The presidential election cycle theory says S&P 500 returns follow a four-year rhythm tied to the election calendar, with year three (the pre-election year) historically the strongest and year two (the midterm year) the weakest. The averages are real in the historical record, but the sample is tiny and the pattern is not a reliable trading signal.
Key takeaways
- The cycle divides a presidential term into four years: post-election (year 1), midterm (year 2), pre-election (year 3), and election (year 4).
- Year three is historically the strongest for the S&P 500 and year two the weakest, a pattern first popularized by Yale Hirsch in the Stock Trader's Almanac.
- The exact averages shift with the start date. Since 1950 the pre-election year has averaged roughly 16 percent; measured since 1928 it drops to about 13.5 percent (CFA Institute).
- With only about 18 to 24 completed cycles in modern data, the sample is too small to treat as a dependable edge.
- For a buy-and-hold FIRE investor, this is a curiosity to understand, not a calendar to trade.
What the presidential cycle theory claims
The idea is simple. A sitting administration front-loads harder policy choices early in a term, then leans toward growth-friendly conditions as the next election approaches. The result, in theory, is soft returns around the midterms and a stronger run in the pre-election year.
Yale Hirsch documented the pattern in the Stock Trader's Almanac decades ago, and it has been repeated in market commentary ever since. The cycle maps cleanly onto today: with the presidential term that began in January 2025, 2025 is year one, 2026 is the midterm year, 2027 is the pre-election year, and 2028 is the election year. That places the current market in the historically weakest slot of the four.
Average S&P 500 return by cycle year
The table below shows the widely cited averages using price returns since 1950, the framing most commentators use. Read these as descriptive history, not forecasts.
| Cycle year | Description | Average S&P 500 price return (since 1950) |
|---|---|---|
| Year 1 | Post-election | about 7% |
| Year 2 | Midterm | about 5% to 6% (weakest) |
| Year 3 | Pre-election | about 16% to 17% (strongest) |
| Year 4 | Election | about 7% to 8% |
Source: Stock Trader's Almanac data, as commonly reported for S&P 500 price returns since 1950. Figures are approximate and vary by methodology and start date.
The year-three number is the headline everyone quotes, and recent history has cooperated. In 2023, a pre-election year, the S&P 500 rose about 24 percent on price and roughly 26 percent with dividends. That fit the script almost perfectly.
But the figure is fragile. The CFA Institute, measuring back to 1928, put the pre-election year at an average of 13.5 percent with gains 78 percent of the time, against an all-year average of about 7.7 percent. Same pattern, materially smaller edge, simply because the window is longer. When a headline average can move several points based on whether you start counting in 1928 or 1950, that is a signal the number is soft.
Why it is a curiosity, not a strategy
Two problems keep this out of any serious FIRE playbook.
First, the sample size. Modern S&P 500 data gives roughly 18 completed cycles since 1950, or around 24 back to 1928. Each cycle year therefore rests on fewer than two dozen observations, well below what is needed for statistical confidence. A pattern that shows up in 18 or 24 data points can easily be noise dressed up as a rule. The CFA Institute treats the presidential cycle as a calendar anomaly, and anomalies tend to fade once they are widely known and traded.
Second, the pattern is easy to confound. Much of the year-three strength coincides with the secular bull markets of the 1980s, 1990s, and 2010s happening to line up with pre-election years. Strip out those decades and the effect weakens. Academic reexaminations have found that the term-year signal shrinks once you control for the broader business cycle, inflation, and Fed policy. The presidential year may just be standing in for where the economy sits in a longer cycle it has nothing to do with.
And the averages hide the misses. The pre-election year of 2007 turned negative as the financial crisis built, and 2008 (an election year) was catastrophic. When a recession or shock lands on a supposedly strong cycle year, the macro event wins and the calendar is irrelevant.
What this means for a FIRE portfolio
The practical answer is to do less than the commentary implies. Trying to overweight equities in year three and lighten up in year two means making a market-timing bet on a weak signal, and market timing is where returns go to die. It also triggers taxable events. For a large taxable portfolio, short-term gains taxed at top federal rates plus the net investment income tax can erase whatever thin edge the pattern might have offered, before you even account for the risk that the cycle simply does not show up this time.
Even professional managers struggle to beat a plain index over time, as the long record of hedge fund performance versus the S&P 500 shows. If full-time investors with research teams cannot reliably time the market, a four-year calendar heuristic will not do it for you either.
Where cycle awareness has modest value is in setting expectations and staying disciplined. Knowing that a midterm year has historically been choppier can keep you from panicking through volatility, and drawdowns are a reasonable prompt to rebalance to target or harvest tax losses. Both of those add value regardless of whether the cycle prediction holds. That is the difference between using the pattern as context and using it as a signal.
For the long-run picture that actually drives wealth, the S&P 500 hub and a comparison like the S&P 500 versus the Nasdaq 100 over the long term are far more useful inputs than the election calendar. The equity risk premium accrues to investors who stay invested across cycles, not to those who trade around them. If you want a durable framework, the fundamentals in the investing hub will serve a FIRE plan better than any four-year pattern.
The presidential cycle is a genuine historical observation and a fun piece of market trivia. It is not a reason to move real money.
Frequently asked questions
Which year of the presidential cycle is historically best for the S&P 500?
Year three, the pre-election year, is historically the strongest for the S&P 500, while year two, the midterm year, is the weakest. Since 1950 the pre-election year has averaged roughly 16%, though measured since 1928 it drops to about 13.5%. The pattern was first popularized by Yale Hirsch in the Stock Trader's Almanac.
Where does the current market sit in the presidential cycle?
The current market sits in the historically weakest slot. With the presidential term that began in January 2025, 2025 is year one, 2026 is the midterm year, 2027 is the pre-election year, and 2028 is the election year. That places 2026 in year two, the cycle's weakest year on average.
Is the presidential cycle a reliable trading strategy?
No, it is a curiosity, not a strategy. Modern data gives only about 18 to 24 completed cycles, so each cycle year rests on fewer than two dozen observations, too few for statistical confidence. Much of the year-three strength coincides with secular bull markets that happened to line up, and the effect weakens once you control for the business cycle, inflation, and Fed policy.
How should a FIRE investor treat the presidential cycle?
A FIRE investor should treat it as context, not a signal. Trying to overweight equities in year three and lighten up in year two is a market-timing bet on a weak signal, and it triggers taxable events that can erase any thin edge. Where cycle awareness helps is setting expectations and staying disciplined through choppy midterm years rather than panicking.
