Where does this portfolio data come from?

This data is sourced from SEC 13F-HR filings submitted to EDGAR. Fund managers with over $100 million in qualifying assets are required to disclose their long equity positions within 45 days of each quarter end.

How often is this portfolio updated?

Quarterly. Each 13F-HR filing covers one quarter-end snapshot and is due to the SEC within 45 days after the quarter closes (e.g., by May 15 for Q1). Tracefour updates automatically when a new filing appears on EDGAR.

Does this show all of the manager's positions?

13F filings cover U.S.-listed equities, options, and convertibles valued above $10,000, long positions only. They do not include short positions, foreign-listed securities, private equity, bonds, cash, or futures.

Yes. All data is sourced from public SEC EDGAR filings. There is no subscription or paywall on Tracefour.

Duquesne Family Office

Chairman & CIO · former lead manager of the Quantum FundRan George Soros’s Quantum Fund from 1988 to 2000, including the 1992 sterling trade, and his own Duquesne Capital from 1981 until he returned outside capital in 2010. Duquesne Family Office now manages his own money and files a quarterly 13F. The book is far wider than a typical concentrated manager, at 95 names as of June 30 2026, and turns over heavily between quarters.

What this view can't show you

45-day disclosure lag: positions are reported up to 45 days after each quarter ends; the manager may have rotated by the time you see them.
Long-only disclosure: short positions are not reported. Puts are shown at notional, not the premium paid.
Options excluded from the % line: the performance line tracks the disclosed stock holdings only; puts and calls are left out. Long calls still count toward the portfolio-value figure and the allocation donut; put notional is excluded from both.
Disclosed value ≠ performance: growth in disclosed value reflects market moves, new investor capital, and new buys; it is not pure returns.
Index caps each position at 30%: the performance line holds no single name above 30% (the rest as cash), so one outsized pick can’t dominate the return. The allocation donut shows the true disclosed weight, which may be higher.
