Wall Street suffered a broad selloff on Wednesday, with the S&P 500 falling 1.56%, the Nasdaq Composite dropping 1.99%, and the Dow Jones Industrial Average losing 1.67%, as a sharp decline in artificial intelligence stocks and renewed inflationary pressures from rising oil prices rattled investors.
The selloff was led by a steep plunge in Super Micro Computer (SMCI), which tumbled over 20% after the company announced a $7 billion equity and equity-linked financing plan. The move, aimed at funding component purchases for roughly $39 billion in AI-server orders from more than 20 customers, sparked dilution fears among shareholders. Super Micro cautioned that those orders are non-binding and could be delayed or cancelled, adding to investor unease.
The Philadelphia semiconductor index fell 2.6%, with Nvidia (NVDA) and Broadcom (AVGO) among the biggest drags on the S&P 500. The tech-heavy Nasdaq bore the brunt of the losses as investors rotated out of high-flying AI names that have powered much of this year's rally.
Inflation Data and Oil Prices Add Pressure
Markets also grappled with a hotter-than-expected Consumer Price Index (CPI) report from the Labor Department. Headline CPI surged 0.5% in May and rose 4.2% year over year, driven largely by energy costs. Gasoline prices jumped 7% in May and are up 40.5% over the past 12 months. Core CPI, which excludes food and energy, increased 0.2% for the month and 2.9% on an annual basis.
Oil prices climbed further on geopolitical tensions, with Brent crude gaining 1.8% to close at $93.10 a barrel, while U.S. crude settled at $90.03, up 2%. President Donald Trump's warning to hit Iran "very hard" pushed prices higher, along with a larger-than-expected 7.2 million-barrel drop in U.S. crude inventories.
Market Implications and Sector Rotation
The combination of rising oil prices and sticky inflation has led traders to price in at least one 25-basis-point interest rate increase by year-end, according to Reuters. Tom Hainlin, investment strategist at U.S. Bank Wealth Management, noted that investors are "pricing in maybe a higher interest rate" after the fresh economic data, and many are uneasy about the conflict dragging through the summer.
Defensive sectors such as health care, real estate, and consumer staples gained as investors shifted away from growth stocks. Meanwhile, trucking stocks including XPO (XPO), J.B. Hunt (JBHT), and Old Dominion (ODFL) fell after Amazon (AMZN) entered the less-than-truckload freight market, raising competition concerns.
Looking Ahead
The selloff raises questions about the sustainability of the AI-driven rally and the broader market's reliance on easing inflation. If oil prices remain elevated, headline CPI could stay stubborn, forcing the Federal Reserve to maintain higher interest rates. A further decline in AI stocks would hit indexes hard, as the same mega-cap tech names that led gains can reverse quickly.
Investors are now focused on Oracle's (ORCL) earnings report after the bell for the next read on AI infrastructure demand, and the Producer Price Index (PPI) due on June 11, which will reveal whether inflation is building in business costs before reaching consumers.
