Druckenmiller bets big on Natera, Insmed in latest portfolio

Legendary investor Stanley Druckenmiller has just revealed his latest stock moves, and megacap tech isn’t on the shopping list. In his $3 billion Duquesne Family Office portfolio, Druckenmiller held only one of the so-called “Magnificent Seven” stocks—Amazon—and even slashed that position by nearly 700,000 shares in the first quarter. He also completely exited Alphabet, selling every share he owned. This marks a clear tilt away from the biggest U.S. tech names that have driven market gains in recent years.

Druckenmiller, whose Duquesne Capital once delivered 30% annual returns over three decades without a single losing year, has continued to outperform even after closing the hedge fund in 2010. His family office has returned roughly 393% over the past decade, beating the S&P 500’s 251% gain. His latest 13F filing suggests he’s hunting for value beyond the usual tech giants, focusing instead on smaller, high-conviction bets. This shift comes as investors debate whether the dominance of a handful of mega-cap tech stocks can continue amid rising interest rates and geopolitical uncertainty.

The portfolio’s largest holding is Natera, a cell-free genetic testing company focused on women’s health and oncology. Druckenmiller increased his stake by 22% in Q1, making it a 21% chunk of the entire fund. He also loaded up on STMicroelectronics (3% of the portfolio) and Taiwan Semiconductor Manufacturing (5.7%), though he trimmed the latter slightly. Among new or expanded positions are AI-linked names like Micron, Intel, and Arm Holdings, but none exceed 1% of the total. The second-biggest holding is Insmed, a biopharma play in rare diseases, which he pared back by 22% but still accounts for 6.4% of assets. Druckenmiller also made a bold bet on YPF, an Argentinian oil and gas company, adding 2.6 million shares in Q1.

What happens next matters not just for Druckenmiller’s investors, but for the wider market. His avoidance of megacap tech—while doubling down on biotech, semiconductors, and even an emerging market energy play—signals a bet on diversification and undervalued opportunities outside the usual winners. If his strategy pays off, it could encourage others to look past the crowded tech trade. If not, it may reinforce the staying power of the big seven. Either way, Druckenmiller’s moves offer a rare glimpse into one of the sharpest minds in investing.
