What configuration of government typically performs best?
Republicans entered the midterm elections with control of the White House and both chambers of Congress, but their narrow congressional majorities left both chambers in play. Democrats won control of the House and Senate, meaning President Trump will face a divided government when the new Congress takes office in January.
The shift in the Senate was particularly notable. Republicans entered the election with 53 seats, compared with 47 in the Democratic caucus, including two Independents. Democrats needed a net gain of four seats to take control. They exceeded that threshold, flipping Republican-held seats in Maine, Iowa, Ohio, North Carolina, Kansas, South Carolina and Texas, while holding the competitive open seat in Michigan.
Democrats also won the House, where Republicans entered the election with little room for losses. Allocating vacant seats to the party that previously held them put the pre-election balance at 220 Republicans to 215 Democrats. Democrats therefore needed a net gain of just three seats to take control, but their gains extended well beyond that threshold, overcoming some of the structural advantages Republicans had hoped to gain through redistricting.
While individual races and candidates were of course key determinants, the results also reflected the broader political environment. Midterms often serve as a referendum on the administration, and voter polling highlighted concerns about inflation and a desire for stronger congressional checks on presidential power.

Currently, the House of Representatives consists of 163 Republicans, 254 Democrats, 18 uncalled races. Current does not include uncalled races. Data are as of November 6, 2026.
The first two years of a president’s term are often a mad dash to check off as many campaign policy promises as possible. That is because often presidents have a unified government (control of Congress) after a general election, but Congressional control can often diminish or flip after the midterms, making it more difficult to achieve agenda items.
Below is an outlook for key policy items under continued Republican control vs. a divided Congress:
Affordability and homeownership are among the key existential concerns Americans are grappling with, but recently a new one has entered the fray: artificial intelligence. From the data center- buildout to the threat to jobs, opinions on AI are evolving. In fact, in 2022, 38% of Americans were more concerned than excited about AI. That jumped to 50% in 2025.
As massive capex pours into data center construction, 71% of Americans oppose local construction of data centers in their area, according to Gallup. Interestingly, the reasons cited were environmental and quality-of-life related, with only one-fifth of respondents mentioning cost implications such as higher utilities. This contrasts with the 77% of respondents in a recent Reuters/Ipsos poll that are concerned about AI making electricity costs higher.
Anxieties grow as the buildout translates to greater AI proliferation, and productivity gains threaten jobs. About 64% of U.S. adults think AI will result in fewer jobs.
Still, despite 71% of Americans thinking AI will make their personal information less secure, 43% of U.S. adults say it is important for the U.S. to be the world’s leader in developing AI. This highlights the tensions between the risks and opportunities artificial intelligence presents at a national level, which is why balanced regulation becomes a key consideration.
Thus far, the approach has been “innovate first, regulate later” with much of the regulatory activity happening at the state and local level rather than federally. Republicans’ approach has been light regulation with a focus on global competitiveness and national security, while Democrats have focused on consumer safeguards, labor protection, privacy and misinformation.
Despite early efforts, U.S. lawmakers have a long way to go on regulation – not only when it comes to establishing a framework but also garnering public support. Ipsos conducted a poll last year across 31 countries, and the U.S. scored the lowest with just 31% of respondents trusting their own government to regulate AI responsibly.
Political opinions are best expressed at the polls, not in a portfolio. One cardinal rule for investors: Don’t let how you feel about politics overrule how you think about investing.
The chart below shows a survey from the Pew Research Center asking Americans to rate economic conditions. The results show that Republicans often feel better about the economy under a Republican president, while similarly Democrats feel better about the economy under a Democratic president. Investors often make portfolio decisions based on their economic outlook.
Yet, average annual returns on the S&P 500 during the Obama administration of 16.3% and during the first Trump administration of 16.0% were almost identical and higher than the average return over the last 30 years of 10.3%. It is likely that the macro conditions, like ultra-low interest rates enjoyed during both Obama and Trump administrations, were a more influential driver of above-average returns during those periods, rather than the policy prescriptions each president espoused. Even as macro conditions have shifted, returns during the Biden administration and the second Trump administration have also easily exceeded long-term averages, owing to the strength of American companies, the aggregate health of the consumer and technological innovation.
Investors who did allow their political opinions to overrule their investing discipline may have missed out on above-average returns during political administrations they didn’t like.

Pew Research Center asks the question: “Thinking about the nation’s economy, how would you rate economic conditions in this country today… as excellent, good, only fair, or poor?” S&P 500 returns are average annualized total returns between presidential inauguration dates.

Elections are often a source of anxiety for investors because they introduce a new element of uncertainty to markets, which can result in lower returns and higher volatility. Since 1937, returns in midterm years were 9.2% on average vs. 13.3% in non-midterm years. Realized volatility was also higher.
However, simple averages don’t tell the full story. Midterm years have also coincided with particularly choppy years in the markets that have been entirely unrelated to the elections themselves. For example, 2018 and 2022 were both midterm years in which the stock market suffered negative returns. However, the pressure on the equity market came from the Federal Reserve hiking interest rates. Another notable negative midterm year: 2002, as the market bottomed out due to the tech wreck.
Still, markets may encounter some bumps along the way in midterm years, but those wrinkles tend to be smoothed out very quickly in the run-up to the election and thereafter regardless of the result. In fact, average returns were slightly negative in each of the three quarters preceding a midterm but then jumped an average of 6.6% in the fourth quarter.
If that’s the case, why not reduce equity exposure before the election and ratchet it back up once the polls close? History shows that markets begin to rally just under a month before election day, making timing the market a difficult task, and one that is clearly unrelated to the election result itself.
S&P 500 total return, 1937-2025
Investors always want to know how markets perform under different government configurations. Since 1937, markets returned 16.3% under unified Republican control, but 9.4% under a Republican president with a divided Congress.
While simple to compute, these returns tell investors very little about why markets performed the way they did and how markets are likely to perform in the future. Monetary policy, fiscal policy, economic growth, labor markets, corporate profits and valuations are much better indicators of future returns. Fiscal policy is driven by the government of course, but if we get some form of divided government, policy making has historically been much more constrained.
The economic context, not the political context, tends to be much more relevant to understanding historical market environments and returns.
