Thirty-seven of the top-200 alpha cohort initiated $AMAT positions in Q1 2026, with two more adding to existing stakes and none exiting — a configuration that is, structurally, about as one-directional as these filings get. The cohort now counts 57 holders total, up from 20 the prior quarter.
Coatue Management LLC carries the largest weight at 6.17% (+2.33pp quarter-on-quarter), the single most conviction-weighted position in the cohort. Stelac Advisory Services LLC added aggressively as well, moving from 0.19% to 1.50% (+1.31pp). Among initiators, Delta Financial Advisors LLC opened at 2.78% and BNP Paribas entered at 1.92% — both meaningful first positions relative to the cohort's average.
The cohort-average weight across all 57 holders sits at 0.61%, with a range of 0.00% to 6.17%. That spread reflects a familiar pattern: a handful of high-conviction holders pulling the top of the range well above the median, while the bulk of initiators entered at sub-0.30% weights. Vista Investment Partners LLC (2.68%) and Fruth Investment Management (1.67%) represent the steadier mid-tier, both held with modest positive drift from Q4 2025.
Thirty-seven new initiations in a single quarter is a large cohort expansion for one name. Whether that reflects index-rebalancing mechanics or genuine fresh conviction is not answerable from 13F data alone; what the filings show is that no holder in this cohort reduced or exited, which is the cleaner half of the signal.
