Markets muscled yet another winning week, led by a 3% rally from the RUT. The A.I. trade continued to dominate headlines, starting with Monday's announcement that Nvidia (NVDA) and AMD Inc. (AMD) will pay 15% of China chip revenue to the U.S. Intel (INTC) closed as the S&P 500's top performer of the week while CoreWeave (CRWV) sold off significantly after earnings. However, UnitedHealth (UNH) rallied big on Friday after Warren Buffett's Berkshire Hathaway bought millions of company shares. Marley Kayden takes investors through the trading week's biggest stories.
