017. This transition to a higher-volatility environment has led to some very large one-day changes in the Cboe Volatility Index, also known as the VIX. In fact, Goldman Sachs reported that three of the top 25 one-day moves in the VIX since 1994 have occurred in 2018.1
Are stocks and bonds becoming too correlated?
Another concern for investors in this environment is the loss of diversification. As you can see in the chart below, the correlation between equities and bonds has been trending up in recent years as the Fed has begun to tighten rates and reduce its balance sheet. Large fiscal deficits, or an abundance of supply, are also putting upward pressure on rates. Overall, the increase in correlation reduces the diversification benefit investors receive from holding fixed income.

The best response to market volatility
So where are investors to go if they’re concerned about the volatility in the equity markets and not inclined to put more money into fixed income? Is equity hedging the answer? Based on our research, hedging reduces expected returns. The only way investors can avoid this cost is by being incredibly successful at timing their hedge—not a likely scenario.
Another alternative for investors to consider is one that allows them to maintain some exposure to the equity market but in a defensive manner—one that seeks to capitalize on volatility by accessing the volatility risk premium. This objective is achievable in a liquid, transparent, non-levered format.
The bottom line
Equity market volatility is most likely here to stay. If this level of volatility is causing heartburn for an investor, it may be time to consider an alternative approach that achieves a similar long-term return objective as holding a fully invested equity portfolio—but with significantly less volatility.
