Portfolio weight, nothing exotic
For each manager, we take their top holdings as disclosed in the most recent 13F filing and compute three metrics:
- Top-1% — the portfolio weight of their single largest position
- Top-3% — the combined weight of their three largest positions
- Top-5% — the combined weight of their five largest positions
This is a static snapshot, not a time series. See /conviction-leaders for the position-weighted conviction ranking (different question: is the model bullish on their concentrated bets?).
Based on publicly filed 13Fs, which report long-only positions. Hedges and shorts are invisible. Not investment advice. Methodology.
