Goldman Sachs predicts US stock market volatility will increase ahead of the upcoming midterm elections, according to a recent report cited by Investing.com on local time. The investment bank noted that historically, US stocks have shown no clear directional trend in the months leading up to midterm elections, with the S&P 500 posting a median return of 0% from early August to election day since 1974. The anticipated volatility stems from heightened policy uncertainty, exceptionally low implied correlation among S&P 500 components in the options market, and rapidly rising Treasury yields. Goldman Sachs highlighted that the 10-year real yield has reached its highest level since 2023, and a further 50 basis point increase within one month could trigger a market correction. This pattern reflects investors' tendency to reduce equity exposure during late summer before midterm elections, then increase allocation after political uncertainty clears.
S&P 500 Shows Flat Pre-Election Performance Since 1974
Since 1974, the S&P 500 has delivered a median return of 0% from early August through election day during midterm election years, according to Goldman Sachs' historical analysis. However, the index has typically gained 6% in the three months following the election as political uncertainty dissipates. Goldman Sachs explained that investors have historically reduced their stock allocations during late summer ahead of midterm elections due to economic policy uncertainty, then expanded positions after the election concludes.
Implied Correlation Hits Multi-Decade Low in Options Market
Goldman Sachs assessed that this year's market structure increases the likelihood of expanded index-level volatility. The implied correlation among S&P 500 constituents in the options market has recently moved between 9 and 10, reaching the lowest level in decades. This indicates that while individual stocks are experiencing large price swings, overall index volatility has remained relatively suppressed. Goldman Sachs forecasted that once earnings season concludes, investor attention will shift to macroeconomic issues including the election, inflation, and interest rates, likely amplifying index volatility.
Treasury Yield Rise Poses Correction Risk
Goldman Sachs identified Treasury yields as a critical risk factor. US Treasury yields have risen sharply in recent periods, with the 10-year real yield climbing to its highest level since 2023. Goldman Sachs noted that historically, stock markets have underperformed when Treasury yields rise at an unusually rapid pace. The firm estimated that if the 10-year Treasury yield increases by approximately 50 basis points within one month, the stock market faces a high probability of correction.
Prediction Markets Price 85% Probability of Democratic House Majority
Goldman Sachs stated it does not expect the election outcome itself to significantly alter market trends. Prediction markets currently reflect an approximately 85% probability that Democrats will retake the House majority, while the Senate race remains a toss-up. Goldman Sachs analyzed that since investors have already substantially priced in this scenario, broader economic changes are more likely to drive market volatility than unexpected legislative outcomes. The firm also noted that sector-level stock prices have not moved in response to election polling shifts. Over recent months, most sectors, investment styles, and thematic portfolios have shown no statistically significant correlation with changes in election win probabilities in prediction markets.
Goldman Sachs Sets 2026 S&P 500 Target at 8,000
Separate from midterm election analysis, Goldman Sachs maintained its long-term optimism on US stocks. The firm forecasted S&P 500 earnings per share of $340 for 2026 and $385 for 2027. Goldman Sachs kept its end-2026 S&P 500 target at 8,000 and its 12-month target at 8,300.
