Nasdaq 100 Enters Correction, SanDisk Sinks Over 50% From Peak: Stock Market Today

The Nasdaq 100 officially slipped into correction territory on Tuesday, falling more than 10% from its early June record high as the AI-driven sell-off deepened on mounting concerns over rising competition from China.

The memory sector has been at the heart of July’s rout.

SanDisk Corp. (NASDAQ:SNDK) — the S&P 500’s top performer of 2026 before the downturn — has plunged more than 50% from its peak, while Micron Technology Inc. (NASDAQ:MU) has lost roughly one-third of its market value.

• Sherwin-Williams stock is charging ahead with explosive momentum. What’s driving SHW stock higher?

Peers SK Hynix Inc. (NASDAQ:SKHY), Seagate Technology Holdings plc (NASDAQ:STX) and Samsung Electronics Co. Ltd. (OTC:SSNLF) also sold off sharply Tuesday as investors reassessed the memory sector after China’s memory champion, ChangXin Memory Technologies (CXMT), surged 466% in its Shanghai trading debut.

Across U.S. equity markets by midday Tuesday, the tape was sharply bifurcated, with earnings winners and rate-sensitive corners rallying against a bleeding AI-hardware complex.

The S&P 500 added 0.4% to 7,440, while a blitz of blue-chip earnings beats powered the Dow Jones more than 650 points higher, or 1.3%, to 52,865 points.

Sherwin-Williams Co. (NYSE:SHW) led the Dow index, surging 8.3% after beating on earnings per share of $3.70 versus the $3.52 consensus and raising full-year adjusted EPS guidance to $11.80-$12.20. 

Coca-Cola Co. (NYSE:KO) gained 5.3%, reaching fresh record highs, after topping estimates at 97 cents per share and boosting its outlook on World Cup-fueled demand.

The Nasdaq 100 fell 0.6% to 27,882. Within Magnificent Seven stocks, Microsoft Corp. (NASDAQ:MSFT) rose 2.2%, Meta Platforms Inc. (NASDAQ:META) share price was volatile ahead of Wednesday’s earnings, Alphabet Inc. (NASDAQ:GOOGL) climbed 1.9%, and Apple Inc. (NASDAQ:AAPL) was up 0.9% before Thursday’s report. 

West Texas Intermediate crude sank 5% to $78.50 a barrel and Brent slid 5.2% to $83.81, amid rising hopes for a ceasefire. The 10-year Treasury yield fell for a third straight session, down six basis points to 4.60%.

The Federal Reserve’s two-day meeting kicked off Tuesday, with rate futures assigning roughly a 35% probability to a hike at Wednesday’s decision under Chair Kevin Warsh and about 80% odds to a September move, after June inflation cooled to 3.5% from 4.2%.

On the losing side, the Invesco WilderHill Clean Energy ETF (NYSE:PBW) dropped 3.6% – hit by a 12.5% slide in Bloom Energy Corp. (NYSE:BE) ahead of its report tonight.

The AI hardware complex was the session’s bleeding edge.

Aside Micron’s 8.9% drop, Advanced Micro Devices Inc. (NASDAQ:AMD) lost 6.7%, Intel Corp. (NASDAQ:INTC) fell 5.4%, and equipment makers Applied Materials Inc. (NASDAQ:AMAT) and Lam Research Corp. (NASDAQ:LRCX) shed 7.9% and 8.2% ahead of Lam’s Wednesday report.

Tuesday’s Earnings Winners and Losers

Among earnings movers, Repligen Corp. (NASDAQ:RGEN) topped the Russell 1000, soaring 15.6% after beating with adjusted EPS of 54 cents versus 45 cents expected on revenue up 12% to $204 million, raising full-year guidance and unveiling a roughly $1.5 billion cash-and-stock deal for BioLife. 

IQVIA Holdings Inc. (NYSE:IQV) jumped 12.7% on a revenue beat of $4.37 billion, adjusted EPS of $3.15 and a full-year guidance hike backed by record clinical bookings. 

TransUnion (NYSE:TRU) rallied 10.9% after adjusted EPS of $1.23 beat the $1.15 consensus on 15% revenue growth, with full-year guidance raised to $5.13 billion-$5.16 billion. 

Armstrong World Industries Inc. (NYSE:AWI) added 10.8% after beating on EPS ($2.36 versus $2.25) and revenue while lifting its full-year sales outlook.

Boeing Co. (NYSE:BA) gained 4.9% following its quarterly report, with deliveries up 14% year over year, a $695 billion backlog and the FAA’s July 23 restoration of its certification authority still fresh.

On the downside, Amkor Technology Inc. (NASDAQ:AMKR) collapsed 24.5% — the Russell 1000’s worst — as a soft third-quarter revenue outlook of $2 billion-$2.1 billion overshadowed a record quarter in which EPS of 70 cents crushed the 47-cent consensus. 

Sanmina Corp. (NASDAQ:SANM) plunged 18.9% despite beating fiscal third-quarter estimates with adjusted EPS of $3.31 versus $2.77, as the midpoint of its $3.3 billion-$3.6 billion revenue guide sat below the $3.5 billion consensus and the AI-hardware unwind amplified the damage. 

Corning Inc. (NYSE:GLW) sank 15.7% even after core EPS of 78 cents beat by two cents on sales up 17% to $4.74 billion; a merely in-line third-quarter outlook triggered profit-taking in one of the year’s hottest AI-optics names, despite CEO Wendell Weeks pointing to a coming phase of accelerating growth.

United Parcel Service Inc. (NYSE:UPS), meanwhile, slid 5.6% after its morning report failed to impress.

After the close, attention turns to Visa Inc. (NYSE:V), along with Ford Motor Co. (NYSE:F)Seagate Technology Holdings plc,  KLA Corp. (NASDAQ:KLAC) and Teradyne Inc. (NASDAQ:TER).
