Tech and Dow Lead Market Rally as S&P 500 Nears Record

The stock market staged a powerful rally last week, with the S&P 500 surging within 0.4% of its record close of 7,501 set on May 14. The tech-heavy Nasdaq and the Dow Jones Industrial Average rose 0.5% and 2.1%, respectively, underscoring a broad-based advance. The rally was fueled by a combination of easing geopolitical tensions, a retreat in oil prices and bond yields, and continued enthusiasm around artificial intelligence and a landmark IPO filing.

Geopolitical and Macro Catalysts

The week began on shaky ground as oil prices traded above $100 a barrel and the 30-year Treasury yield hit its highest level since 2007, triggering a three-session losing streak for the S&P 500. However, the mood shifted dramatically on Wednesday after President Donald Trump announced that the U.S. was in the "final stages" of peace talks with Iran. Oil prices and bond yields retreated, sparking a rally that carried through the rest of the week. The S&P 500 has now advanced for eight consecutive weeks since its Iran wartime bottom on March 30, marking its longest winning streak since late 2023.

Tech and AI Momentum

Technology stocks continued to lead the charge. Nvidia, the poster child of the AI boom, reported a strong quarter on Wednesday night, but its stock failed to rally—a sign that even blockbuster results may already be priced in. Nevertheless, the broader AI trade remained robust. Cybersecurity stocks, including CrowdStrike, staged a remarkable comeback, adding to the tech sector's gains. The Nasdaq's 0.5% rise for the week reflected resilient investor appetite for growth names.

In another major development, SpaceX filed for its initial public offering on Wednesday, expected to be the largest in history. The filing injected fresh optimism into the market, particularly among growth and innovation-focused investors. The Dow's 2.1% jump highlighted a rotation into cyclical and industrial names, suggesting confidence in the economic outlook.

Historical Caution

Despite the rally's vigor, some strategists urge caution. SimCorp's Melissa Brown points to historical data from Stocks, Bonds, Bills and Inflation (SBBI) showing that the market rarely delivers four consecutive years of strong returns. After annualized gains of 26%, 25%, and about 18% in 2023, 2024, and 2025 respectively, the S&P 500 has risen only 8% year-to-date. Brown notes that the fourth year following a three-year annualized return of 20% or more has averaged just 3.9%, well below the long-term average of 11.8%. "Things just can't grow forever," she said. "We're clearly closer to the end of the rally than the beginning."

However, Brown acknowledges that the AI boom could defy historical patterns. If AI-related stocks continue to drive the market higher, 2026 could still deliver low-double-digit returns. But she warns that the probability of another strong year in 2027 would be even lower if 2026 meets expectations.
