Wall Street closed on a high note Wednesday, with the S&P 500 and Nasdaq Composite both notching record finishes. The rally was fueled by a robust outlook from Advanced Micro Devices (AMD), which sent AI-linked stocks surging, and a sharp decline in oil prices that eased inflationary concerns.
The S&P 500 advanced 1.46% to 7,365.09, while the Nasdaq added 2.03% to close at 25,838.94. The Dow Jones Industrial Average also rose, gaining 1.24% to end at 49,910.59. Nine of the 11 S&P 500 sectors posted gains, led by industrials and information technology. Trading volume on U.S. exchanges exceeded recent averages, reflecting strong investor participation.
AMD and Chip Stocks Lead the Charge
AMD shares soared nearly 19% to a record close after the company issued an upbeat revenue forecast, citing surging demand for data-center chips. The Philadelphia Semiconductor Index (SOX) also climbed 4.5%, pushing its year-to-date gain to 62%. Intel (INTC) rose 4.5% in sympathy. Analysts noted that AMD's success is not solely about competing with Nvidia (NVDA); it represents a broader opportunity as AI demand extends into central processing units (CPUs).
"Success invites competition," said Michael O'Rourke, chief market strategist at JonesTrading. Matt Britzman, senior equity analyst at Hargreaves Lansdown, described AMD as a "broader compute opportunity" now that AI demand is reaching beyond graphics processors and into core server chips.
After the bell, Arm Holdings (ARM) provided another AI sentiment check. The chip designer forecast first-quarter revenue of $1.26 billion, just above LSEG estimates, but its stock initially jumped 12% before reversing to a 5.49% decline as executives highlighted supply constraints on a new chip and analysts focused on cost impacts of scaling chipmaking.
Oil Prices Tumble on Iran Deal Hopes
Brent crude oil futures plunged 7.83% to close at $101.27 a barrel, while U.S. crude fell approximately 7% to $95.08. The drop came as optimism grew over a potential U.S.-Iran agreement, which could increase global oil supply and ease geopolitical tensions. This decline in energy prices provided a tailwind for equities by reducing inflationary pressure, even as Middle East turmoil remains a risk.
Earnings Season Delivers Strong Results
First-quarter earnings continued to impress. S&P 500 companies are on track for 28.2% profit growth, the best performance since late 2021, according to LSEG data. "Earnings fueled the rally as worst-case Iran-war talk faded," said Chris Fasciano, chief market strategist at Commonwealth Financial Network. Binky Chadha of Deutsche Bank noted that excluding special items, this profit growth is "arguably the strongest in two decades."
Disney (DIS) shares climbed after CEO Josh D'Amaro outlined a strategy focused on streaming, sports, parks, and cruises, beating quarterly targets. Uber (UBER) also advanced after its second-quarter gross bookings outlook topped Wall Street estimates.
AI Infrastructure and Data Center Deals
AI infrastructure stocks remained in focus. Hut 8 (HUT) announced a $9.8 billion, 15-year lease for its Beacon Point data center in Texas, a facility designed for Nvidia's latest hardware, with support from American Electric Power (AEP), Vertiv (VRT), and Jacobs (J). Hut 8 CEO Asher Genoot described the deal as backed by a "high-investment-grade counterparty."
Fed Officials Caution on Inflation
Federal Reserve officials struck a cautious tone. Chicago Fed President Austan Goolsbee said he is not yet calling stagflation but described the current situation as "just an inflationary shock." St. Louis Fed President Alberto Musalem indicated that interest rates may need to stay at current levels "for some time" and could even rise further.
Labor Market Data
The labor market showed modest improvement. ADP reported that U.S. private payrolls increased by 109,000 in April, the strongest gain in 15 months. However, economists flagged risks from oil prices, global conflict, and policy uncertainty, keeping the outlook shaky ahead of Friday's official payrolls report.
