Key Highlights

● It was among the leading chip gainers alongside AMD and Teradyne.

● No company-specific news explained the move.

● Equipment stocks also got a talking point from Elon Musk's Terafab plans.

A big run into earnings

Applied Materials (NASDAQ:AMAT) gave investors plenty to think about heading into its results. On Monday, November 9, 2026, the chipmaking-equipment supplier soared, with one reading recording a strong close and others showing similar gains. Applied Materials was among the leading chip gainers of the day, alongside Advanced Micro Devices (NASDAQ:AMD) and test-equipment maker Teradyne (NASDAQ:TER).

No company-specific news was found to explain the move. The stock rallied with the semiconductor-equipment group, which posted some of the session's sharpest advances.

Why Thursday matters

Applied Materials reports quarterly results on Thursday, November 12. Because the company sells machines that deposit, etch and inspect the layers on silicon wafers, its outlook offers a window into how much chipmakers plan to spend on new capacity.

That makes the report a bellwether. Investors will listen for comments on Demand tied to artificial-intelligence chips, memory, and advanced logic. Any signal on whether customers are accelerating or slowing orders could ripple across peers such as Lam Research (NASDAQ:LRCX), KLA (NASDAQ:KLAC), ASML Holding (NASDAQ:ASML) and Entegris (NASDAQ:ENTG), all of which rallied on Monday.

Cisco Systems (NASDAQ:CSCO) also reports Thursday, adding a networking read on AI infrastructure.

What sparked the chip rebound

The surge was a sharp Reversal of last week's selloff. After the November 3 midterm elections, investors worried that Democratic victories could restrict US data-center construction, and semiconductor stocks were hit hard. On Thursday, November 5, the PHLX Semiconductor index suffered a deep one-day drop.

On Monday, the SOX rocketed to 10,033.93, its best day since July 30, according to news reports. Market data pointed to a Truth Social post by President Trump, in which he described data centers as "GOLD." A weekend report that Elon Musk's Terafab project is targeting about 1 million wafers a month by 2032 also gave equipment stocks a talking point.

Strategists credited cleaned-out positioning and forced dealer hedging for the speed of the rebound. Nvidia (NASDAQ:NVDA) was the only SOX decliner, according to market coverage, as its board pursued an independent review involving CEO Jensen Huang.

A market in relief mode

The broader market added fuel. The S&P 500 jumped 173.08 points to 7,549.94, its best day since April 8, and the Nasdaq-100 rallied to 27,907.62. Oil fell on hopes for a US-Iran peace deal, with Brent settling at $92.57 a barrel, easing Inflation worries. Breadth was strong: advancing issues on the NYSE outnumbered decliners by about four to one, according to market reports, and Volume on US exchanges reached 18.98 billion shares, slightly above the recent average.

Not every strategist was convinced. A strategist said, according to market data: "We believe markets are likely to remain very news flow driven and need to hold critical technical support levels."

Thursday's Print as the Test

The main event is Thursday's report. Investors will focus on Applied Materials' guidance for the coming quarter, its commentary on AI-related demand, and any discussion of export restrictions and China, an important market for chip-equipment makers.

Before that, Tuesday's October Consumer Price Index will be the last inflation report before the Federal Reserve's December 8-9 meeting, where traders see a strong chance of a rate hike. Further out, Nvidia's results on November 17 will provide another major test for the AI-chip Supply chain that Applied Materials helps equip.
