Midterm Wins: Stocks Rally Higher as Democrats Flip Congress, Raising Questions for Markets

Markets React to Election Results

The U.S. stock market climbed sharply Wednesday as investors considered the effects of Democrats’ midterm election victories. The outcome could influence issues tied to investment returns, including data center development, cryptocurrency rules and proposals to limit credit card interest rates.

Stephen Brown of Capital Economics said the results did not substantially alter the near-term policy outlook. He pointed to the lack of a filibuster-proof Senate majority and President Trump’s veto power.

Gridlock May Limit Federal Changes

Investors expect the results to intensify congressional gridlock, with Democrats in control of both the House and Senate and Trump threatening to veto legislation he opposes. Analysts said that could constrain changes at the federal level. One assessment said sweeping policy changes were unlikely, while affordability, energy policy and artificial intelligence opportunities could offer areas for agreement under divided government.

State Decisions Also Matter

Jeff Buchbinder of LPL Research said federal policy effects may be limited, but data center decisions are also made by states and utility commissions. He said gubernatorial and utility races matter alongside congressional contests. Buchbinder cited Governor Abbott’s loss in Texas as an example of why state-level election outcomes could be relevant to data center policy.

Historical Market Performance

Stocks have generally performed well after midterm elections. Edward Jones figures show the S&P 500 rose an average of 15.5% during the six months after the previous 14 midterm elections, dating to 1970.
