AI Holders Summary · Q2 2026

Assenagon Asset Management, Alcoa's largest tracked institutional holder, cut its position by 90.9% this quarter — from 493,756 shares down to just 44,899 — during a stretch when the data implies AA's share price fell roughly 21.4%. Even after that near-total retreat, Assenagon still ranks as the largest holder in AA's thin $6.1 million tracked institutional book, at 38.3% of the total, underscoring how much its prior position dominated the stock's tracked ownership. Not every holder read the decline the same way: Shelton Wealth Management, LLC added to its stake even as the price fell, growing its position 34.8% (10,520 to 14,186 shares) to become the third-largest holder at 12.1% of the book. Davenport & Co LLC also added shares (+11.7%) even though the price drop meant its position's dollar value still declined. Four new holders opened positions this quarter, led by Curated Wealth Partners LLC ($300,179, 80,432 shares).

Alcoa Corp (AA) shows $6.1 million in tracked institutional value across 29 holders as of the quarter ended June 30, 2026 — a small sample where a single holder's decisions carry outsized weight. That holder, Assenagon Asset Management S.A., cut its position by 90.9% this quarter, from 493,756 shares to just 44,899. The scale of that prior position — implied at roughly $32.7 million based on the per-share pricing embedded in the data — was itself many times larger than AA's entire current tracked institutional book, which shows just how dominant Assenagon's holding had been before this quarter's sell-down.
