S&P 500 Reaches Record Highs as Market Hits Historic Nine-Week Winning Streak
The stock market surged to record levels as the S&P 500 reached a 20% gain from its war-driven lows, notching its longest weekly winning streak since 2023. Market momentum was buoyed by optimism over Iran ceasefire negotiations and strong AI-driven corporate earnings.
Record Rally Amid Geopolitical Optimism
Hopes that a ceasefire deal could pave the way for an end to the Iran conflict drove stocks toward a historic streak of weekly gains, with the market also buoyed by the artificial-intelligence trade. A roughly 20% surge in the S&P 500 from war-driven lows left the index on track for its ninth straight weekly advance, the longest stretch since 2023.
Market Momentum and Sector Strength
Dell Technologies Inc. soared 33% on a solid outlook fueled by demand for AI servers. The semiconductor sector has been particularly robust, with shares of Micron Technology jumping 19% and topping $1 trillion in market capitalization amid bullishness among analysts on the Street. UBS said the stock should rerate higher as investors better understand the impact of artificial intelligence to the memory industry. Micron shares have soared more than 200% in 2026 and more than 800% over the last 12 months.
Economic Headwinds Remain
Despite the rally, underlying economic challenges persist. The personal consumption expenditures (PCE) price index — the Federal Reserve's preferred inflation gauge — rose 3.8% year over year last month, up from 3.5% in March and 2.8% in February. U.S. consumer confidence moved lower in May, a survey from The Conference Board showed Tuesday, citing escalating inflationary impacts due to the Middle East conflict. The consumer confidence index dropped 0.7 to 93.1 from an upwardly revised 93.8 in April.
What to Watch
Market strategists caution that consolidation may be needed after the recent surge. The continued war in Iran has hurt global supply chains to the point that experts are now saying gas prices won't return to their pre-war levels anytime soon, likely worsening conditions for lower-income consumers. Energy prices remain a critical variable for both inflation and market performance going forward.
