Key Highlights

  • Applied Materials shares slipped on October 6 with no company-specific news, part of a broader pullback in equipment stocks.
  • The company's machines handle thin-film deposition, etching, ion implantation and wafer inspection across chip production.
  • Weakness in memory and storage stocks, including Seagate, Western Digital and Micron, appeared to weigh on equipment-sector sentiment.
  • AMD's chief executive said the company would substantially increase Manufacturing capacity, a signal that did not lift equipment stocks on the day.

Applied Materials (NASDAQ:AMAT) slipped on Tuesday, moving lower with other semiconductor-equipment makers in the S&P 500 while chip designers led the technology rally. No company announcement explaining the move was found. KLA (NASDAQ:KLAC), Lam Research (NASDAQ:LRCX) and Teradyne (NASDAQ:TER) also lost ground.

On the other side of the chip trade, Marvell Technology (NASDAQ:MRVL) rallied after lifting its Revenue outlook to $20 billion for fiscal 2028 from $18 billion at its investor day. AMD (NASDAQ:AMD) climbed to a record, Broadcom (NASDAQ:AVGO) gained, and Nvidia (NASDAQ:NVDA) closed at an all-time high. The contrast showed investors leaning toward companies that sell AI chips directly, rather than the suppliers of the factories that make them.

A Leading Toolmaker

Applied Materials is one of the biggest semiconductor-equipment makers by revenue. Its machines handle many steps in chip production, including depositing thin films, etching, implanting ions, polishing wafers flat and inspecting them. It also supplies equipment used to make display panels. Its customers include contract manufacturers such as TSMC (NYSE:TSM), memory producers and companies that build their own chips.

Because it spans so many processes and customers, Applied Materials is often viewed as a broad proxy for chip-industry Capital spending. That makes its shares sensitive to shifts in sentiment about how much manufacturers will invest, as well as to trade policy, since a meaningful portion of its sales go to customers in Asia.

Signals Pulling Both Ways

Some of Tuesday's developments pointed to continued investment. AMD's chief executive said the company would substantially increase manufacturing capacity, adding that Demand for compute continues to outrun supply. Government data showed US imports of Capital Goods hit a record $146.4 billion in August, driven by semiconductors and AI equipment.

At the same time, memory and storage stocks were under pressure. Seagate (NASDAQ:STX) and Western Digital (NASDAQ:WDC) fell sharply after reports of a contest for TDK's hard-drive heads business, and Micron (NASDAQ:MU) slipped. Memory makers are significant buyers of equipment, so weakness in that corner can ripple into toolmakers. The overall picture was of a rotation within technology rather than a retreat from it.

Records for the Major Indexes

The S&P 500 rose 44.98 points to a record 7,818.93, and the Nasdaq Composite closed at a record just under 27,600. The Dow gained 253.38 points to 51,521.28, while the Russell 2000 slipped. Treasury yields eased, with the 10-year yield at about 5.275, and the VIX Volatility gauge fell to about 15.

Utilities led sectors after Constellation Energy's (NASDAQ:CEG) 20-year nuclear power deal with Google (NASDAQ:GOOGL), and health care was the only sector to decline.

Foundry Orders Will Settle the Question

Applied Materials and its peers will be watched closely during the third-quarter Earnings season for updates on orders from foundry, logic and memory customers and for any change in how customers describe their spending plans for next year.
