Wells Fargo and JPMorgan map out stock market moves for election night

Investors face a split decision on election day as Wall Street firms prepare for divergent market reactions based on the outcome. If Democrats secure both chambers of Congress, the S&P 500 is expected to fall by roughly 0.5% on Wednesday, according to JPMorgan. In contrast, a Republican hold of both houses would likely trigger a short-term relief rally. Analysts at Wells Fargo Investment Institute noted that the market has a clear playbook for a Republican scenario, which provides a sense of certainty that a Democratic win may lack.

A split outcome, where Republicans keep the Senate but lose the House, could serve as a tailwind for equities. Citi strategists suggest this result would support stock prices through the end of the year. JPMorgan traders forecast that such a division could trigger a pop of up to 1% in the market on Wednesday. Tobin Marcus, head of U.S. policy and politics at Wolfe Research, said his firm’s survey of more than 100 institutional investors shows traders are not strongly positioned for any specific result. He described the current sentiment as begrudging acceptance rather than full conviction in a blue wave, noting that polling may be overstating Democratic strength.

Sector-specific impacts vary by the political winner. A strong Democratic showing, particularly in the Texas governor race, could accelerate a sell-off in artificial intelligence stocks. Rob Rains at Washington Analysis stated that increased Democratic control would add momentum to restrictions on data centers, solidifying cautionary signs regarding AI infrastructure. Defense stocks may face pressure from fears of spending limits, although Alex Sagal at Wells Fargo noted that the earnings outlook for the defense industry remains stable to modestly positive. Healthcare stocks could see a boost, with Jed Ellerbroek of Argent Capital Management monitoring hospital-related stocks and health insurers for potential gains.

Financials, which have lagged in early 2026, could face further instability under Democratic control. Democrats may seek to pass credit card rate caps to demonstrate progress on affordability. Matthew Aks of Evercore ISI suggested that President Trump could align with Democrats on populist issues to target specific industries. Additionally, a potential escalation in the conflict with Iran could cause energy stocks to outperform and disrupt the typical year-end rally.

Historical patterns suggest a bullish trend in the months following midterm elections. The S&P 500 has typically risen one year out after every midterm election since the early 1980s. However, Jonathan Krinsky, chief market technician at BTIG, pointed out that the index has already recorded double-digit gains in 2026. He observed that stocks usually perform well in November because they are weak heading into the election, but the current setup is the opposite. Krinsky noted that the S&P 500 has typically experienced a 14% drawdown at some point in the second half of midterm years, making a post-midterm rally less likely than consensus suggests.

The market reaction will occur on Wednesday following the election. Analysts are watching for immediate moves in the S&P 500 and sector-specific shifts in technology, defense, and healthcare. The final tally of seats in the House and Senate will determine which of the three primary scenarios unfolds. Investors are currently positioned for uncertainty rather than a definitive outcome, waiting for the final count to trigger their predefined trading strategies.
