The S&P 500 first half 2026 result was a price gain of 9.6%, from 6,845.50 on December 31, 2025 to 7,499.36 on June 30, 2026, and a total return of 10.2% including dividends [1][2]. The path was not smooth: the index fell 4.6% in the first quarter to 6,528.52 on March 31, then rose 14.9% in the second quarter and set a record close of 7,609.78 on June 2 [1]. Leadership came from semiconductor and memory stocks, industrials and energy, while financials and consumer discretionary finished the half slightly lower [2].
How the S&P 500 first half 2026 unfolded quarter by quarter
The first quarter was a correction. Oil prices rose sharply in March after supply disruptions in the Middle East, inflation expectations moved up, and the index closed the quarter at 6,528.52, down 4.6% from year-end [1]. The second quarter reversed that loss and more. The index gained 14.9% between March 31 and June 30, one of its strongest quarters in decades, and set a new all-time high on June 2 before easing about 1.5% into the end of June [1]. On July 7 the index closed at 7,503.85, essentially unchanged from the half-year mark [1].
The breadth of the rally was better than in 2024 or 2025. According to RBC Wealth Management, 62% of S&P 500 stocks rose in the first half, the average stock gained 13.2% and the median stock gained 7.4% [2]. The equal-weight version of the index returned 12.1%, ahead of the cap-weighted index, which is the opposite of the pattern of the previous two years [2].
Which sectors led and which lagged
Three sectors returned close to 20% in the first half, and two finished in negative territory. RBC's tally of the 11 S&P 500 sectors is shown below [2].
| Sector | H1 2026 return |
|---|---|
| Industrials | +20.2% |
| Information Technology | +19.8% |
| Energy | +19.7% |
| Materials | +12.0% |
| Real Estate | +11.5% |
| Consumer Staples | +8.0% |
| Utilities | +7.7% |
| Health Care | +3.5% |
| Communication Services | +0.8% |
| Consumer Discretionary | -0.8% |
| Financials | -1.2% |
Energy's place near the top reflects the oil price shock of the first quarter, which lifted producer earnings even as it weighed on the broader index. Industrials benefited from data center construction, power equipment and aerospace demand. Financials, the worst sector, lagged despite record trading revenues, partly because the group had already rallied hard in 2025 and partly because a steeper yield curve raised funding costs for some lenders.
The semiconductor concentration
The AI theme still dominated the leaderboard, but the winners changed. In 2024 and 2025 the largest contributors were the hyperscale cloud companies; in the first half of 2026 they were the chip and memory suppliers. RBC calculates that Micron Technology (MU) alone accounted for 16% of the index's gain after its shares rose 304%, Advanced Micro Devices (AMD) contributed 10% after a 171% advance, and Intel (INTC) contributed 8% after a 278% gain [2]. Alphabet (GOOGL) contributed 8%, Nvidia (NVDA) 6.2%, Applied Materials (AMAT) 6.1%, Lam Research (LRCX) 5.5% and SanDisk (SNDK) 5.0% [2]. The Philadelphia Semiconductor Index rallied just over 100% in the six months [2].
Nine of the twelve largest contributors were semiconductor or memory companies. That concentration cuts both ways: it produced the gain, and it means the second half depends heavily on whether the capital spending plans of the large cloud providers hold.
Earnings, not multiples, did most of the work
The valuation of the index rose only modestly during the half because earnings estimates rose almost as fast as prices. FactSet's Q2 2026 preview, published July 2, shows the expected year-over-year earnings growth rate for the second quarter at 23.3%, up from 18.8% on March 31, and expected revenue growth at 12.2%, up from 9.5% [3]. Estimated Q2 earnings per share rose 3.4% during the quarter, when the typical pattern is a decline [3]. For calendar 2026 analysts now project earnings growth of 24.1%, with 26.8% for the third quarter and 24.4% for the fourth [3].
Company guidance backed the upgrades. Of the 111 S&P 500 companies that issued Q2 EPS guidance, 63 (57%) guided above consensus, compared with a 5-year and 10-year average of 41% [3]. RBC notes that the consensus forecast for 2026 index earnings growth climbed from 13.6% at the start of the year to 23.3% by the end of June, with 2027 growth expected at 16.1% [2].
Trailing multiples still look demanding in the sectors that led. DataPorium's sector P/E series for Nasdaq-listed companies shows a trailing P/E of 47.5 for Technology and 81.8 for Consumer Cyclical on July 7, 2026, against 17.1 for Energy, 18.8 for Industrials and 20.5 for Financial Services [4]. Investors can compare these readings daily on DataPorium's stock market dashboard and rank individual constituents with the stock screener [4].
Beyond the large caps
Smaller companies did better than the S&P 500. The S&P SmallCap 600 returned 23.9% in the first half and the S&P MidCap 400 returned 17.3%, while the Nasdaq Composite returned 13.1%, the S&P 500 Growth index 12.0% and the Dow Jones Industrial Average 9.8% [2]. The pattern is consistent with a market that broadened out from a handful of mega-cap names to a wider set of beneficiaries of the capital spending cycle, from equipment makers to regional industrial firms. Key observations from the half:
- The S&P 500 gained 9.6% in price terms and 10.2% in total return, with all of the gain coming in the second quarter [1][2].
- Small caps and mid caps outperformed, and the equal-weight S&P 500 beat the cap-weighted index [2].
- Semiconductor and memory stocks supplied most of the index's gain; Micron, AMD and Intel more than doubled [2].
- Consensus 2026 earnings growth for the index nearly doubled during the half, from 13.6% to 23.3% [2].
The first half of 2026 was an earnings-led rally in which chip suppliers, industrials and energy producers did the work while the largest cloud platforms and banks sat out.
Key takeaways
- The S&P 500 rose 9.6% in the first half of 2026 to 7,499.36, after a 4.6% first-quarter decline and a 14.9% second-quarter rebound [1].

- Q2 2026 earnings growth is expected at 23.3% with 12.2% revenue growth, and 57% of guiding companies raised their outlook [3].
- Trailing P/E ratios remain highest in Technology (47.5) and lowest in Energy (17.1) as of July 7, 2026 [4].
