Billionaire Stan Druckenmiller Shaves $660 M Off His Book And Jumps Into These Stocks

view original post

After 30 years of delivering 30% annual returns on average, Stanley Druckenmiller shuttered his hedge fund Duquesne Capital in 2010, when the global macro trade came under pressure. Rather than retire, Druckenmiller launched his own home office, the Duquesne Family Office, which he continues to run today. The office oversees about $3.06 billion in assets under management (AUM) as of Q1 2025, down from approximately $3.7 billion across dozens of stocks at the end of 2024—a decline of about $660 million, reflecting Druckenmiller’s active trading.

Stan Druckenmiller is known for making bold moves, particularly with Big Tech stocks related to artificial intelligence. Recent quarters have been no exception. According to the Q4 2024 13F filing, the Duquesne Family Office sold nearly 43,100 shares of Microsoft and close to 240,000 shares of Broadcom, liquidating its position in both stocks. In 2025, Druckenmiller has also traded actively in sectors such as technology and pharmaceuticals, among others.

The Q1 2025 13F filing reveals that the Duquesne Family Office sold out of numerous stock positions and sharply reduced holdings in others, lowering the portfolio value. Additionally, Q1 2025 experienced a downturn in the U.S. stock market, including a 4.2% decline in the S&P 500 and 10.3% drop in the tech-heavy Nasdaq Composite. Magnificent Seven stocks, including Tesla (Nasdaq: TSLA)—one of Druckenmiller’s holdings—got off to a rocky start in 2025, further diminishing the overall portfolio value in the first quarter.

Here is a look at Druckenmiller’s largest trades so far in 2025, according to public filings.

Top Sells

• In Q1 2025, Duquesne Family Office reduced its stake in Seagate Technology Holdings (Nasdaq: STX) by $114 million. Hedge fund Duquesne Capital, under Druckenmiller, first bought STX stock in Q3 2009. The firm later exited the position in Q4 2009 but re-established a stake in Q4 2010 under Duquesne Family Office. Druckenmiller has traded in and out of the stock multiple times since then, including its most recent sell trade. STX stock is currently trading near the higher end of its 52-week range.
