AXT Inc (NASDAQ:AXTI) fell about 10.4% by late morning on Friday. No company-specific news was identified for the day. The decline lines up with a sweeping sell-off in semiconductors, chip materials and optical hardware set off by Intel (NASDAQ:INTC)'s disappointing fourth-quarter outlook and amplified by renewed anxiety about artificial intelligence spending.

A Narrative Tied to AI

AXT makes compound semiconductor substrates, the specialized wafers on which certain chips and optical devices are built. Its indium phosphide substrates are used in components for optical communications, which has tied the company to the AI Data Center build-out, where high-speed optical links are in heavy demand. Headlines around its second-quarter results pointed to record Demand for indium phosphide linked to AI, and the stock tends to move with the optical and AI hardware complex when sentiment turns.

A Sharp Sentiment Turn

Intel guided fourth-quarter Revenue to $15.0 billion to $16.0 billion against expectations of roughly $17.1 billion. Optical and networking stocks including Lumentum (NASDAQ:LITE), Coherent (NYSE:COHR) and Applied Optoelectronics (NASDAQ:AAOI) were among the hardest hit, and chip materials and equipment suppliers were dragged lower alongside them. The S&P 500 fell 140.32 points, or 1.8%, to 7,580.07 and the Nasdaq Composite dropped 747.73 points, or 2.9%, to 25,437.00, as Intel's weak outlook triggered a chip rout and Amazon (NASDAQ:AMZN)'s results revived worries about AI spending. A market strategist summed up the mood by saying strong AI demand is no longer enough on its own.

Why Small Names Feel It More

Smaller, higher-volatility names such as AXT can feel these swings more acutely than large-cap peers. When investors reduce exposure to a theme they often sell the more speculative, momentum-driven holdings first. Federal Reserve officials said rates may need to go higher, and futures priced a strong chance of a December hike, while US midterm elections on November 3 add another source of uncertainty.

What Investors Will Watch

Investors will focus on AXT's upcoming third-quarter report and any commentary on indium phosphide demand, customer orders, capacity and pricing, along with results from other optical and AI hardware suppliers due in the coming days.
