Methodology
Form 13F is the SEC's quarterly disclosure for institutional investment managers exercising discretion over $100 million or more in qualifying U.S. equity securities. Managers must file within 45 days of each calendar quarter end, which is why holdings shown here reflect a snapshot at the period date — not real-time positioning.
Quarter-over-quarter deltas compare each manager's most recently reported share count for PMCB against its prior-quarter count. New positions are entries where the prior count was zero; closed positions are entries where the current count is zero. Amendments (13F-HR/A) replace prior filings for the same period.
Source: SEC EDGAR Form 13F (XML information tables). Dollar values are as reported by the manager and may use mid-quarter pricing conventions. CUSIP-to-ticker resolution is best-effort.
