Buffett Poured $35B Into 1 Stock — The Bet Nobody Caught

Warren Buffett poured $35 billion into a single stock — and the real reason why went completely over most people's heads. At its peak, Apple represented over 40% of Berkshire Hathaway's entire public equity portfolio. One position. Nearly half the book. From the same man who spent decades telling retail investors to spread their risk. So what was Buffett actually seeing that Wall Street analysts kept missing while they were busy arguing about iPhone upgrade cycles and supply chain bottlenecks?
