AMD stock dropped 8.75% on November 13, 2026, reversing early AI-driven gains as profit-taking swept through the semiconductor sector.

AMD's AI-fueled rally lifted leveraged ETFs AMDL, AMDG, AMUU and AMDC over 50% in five days. Friday's sharp reversal put those gains to the test.
AMD emerges as the superior investment choice compared to Intel, demonstrating stronger financial results with 45% revenue growth versus Intel's 21%, higher gross margins (54% vs 40%), and faster data center segment growth (97% vs 78%).
