Methodology & FAQ
How We Track DUMAC - Duke University Holdings
Our data is systematically aggregated directly from quarterly Form 13F-HR disclosures submitted to the U.S. Securities and Exchange Commission (SEC).
- Who Must File (Reporting Threshold): This dataset includes filings from U.S. institutional investment managers, hedge funds, mutual funds, university endowments, and family offices managing at least $100 million in qualifying discretionary U.S. equities.
- What is Included (Data Scope): We exclusively capture long equity positions and listed options (calls and puts) for DUMAC - Duke University. By SEC regulation, 13F filings do not require the disclosure of short positions, non-U.S. holdings, or OTC derivatives.
- Portfolio Weight Explained (Metric Definition): “Portfolio Weight” shows how much of a fund's total 13F U.S. equity portfolio is allocated to a specific position on the reporting date.
- How to Use This Data (Interpretation): Quarter-over-quarter changes in shares and portfolio weight reflect a combination of active trading and market price movements. These are descriptive metrics of fund allocation, not explicit buy or sell signals.
How do you measure hedge fund conviction in DUMAC - Duke University's portfolio?
We evaluate conviction by looking at portfolio weight rather than just absolute share count. A position that represents a large percentage of a fund's total 13F equity value signals high conviction, regardless of whether it ranks highly in absolute dollar terms. Tracking how this weight changes quarter-over-quarter helps distinguish active capital allocation from passive drift.
Does DUMAC - Duke University's 13F data include short positions or derivatives?
SEC Form 13F only mandates the disclosure of long U.S. equity positions and listed options (put and call contracts). Short interest, swaps, and OTC derivatives are excluded by regulatory design. To ensure accurate position scaling, listed options are reported based on their underlying share equivalent.
Are family offices and endowments included in this data?
Yes. Any institutional entity exercising investment discretion over at least $100 million in qualifying U.S. equities must file a Form 13F — this explicitly includes single-family offices and university endowments. If a qualifying entity holds positions reported by DUMAC - Duke University, their allocation is included in this dataset.
When is the data updated, and is there a reporting lag?
Institutional investment managers are required to file their Form 13F within 45 days after the end of each calendar quarter (the standard “T+45” window). Our platform processes filings immediately upon publication to the SEC EDGAR database, providing point-in-time consensus positioning without look-ahead bias.
