Tech sells off; broad market treads water on holiday week — July 5, 2026

S&P 500 +0.00% · Nasdaq -0.80% · Dow +1.14% · VIX 15.8 — July 5, 2026

The Nasdaq fell 0.80% on what amounts to a half-speed trading day after the July 4th holiday, while the Dow managed a 1.14% gain and the S&P 500 flatlined. Breadth was negative (55 down, 43 up in the top 100), signaling no real conviction either way. This is thin-volume chop masquerading as direction.

The damage clustered in semiconductors and infrastructure plays. KLA, KLAC, and Marvell all cratered between 9-11% on no major news—just repositioning and the ambient tech anxiety that's plagued 2026. Navitas, a chip designer, dropped 12.5% in a head-to-head comparison piece with Broadcom. Meanwhile, Corning fell 10.8% hard enough that Jim Cramer said the drop "seems extreme," which tells you the move was mechanical, not fundamental. Crypto miners got hammered too: Bitcoin miner IREN tanked 10.4% after a $700 million CEO stock award announcement spooked the market. Tesla (WULF) and BlackBerry (BB) also took double-digit hits in weak volume.

Notably absent today: any insider cluster buys among the big fallers. That's the real message. Nobody running these companies is pulling the trigger to buy their own stock at these levels. When insiders stay on the sidelines during a selloff, it usually means they're waiting for more blood. The market's patience is being tested on a lazy Friday afternoon, and it's not winning that bet.
