How these numbers are made
- Source: Form 13F-HR reports and their amendments (13F-HR/A) on SEC EDGAR. Holdings are read from the XML information tables of the reports. Those exist from the quarter to June 30, 2013; older reports are plain text and are not used here.
- Values were reported in thousands of dollars until the SEC’s change of January 3, 2023, and in dollars since; all are shown in dollars. Each report is checked by its value per share. This investor’s reports filed from May 15, 2023 to Aug 14, 2026 were still in thousands of dollars and are read that way.
- A stock often takes several lines of a report, one per subsidiary or adviser that holds it. The lines are added up by CUSIP, the security’s identifier; options are kept apart.
- Amendments are applied in the order they were filed: a restatement replaces the quarter’s report, “new holdings” adds positions that had been kept confidential.
- Moves compare every holding with the previous report. After a stock split the earlier share count is converted to the new basis (splits of S&P 500 companies from their SEC filings, others from the value per share). The dollar amount of a move is the change in shares times the quarter-end price, so it only approximates what was paid or received.
- A stock whose CUSIP changes (after a merger or a reorganization) shows as sold under the old CUSIP and bought under the new one.
- Tickers come from the SEC’s fail-to-deliver data. A holding links to a company page here only when its CUSIP belongs to that S&P 500 company.
- Positions first reported in an amendment: Affirm Holdings (Q1 2021, reported Nov 17, 2021); Oscar Health (Q1 2021, reported Nov 17, 2021); Coupang (Q2 2021, reported Nov 17, 2021); Affirm Holdings (Q2 2021, reported Nov 17, 2021); Oscar Health (Q2 2021, reported Nov 17, 2021).
- Checked every night. Reports are due 45 days after each quarter ends: in mid-February, May, August and November.
- Not investment advice: by the time a 13F is public the position may be gone, and it is only part of what the investor owns.
