Major investment firms suffer significant declines following the launch of Hazel, an innovative AI application capable of designing personalized investment strategies in minutes. Hazel, developed by the U.S. platform Altruist, has disrupted the financial sector by allowing advisors to analyze tax documents, pay stubs, and minutes to create tailored investment plans for each client. Additionally, the tool can simulate scenarios such as asset sales or retirement, optimizing decision-making. Jason Wenk, founder and CEO of Altruist, emphasized that Hazel "enhances advisors' capabilities, improves outcomes, and makes it difficult to justify traditional advice." The announcement has raised concerns among investors, who fear that AI may displace conventional wealth management models. The impact was immediate: on Tuesday, major U.S. firms already reported declines, and on Wednesday, the reaction spread to British firms. St. James’s Place, a leader in the UK, plummeted by 13.39%, while AJ Bell lost nearly 8%. Aberdeen and Quilter fell by more than 5%, and Julius Baer and UBS limited their losses to 3%. This wave of selling reflects investors' concerns about potential AI disruption, similar to what was recently experienced in the tech sector following the launch of new tools from Anthropic. Paul Manduca, chairman of St. James’s Place, described the reaction as "exaggerated," defending the relevance of personal advice and the use of AI as support. Steven Levin, CEO of Quilter, highlighted the growth potential of the UK market and his firm's commitment to technology to enhance productivity. AJ Bell sees AI as an opportunity to optimize the experience for clients and advisors, using GenAI in customer service. Analysts from Panmure Liberum noted that automated advice is not new and that purely robotic models have not succeeded so far. The launch of Hazel has propelled Altruist, valued at $1.9 billion in April after a round led by GIC, Singapore's sovereign wealth fund. In the U.S., Schwab and Raymond James closed on Tuesday with declines of 7.4% and 8.7%, respectively, while Stifel Financial and Morgan Stanley also experienced drops. These sales add to the pressure felt on Wall Street the previous week when the announcement of new AI tools from Anthropic for Claude Cowork caused significant declines in software companies. Fears of technological disruption intensified after the announcement that OpenAI will integrate an insurance provider into ChatGPT, leading to declines in brokers like Willis Towers Watson, Aon, and Ryan Specialty. The tech sector, far from slowing down, continues to invest in AI: Alphabet, Amazon, Meta, and Microsoft have announced joint investments of $660 billion in the development of this technology in 2026.
