Peter Thiel's hedge fund Thiel Macro sold its entire positions in Apple and Microsoft during the fourth quarter. This goes against the general consensus since most analysts still see upside in both stocks. Apple reported 16% revenue growth driven by strong iPhone 17 sales in China. They also confirmed plans to use Google's Gemini models for Siri updates coming in 2026. Thiel likely sold due to the high valuation of 34x earnings and potential margin pressure from rising memory chip prices. Microsoft posted 17% revenue growth with strong momentum in Azure and Copilot. While the company is trading at a lower multiple than Apple at 26x earnings, some investors are worried about the return on investment regarding their massive AI spending.
