Dell (DELL) selloff deepens second day, falls 8%+ Thursday, worst S&P 500 performer (Oct 15)
What happened
Dell shares fell 8.4% to $465.14 on Thursday, the worst performance in the S&P 500 for the session, extending Wednesday's roughly 11% plunge for a two-day decline of about 19%. Dell tumbled more than 8% in afternoon trading, falling below its 50-day moving average in heavy volume and triggering a sell signal; shares had reached a profit zone from a 469.47 buy point but round-tripped that gain. Even after the two-day selloff, Dell remained up about 270% in 2026, down from a roughly 355% gain through Tuesday's close, and still on pace for its best year on record.

- Dell (DELL): direct — fell 8.4% to $465.14 on Thursday, worst-performing S&P 500 component that session, after an ~11% drop Wednesday; fell below its 50-day moving average in heavy volume, triggering a sell signal, and round-tripped the gain from a 469.47 buy point.
- Hewlett Packard Enterprise (HPE): fell 6.5% to $58.99 Thursday, down more than 14% since Tuesday's close — its worst two-day performance since April 2025 — on the same Barclays downgrade.
- NetApp (NTAP): same Barclays downgrade group; under pressure alongside Dell and HPE as the hardware-valuation thesis is questioned.
