Market Recap: Tuesday, May 12 — Hot April Inflation and Surging Oil Push Tech Lower
Hotter-than-expected April inflation and surging oil prices weighed on technology stocks Tuesday, while the Dow held modest gains.
Market Overview
Stocks finished mixed Tuesday after a hotter-than-expected April inflation reading and another leg higher in oil prices pressured technology shares. The Dow eked out a small gain as defensive names held up, while the Nasdaq slipped under the weight of a tech sell-off and the S&P 500 ended just below its previous close.
Index Performance
| Index | Close | Change |
|---|---|---|
| S&P 500 (SPY) | $738.19 | -0.14% |
| NASDAQ (QQQ) | $707.22 | -0.86% |
| Dow Jones (DIA) | $497.88 | +0.14% |
The split is a classic inflation-day pattern: the tech-heavy Nasdaq carried the brunt of the move, while the Dow's mix of energy, industrials, and consumer staples held firmer. Investors trimmed exposure to the names that had led the recent rally and leaned toward sectors that tend to weather higher prices better.
What Drove the Market Today
The big story was the April Consumer Price Index, released before the open. Inflation came in at 3.8% year over year, a touch above the 3.7% economists were looking for and the highest annual reading since May 2023. Monthly prices rose 0.6%, with energy doing most of the heavy lifting — energy prices jumped 3.8% in April and accounted for more than 40% of the headline increase.
Oil was the second piece of the puzzle. West Texas Intermediate crude jumped more than 4% on the day to settle above $102 a barrel, with traders still focused on supply disruptions tied to the ongoing Iran conflict. Higher oil feeds straight into gasoline prices and tends to act like a tax on consumer spending, which makes the Fed's job of cooling inflation harder.
For markets, the takeaway was simple: hotter inflation plus expensive oil dims the odds of near-term interest rate cuts. That's why high-multiple growth stocks — especially chipmakers — took the biggest hit. Investors are also looking ahead to Nvidia's earnings on May 20, which is keeping volatility elevated across the semiconductor space.
Today's Top Movers
Gainers
- AMBQ (Ambiq Micro) +45% — Q1 revenue surged 59% year over year on demand for the company's edge-AI chips, and the company beat earnings estimates. Management pointed to triple-digit growth potential in medical, industrial, and smart-home categories.
- VPG (Vishay Precision Group) +28% — Posted strong Q1 results with bookings of $102 million, up 26% sequentially. Demand from AI infrastructure and defense customers led the way.
- PACS Group +29% — Shares rallied alongside an earnings update, though no single dominant catalyst stood out in the news flow.
Losers
- PSIX (Power Solutions International) -39% — A sharp Q1 earnings miss did the damage. Adjusted earnings of $0.36 came in well below the $0.74 consensus, revenue fell 5% year over year, and management withheld full-year guidance. Several securities class-action lawsuits were also disclosed.
- NVTX -30% and DXYZ -25% — Both names saw heavy selling on the day; the moves came without a clear single catalyst in mainstream financial reporting.
- KORU -23% — Another sharp drop without an obvious public catalyst.
Most Active Stocks
Volume leaders tell their own story today. SOXS, a leveraged ETF that profits when semiconductors fall, traded more than 500 million shares — a sign investors were positioning for further chip-sector weakness. Intel (INTC) changed hands more than 170 million times as the stock pulled back roughly 4.6% following its huge year-to-date rally and an HSBC downgrade. NVIDIA (NVDA) stayed active ahead of its May 20 earnings report.
What This Means for You
Days like this are a useful reminder that inflation data still moves markets, and that interest-rate expectations are tightly linked to oil and energy prices. When the Nasdaq drops but the Dow holds steady, it usually signals a rotation rather than broad fear — investors are repositioning rather than heading for the exits. For long-term investors, the bigger lesson is that single data points rarely change the trajectory; the trend over months matters more than any one CPI print.
