These are ARK Innovation ETF's own holdings, not the firm's. Percentages are of the stock positions in its latest filing — the fund's cash and bonds are not included. This exchange-traded fund aims for long-term growth of capital by putting the bulk of its money into companies working on what its manager calls "disruptive innovation" — technology-enabled new products or services that could change how the world works. Instead of sorting stocks by industry, it hunts across sectors for businesses tied to a handful of technology themes: artificial intelligence, the genomics and DNA-sequencing revolution, robotics and automation, energy storage, next-generation internet and fintech. It keeps those bets concentrated in a small set of names and holds them for a deliberately long horizon of about five years, betting that markets are underpricing a technology curve its analysts model as costs fall with production scale — a pattern the firm calls Wright's Law. The fund launched in 2014, the same year Cathie Wood left her post as chief investment officer of global thematic strategies at a large asset firm to start ARK Invest. She had pitched the idea behind it — actively managed funds built around disruptive innovation — to her then-employers, who turned it down as too risky. Wood, a Los Angeles–born manager who studied economics at the University of Southern California under Arthur Laffer, leads the fund today as its primary portfolio manager, overseeing the team organized by theme rather than industry. She rarely pushes companies to change course; she bets they will ride a technology curve that markets are underpricing.
