The Chip Rout Came Back and Oil Spiked. The Dow Slipped From a Record.

Monday’s calm didn’t last. The AI/semiconductor selloff resumed Tuesday — triggered by Samsung’s earnings miss and a report that China’s DeepSeek is building its own AI chip — while oil jumped more than 5% on renewed attacks near the Strait of Hormuz. The Dow, which hit a new all-time intraday high early, reversed to close down 131 points; the Nasdaq fell 1.16% as chips again led losses. It was a return to the late-June pattern: the AI trade wobbling on valuation and competition fears, and the market rotating out of tech — this time with a geopolitical oil shock layered on top.

💾 The chip rout, part two — Samsung and DeepSeek

The semiconductor complex was the epicenter again:

• Samsung posted a 19-fold jump in Q2 profit — but came up short of the most optimistic estimates, and AI-memory demand and valuation worries spooked investors. Record results, sold anyway — the familiar AI-era pattern
• A Reuters report that China’s DeepSeek is developing its own AI inference chip (to cut Nvidia dependence) added a competitive question for AI chip suppliers
• The Philadelphia Semiconductor Index fell ~4.6%; Micron -4.7%, with KLA, Marvell, Broadcom and AMD all lower
• South Korea’s Kospi fell ~4.9% on the Samsung print — again the overnight barometer for US chip sentiment
• FBB Capital’s Mike Bailey summed it up: expectations are sky-high and fundamentals are struggling to meet them — the core tension in the AI trade

🛢️ Oil spiked 5% — the Hormuz risk is back

The fragile ceasefire showed its cracks:

• Brent jumped 5%+ above $76; WTI 5%+ above $72 — after reported attacks on commercial vessels near the Strait of Hormuz
• The US-led maritime coalition raised its shipping threat assessment to “severe” for the strait, which handles ~20% of the world’s oil traffic
• The attacks underscore the fragility of the ceasefire as the US and Iran negotiate a permanent end to the war
• A fresh complication for the “inflation peak is in” thesis: the disinflation trade has leaned on falling oil, and a sustained Hormuz risk premium pushes the other way

📉 The reversal — a record high, then red

The tape echoed recent whipsaws:

• Dow: -0.25% → 52,925.15 (-130.76) — after a new intraday record early in the session
• S&P 500: -0.45% → 7,503.85
• Nasdaq: -1.16% → 25,818.69 (chips the drag)
• Europe sold off harder: DAX -1.37%, FTSE MIB -0.95%, CAC -0.51% (FTSE 100 bucked it, +0.13%)
• SpaceX joined the Nasdaq-100 — its first session as a member
• One bright spot: Crinetics nearly doubled after Vertex agreed to acquire it for ~$10B ($85/share)

• Looking ahead: June CPI lands Tue Jul 14 — the last major inflation read before the July 28–29 FOMC

🧠 Bottom line

The AI-trade anxiety that defined late June came roaring back after a one-day reprieve. Samsung’s record-but-not-enough quarter is the same story we’ve watched all summer — the bar for AI names is so high that even blockbuster results disappoint — and the DeepSeek chip report adds a competitive question to the valuation one. That the Dow could hit a fresh intraday record and still close red tells you the rotation is alive: money is still leaving crowded tech, now without a clear cyclical winner to catch it when oil is also spiking.

The oil move is the new variable. A renewed Hormuz risk premium could complicate the disinflation narrative if elevated prices persist — the story that’s underpinned the soft-landing trade — and it lands right before Wednesday’s Fed minutes and next week’s CPI. For a market that rallied on the idea the inflation peak was in, a 5% oil jump on war headlines is a pointed reminder of how fragile that assumption is.

The chip rout returned, oil spiked on Hormuz, and the Dow slipped from a record. Now the Fed’s minutes land into a nervier tape.
