• NVDA -3.55%
• AMD -5.51%
• INTC -5.12%
• ARM -8.11%
• MSFT -0.71%

Quick Read

• AMD and Intel are down 8% and 6% in a pure rotation trade, not a fundamental break. Both still sit up over 100% year to date.
• NVIDIA holds flat while ARM trades at 289x trailing earnings, exposing the valuation gap driving today's hard sell-off in second-tier AI chip names.
• Microsoft and Meta Platforms report July 29, and hyperscaler capex commentary will either validate the AI infrastructure trade or accelerate the rotation already underway.
• Act now: the analyst who called NVIDIA in 2010 just named his top 10 AI stocks — and AMD didn't make the cut. Grab the names FREE today.

Advanced Micro Devices (NASDAQ:AMD) stock is down 9% in midday Tuesday trading to $453.37, while Marvell Technology (NASDAQ:MRVL) shares are off 7% to $175.52 and Intel (NASDAQ:INTC) stock is down 6% to $85.82. Meanwhile, Arm Holdings (NASDAQ:ARM) shares are also down 7% to $246.37.

NVIDIA (NASDAQ:NVDA) stock, by contrast, is up 0.5% to $197.58, and Broadcom (NASDAQ:AVGO) shares are down by only 0.5% to $381.30. The split is telling: the AI chip trade is narrowing to its clearest leaders while the higher-beta, richly priced second-tier names are getting trimmed hard.

Flight to the Leaders, Not a Fresh Catalyst

There's no company-specific news driving today's sell-off in AMD, Marvell, Intel, or Arm. Instead, investors appear to be consolidating exposure into the AI infrastructure leaders and cutting back on the crowded, higher-multiple satellites ahead of a heavy Big Tech earnings slate.

The context matters. AMD stock is still up 112% year to date, Marvell shares are up 106%, Intel stock is up 133%, and Arm shares are up 122%. Even after today's drop, these are enormous 2026 gains, and the reaction reads as profit-taking within a big run rather than a fundamental break.

NVIDIA stock, meanwhile, is up only 6% year to date, and Broadcom shares have gained 10%. The leaders haven't stretched as far, which is exactly why capital is rotating toward them today.

Valuation Jitters Are Doing the Work

The dispersion in trailing multiples helps explain the price action. NVIDIA trades at a trailing P/E ratio of 30.28x, and Broadcom sits at 63.14x. Marvell is at 60.27x, AMD carries a 150.54x multiple, and Arm stock trades at a striking 289.41x. Intel isn't profitable on a trailing 12-month basis, so there's no meaningful TTM P/E ratio to anchor its valuation.

The pattern lines up neatly with today's action. The names holding up carry more moderate multiples, and the hardest-hit names are either the most richly valued (Arm, AMD) or unprofitable (Intel). That's the definition of a valuation reset inside a crowded theme.

Intel's move is the most striking part. Intel just reported Q2 2026 revenue of $16.1 billion, up 25.4% year over year, with Data Center and AI revenue up 59%. CEO Lip-Bu Tan stated, "AI is driving unprecedented demand for compute." Intel stock is still selling off today, which underscores that this is a rotation story, not an earnings-driven one.

Sector ETF Cushioned by Leader Weightings

The iShares Semiconductor ETF (NASDAQ:SOXX) holds every name discussed here, and its heavy NVIDIA and Broadcom weightings cushion the fund from the broader sell-off in second-tier names.
