Dell and chip stocks plunge on AI infrastructure spending concerns

Global technology and semiconductor stocks are tumbling as the Philadelphia Semiconductor Index tracks to erase over $1 trillion in market value. Dell shares plunged 11% following a Barclays downgrade, leading a data center sell-off driven by doubts over enterprise AI adoption timing and high capital costs. Rising interest rates, an IMF warning on AI returns, and a chip architecture breakthrough by China's CXMT are accelerating losses across major memory makers like Samsung, SK Hynix, and Micron.
