Methodology & FAQ

How We Track Commodore Capital 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 Section 13(f) securities (including equities, options, convertibles, ETFs, and warrants).
  • What is Included (Data Scope): By regulation, 13F filings include long positions in U.S. exchange-listed stocks, ETFs, shares of closed-end investment companies, and convertible debt, as defined in the SEC's official Section 13(f) securities list . For listed options (calls/puts) the reported value is based on the notional value.
  • Portfolio Weight Explained (Metric Definition): “Portfolio Weight” shows how much of a fund's total reported 13F portfolio value (excluding listed options) 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.
What does Commodore Capital's 13F filing disclose about their portfolio?

A Form 13F-HR filed by Commodore Capital with the U.S. SEC discloses all long positions in Section 13(f) securities — U.S.-listed equities, ETFs, closed-end funds, and listed put/call options — held at quarter-end with a market value of at least $200,000 or 10,000 or more shares. Pactolio aggregates these filings to surface Commodore Capital’s reported portfolio weights, share counts, and quarter-over-quarter allocation shifts in a structured format. The filing represents a point-in-time snapshot of disclosed long-side exposure, not a real-time or complete view of the fund’s total book.

How do you measure conviction in Commodore Capital's portfolio allocations?

Conviction is measured by portfolio weight — the percentage of Commodore Capital’s total reported 13F market value allocated to a given position — rather than by absolute share count or dollar value alone. A position representing a disproportionately large share of the fund’s disclosed book signals high-conviction allocation, regardless of whether it ranks among the fund’s largest absolute holdings. Tracking how that weight changes quarter-over-quarter separates active reallocation decisions from passive price appreciation drift.

What is excluded from Commodore Capital's 13F — short positions, swaps, and derivatives?

SEC Form 13F requires disclosure of long positions only. Specifically excluded are: short interest, total return swaps, credit default swaps, and all OTC derivatives — none of which appear in 13F filings regardless of position size. Listed put and call options must be disclosed but are excluded from portfolio weight calculations on this platform so that reported weights reflect direct equity exposure and remain comparable across filers. This means Commodore Capital’s 13F represents the reported long book, which may differ materially from its net economic exposure.

When is Commodore Capital's 13F data available, and how large is the reporting lag?

Investment managers must submit Form 13F within 45 calendar days of each quarter-end (the T+45 deadline). Pactolio ingests filings directly from SEC EDGAR as they are published — managers who file early appear in our system before the deadline, while late filers are captured on their actual filing date. The quarter label shown at the top of this page reflects the most recently processed 13F cycle for Commodore Capital. The inherent reporting lag means the data always reflects positions as of the prior quarter-end, not current holdings.

Who must file a Form 13F with the SEC, and does Commodore Capital qualify?

Under SEC Rule 13f-1, any investment manager — including hedge funds, family offices, registered investment advisers, pension funds, and university endowments — that exercises investment discretion over $100 million or more in Section 13(f) securities at any point during a calendar year must file Form 13F for that year. Commodore Capital meets this threshold, which is why its holdings are publicly disclosed and accessible on this platform. The $100 million threshold is evaluated on a rolling basis, meaning new filers can enter and existing filers can exit the disclosure regime as AUM crosses that boundary.
