AMD sank 8.8% Friday, Nov. 13, as Broadcom and Marvell also fell, giving back part of the gains that had set them apart from Nvidia during its leadership upheaval.

Broadcom lost 4.8% and Marvell dropped 4.7%. All three declined more than both Nvidia, down 2.0%, and the iShares Semiconductor ETF, or SOXX, which fell 3.7%.

The comparisons use Yahoo Finance's split-adjusted closing prices through the 4 p.m. ET regular-session close on Nov. 13, excluding after-hours trading. Friday's changes are measured against Nov. 12; weekly changes are against Nov. 6.

Nvidia announced Thursday that Jensen Huang had resigned as president, chief executive and a director, effective immediately. Chief Financial Officer Colette Kress became interim CEO while retaining her finance role, and the board began a search for a permanent successor.

The selloff narrowed—but did not erase—the week's divergence. Through Thursday, AMD had gained 30.3% from the previous Friday's close while Nvidia had lost 11.0%. AMD, Broadcom and Marvell all finished the week with double-digit gains despite Friday's retreat.

The declines also exceeded the broader market's: the S&P 500 fell 0.4% Friday. SOXX provides a sector comparison: its stated objective is to track a U.S. semiconductor-stock index. The price comparisons establish relative performance, not the cause of the selling.
