Indexes

A memory-chip scare that began in South Korea swept through the technology sector on Tuesday, dragging the Nasdaq down more than 2% while the rest of the market barely budged. The S&P 500 fell 1.44% to 7,365.46 and the Nasdaq 100 lost 3.29% to 29,347.27, but the Dow finished within a whisker of where it started and the Russell 2000 gave back less than a percent. It was Monday's rotation run in reverse: this time the chips took the damage and the steadier corners of the market held.

The three-point gap between the Nasdaq 100 and the Dow told the story: that kind of spread between the tech-heavy index and the blue chips opens only when the selling is trained on one part of the market. Small caps surrendered Monday's milestone, the Russell closing back below the 3,000 line it had cleared for the first time a day earlier, though its modest loss looked tame against the wreckage in chips.

Sector Heat Map

Money fled technology and crowded into nearly everything else; the steadier groups of staples, health care, real estate and utilities all finished firmly higher.

Staples led at +1.87%, with health care, real estate and utilities close behind, each up more than three-quarters of a percent, while technology alone dropped 4.14%. That was the precise opposite of the day before, when technology held and the megacap platforms cracked. Investors did not flee stocks so much as relocate within them.

In the News

Drivers

1. Micron headlines Wednesday's close. The memory maker reports fiscal third-quarter results one day after losing 13% in the Seoul-driven chip scare, and the commentary on high-bandwidth memory and DRAM pricing is what will move it: confirmation that the AI-memory cycle is still tightening would reverse much of Tuesday's drop, while any hint that supply is catching up to demand would validate the fear that sank it. Options price a move of about 17% in either direction, which leaves the report to set the tone for the entire chip group, not just one stock.
2. Whether the chip selling steadies or spreads. Tuesday's damage stayed concentrated in memory and AI silicon while the rest of the market held, so the read tomorrow is breadth. If Nvidia, Broadcom and the equipment names stabilize, the session looks like a single repricing rather than the start of something larger; another leg lower would be far harder to contain, since technology still carries the heaviest weight in the S&P 500.
3. Thursday brings the May PCE figures, the inflation gauge the Fed watches most. Consensus looks for a 0.5% monthly gain and a core rate near 3.4%, and after Bank of America's call for three rate hikes pushed September odds to about 68%, a soft surprise would land harder than the firm number most investors anticipate.

S&P 500 ETF (SPY), daily: a 1.4% pullback that lost the 20-day average but held above the rising 50-day.

Nvidia (NVDA), daily: the AI leader fell with the group, off 3.8% to $200.04 on the memory scare.

Johnson & Johnson (JNJ), daily: health care drew the defensive bid, lifting the shares 3.4% to a one-month high.

FedEx (FDX), daily: the shares closed at their lowest since January, then slipped further on the after-hours report.

Rates, FX, Commodities

A flight to safety pulled Treasury yields lower even on the day Bank of America told clients to brace for three rate increases, the bond market reading the equity slide as the more pressing signal.

Measured against the long end, the front of the curve slipped a little faster, pushing the spread between two- and ten-year yields out to about 30 basis points and tilting it steeper ahead of Thursday's reading.

The dollar firmed for a second session and pressed on gold, which slid to $4,127.00 even with equities falling, a sign the stronger greenback and the louder rate-hike talk outweighed the usual hunt for a haven. Copper fell 2.42% on the same growth worry that hit the cyclicals. Each commodity quote here was captured after Tuesday's settle, not inherited from the prior session.

Technicals

At 7,365.46, the S&P 500 finished beneath its 20-day line, now near 7,470, and about 50 points above the rising 50-day at 7,316, the first real support on the chart; a close under it would open room back toward the early-June breakout. The Nasdaq 100 took the heavier structural damage, slicing through both its 20- and 50-day lines in a single session and landing near the floor of the month-long range it had been pressing against from above. On the rate side, the ten-year's pullback to 4.49% eased it off the top of a three-week band, with a sustained move above 4.55% the level that would put fresh pressure on equities. The day's most violent move was Micron's, shown in the hourly chart below.

Breakouts & Breakdowns

Breakouts

Johnson & Johnson (JNJ) rose 3.4% to $239.08, the day's defensive leader, clearing its early-June highs near $238 and putting the $244 area next as money rotated into health care.

Walmart (WMT) gained 2.0% to $119.42, pressing the $120 shelf that has capped it since spring; a close through that level would mark a fresh high for the staples heavyweight.

Breakdowns

Taiwan Semiconductor (TSM) fell 6.7% to $436.39, erasing last week's record breakout and dropping back under the $462 level it had just cleared, with the 50-day near $430 the next support.

Advanced Micro Devices (AMD) lost 4.9% to $519.85, giving up both its 20- and 50-day averages in the chip rout; the May base near $500 is the next floor down.

Top Movers

The split was clean: anything tied to memory or AI silicon was sold hard, while the megacap platforms that led Monday's decline and the classic defensives drew the buyers.

Gainers

Microsoft (MSFT) climbed 1.5% to $373.94, clawing back part of Monday's slide as buyers returned to the megacap platforms that had led last week's selling. With the chipmakers suddenly in the crosshairs, the software and cloud giants briefly became the place to hide.

Amazon (AMZN) added 0.5% to $234.11 on the same rotation back toward the platforms.

Losers

Micron (MU) tumbled 13% to $1,051.77, the worst day among large-cap chipmakers in more than a year and a brutal setup a session before its own fiscal third-quarter results. The trigger came from Seoul: a report that SK Hynix may slow its AI-memory expansion and lean back toward conventional chips cracked the comfortable assumption that memory pricing only travels one way. Bank of America's call for three more rate hikes added a second weight on a name that had run hard all spring. The drop wipes out more than two weeks of gains and sets up a Wednesday report that options already price for a move of about 17%.

Marvell (MRVL) dropped 8.1% to $279.04, the hardest hit of the AI-silicon designers as the memory fear bled into anything leveraged to data-center demand. Its custom-chip franchise has been a crowded favorite, which left it more exposed once the group turned.

Carnival (CCL) fell 4.7% to $28.72 even after a clear earnings beat, posting record quarterly revenue of $6.7 billion and adjusted earnings of $0.41 a share against the $0.34 expected. The selling followed a cautious note from Bernstein flagging a trimmed full-year yield outlook and softer booking commentary tied to geopolitical tension. With the stock up sharply this year, a record quarter was no longer enough.

FedEx (FDX) slipped 3.5% to $317.24 in the regular session, its lowest close since January, then eased about 3% more after hours despite a strong report. Adjusted earnings of $6.31 beat the $5.96 estimate and revenue of $25.0 billion grew almost 13%, with management guiding fiscal 2027 adjusted earnings to a range of $16.90 to $18.10. These were its first results since spinning the freight arm off on June 1, and the hesitation owed less to the quarter than to a slower pace of revenue growth ahead.

Key Macro Data Today

The US calendar was light, leaving Europe's flash business surveys as the day's notable release and Thursday's inflation reading as the week's real event.

The eurozone surveys came in a shade better than feared and steadied sentiment in Europe early, though they were no match for the chip story out of Asia. At home, attention is fixed on Thursday's PCE inflation report, the price measure the central bank leans on most, where consensus looks for a 0.5% monthly gain and a yearly core rate near 3.4%; after Bank of America's hawkish turn, a soft surprise would carry more weight than another firm number, which is broadly expected.

Notable Earnings This Session

Pre-Open

Carnival headlined the morning with a record quarter the market sold anyway (covered in Top Movers), the clearest sign that, after a long run, even strong results now have a high bar to clear.

Post-Close

FedEx was the after-the-bell event, its first report since the freight spinoff. KB Home (KBH) rose 2.2% to $52.73 ahead of its own evening report as easing Treasury yields lent the homebuilders a bid. The bigger test lands Wednesday after the close, when Micron reports into the teeth of the memory scare.

What Drove the Tape

Monday's selling changed targets. The rotation that punished the megacap platforms a day earlier flipped into a memory-chip rout that began in Seoul, where the KOSPI fell almost 10% and halted twice on circuit breakers after a report that SK Hynix might slow its AI-memory buildout. The fear crossed the Pacific into Micron, Marvell, Taiwan Semiconductor and the rest of the group, and Bank of America's call for three Fed rate hikes this year handed the sellers a macro reason to keep going; technology closed down more than 4% and the Nasdaq 100 lost 3.3%. Yet the broad market barely flinched: the Dow finished roughly where it began, money flowed into staples, health care and utilities, and Treasuries drew a haven bid that pushed yields lower even as the rate-hike drumbeat grew louder. The names that took Monday's beating, Microsoft and Amazon among them, actually firmed, a near-perfect mirror of the session before. Whether a one-day scare over memory pricing hardens into a real reassessment of the AI-hardware trade is the question now, and Micron's report on Wednesday will be the first hard read on it.
