AMD Upgraded by William Blair as Nvidia Loses CEO

Advanced Micro Devices (NASDAQ: AMD) shares advanced 6% on Wednesday, November 12, 2026, after William Blair upgraded the stock to Outperform from Market Perform. The move coincided with leadership changes at rival artificial intelligence chipmaker Nvidia Corporation (NASDAQ: NVDA), which saw its CEO resign alongside several firm downgrades.

### Money Play If William Blair's upward revision and expanding Data Center metrics hold, watch $NVDA+WL because sentiment contagion across chip peers can trigger sharp valuation shifts and momentum rotations.

## Catalyst Analysis: William Blair Upgrade and 2027 Estimates William Blair’s bullish stance is underpinned by rising consensus projections for 2027 earnings, which have been revised to $17.69 per share from $15.33 over a three-month span. Consensus price targets have climbed significantly to $659, sitting 12% above current trading levels.

Third-quarter revenue expanded 45% to $13.4 billion, with Data Center revenue nearly doubling to $8.5 billion. CEO Lisa Su noted that demand outpaces supply and guided for revenue growth exceeding 80% in 2027, driven by Instinct GPU market share gains and EPYC host CPU selections in custom platforms such as OpenAI's infrastructure.

Valuation remains near historical averages, with the stock trading at 37x forward earnings compared to a five-year average of 35x and prior peaks near 67x in June. Free cash flow totaled $554 million in the third quarter amid inventory expansion to $11.5 billion, underscoring ongoing capital intensity among major AI clients.
