Stanley Druckenmiller is known for taking significant wagers.
At 72, this billionaire famously advised to “bet the ranch” on opportunities that seem particularly promising.
As the tech-heavy Nasdaq Composite has dropped around 2% year-to-date, his recent investment decisions might provide insights for investors.
Druckenmiller, previously a key figure for George Soros, played a major role in the infamous 1992 trade against the British pound that “broke the Bank of England.”
He established Duquesne Capital Management in 1981, managing it until its closure in 2010, achieving an average yearly return of 30% over nearly thirty years.
After closing Duquesne Capital to external investors, he shifted to managing his wealth through a family office, now known as Duquesne Family Office, which recorded a 37% return over the past year and 123.25% over five years, based on information from Stockcircle.
In the fourth quarter of 2025, Druckenmiller made significant investments in large-cap tech companies, enhancing his Amazon (AMZN) stake by 68.8%, increasing his position to about 300,870 shares valued at around $63 million. This investment makes Amazon the seventh-largest in his portfolio.
