US stocks rallied in the second quarter, supported by a US–Iran peace deal and continued investment into AI infrastructure. Despite ongoing inflation, strong company fundamentals and better-than-expected earnings growth drove stocks higher.
US sector leadership reversed in the second quarter. Energy, the best performer in Q1, was the worst S&P 500 sector in Q2. Meanwhile, Technology started the year down -9%, then surged over 30% to lead the second quarter. The S&P 500’s rally was so strong that 30% of stocks reached all-time highs, including 61% of Technology stocks.
Bond returns were muted as yields rose throughout the quarter, with the 10-year Treasury yield reaching a peak of 4.68% in late May after a low of 3.9% in early March. Oil prices also peaked in late May. With the de-escalation of the Iran conflict, yields and energy prices have stabilized, with the 10-year Treasury yield closing the quarter at 4.46% and crude oil falling below $70 per barrel.
A resurgence in AI optimism fueled Technology and Industrial sector returns. Additionally, after several muted years, IPO activity is expected to rebound in 2026, led by AI-related issuance. SpaceX completed the largest IPO on record in June, raising $75 billion.
Earnings strength in 2026 has not only been better than expected, but broad-based. After years of large companies’ dominance, earnings across large, mid, and small companies are rising. Tech-related companies have been huge profit drivers, yet profits are up across most sectors. This year’s rise in the S&P 500 index is solely attributed to its earnings growth, with its valuation or price-to-earnings (P/E) ratio drifting lower since the end of 2025. After climbing 13% last year, earnings are expected to grow nearly 24% in 2026 and 17% in 2027.
Market participants had widely expected rate cuts in 2026, until energy prices spiked and inflation remained persistent. Job growth has also picked up, and the economy has remained quite resilient. Consequently, the growing consensus is that the Fed may implement at least one rate increase this year.
New Fed Chairman Kevin Warsh used his debut press conference to signal that the Fed is serious about fighting inflation and committed to the institution’s independence. No forecasts were provided. The fall in the price of gold and the dollar’s bottom since Warsh’s confirmation point to financial market confidence in the Fed. Inflation has remained sticky due to tariffs, oil prices, and technology price increases. Labor remains stable, adding an average of 92,000 jobs per month in 2026 as job openings climbed to 7.6 million.
Looking through shorter-term influences that led to recent inflation, both the economy and stock returns are being driven by a revolution of innovation and trillions of dollars of investment in new technology and energy infrastructure. Increased productivity and deflationary pressure are benefits that are likely to follow. The risk remains that the return on invested capital (ROIC) will fall short of expectations.
