Duquesne (Stanley Druckenmiller)
The Pittsburgh-born macro trader Stanley Druckenmiller (born 14 Jun 1953) and his firm, Duquesne Capital Management, which he started in 1980–81 with ~$1m of client accounts, ran alongside Dreyfus (1986–88) and George Soros's Quantum Fund (lead portfolio manager 1988–2000), and closed to outside money in Aug 2010 with about $12bn under management and a reported record of ~30% a year with no losing year — then continued as the Duquesne Family Office, whose quarterly 13F filings are the only public window on his trading since. He was the lead trader on Quantum's short-sterling trade of Black Wednesday, 16 Sep 1992 (a short of more than $10bn, profit usually given as ~$1bn — Shared facts, C04), and the man who in 1999–2000 went from short to long technology at the top and left Quantum after it fell ~22% in the first four months of 2000. His story is the book's case for concentration when right and cutting when wrong — and for how even that rule fails when a manager chases a trend he missed. All return figures are reported by the press from investor letters or Druckenmiller's interviews; none is audited (rule 4(c)).
At a glance
- Founded
- Duquesne Capital Management: 1980 with $1m in separate client accounts and a hedge-fund structure formalised in 1986 (Bloomberg, 28 Sep 2010, via InvestmentNews); 1981 per Wikipedia and the blueprint seed — conflict, give both
- Founder
- Stanley F. Druckenmiller — BA English and economics, Bowdoin College (1975); left a University of Michigan economics PhD to join Pittsburgh National Bank (1977) as a trainee, heading its equity research a year later (Wikipedia)
- Headquarters
- Pittsburgh (the firm's name is the city's Duquesne heritage — from memory, verify); New York (family office)
- Ownership / structure
- Private; outside hedge fund 1986–2010 (fees 1% and 20% — Bloomberg 2010); since 2010 a family office (Duquesne Family Office LLC, SEC 13F filer, CIK 0001536411)
- Scale (dated, reported)
- ~$2bn in 2000; ~$12bn at the Aug 2010 closure (Bloomberg 2010); family-office 13F long US equity and listed-option holdings $2.02bn (31 Dec 2022), $4.39bn (31 Mar 2024), $5.21bn (30 Jun 2026) (EDGAR, computed from the information tables; 13F shows only US-listed longs and option notional, not the whole portfolio)
- Record (reported, unaudited)
- Duquesne ~30% a year on average "since 1986" (Bloomberg) or for three decades, with no losing year (Reuters, Bloomberg, Wikipedia); 2008 ~+11%, 2009 ~+10% (Bloomberg 2010); 2010 down ~5% at the closure announcement (Reuters/Bloomberg), recovering to a small gain by year-end per Wikipedia (verify)
- Quantum role
- Hired by Soros in 1988 (replacing Victor Niederhoffer, per Wikipedia), lead portfolio manager 1988–2000; Bloomberg (2010) calls him chief strategist from late 1988 (Soros Fund Management)
- Regulators
- SEC (adviser registration while managing outside money; 13F filer); exit from outside capital in 2010 predated Dodd-Frank's repeal of the private-adviser exemption (effective 21 Jul 2011) and the SEC's family-office rule (Release IA-3220, 22 Jun 2011)
