On May 15, an important deadline passed for institutional investors managing over $100 million in assets, requiring them to file Form 13F with regulators. This date also coincided with Jerome Powell’s final day as chair of the Federal Reserve.
In the wake of this deadline, Stanley Druckenmiller, head of Duquesne Family Office, emerged as a key figure in financial news. As one of the most closely watched billionaire money managers on Wall Street, Druckenmiller made headlines by completely divesting his stake in Alphabet, the parent company of Google. His 13F filing revealed that he sold all 385,000 shares of Alphabet’s Class A stock during the first quarter, prompting considerable interest and speculation among investors.
Druckenmiller’s decision to sell could be attributed to profit-taking strategies. Managing an active fund with an average holding period of around eight months, Druckenmiller has a history of cashing in on profitable investments. Since he held Alphabet shares, their value appreciated significantly—over 50%—making the sale a logical move.
Additionally, there are indications that Druckenmiller may have viewed Alphabet’s soaring valuation as concerning. After experiencing a remarkable 140% rise over the last year, the stock’s price multiples changed dramatically, with its future earnings now trading at nearly 28 times expected EPS—up from under 17 times just a year prior. Druckenmiller has also previously expressed skepticism about the hype surrounding artificial intelligence stocks, implying that he might have considered Alphabet’s growth unsustainable.
In contrast, Druckenmiller demonstrated a strong interest in memory and storage stocks, significantly increasing his holdings in companies such as Sandisk, Micron Technology, and Seagate Technology. His portfolio now includes over 38,000 shares of Sandisk, approximately 50,700 shares of Seagate, and around 23,400 shares of Micron.
Despite his hesitance towards AI stocks, Druckenmiller’s commitment to memory and storage companies appears to stem from the growing demand for high-capacity hard drives and other critical components as data center infrastructure expands to accommodate AI workloads. This escalating demand has led to considerable price hikes and margins for these companies.
Interestingly, even after significant price increases—3,370% for Sandisk and 660% for Micron over the past year—both stocks remain relatively undervalued, trading at forward price-to-earnings ratios of just 8 and 7, respectively. Given these valuations and the intense demand for the technology they produce, Druckenmiller seems poised to capitalize on what he believes are short-term trading opportunities, confidently navigating through the complexities of the stock market.
