Dell Technologies NYSE:DELL shares fell sharply on Tuesday as investors sold AI hardware stocks amid concerns about customer concentration and pressure on server margins, according to a Tuesday market report.

Dell shares dropped more than 11% during trading after an analyst note highlighted risks tied to the company's AI server business. The report maintained a positive view on Dell but pointed to dependence on a small group of major customers as a potential challenge.

Dell has also faced questions about profitability as demand for AI infrastructure grows. Investors have been watching whether higher AI server sales can translate into stronger margins while the company expands its data center offerings.

The broader technology sector also faced pressure as investors reassessed valuations across AI-related companies. Dell's stock decline came as several semiconductor and infrastructure names moved lower during the session.

Despite the recent pullback, Dell has continued to benefit from rising demand for AI servers. However, investors appear focused on whether growth in the AI infrastructure market can offset concerns around margins and customer concentration.
