Tracked 13F institutions hold 52.1% of MAC's shares outstanding. This is a floor: 13F filings arrive on a ~45-day lag and we track only a subset of institutional filers, so true institutional ownership is higher. Shares-outstanding is the latest SEC cover-page figure (as of 2026-05-05), not a live float.
Ranked by estimated dollars moved (share change × implied price). 13F data lags up to 45 days.
