Analysis-Fearless US stock market vulnerable to shocks as midterms loom

Two months before the U.S. midterm elections, the options market reveals a precarious blend of vulnerability and resilience, according to analysts. Despite recent bond market turbulence, stocks remain close to record highs, with volatility measures near their lowest levels since 2026 and equity market correlations nearing record lows.

While analysts don't anticipate the elections to trigger a significant market reaction, the buildup to the November 3 vote could be turbulent. Investor focus might shift to the uncertainty surrounding control of Congress and its policy implications, coupled with the risk of a divided or fragile government, which could heighten volatility, according to experts.

Historically, the September-October period preceding midterms has been a volatile time for equities, with the S&P 500 plunging 5% or more in 15 of the 24 midterm years since 1930. However, the Cboe Volatility Index (VIX), a gauge of investor anxiety, has recently hit a new low for the year, signaling a lack of market unease. The absence of a VIX premium for midterm elections suggests that markets are confident in strong corporate earnings to sustain growth.

Analysts note that the elections could have market implications, as the Democratic Party has gained a substantial lead in public perception regarding which party better addresses the cost of living. A shift in control of the House of Representatives could introduce uncertainty into markets, while a Senate flip would amplify this effect.

The market's apparent brashness, coupled with a host of sentiment indicators, including crowded positioning, tight credit spreads, and limited demand for protection, indicates that the market may be unprepared to handle any shock. Turbulence, a machine-learning framework used by UBS to gauge market vulnerability over the next month, has reached an extreme level of potential stress in recent weeks.

Despite being unfazed by recent geopolitical tensions and a tumultuous bond market selloff, analysts caution that there is little room for error. So far, the market seems to expect only solid earnings and robust economic growth to support stocks, regardless of the midterm results. While some investors find the current calm around the midterms appropriate, given that stocks are likely to remain supported by strong earnings, those who have recently taken hedge positions have little to show for their efforts.
