The S&P 500 index tracks 500 of the largest U.S. publicly traded companies, weighted by market capitalization. It is widely regarded as the best single gauge of the U.S. equity market.
The recent 10-year seasonal record for this index is notably bullish, with 60- and 90-day windows both showing 80% win rates and projected gains of 11% and 24% respectively from current levels. But midterm election year history tells a sharply different story: the 90-day outlook flips negative, with only 45.8% of periods finishing higher and an average loss of 0.80%, implying a pullback toward $6,340.
This divergence is the critical tension to watch. The S&P 500 tends to struggle mid-year in midterm cycles as political uncertainty peaks before autumn rallies typically emerge. Traders should monitor whether the broad 10-year momentum overrides the election-cycle headwind, particularly around the 60-day mark where the split is most pronounced.

Projection as of Mar 10, 2026 from closing price $6,795.99
Seasonal projection data for the S&P 500 reflects how the index has historically performed during this same calendar period across prior years. The consecutive pattern shows an 80% win rate, meaning the index closed higher 60 days later in 80% of comparable historical instances, with an average return of +1.7%.
The two bases here point in opposite directions, which is meaningful context. The consecutive pattern suggests relative strength, while the midterm election year pattern shows a 54.2% win rate and an average return of -0.3%, indicating the election cycle has historically created different conditions. Median returns are often more reliable than averages because they are less distorted by outlier years.
Seasonal patterns carry important limitations that users should understand. They cannot account for breaking news, policy shifts, earnings surprises, or geopolitical developments that may occur within the projection window. A high win rate reflects historical frequency, not a guarantee of any specific outcome.
Market participants often use seasonal data as one layer of analysis alongside fundamentals, technical indicators, and macroeconomic context. When the two bases diverge as they do here, that tension itself becomes useful information, signaling that historical precedent is less uniform and that other analytical inputs carry added weight in forming expectations.
