Cathie Wood Dumps Roku Stock, Goes All-In on Biotech Bets - Here’s Why It Matters
Cathie Wood's ARK just made a massive pivot—dumping Roku positions while doubling down on biotech disruptors. The move signals a fundamental shift in her innovation thesis.
Roku gets the axe
Wood's funds slashed Roku exposure dramatically—catching many off guard. The streaming play once dominated her portfolios, but now gets sidelined for more explosive potential.
Biotech bets multiply
Gene editing, precision therapy, and AI-driven drug discovery stocks soak up the capital. Wood's betting that healthcare disruption will outpace streaming's growth—and she's putting serious money behind that conviction.
Wall Street shrugs—again
Traditional analysts question the timing—as they often do with her moves. But then again, these are the same folks who thought blockchain was just for crypto bros and AI was science fiction. Sometimes being early looks like being wrong—until it doesn't.

Another notable trade of the day was the addition of 119,163 shares of PagerDuty (PD), worth about $1.91 million. PagerDuty is a cloud-based incident management platform. Wood appears to be buying the dip in PagerDuty stock, as shares have been trending lower recently.
