What is WMK institutional ownership?
This page tracks WMK positions reported by institutional investment managers through SEC Form 13F. WEIS MARKETS INC (WMK) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own WMK?
InsiderSet currently tracks 193 institutional managers reporting WMK holdings in the latest available 13F data. This count reflects institutions included in the SEC Form 13F filings analyzed by InsiderSet and should not be interpreted as the total number of WMK shareholders.

The latest WMK institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
