Methodology
Holder IQ
Measuring institutional skill from 13F filings so you can see when high-IQ managers are accumulating, trimming, or exiting your positions.
What is Holder IQ?
A skill score (0-100) for institutional managers derived from 13F filings. We measure whether the funds holding a stock historically add alpha after controlling for market and style factors.
Data Pipeline
- Ingest all 13F filings via SEC EDGAR within minutes of posting
- Normalize CUSIP/ISIN to tickers; join to our securities master
- Track quarterly position deltas (entries, adds, trims, exits)
- Forward returns window: 1, 3, and 6 months after each filing
- Factor-adjust returns using our 18-factor model (Barra-inspired)
Scoring Formula (per manager)
We compute alpha on each disclosed position, aggregate by manager, then convert to a percentile-based score.
- Alpha Percentile (35% weight): risk-adjusted forward return vs. peers
- Win Rate (20%): share of positions with positive factor-adjusted return
- Sharpe (20%): return per unit volatility on disclosed positions
- Consistency (15%): lower variance of alpha across quarters
- Crowding Penalty (10%): discount if holdings are heavily crowded
Security-Level Signals
- Holder IQ Score: weighted average of top-decile managers holding the stock
- Momentum: net shares added/trimmed by high-IQ managers last quarter
- Entry/Exit Pressure: count of top-decile entrants vs. exits
- Crowding: percentile of institutional ownership vs. peers
Aggregation Logic
- We only include managers with ≥8 quarters of history and ≥15 holdings
- Scores are liquidity-adjusted (larger, more liquid names weigh more)
- Recency weighting: last 2 quarters = 60% of score
- Sector/Style neutrality to avoid over-crediting category beta
Limitations & Caveats
- 13F is T+45 days: signals are delayed vs. real-time trades
- No short positions in 13F; we treat exits as neutral unless high conviction
- Non-US and derivatives exposure not captured
- Extreme portfolio turnover can inflate win rate; mitigated via consistency weight
