Notable moves
Names where the tracked-fund universe broadened or narrowed between 2025-Q4 and 2026-Q1, by change in the number of funds holding each. Holder counts are split-invariant, so a stock split never reads as a wave of new buying.
In 2026-Q1, AZN drew the most new institutional holders (+1262 funds) and AZNN was left by the most funds (−1293) among the funds we track. This describes the change in how many funds hold each name — not a view on the stock.
