Quick Read

Intel, AMD, and Applied Materials shares fell 4% after SK Hynix’s profit estimate missed consensus by 8%, triggering a 15% plunge and a brief KOSPI trading halt.

Lam Research dropped 5% and the SOXX ETF fell 4% as U.S.-Iran fighting over the Strait of Hormuz spiked WTI crude oil to $74, amplifying pressure on chip margins.

Intel’s Q2 2026 earnings, due this month, could reset the memory-versus-AI-compute debate for the sector, with Polymarket pricing a 67% chance of a beat.

Shares of Intel (NASDAQ:INTC) are down 4% to $104.97 in Monday morning trading, while Advanced Micro Devices (NASDAQ:AMD) stock is off 4% to $533.58 and Applied Materials (NASDAQ:AMAT) shares are down 4% to $581. The selling started at the open and leveled out into mid-morning.

The move caps a blistering run for the chip complex. Intel stock is up 182% year to date (YTD), AMD shares are up 147%, and Applied Materials shares have gained 126%. With the NASDAQ 100 down 1.28% on the session, the broader tech tape has weakened alongside semis, amplifying the profit-taking impulse.

Memory Rout and Oil Spike Hit Chip Complex

The immediate trigger came from Asia. South Korean brokerage KIS published a Q2 2026 profit estimate for SK Hynix that landed 8% below consensus, citing slow HBM4 shipments and heavy reliance on high-bandwidth memory. SK Hynix shares fell 15% on the Korean exchange, dragging Samsung and the KOSPI, which slid 9% and triggered a brief trading halt.

The read-through was swift. Applied Materials, which counts SK Hynix as a key HBM and DRAM equipment customer, absorbed the biggest hit in the group. NVIDIA (NASDAQ:NVDA) stock and Broadcom (NASDAQ:AVGO) stock each declined 2% as memory-cycle worries rippled across the AI hardware complex.

July 16 is the Final Day to Tap Into the Lithium Boom (sponsor)
General Motors, POSCO, and 50,000+ everyday investors have already backed lithium producer EnergyX.

Here’s why you should do the same before their July 16 investment deadline: lithium prices are up 75% this year, with demand projected to grow a staggering 5X by 2040.

With tech that can recover up to 3X more lithium than traditional methods, EnergyX is preparing to unlock up to 15M+ tons. Become a private-stage EnergyX investor before the July 16 deadline.

Adding to the pressure, renewed U.S.-Iran fighting over the Strait of Hormuz sent crude sharply higher. WTI crude oil is up 3.64% over the past 24 hours to $74.01 a barrel, which is a concern as rising energy costs pressure semiconductor margins and stoke broader macro risk-off flows.

Story Continues

Sector Proxy and Equipment Names Under Pressure

The iShares Semiconductor ETF (NASDAQ:SOXX) is down 4% to $555.93, mirroring the sector drawdown. The fund is concentrated in the exact names caught in today’s selloff, so its beta to memory and AI-hardware sentiment is elevated. It does not use leverage, but concentration risk is meaningful.

Lam Research (NASDAQ:LRCX) stock, another equipment maker with heavy memory exposure, is down 5% to $332.95. Lam’s South Korea revenue of $1.34 billion underscores the direct SK Hynix read-through for the picks-and-shovels equipment group.

Bull and Bear Case on Intel

For Intel as the primary mover, the bull case rests on an AI-driven chip cycle that has already delivered. Intel’s Q1 2026 revenue rose 7% year over year (YoY) to $13.58 billion, and the Data Center and AI segment grew 22% YoY under CEO Lip-Bu Tan. Polymarket contracts assign a 67% probability to Intel topping its next quarterly report.

The bear case is what Monday is pricing in. Memory-cycle risk flagged by the SK Hynix estimate, oil-driven macro pressure, and rich valuations after Intel’s 361% one-year gain all argue for caution. Investors should consider keeping their position sizes modest given the daily volatility on names that have tripled or more from year-ago levels.

What to Watch

Watch for whether WTI crude oil stabilizes below $75 and whether SK Hynix finds a floor overnight in Seoul. Any further escalation around the Strait of Hormuz could keep the risk premium in oil elevated, extending pressure on the chip complex.

The next catalyst is earnings. Intel’s Q2 2026 earnings report is due later this month, and Polymarket contracts on the release expire July 23. That report may reset the memory-versus-AI-compute debate for the whole group, and investors can watch it closely for margin and Data Center guidance.

Meet America’s Newest $1b Unicorn (Sponsor)

A US startup just passed a $1 billion private valuation, joining billion-dollar private companies like OpenAI and ByteDance. Unlike those other unicorns, you can invest in EnergyX right now; but only until July 16.

Over 50,000 people already have, along with global giants like General Motors and POSCO.

Here’s why there’s so much interest: EnergyX’s patented tech can recover up to 3X more lithium than traditional methods. That’s a big deal, as demand for lithium is expected to 5X current production levels by 2040. Become an early-stage EnergyX shareholder before the 7/16 investment deadline.
