AMD Soars 13% in Best Session in Six Months While Nvidia Slips 4% on Board Probe Report

Advanced Micro Devices jumped 13.26% to $508.58 on Monday, its best session in six months, after Oppenheimer upgraded the stock to Outperform. AMD's EPYC processor was also named the host CPU for Google Cloud's TPU 8tx.

Nvidia moved the other way, falling 4.27% to $178.67 on news of a board probe into CEO Jensen Huang. The split highlighted how quickly leadership in the AI chip trade can shift.

The moves followed a sharp chip-sector selloff last week and helped drive Monday's broad technology rebound, with implications for AI hardware suppliers across the market.
