  • The stock traded in a day range of $467.22 to $495.00 on volume of 9.51 million shares.
  • The decline deepens a multi-week semiconductor selloff as investors reassess AI infrastructure spending sustainability and circular-financing concerns tied to Nvidia and OpenAI.
  • Reports indicate a Chinese state-backed firm has begun mass-producing deep ultraviolet lithography equipment, threatening Western equipment makers' technology edge.
  • The decline mirrors steep losses among chip peers AMD, ASML, SK Hynix and Samsung, even after Applied Materials raised its 2026 equipment revenue growth guidance to over 30% in May.

China Lithography Progress Deepens Sector-Wide Selloff

Applied Materials (NASDAQ:AMAT) shares slid sharply in Tuesday trading, deepening a multi-week semiconductor selloff as investors reassess AI infrastructure spending sustainability and circular-financing concerns tied to Nvidia (NASDAQ:NVDA) and OpenAI. The decline was compounded by reports that a Chinese state-backed firm has begun mass-producing deep ultraviolet lithography equipment, threatening Western equipment makers' technology edge.

Applied Materials is the world's largest supplier of semiconductor wafer fabrication equipment, providing materials engineering solutions, equipment, services and software used to manufacture virtually every advanced semiconductor chip and display in the world. The company operates through two primary segments, Semiconductor Systems and Applied Global Services, positioning it at the heart of the semiconductor and advanced display supply chain for chipmakers such as TSMC (NYSE:TSM), Intel (NASDAQ:INTC) and Samsung.

The decline mirrors steep losses among chip peers including AMD (NASDAQ:AMD), ASML (NASDAQ:ASML), SK Hynix (NASDAQ:SKHY) and Samsung, even after Applied Materials raised its fiscal 2026 equipment revenue growth guidance to over 30 percent from 20 percent in May, citing record DRAM and advanced packaging demand, a data point that highlights a growing disconnect between fundamentals and sentiment-driven valuation resets ahead of key hyperscaler earnings this week.

Valuation Reset Contrasts With Raised Fundamentals

Applied Materials carries a market capitalization of approximately $378.29 billion and trades at a forward price-to-earnings ratio of 29.18 and a trailing P/E of 48.18, with reported earnings per share of $9.89. Shares have traded in a 52-week range of $154.47 to $739.67, and the stock offers a dividend yield of 0.40 percent.

Founded in 1967 and headquartered in Santa Clara, California, Applied Materials employs approximately 36,500 people worldwide and invests heavily in research and development to maintain its technology leadership across the wafer fabrication equipment industry, even as near-term sentiment remains dominated by concerns over Chinese competition and AI capital expenditure sustainability.

Conclusion

Applied Materials' steep decline reflects a broad reassessment of semiconductor equipment valuations amid intensifying competitive pressure from China and continued scrutiny of AI infrastructure financing, even as the company's own raised fiscal 2026 guidance points to robust underlying demand. This week's hyperscaler earnings reports will likely determine whether the current valuation reset stabilizes or extends further.
