The S&P 500 staged an impressive rebound in the second quarter of 2026, surging nearly 15%. This performance places 2026 among the strongest second-quarter showings since 1950, a rare occurrence that historically signals further gains rather than market exhaustion. The strength of this rally suggests the current bull market may have significant room to run.
Ryan Detrick, chief market strategist at Carson Group, analyzed historical instances where the S&P 500 gained more than 10% during the second quarter. The data reveals that the final six months of the year finished higher in eight of the nine prior cases, representing an 88.9% hit rate. The average gain for the remainder of the year following these strong quarters was 11.7%.
| Date of Quarter End | Q2 Return | Q3 Return | Q4 Return | Final Six Months |
|---|---|---|---|---|
| 6/30/1955 | 12.2% | 6.4% | 4.1% | 10.8% |
| 6/28/1968 | 10.4% | 3.1% | 1.2% | 4.3% |
| 6/30/1975 | 14.2% | -11.9% | 7.5% | -5.3% |
| 6/30/1980 | 11.9% | 9.8% | 8.2% | 18.8% |
| 6/30/1997 | 16.9% | 7.0% | 2.4% | 9.6% |
| 6/30/2003 | 14.9% | 2.2% | 11.6% | 14.1% |
| 6/30/2009 | 15.2% | 15.0% | 5.5% | 21.3% |
| 6/30/2020 | 20.0% | 8.5% | 11.7% | 21.2% |
| 6/30/2025 | 10.6% | 7.8% | 2.3% | 10.3% |
| Average | 5.3% | 6.1% | 11.7% | |
| % Higher | 88.9% | 100.0% | 88.9% |
Detrick noted that momentum is a real factor, pointing out that in 41 instances since 1950 where the S&P 500 gained more than 10% in a single quarter, the index moved higher over the following quarter 85% of the time. The median return over the subsequent 12 months in these scenarios was 13.4%, indicating that strong market momentum tends to persist.
The data contrasts sharply with average market behavior. Across all years since 1950, the final six months of the year averaged a gain of just 4.9% and closed higher only 72.4% of the time. A second-quarter surge above 10% historically doubles both the typical return and the probability of a positive finish for the year.
| Metric | Strong Q2 (>10%) | All Years Since 1950 |
|---|---|---|
| Average Q3 Return | 5.3% | 0.8% |
| Average Q4 Return | 6.1% | 4.2% |
| Average Final Six Months | 11.7% | 4.9% |
| Positive Final Six Months | 88.9% | 72.4% |
While historical performance does not guarantee future results, markets currently face uncertainties including Federal Reserve policy, inflation dynamics, and geopolitical risks. However, if 2026 follows the historical playbook, investors could see another double-digit advance before year-end. A gain close to the historical average of 11.7% during the second half would lift the S&P 500 to 8,400 points.
How might upcoming Federal Reserve policy decisions impact the probability of the market sustaining this historical momentum?
What specific sectors are likely to lead the rally if the S&P 500 reaches the projected 8,400 points by year-end?
Could current inflation dynamics derail the historical trend of strong second-half performance following a Q2 surge?
