Broadcom shares climbed 18% this week to about $346.60, while Nvidia fell 12.9% to roughly $162.60 as of Friday afternoon, November 13, 2026. The ratio of the two share prices rose 35.4%, its largest weekly increase since Broadcom went public in 2009. News that Nvidia CEO Jensen Huang had stepped down was among the developments in focus as the two semiconductor stocks moved sharply in opposite directions.
Broadcom-Nvidia share-price ratio sets a new weekly record
Broadcom's share price gained 35.4% relative to Nvidia's this week. The previous weekly high was close to 33%, set in the week ending December 13, 2024, when Broadcom reported earnings. The ratio reflects the stocks' sharply different weekly moves; it does not represent a comparable change in the companies' market values or fundamentals.
Broadcom posted a double-digit gain, while Nvidia lost nearly 13%. With both stocks in the semiconductor sector but moving in opposite directions, the gap between their share prices widened quickly over the week.
Huang's departure puts Nvidia leadership in focus
Nvidia said on Thursday that Jensen Huang had resigned as chief executive. The announcement came alongside reports that he had been targeted by Chinese intelligence. The available information provided no further details, leaving the claims—and their precise connection to his departure—unclear.
Huang has led Nvidia for many years. His reported departure adds a leadership transition to investors' assessment of the company's direction and future development.
