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 ALAB’s SEC industry; “moved with ALAB” means the same direction and at least half the size.

Six trading days after each results filing (SEC 8-K, Item 2.02). ALAB reports after the close, so day 1 is the next close. 2 of 4 times, day 6 ended on the same side as day 1.

ALAB against four chip peers, a year at 100

ALAB is up 75.7% 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.
