Catherine Wood (Trades, Portfolio) recently submitted the 13F filing for the fourth quarter of 2025, providing insights into her investment moves during this period. With over 40 years of experience, Cathie Wood founded ARK in 2014 to focus solely on disruptive innovation while adding new dimensions to research. Through an open approach that spans across sectors, market capitalizations, and geographies, she believes ARK can identify large-scale investment opportunities in the public markets resulting from technological innovations centered around DNA sequencing, robotics, artificial intelligence, energy storage, and blockchain technology.
