Smart Money Ownership

Of the 9 tracked institutions holding LB, 3 have a 3-year clone track record — 3 of them beat the S&P. Average holder's clone alpha: +7.1pt. 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 →
