S&P 500 Slides as Inflation Surprises and Chip Stocks Tumble

CNBC reported Tuesday that U.S. equities retreated from record territory after April inflation came in hotter than expected, sending investors into risk-off mode alongside a sharp decline in semiconductor shares.

The S&P 500 closed down 0.7% on the session. The Nasdaq Composite shed 1.6%. The Dow Jones Industrial Average dipped roughly 27 points, or 0.1%.

April Inflation Surprises to the Upside

The Bureau of Labor Statistics reported that the consumer price index rose 0.6% in April on a monthly basis. On an annual basis, prices climbed 3.8%, exceeding the 3.7% gain economists polled by Dow Jones had anticipated. That annual reading is the highest since May 2023.

Senior portfolio manager Thomas Martin of Globalt Investments told CNBC the data reflects a slow but persistent upward grind. Martin warned that prolonged Middle East conflict will keep feeding price pressures, and that elevated energy costs will increasingly squeeze household budgets.

Oil Prices Add Fuel to Inflation Anxiety

Crude markets amplified the inflation concern Tuesday. West Texas Intermediate futures surged roughly 3%, pushing above $101 per barrel. Brent crude crossed $107 per barrel after similar gains. Both benchmarks extended Monday’s advance following remarks by President Donald Trump, who described the month-old U.S.-Iran ceasefire as fragile and said negotiations remained stalled. Iran’s latest counterproposal reportedly includes demands for war reparations, full control over the Strait of Hormuz, and the release of frozen assets alongside full sanctions relief. No deal has been struck.

Background: A Semiconductor Rally Hits a Wall

Last week’s tech momentum had been striking. Micron Technology surged more than 37% across five sessions, with chipmakers broadly powering both the S&P 500 and the Nasdaq to fresh records as investors expanded their artificial intelligence bets beyond Nvidia. Monday saw Micron add another 6% before Tuesday’s reversal wiped out a double-digit percentage of those gains.

The broader chip sector retreated sharply. Qualcomm dropped roughly 13% in what CNBC noted was potentially its worst single-day performance since 2020. Advanced Micro Devices fell approximately 6%. Intel shed around 8%. The iShares Semiconductor ETF tracking the sector declined nearly 5%.

Markets Weigh Competing Pressures

Investors now face a complicated macro backdrop. Strong corporate earnings from several industrial names offered some cushion. Uniform supplier Vestis surged more than 30% after beating quarterly estimates. Automation firm Zebra Technologies popped 17% on earnings that topped analyst expectations. Precision instruments maker Ralliant gained 14% on a similar beat. Yet those idiosyncratic wins could not offset the sector-wide drag from energy and inflation concerns.
