From First-Quarter Fear to Renewed Optimism

The second quarter of 2026 served as a powerful reminder that markets often begin to recover well before uncertainty fully clears.

After a difficult start to the year, investor sentiment reached a low point near the end of March as concerns around inflation, geopolitics, and rising interest rates weighed on risk assets. The S&P 500 bottomed on March 30 after declining roughly 7 percent on a year-to-date basis. From that point forward, markets staged a sharp rebound as investors gained confidence that the U.S. economy remained resilient, coupled with signs of potential de-escalation of the Middle East conflict, which began to push oil prices lower. Most important was the exceptionally strong Q1 earnings season, which saw 85 percent of S&P 500 companies beat earnings estimates by more than 15 percent in aggregate, pushing overall growth to 28.8 percent year over year, according to FactSet.

The second-quarter rebound was notable not only for its strength but also for its breadth across domestic and global markets. Indeed, each of the six equity market asset classes that we invest in advanced by double digits. Once again, the leader was Emerging Markets with a 24.1 percent return, largely driven by a few companies tied to the artificial intelligence (AI) trade in South Korea, which skyrocketed 89.7 percent, and Taiwan, which rose 48 percent. Similarly, the S&P 500 staged a sharp rally driven by its heavy technology exposure, gaining 15.2 percent during the second quarter.

However, while technology stocks were the only sector to beat the overall return of the index, returning 31.6 percent, leadership continued to shift as AI worked its way through the value chain of what is needed to bring it to life. From chipmakers to hyperscalers to data centers and now memory chip makers, the impact of AI is snaking its way through both the economy and markets. A list of the top-performing stocks during Q2 was heavily represented by memory chip and storage companies, such as SanDisk (SNDK), Seagate (STX), Micron (MU), and Western Digital (WDC), that are currently experiencing blockbuster returns given their strong earnings on the back of increased demand for the hardware needed to bring AI to life.

It wasn’t just Large-Cap U.S. stocks that rose; the S&P 400 Midcap Index advanced 14.5 percent for the quarter, while the S&P 600 Small Cap Index rose a robust 19.7 percent, and U.S. Real Estate Investment Trusts (REITs) rose 12.37 percent.

The relative laggard for the second quarter was International Developed stocks, which advanced “only” 11.08 percent as investors weighed the impact of higher oil prices and a general lack of AI-tied companies.

Lastly, after a volatile Q1 tied to rising oil prices on the back of the Middle East conflict, commodities faltered amid the U.S.-Iran Memorandum of Understanding (MOU) and planned reopening of the Strait of Hormuz, finishing the quarter down 8.08 percent. Meanwhile, bonds largely marked time but finished Q2 up 0.67 percent.
