AMD shares climbed 40% from their November 5 low as Nvidia shares fell after Jensen Huang resigned following 33 years as CEO. AMD traded around $562, about 15% below its all-time high, with $600 the next key test, according to BeInCrypto. Nvidia’s board opened a probe on November 8 into Huang’s relationship with an alleged Chinese operative, and a second affair report followed three days later. CFO Colette Kress became interim CEO as the board began searching for a permanent replacement. Nvidia shares fell from $196.25 to about $160 on Thursday, an 18% drop, while AMD gained as investors shifted toward the chipmaker seen as Nvidia’s closest GPU alternative. AMD has reclaimed the 0.618 Fibonacci level at $545; the next resistance is $592, near the $600 mark and Oppenheimer’s price target. A break above could put the October record of $658 in play, while a close below $514 would invalidate the bullish setup. The article also cites a potential weakening of Nvidia’s CUDA advantage: Anthropic took about three days to bring up prompt processing for one model on AMD MI355X GPUs, compared with six to 12 months using traditional engineering. The result covered one workload, not a full migration. Risks include Nvidia earnings on November 17, its permanent CEO choice, AMD’s valuation and a drop below $514.
