A story on the same day is not a cause, and a group move is not proof either. Group: the median of NVDA, AVGO, MU and AMD that day, the largest companies in AMKR’s SEC industry; “moved with AMKR” means the same direction and at least half the size.

AMKR against four chip peers, a year at 100

AMKR is up 93.3% in a year. Micron is up 5.9 times and Advanced Micro Devices 2.9. Of these four, NVIDIA (+30.4%) and Broadcom (+11.7%) did less. Weekly closes, Oct 10, 2025 = 100, on a log scale so a sixfold rise and a 11.7% rise both read honestly.
