Investing.com — The tape suggests investors are already treating Advanced Micro Devices (AMD) as a relative winner. It trades at $513.73 (+14.41%) as of Nov 9, 3:38 PM EST. NVIDIA (NVDA) is at $177.20 (-5.06%) at the same time. That’s a roughly 19-point gap in one session. AMD is also up about 134% YTD but down 15.6% over the past month, so it isn’t a clean one-way run.
What’s hanging over Nvidia
-
Board probe: Nvidia’s board opened an independent investigation into CEO Jensen Huang over his relationship with a woman U.S. officials believe was a Chinese intelligence asset. Huang admitted an affair Read more (Nov 9, 2026).
-
Key-person risk: Bernstein notes Huang has about 60 direct reports and that it’s unclear who would step in. It expects the overhang to last a while, but kept its Outperform rating and $400 target Read more (Nov 9, 2026).

Regulatory angle: Citi flags governance, export-control compliance on H200 chips going to China (Read more (Nov 9, 2026).

The AMD bull case
An NH Investment & Securities analyst said rivals including AMD could draw more attention in the short term. Samsung, which has close ties to AMD, could also benefit Read more (Nov 9, 2026). If probe delays or product-launch slippage materialize at Nvidia, AMD is the obvious alternative for customers building AI capacity. Money rotating out of Nvidia may also be flowing into AMD.
The bear case
-
Sentiment, not fundamentals: No coverage found says Nvidia has lost customers or orders. Nvidia says it will continue “without interruption.”
-
Shared risk: The AI-spending worries behind Nvidia’s weakness, such as hyperscaler capex sustainability and valuation, also apply to AMD. Tighter export rules or antitrust rules for AI data centers would hit both.
-
Crowded move: A 14% one-day gain after a fall of about 15.6% in a month can reverse quickly if the probe turns out to be benign.
-
Bernstein’s warning: It said the main beneficiary of Huang’s removal “would clearly be China.” That points to sector-wide disruption more than a clean handoff to AMD.
Bottom line
AMD is a near-term sentiment beneficiary, and the price action shows it. A lasting share gain would need real evidence, such as Nvidia product delays, customer diversification or leadership changes. Nvidia’s Nov 17 earnings and the board probe’s findings are the next tests.
