Quarterly snapshots, scoring and coverage
Top buys and new positions count distinct managers in Q2 2026; an addition is a reported net share increase, not a known trade. A newly reported holding can also result from a spin-off or other corporate action. Counts cover stocks in this catalog and exclude managers outside the comparison cohort. Latest included filing: 2026-09-02. Other reporting quarters are excluded from these activity counts. New-position and exit totals count manager–stock pairs.
The existing Cohort Conviction Score combines breadth (25 points), concentration (25), net activity (15), holding tenure (15) and historical cloned-portfolio performance versus SPY (20). It uses the latest available holdings across its own cohort, which may span reporting quarters. A score is not a probability of success, a valuation or a buy recommendation. Scoring methodology →

Evidence before conviction.
01 / Know what is reported
Selected, dated records from Latticework’s editorial decision ledger. Changes use reported share counts, with the existing split adjustment; weights describe a manager’s disclosed long 13F book. No purchase price is inferred.
02 / Challenge the interpretation
Research questions and risks come from existing reviewed company briefs, with AI assistance labeled. Investor motives remain unknown without an attributable statement. Neither selection nor portfolio weight establishes undervaluation.
03 / Keep the limits visible
Quarter-end reports arrive after the period they describe and omit shorts. This is selected coverage, not a complete investor portfolio or current recommendation. Save uses your existing browser list; it does not subscribe you to email.
