Nasdaq Slips as Late Tech Slide Erases Chip Gains

Now I have enough data to write the article. Here it is:

The Nasdaq Composite fell 0.7% on July 2 as a late-session selloff in semiconductor stocks erased early gains, even as the Dow Jones Industrial Average touched a fresh all-time high ahead of the Independence Day holiday.

What Happened

The day's market highlights began with optimism. Chip and growth stocks climbed in early trading after a weaker-than-expected June jobs report — just 57,000 payrolls added versus consensus expectations, with the unemployment rate ticking down a notch to 4.2% from 4.3% — fueled bets that the Federal Reserve would hold rates steady for longer. But that initial momentum proved fragile.

By midday, the tech decline accelerated as the profit-taking that began last week in semiconductor names deepened. The Information Technology Select Sector SPDR Fund (XLK) shed 2.6% on the session, dragging the Nasdaq lower and offsetting broad gains elsewhere. Of the S&P 500's 500 components, roughly 354 — a 70% share — finished in positive territory, a clear signal that the weakness was concentrated rather than systemic.

Chip Sector Under Pressure

The chip sector bore the heaviest losses. Sandisk Corporation (SNDK) tumbled 10.6%, and Applied Materials (AMAT) plummeted 10%, continuing a slide that began in late June. Intel (INTC) and Marvell Technology (MRVL) each fell approximately 9%. Nvidia (NVDA) and Advanced Micro Devices (AMD) opened higher alongside Micron Technology (MU) before reversing sharply during the afternoon session, turning red after early gains faded.

The Philadelphia Semiconductor Index (SOX) fell roughly 6% across Tuesday and Wednesday combined, placing the two-session decline among the steepest since the early June rout. The VanEck Semiconductor ETF (SMH) dropped 4.5% on Tuesday alone, led by a 13.6% decline in Teradyne (TER) and an 11.5% slide in KLA Corporation (KLAC).

The late-session selling was amplified by cascading losses in Asian markets. South Korea's Kospi tumbled nearly 8%, paced by SK Hynix (HXSCL), which lost approximately 15%, and Samsung Electronics (SSNLF), which shed around 9%. In Hong Kong, Semiconductor Manufacturing International Corporation (SMIC) fell roughly 10%, while Hua Hong Semiconductor lost close to 13%, illustrating how the Nasdaq tech slip reverberated across global chip supply chains.

Diverging Fortunes

The session's starkest storyline was the divergence between semiconductors and the rest of the market. While the Nasdaq tech decline dominated the tape, the Dow's relative steadiness reflected an ongoing rotation into sectors less exposed to elevated AI valuations: healthcare, consumer staples, and utilities each advanced.

Strategic and AI Context

The chip sector has been the singular engine of U.S. equity outperformance in the first half of 2026. The Philadelphia Semiconductor Index nearly doubled during the second quarter alone, while names like Micron — still up roughly 262% year-to-date despite recent losses — and Sandisk — up more than 756% for the year — accumulated multiples that increasingly drew scrutiny on valuation grounds.

The catalyst for the two-session pullback reflects a confluence of factors. First, pure profit-taking after a historical run: the sector surged more than 80% in the first six months of the year, its strongest half-year performance in over a decade. Second, a genuine reassessment of how sustainably elevated AI infrastructure spending can continue to drive semiconductor earnings per share beyond already extraordinary levels. Third, notable short-side positioning: activist investor Michael Burry disclosed new bearish bets against Nvidia, Applied Materials, and the iShares Semiconductor ETF (SOXX), a move that received wide market attention.

What Comes Next

With U.S. markets closed Thursday for the Independence Day holiday, the next major catalyst arrives when trading resumes Monday, July 6. The question investors will be watching: whether the two-session semiconductor selloff constitutes a healthy consolidation within an ongoing structural cycle, or the opening chapter of a broader tech decline as AI monetization timelines get repriced.

Memory specialists including Micron and Sandisk remain well-supported by tight supply conditions and strong AI data center demand, which analysts expect to sustain DRAM and NAND pricing through the remainder of the year. Applied Materials and Lam Research face a similar test — whether recent guidance softness reflects a temporary digestion of capacity orders or a more durable deceleration in equipment spending.

Outlook

The July 2 session crystallized a tension that has been building across 2026's remarkable technology rally: exceptional year-to-date gains invite equally exceptional scrutiny. The Nasdaq tech slip did not break the market — 70% of S&P 500 stocks advanced — but it revealed how concentrated the index's upside has become in a handful of semiconductor and megacap names. How quickly that concentration reasserts itself, or how orderly it continues to unwind, will define the market's direction into earnings season.
