Value and % of AUM are this fund's own disclosed long-equity book (13F does not report true firm AUM). Positions is the fund's total position count (all tickers, not just JBIO). Qtrs Held counts distinct quarters this fund has actually held JBIO (weight > 0), across every period we've rescored. Fund AUM and Positions filters apply to the fund's whole book, not its JBIO position size. Δ columns are the percentage-point change in JBIO's weight within each fund's book vs. the trailing 1/2/3/4 quarters (2025Q4 / 2025Q3 / 2025Q2 / 2025Q1) — a fund not yet holding it that far back is treated as 0%. Only in-universe (quality-scored) funds are shown, matching the Signals-tab methodology.
