- The Nasdaq fell 1.16% to 25,819 as a DeepSeek own-chip report and Samsung's cautious outlook sank semiconductors; Micron dropped 4.7%.
- Iran struck a Qatari LNG tanker in the Strait of Hormuz; oil firmed toward $69 and the US pulled Iran's sanctions relief.
- Defensives absorbed the rotation — staples +2.1%, energy +2.0%, health care +1.6% — while the 10-year yield rose to a two-week-high 4.50%.
Indexes
The rally that carried the Dow above 53,000 on Monday met its counterweight on Tuesday, and it came from the same corner that produced the gains: semiconductors. A Reuters report that China's DeepSeek is designing its own inference chip, arriving on top of cautious memory commentary from Samsung, pushed investors to question how durable the year's AI-hardware boom really is, and the selling stayed narrow, confined to the chip complex. Micron fell 4.7%, the VanEck Semiconductor ETF dropped more than 3%, and Nvidia, Broadcom and Marvell all closed lower, enough to pull the Nasdaq Composite down 1.16% to 25,818.69. The rest of the market barely flinched: investors rotated into health care, consumer staples and energy rather than selling stocks outright, so the S&P 500 gave up just 0.45% to 7,503.85 and the Dow, higher by triple digits at its intraday peak, slipped only 0.25% to 52,925.15 after briefly setting a fresh record early in the session. The clearest read on the day was the roughly one-point gap between the Nasdaq and the Dow, the signature of a chip repricing and not a broad growth scare. "Expectations are up, and fundamentals are struggling to meet these sky-high demands," said Mike Bailey, director of research at FBB Capital Partners.
| Index | Close | % Chg | Day Range | Note |
|---|---|---|---|---|
| S&P 500 | 7,503.85 | -0.45% | 7,495–7,542 | Chips outweigh a broad bid |
| Nasdaq Composite | 25,818.69 | -1.16% | 25,780–26,095 | Semiconductors lead lower |
| Dow Jones | 52,925.15 | -0.25% | 52,870–53,180 | Reversed off an intraday record |

Sector Heat Map
The map flipped cleanly from Monday's offense to defense, with only the chip-heavy corner of technology in the red.
| Sector (ETF) | % Chg | Note |
|---|---|---|
| Consumer Staples (XLP) | +2.1% | Walmart leads the safety bid |
| Energy (XLE) | +2.0% | Crude firms on Hormuz risk |
| Health Care (XLV) | +1.6% | Eli Lilly out front |
| Utilities (XLU) | +0.9% | |
| Materials (XLB) | +0.4% | |
| Financials (XLF) | +0.3% | |
| Industrials (XLI) | +0.3% | |
| Real Estate (XLRE) | -0.2% | Higher yields weigh |
| Consumer Disc. (XLY) | -0.5% | |
| Communication Svcs (XLC) | -0.6% | |
| Technology (XLK) | -2.8% | Memory and chip gear drag |
Nine of eleven sectors rose; the two that fell were the ones most levered to the AI-hardware trade, which is the whole story of the session in one line.
In the News
Rates, FX, Commodities
The bond market did not play along with the equity wobble. Yields rose rather than fell, because the Strait of Hormuz strike lifted oil and revived a whiff of inflation risk, and an energy-driven move in rates outweighs the usual flight to safety.
| Rates & Vol | Level | Note |
|---|---|---|
| 2-Year Treasury | 4.12% | Little moved, mid-range |
| 10-Year Treasury | 4.50% | Two-week high on oil |
| 30-Year Treasury | 4.97% | |
| 2s10s spread | +38 bp | Positive slope holds |
| VIX | 15.6 | Barely firmer despite the drop |
| FX & Commodities | Level | Note |
|---|---|---|
| Dollar Index (DXY) | 100.9 | Still pinned below 101 |
| WTI Crude | $69.10 | Reverses off a four-month low |
| Brent Crude | $72.20 | One-week high |
| Gold | $4,148 | Eases as yields climb |
| Nat Gas | $3.25 |
Technicals
The S&P 500 closed about 0.4% under Monday's record but stayed comfortably above its rising 20- and 50-day averages; first support sits near 7,470, with the 7,537 record the level to reclaim. The Nasdaq Composite fell back toward 25,800, still inside the June breakout zone that has framed the advance. On rates, the 10-year at 4.50% is pressing the top of its two-week range, and a close above roughly 4.55% would put the spring highs near 4.65% back in play; the 2-year at 4.12% remains in the middle of its band. The day's sharpest breakdown was Micron, which lost Monday's low and slipped under its 20-day on heavy volume, while Broadcom handed back part of the gap it opened on the Apple deal. Against that, Eli Lilly cleared the top of its June range as the defensive bid found it, a rare upside breakout on a red day.
Top Movers
Gainers
Eli Lilly (LLY) added about 3%, the standout among the defensive names investors rotated into. With no company-specific news, the move was flow: on a day the market wanted earnings it could count on, large-cap pharma was the obvious harbor, and Merck and AbbVie firmed alongside it.
Walmart (WMT) rose after saying it would cut prices on staples such as ground beef and Coca-Cola, a scale play aimed at winning budget-conscious traffic. The read for the group is competitive pressure on Target and the dollar stores, which cannot match Walmart's buying power on food.
Losers
Micron (MU) fell 4.7%, the session's marquee decliner and the clearest expression of the AI-hardware wobble. The trigger was twofold: a Reuters report that DeepSeek is designing its own inference chip, and Samsung's caution on memory pricing even as it posted a record quarterly profit. Neither changes the near-term supply picture for high-bandwidth memory, where Micron remains sold out, but both feed the harder question of whether the market has paid too much for a demand curve it is now second-guessing. The stock is still up sharply on the year, which is exactly why a report like this can shake it. SanDisk, Marvell and the Samsung ADRs moved in sympathy.
Nvidia (NVDA) slipped roughly 1% on the DeepSeek report. The threat is to inference demand rather than to the training clusters that anchor Nvidia's backlog, which is why the reaction was measured relative to the headline.
Broadcom (AVGO) gave back a piece of Monday's Apple-deal pop, a natural exhale after a sharp two-day run.
Marvell (MRVL) fell with the group on no fresh news of its own.
Key Macro Data Today
The data calendar was quiet, with only May consumer credit of note and no market-moving surprise. The real event is Wednesday afternoon's June FOMC minutes.
Notable Earnings This Session
Pre-Open
Nothing crossed before the bell worth flagging; the S&P 500 calendar was bare.
Post-Close
After-hours proved just as thin. The second-quarter reporting season opens next week, led by the big banks.
Drivers
1. The June FOMC minutes land Wednesday at 2 p.m. ET, the first paper trail from Kevin Warsh's debut meeting as Fed chair, a gathering that ended in a pause. The market will read them for how divided the committee was and whether the energy-driven inflation worry that lifted yields on Tuesday has real support inside the room. One caveat frames the whole exercise: the meeting predates Friday's soft payrolls report, so the minutes reflect a labor picture the Fed had not yet seen.
2. Oil holds the other half of the week's risk. Whether Tuesday's tanker strike proves a one-off or the opening of a broader disruption in the Gulf will set the tone; Brent near $72 and WTI near $69 already carry a fresh risk premium, and a second attack would widen it fast.
3. The chip selling will not resolve in a vacuum. The next hard read arrives Tuesday, July 14, when JPMorgan and the big banks open second-quarter earnings season and hand the market a fresh set of fundamentals to price against.
