Stocks Soar as Democrats Take Control of Congress, Raising Questions for Investors

Markets react to election results

U.S. stocks climbed Wednesday as investors considered what the Democrats’ broad midterm wins could mean for markets and policy. The results may affect areas tied to investment returns, including data center development, cryptocurrency regulation and proposals to limit credit card interest rates.

Limits on federal policy change

Democrats control both chambers of Congress, but the party does not have a filibuster-proof Senate majority. President Trump has also threatened to veto legislation he opposes. Stephen Brown of Capital Economics said the Democrats’ gains were unlikely to alter the near-term policy outlook substantially, given those constraints.

Gridlock and investor expectations

Investors expect the election outcome to intensify congressional gridlock. Analysts anticipate few sweeping policy shifts, while identifying affordability, energy policy and artificial intelligence opportunities as possible areas of agreement.

Jeff Buchbinder of LPL Research said federal policy effects may be limited under divided government. He noted that data center decisions are made at the state and utility-commission level, making gubernatorial and utility races relevant alongside congressional contests.

Past midterm market performance

Stocks have often performed well after midterm elections. Edward Jones figures show the S&P 500 rose an average of 15.5% in the six months after the 14 midterm elections held from 1970 onward. The Mississippi Senate race remained unresolved in what was described as a surprisingly competitive contest.
