Dell Technologies shares experienced an 11.6% decline following a downgrade from Barclays, which moved the company from ‘Overweight’ to ‘Equal Weight’. The downgrade cited concerns regarding stretched valuations after a 300% gain in 2026 and potential slowing growth as memory chip prices normalize.

This decline contributed to a broader sell-off in the AI physical infrastructure sector, affecting companies such as CoreWeave, Nebius, and Oracle. Combined with a hot Consumer Price Index report, this movement resulted in an estimated $80 billion loss in market value across these related firms. Despite the volatility, Dell reported a record $95 billion AI server backlog, with CEO Michael Dell projecting AI server revenue to reach $75 billion for the current fiscal year.
