AMD fell 8.8% on Friday, Nov. 13, while Broadcom and Marvell also declined, giving back some of the gains that had set them apart from Nvidia during its leadership upheaval.
Broadcom dropped 4.8% and Marvell fell 4.7%. All three stocks declined more than Nvidia, which lost 2.0%, and the iShares Semiconductor ETF, or SOXX, which fell 3.7%.
Comparisons are based on Yahoo Finance split-adjusted closing prices through the 4 p.m. ET regular-session close on Nov. 13, and exclude after-hours trading. Friday's changes are measured against Nov. 12, while weekly changes are measured 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 took over as interim CEO while keeping her finance role, and the board began searching 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 ended the week with double-digit gains despite Friday's declines.
