AMD shares plunge amid sector sell‑off after Nvidia CEO resignation

Advanced Micro Devices fell sharply on November 13, 2026, as investors unwound a rally that had lifted the stock nearly 50% in the prior week. The drop followed Nvidia’s chief executive stepping down, which sparked broader concerns about regulatory scrutiny of AI‑chip exporters. The sell‑off was compounded by profit‑taking after a multi‑day rally in the semiconductor sector.

The sharp decline reduces AMD’s market value and may trigger stop‑loss orders for traders exposed to AI‑chip stocks. The sector‑wide risk perception could also dampen demand for AMD’s data‑center products, affecting revenue expectations, according to the company’s filing.
