In the latest financial update, Cathie Wood’s ARK Invest has noticeably ramped up its investment in several key players from the so-called Magnificent 7, including Alphabet (GOOGL), Nvidia (NVDA), and Tesla (TSLA). While there are rising anxieties about the potential bubble in AI and uncertainties within the tech sector, Wood seems to be leaning further into these high-conviction stocks. All told, ARK’s 13F portfolio has expanded to $16.8 billion, now containing 196 different holdings.
