Warren Buffett's Berkshire Hathaway is holding a record cash pile approaching $400 billion and has been a net seller of stocks for over three years. Concurrently, the "Buffett indicator," which compares the U.S. stock market to U.S. GDP, has reached an all-time high, recently topping 230%. This figure significantly exceeds the approximately 140% observed during the peak of the dot-com bubble in 2000, leading analyses to suggest that stocks appear expensive.
