Key Highlights

  • Arm Holdings ranked second among Nasdaq-100 gainers on Friday, behind only Rocket Lab, trading at $313.52 at one point during the session with no company-specific news found.
  • Arm licenses its chip instruction-set architecture to companies including Apple, Qualcomm and Nvidia, making it a broad play on Demand across the chip industry from phones to AI servers.
  • The semiconductor sector surged broadly: Teradyne, Monolithic Power, Microchip, Texas Instruments, KLA, Intel and Analog Devices were all among the Nasdaq-100's top gainers, and Nvidia hit a record high topping a $5.7 trillion Market Value intraday.
  • Treasury yields reversed higher by the close after an early drop, leaving the 10-year near its highest level since 2002, while Arm's next Earnings report is expected November 4.

Arm Holdings (NASDAQ:ARM) shares soared on Friday, October 2, ranking second among Nasdaq-100 gainers, behind only Rocket Lab, as chip stocks led a broad rally in technology. Arm, the UK-based company whose chip designs power most of the world's smartphones and increasingly data-centre processors, did not announce any major news of its own. The move was attributed to a broad tech and semiconductor risk-on rally, with the stock trading at $313.52 at one point during the session.

No Single Trigger, Just Momentum

Arm does not manufacture chips itself. Instead, it licenses its instruction-set architecture and processor designs to companies such as Apple, Qualcomm and Nvidia, collecting licence fees and royalties on chips built with its technology. That makes it a play on demand across the whole chip industry, from phones to AI servers.

On Friday, that broad exposure paid off. The semiconductor sector surged across the board. Teradyne, Monolithic Power, Microchip Technology, Texas Instruments, KLA, Intel and Analog Devices were all among the Nasdaq-100's top gainers.

Nvidia Set the Tone

Nvidia, the leading AI chipmaker and a major Arm customer, hit a record high during the session, with its market value topping about $5.7 trillion intraday. Morgan Stanley named Nvidia its top semiconductor pick, describing the bank as seeing a new product cycle with a focus on CPUs alongside Nvidia's graphics-chip dominance.

That CPU angle matters for Arm, whose designs underpin many data-centre processors, including some of Nvidia's own.

Broadcom also climbed after a report said a financing syndicate is amassing about $60 billion to fund chips for Anthropic and other AI companies.

Why Rates Moved Chip Stocks

The macro trigger was the September jobs report. The economy added only 29,000 jobs, well below the roughly 84,000 expected, and revisions removed 60,000 jobs from July and August.

The soft data reduced expectations that the Federal Reserve will follow its September 16 hike, its first since 2023, with another at the October 27-28 meeting. Softer hiring eases interest-rate pressure on high-multiple growth equities by pulling borrowing costs lower, as one market explanation put it.

Companies valued on the promise of years of future growth, as many chip designers are, tend to benefit most when rate fears fade, because lower borrowing costs make those distant profits look more valuable today. That logic was on full display across the semiconductor group on Friday.

Yet bond yields told a more complicated story by the close. Treasury yields reversed higher after an early drop, leaving the 10-year near its highest level since 2002.

Records on the Board

The Nasdaq-100 set a record close at 30,807.93, up 306.37 points, while the Nasdaq Composite hit an intraday all-time high but closed short of a record. Information technology was the second-best S&P 500 sector, behind consumer discretionary.

Breadth remained narrow, with only a small minority of S&P 500 stocks trading above their 50-day moving averages.

Arm's November Earnings Will Test Royalty Growth

Arm's next earnings report is expected on November 4, and will be the key test of whether its royalty growth is keeping pace with AI enthusiasm. Before then, the Federal Reserve's October 27-28 meeting could swing sentiment toward high-valuation chip stocks. ASML's third-quarter results in mid-October will offer an early read on chip-industry demand, and the broader earnings season begins with PepsiCo on October 8.
