596 reporting institutions disclosed WCC position changes in the Q1 2026 snapshot. The largest disclosed owners include Wellington Management Group LLP, Dimensional, Invesco Ltd.. WhoBought does not publish a total institutional-ownership percentage for WCC: aggregate 13F filings can report the same shares more than once (a parent manager and its subsidiary filers, or shares out on loan), so a summed percentage would overstate what institutions really hold.
For each manager, WhoBought compares accepted consecutive 13F share counts. Share change is current shares minus prior shares. Estimated dollar change is that signed share change multiplied by the split-adjusted quarter-mean close. The activity table on this page uses Q1 2026.
An investor crossing 5% of a share class generally files Schedule 13D for activist intent or Schedule 13G for a passive position. The technical form names appear here rather than in the activity rows.
Ownership and institutional activity come from SEC Form 13F filings. Insider activity comes from SEC Form 4, and large-shareholder activity from SEC Schedules 13D and 13G. FMP supplies price data only. Company logos use the local verified Parqet cache with one shared fallback.
Form 13F is a quarterly disclosure and is normally filed after the quarter ends. Every ownership and activity value therefore names its represented period; it is not presented as a live position.
A muted dash marks a missing table value. It means the filing omitted the value, comparable data is unavailable, or no prior position exists for comparison.
