Dell Technologies Inc. (DELL) shares are facing a significant setback in pre-market trading on Monday, plunging 5.02% following a downgrade from Morgan Stanley. The move reflects growing concerns about the PC market and Dell's positioning within it.

The downgrade from Morgan Stanley has sparked a sell-off in Dell's stock, with investors reassessing their outlook on the company. It's worth noting that the initial report indicated a 2.9% drop, but the actual decline has been more severe, suggesting that market sentiment may have deteriorated further as more traders reacted to the news.

This downgrade doesn't only affect Dell; competitor HP Inc. is also feeling the impact, with its shares down 2.4% in pre-market trading. The simultaneous downgrades of both major PC manufacturers point to broader concerns about the industry's prospects, potentially signaling challenges ahead for the personal computer market.
