Western Digital and Seagate Lead Friday's Tech Selloff With Near-10% Drops

Storage names are taking the brunt of the open, with Seagate down 14.8%. On the other side, ON Semiconductor leads the gainers, leaving the spread across this stock universe at roughly 21 points in a single session.

Three names in our 383-stock board closed with double-digit gains, led by Accenture's 15.6% jump to $211.97, a move that size is rare for a mega-cap consultant. The downside was far tamer, with AMC's 8.2% slide the worst of it.

Accenture opened 22% higher, a move you almost never see from a mega-cap IT services name, while Corteva dropped 82% to $13.96 at the other end of the board. Synopsys, McKesson and IBM round out a gainers list that is all up at least 5.9%.

The tape spread nearly 12 points wide at the close: C3.ai finished up 6.43% at $11.01 while Moderna gave back 5.52%. Enterprise tech names took the top four gainer slots, and the losers skew toward high-beta momentum.

Moderna is the session's widest move at the open, off 7.34% to $188.54, while Hewlett Packard Enterprise leads the upside at +6.27%. The gainer list skews toward AI infrastructure names; the losers span biotech, power and defense.

Chips and hardware took the top five slots at Thursday's close, led by ON Semiconductor's 5.52% gain, while every big decliner but one was a cybersecurity name. Zscaler's 9.88% drop to $193.43 was the worst in the group.
