Decision Timeline

AMAT, decision by decision.

Not just who owns it now. This is the sequence of material choices managers reported, when each choice became visible, and the observed result after disclosure.

Material decisions

Trim / exit
5

The cohort disagreed in Q1 2026.

At least one tracked manager bought or added while another trimmed or exited. The disagreement is the signal; it is not collapsed into a consensus score.

Email me only when a reviewed weekly edition contains a material new decision about AMAT: a new position, exit, or a large share-count change that also clears the size threshold. There may be quiet weeks.

Confirm by email. Manage or stop follows in one click. See our privacy notice.

Material means a new or exited position, or at least a 20% share-count change, with at least 0.5% portfolio weight or $100 million reported value. Share counts are adjusted for confirmed splits. Outcomes start after disclosure, not at an invented trade date, and are not manager returns.
