Of the 11 tracked institutions holding PRAX, 3 have a 3-year clone track record — 3 of them beat the S&P. Average holder's clone alpha: +2.8pt. It's a gauge of who owns the name, not just how many.
Alpha = the manager's 3-year clone return minus the S&P 500. A skilled roster is a stronger tell than a crowded one — though even skilled managers' edge doesn't reliably survive the 13F disclosure lag. Why →

Tracked 13F institutions hold 38.2% of PRAX'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 2026-05-04), not a live float.
Ranked by estimated dollars moved (share change × implied price). 13F data lags up to 45 days.
