Advanced Micro Devices closed up 5.86% at roughly 585 on Thursday, the day Nvidia announced Jensen Huang had resigned as CEO, president and director, effective immediately. The resignation followed reports about his personal conduct and a suspected Chinese intelligence link, according to a Nov. 13 technical analysis. CFO Colette Kress, who has held the finance post since 2013, becomes interim CEO.

Nvidia fell as much as 14% intraday before closing down 4.34%. AMD and Broadcom led the S&P 500, with Broadcom up 5.54%; the Nasdaq closed about 0.4% lower. The divergence marks a sharp repricing of relative positioning across the AI semiconductor trade in a single session.

Why is AMD the direct beneficiary?

The analysis frames the move as supplier diversification, not an AMD earnings story. A CEO search launched days before Nvidia's Nov. 17 earnings report gives large buyers a reason to hedge their chip supply. AMD is the most direct alternative, and the company says demand is already above supply.

Broadcom strengthens the diversification case. Its AI semiconductor revenue rose 221% to $16.7 billion in its latest fiscal quarter — a tripling in one year that signals buyers are already spreading orders across suppliers.

The read from the analysis is blunt: the market is hedging Nvidia exposure, and a steady handover could return some of AMD's gains. Kress has been CFO since 2013, and Nvidia's chip roadmap is already public, so the disruption may prove limited. AMD has also moved a lot in about a week.

What does the technical picture show?

AMD peaked near 660 in early October, then fell inside a descending channel to about 403 in early November — a drop of roughly 39%, or nearly two-fifths of its market value in a month. The rebound broke above the channel's upper line near 522 and has now reached 585, putting the stock about 45% above the early November low.

Momentum indicators are constructive but not fully aligned:

• The 21 EMA at 520.43 remains below the 78 EMA at 534.72, so the bearish crossover has not yet reversed.
• Price trades above both moving averages.
• RSI at 63.51 is bullish and still below overbought territory.

What are the scenarios and key levels?

The analysis sets out three conditions, not recommendations, with a one-to-two-week horizon anchored to Nvidia's Nov. 17 earnings as the key event:

• Base case: a four-hour close above 585 targets 640, then the all-time high zone near 660.
• Pullback case: a retest of 530 that holds — supported by the slow EMA, the 525.50 level and the broken channel line — keeps the breakout valid.
• Invalidation: a four-hour close below 530 kills the bullish view outright.

Resistance sits at 585, 640 and 660 (the all-time high zone). Support stands at 530, 520 — the fast EMA and the channel line — and 425.

The setup is clear: AMD has reclaimed a third of its October drawdown in two weeks on a competitor's governance shock, and 585 is the level that decides whether 640 comes next.
