Is this a fund anyone can invest in?

No. Duquesne returned all outside money in 2010 and is a family office. It files a holdings report because of the size of its US share positions, not because it takes clients.

Why is the portfolio so concentrated?

Druckenmiller has said for years that he prefers a few large positions to many small ones. The latest filing holds around 90 names, and the top handful carries much of the value.

How quickly does it change?

It changes quickly. Positions are often opened and closed within a few quarters, so one filing shows only what he held on one day.

SourceSEC Form 13F filings (US)Holdings as of 30 Jun 2026

The +48.6% above is the 12-month change these weights would have produced. It is not Duquesne Family Office's return.

Why people follow this portfolio

Duquesne Family Office manages the wealth of Stanley Druckenmiller. These are the US-listed positions from its latest filing.

Stanley Druckenmiller ran Duquesne Capital for 30 years without a losing year, and traded alongside George Soros at Quantum. He returned his investors' money in 2010 and said the pressure of managing it had become too much. The family office that replaced the fund still files a quarterly report, because it holds more than 100 million dollars in US-listed shares.

The portfolio is small enough to review in full. Around 90 positions appear in the latest filing, and the largest few carry much of the value. Druckenmiller changes positions quickly and in public: a company can be a top holding one quarter and be out of the portfolio two quarters later. He has described that as part of the method rather than as a flaw.

His best-known trades were never in shares. Currencies, interest rates and index positions do not appear on this form, so a reader sees only the equity portion of a much wider set of positions.

Where this data comes from

Positions come from the 13F form the family office files with the SEC each quarter. The form covers US-listed shares and options on them, so currencies, bonds and non-US holdings do not appear. A short sale of shares does not appear either.
