Conviction leaders · weighted by position size

Whose entire portfolio does smart money agree with?

30 managers ranked by the position-weighted average ConvictionScore of their top holdings. A high score means the unified −100..+100 smart-money model agrees with every one of their biggest bets, right now.

Forward-looking, not historical. Position-weighted so a +60 score on a 25% position counts more than +60 on a 2% position. “(Own)” holdings excluded.

How this is computed

Position-weighted average

weightedAvg = Σ(score × pct) / Σ(pct)

For each manager, every top-10 holding (excluding “(own)” companies like Icahn’s IEP) gets the unified −100..+100 ConvictionScore. We then average those scores weighted by the size of each position in the portfolio. A 25%-of-portfolio +60 conviction beats a 2% +60 conviction.

This is a forward-looking signal, distinct from /leaderboard (historical 10y alpha) and /manager-rankings (skill × activity composite). Average across all 30 leaders: −2.5.

ConvictionScore methodology: methodology. Not investment advice. Updates with each new 13F filing cycle.
