Cathie Wood’s ARK Invest recently made some changes to its portfolio, buying shares of Tempus AI while selling off Exact Sciences. Tempus AI is a company known for its artificial intelligence technology in the healthcare industry, which could potentially drive growth for ARK in the future. On the other hand, Exact Sciences is a company that focuses on cancer screening tests, but ARK seems to have decided to part ways with this stock. It will be interesting to see how these moves will impact ARK’s portfolio in the coming months.
