The presidential election cycle stock market theory says US stocks tend to follow a four-year pattern tied to each presidential term. Historically, the second year (the midterm year) has been the weakest, while the third year (the pre-election year) has often been the strongest. The pattern is a historical tendency, not a reliable forecast.
Think of the cycle as a seasonal tide rather than a timetable. Tides are real, but storms, currents and wind can easily overpower them on any given day. The intention is to inform, not to advise.
Key takeaways
- The theory: US stocks have tended to move in a four-year rhythm linked to the presidential term, an idea popularised by Yale Hirsch of the Stock Trader’s Almanac.
- The pattern, 2001 to 2024: Average S&P 500 calendar-year price returns were up 14.9% in year 1, down 1.9% in year 2, up 13.7% in year 3 and up 5.5% in year 4.
- The midterm turn: Since 1950, the S&P 500 has averaged a 15.17% return in the year after midterm elections, against 7.30% in all other years, according to Hartford Funds citing Morningstar.
- Where we are now: The 2026 midterms closed year 2 of the current term, and 2027 is a pre-election year.
- The caveat: Big exceptions exist, from the 2008 financial crisis to the 2022 inflation shock. Economic conditions usually matter more than the calendar.
- Take note: No historical pattern guarantees future returns.
What is the presidential election cycle in the stock market?
The presidential election cycle is a market theory that links US stock returns to the four years of a presidential term. Each term is split into:
- Year 1: The post-election year, when a new or re-elected president takes office
- Year 2: The midterm year, when Congress is elected halfway through the term
- Year 3: The pre-election year, when the next presidential race begins to take shape
- Year 4: The election year, ending with the November vote
The idea was brought to wide attention by Yale Hirsch, who founded the Stock Trader’s Almanac in 1967. He noticed that US stocks had tended to perform better in the second half of a presidential term than in the first.
The theory is usually tested on the S&P 500, the benchmark index of 500 large US companies. Because US markets lead global sentiment, investors in Europe and Asia watch the cycle too. The wider relationship between elections and share prices is covered in the guide to US elections and the stock market.
A brief history of the theory
The presidential election cycle is one of the oldest calendar patterns in investing. Yale Hirsch launched the Stock Trader’s Almanac in 1967 as an annual guide to seasonal and political patterns in the market. Among its best-known observations was that the second half of a presidential term had historically delivered far better returns than the first half.
The idea gained wider attention as more data accumulated. Analysts at banks, fund managers and research firms began tracking returns by year of the term, often going back to the 1950s or earlier. The basic shape, a weak midterm year followed by a strong pre-election year, has appeared in many of these studies, though the exact numbers vary depending on the period and method used.
Today, the cycle is widely quoted around every midterm and presidential election, especially in the months after a midterm vote, when the historically strong stretch is said to begin.
The cycle year by year: what typically happens
Each year of the term has its own political character. The examples below show how those themes have played out.
Year 1: the post-election year
A new administration sets out its agenda. Markets digest Cabinet appointments, early executive orders and the first legislative push. Returns have varied widely. 2001 fell 13.0% as the dot-com bust and recession deepened, while 2013 rose 29.6% and 2021 gained 26.9% as economic recoveries gathered pace.
Year 2: the midterm year
Uncertainty over control of Congress often weighs on sentiment, and the president’s party historically tends to lose seats. Midterm years have included some of the cycle’s worst outcomes, such as 2002 (down 23.4%) and 2022 (down 19.4%). Yet 2006, 2010 and 2014 all rose by double digits, a reminder that the economic backdrop matters most.
Year 3: the pre-election year
With the next presidential race approaching, attention turns to growth and jobs. This year has often delivered the strongest returns of the cycle, including 2003 (up 26.4%), 2019 (up 28.9%) and 2023 (up 24.2%). It has also produced flat years, such as 2011 and 2015.
Year 4: the election year
Election years combine campaign uncertainty with the final push for growth. They have usually been positive, but 2008 showed that a financial crisis can overwhelm any election effect, with the S&P 500 falling 38.5%.
Why might stocks follow a four-year cycle?
Several explanations have been suggested. None proves the cycle exists, but together they explain why many investors take it seriously.
The policy timing argument
New administrations often push difficult or unpopular measures, such as spending cuts, tax rises or tougher regulation, early in a term. That leaves time for the political cost to fade before the next election.
The pre-election stimulus argument
As the next election approaches, governments have a strong incentive to support growth and employment. Tax changes, spending and supportive rhetoric can lift confidence in years 3 and 4.
The midterm uncertainty argument
Midterm years bring uncertainty over control of Congress. Markets often hesitate until the result is known, then rally once the balance of power is clear. A shift to divided government can also reduce the risk of sweeping policy changes.
The behavioural argument
Some analysts argue that investor psychology plays a role. If enough market participants expect a strong pre-election year, their positioning can help create it.
| Explanation | What it suggests | Main weakness |
|---|---|---|
| Policy timing | Tough measures come early in a term | Many policies are driven by events, not timing |
| Pre-election stimulus | Governments support growth before a vote | The Federal Reserve sets interest rates independently |
| Midterm uncertainty | Markets rally once Congress is decided | The size of the rally varies widely |
| Behavioural | Expectations become self-fulfilling | Hard to measure or prove |
Presidential election cycle stock market returns: the data
Presidential election cycle stock market returns look clearest when each term is broken down year by year. The table below uses S&P 500 calendar-year price returns from 2001 to 2024.
| Presidential term | Year 1 | Year 2 (midterm) | Year 3 (pre-election) | Year 4 (election) |
|---|---|---|---|---|
| 2001 to 2004 | Down 13.0% | Down 23.4% | Up 26.4% | Up 9.0% |
| 2005 to 2008 | Up 3.0% | Up 13.6% | Up 3.5% | Down 38.5% |
| 2009 to 2012 | Up 23.5% | Up 12.8% | 0.0% | Up 13.4% |
| 2013 to 2016 | Up 29.6% | Up 11.4% | Down 0.7% | Up 9.5% |
| 2017 to 2020 | Up 19.4% | Down 6.2% | Up 28.9% | Up 16.3% |
| 2021 to 2024 | Up 26.9% | Down 19.4% | Up 24.2% | Up 23.3% |
| Average | Up 14.9% | Down 1.9% | Up 13.7% | Up 5.5% |
What stands out
- Midterm years were the weakest on average, with three of six years negative.
- Pre-election years were mostly strong, with three gains above 24%, though 2011 and 2015 were flat.
- Election years were positive five times out of six, with 2008 the major exception.
- The averages hide huge variation. Year 4 ranged from a 38.5% fall to a 23.3% gain.
Over longer periods, studies have found a similar shape. Hartford Funds, citing Morningstar data from 1950 onwards, describes year 3 as historically the strongest year of the four-year cycle.

The stock market presidential election cycle chart below shows average S&P 500 calendar-year price returns for each year of the term, from 2001 to 2024.
Stock market presidential election cycle chart showing average S&P 500 returns by year of the presidential term, 2001 to 2024
| Year of term | Average return | Visual |
|---|---|---|
| Year 1: post-election | Up 14.9% | ███████████████ |
| Year 2: midterm | Down 1.9% | ▒▒ (negative) |
| Year 3: pre-election | Up 13.7% | ██████████████ |
| Year 4: election | Up 5.5% | ██████ |
The shape is often described as a dip in the middle of the term followed by a recovery. Charted over many decades, the midterm year typically forms the low point, with returns improving from the midterm election through the pre-election year.
Take note that chart averages smooth out the extremes. A single crisis year, such as 2008, can drag an average down sharply, while a strong recovery year can pull it up.
The midterm turn: the most-watched part of the cycle
The period from the midterm election to the end of the following year has drawn particular attention.
- According to Hartford Funds, citing Morningstar, the S&P 500 has averaged a 15.17% return in the year after midterm elections since 1950, compared with 7.30% in all other years.
- According to TradingView data reported by Benzinga, the S&P 500 rose in the 12 months after the October close in all 19 midterm election years since 1950, with an average gain of 16.6%.
Why the midterm turn may happen
- Uncertainty over control of Congress is removed.
- Divided government, a common midterm outcome, can limit major policy shocks.
- Political attention turns to the next presidential election, when growth and jobs become priorities.
The weakest post-midterm year in that series was a gain of about 3%, from October 2014 to October 2015. Even a historically consistent pattern can produce modest results. Midterm-year behaviour is explored further in the guide to midterm election years and the stock market.
Where are we in the cycle now?
The current presidential term began in January 2025. That places:
| Year | Cycle position | Status |
|---|---|---|
| 2025 | Year 1: post-election | The S&P 500 posted a double-digit gain, its third in a row |
| 2026 | Year 2: midterm | Midterms held on 3 November 2026; Democrats won control of Congress |
| 2027 | Year 3: pre-election | Historically one of the stronger years of the cycle |
| 2028 | Year 4: election | Presidential election on 7 November 2028 |
The day after the 2026 midterms, the S&P 500 rose 1.59% to 7,689 and the Dow gained 3.03% to 53,356, its best post-midterm day in 44 years, according to The Motley Fool. Falling oil prices, lower Treasury yields and the end of election uncertainty all helped.
What could disrupt the pattern in 2027
- Interest rates: The Federal Reserve raised rates in September 2026 and held them in late October. Further tightening could weigh on valuations.
- Inflation and oil: The conflict involving Iran has kept energy prices volatile, as explained in the guide to how US elections affect oil prices.
- Valuations: After three years of strong gains, starting valuations are higher, which can limit future returns.
- Earnings: Corporate profits, especially around artificial intelligence investment, will matter more than the calendar.
The limits of the presidential election cycle
The cycle is popular, but it has real weaknesses that every reader should take note of.
Small sample size
There are only a few dozen presidential terms in the modern market record. Patterns drawn from so few data points can be distorted by a handful of unusual years.
Big events overwhelm the calendar
The dot-com crash, the 2008 financial crisis, the 2020 pandemic and the 2022 inflation shock all had far larger effects on returns than the position in the cycle. 2008, an election year, fell 38.5%.
Correlation is not causation
Even if returns line up with the cycle, that does not prove politics causes the pattern. Business cycles, interest rate cycles and global events may simply happen to overlap.
Markets learn
When a pattern becomes widely known, investors may try to profit from it in advance, which can weaken or shift it.
It says nothing about individual stocks or sectors
The cycle describes broad index averages. Individual sectors and companies can behave very differently, depending on policy, earnings and competition.
The presidential cycle vs other market cycles
The presidential election cycle is only one of several cycles that analysts track. In practice, these cycles overlap, and the larger ones usually dominate.
| Cycle | What it describes | Typical length |
|---|---|---|
| Presidential election cycle | Stock returns linked to the four years of a presidential term | Four years |
| Business cycle | Expansion, peak, recession and recovery in the economy | Several years, varies widely |
| Interest rate cycle | Periods of central bank tightening and easing | Often one to three years per phase |
| Earnings cycle | Rising and falling corporate profit growth | Varies with the economy |
| Seasonal patterns | Calendar effects such as historically weaker summer months | Within a single year |
How they interact
- When cycles line up: A pre-election year that coincides with falling interest rates and rising earnings has historically been a supportive mix.
- When cycles clash: A pre-election year during a recession or an aggressive rate-hiking cycle may see the presidential pattern overwhelmed.
- Which matters most: The business cycle and the interest rate cycle have generally had the biggest influence on returns. The presidential cycle is best seen as a secondary layer.
This is why the 2027 outlook depends heavily on the Federal Reserve’s next moves and on corporate earnings, not just on its position as a pre-election year.
Does the cycle apply to markets outside the US?
The presidential election cycle is a US theory, but its influence can reach other markets.
- Global correlation: Major stock markets in Europe and Asia often move with Wall Street, so a strong or weak US year can lift or weigh on them.
- Dollar effects: Election-driven moves in the US dollar can affect emerging market stocks and the earnings of exporters worldwide. More detail is in the guide to how US elections affect the US dollar.
- Local politics: Each country has its own election calendar and economic cycle, which can matter more for local markets than the US cycle.
For global traders, the cycle is best treated as one piece of background context, alongside local conditions and global data such as US gross domestic product (GDP) and inflation.
How traders use the cycle in practice
Some traders use the cycle as context rather than a trading signal. Common approaches include:
- Setting expectations: Being prepared for higher volatility in midterm years and around election days.
- Watching the midterm turn: Paying attention to how markets behave after the midterm result is known.
- Combining with other signals: Using the cycle alongside earnings trends, interest rates and technical analysis rather than on its own.
- Planning around key dates: Election days, Federal Reserve meetings and major data releases such as the Consumer Price Index (CPI) can all drive short-term moves.
Index exposure can be gained through instruments such as ETFs or index CFDs, each with different costs and risks. A guide to indices trading explains how benchmark indices are traded.
Precautions to take note of
- Averages are not forecasts. Individual years can be far above or below the average.
- Volatility can rise around elections. Results days and midterm periods can bring sharp moves and overnight gaps.
- Leverage magnifies both gains and losses. Position sizing and a clear stop loss and take profit plan help manage risk.
- Protection features matter. Understanding negative balance protection is a sensible reminder before any major event.
- Diversification still applies. Relying on one calendar pattern concentrates risk.

Frequently asked questions
What is the presidential election cycle theory?
The presidential election cycle theory suggests that US stocks follow a four-year pattern linked to the presidential term. Historically, the midterm year has been the weakest and the pre-election year one of the strongest. The idea was popularised by Yale Hirsch of the Stock Trader’s Almanac.
Which year of the presidential cycle is best for stocks?
Historically, year 3, the pre-election year, has often been the strongest. Hartford Funds, citing Morningstar data since 1950, describes it as the strongest year of the cycle. Between 2001 and 2024, years 1 and 3 averaged similar double-digit gains, while midterm years averaged a small loss.
Is 2027 a pre-election year?
Yes. The current presidential term began in 2025, so 2026 was the midterm year and 2027 is the pre-election year, year 3 of the cycle. The next presidential election is on 7 November 2028. Historical strength in year 3 does not guarantee gains in 2027.
Does the presidential election cycle really work?
It describes a historical tendency, not a rule. Major events such as the 2008 financial crisis and the 2022 inflation shock have overwhelmed the pattern in some years. The sample of presidential terms is small, so many analysts treat the cycle as useful context rather than a trading signal.
