The Buffett indicator, which compares total U.S. stock market capitalization to gross domestic product, has reached 236%, far above the 200% level that Warren Buffett once warned means investors are 'playing with fire.' Buffett explained in a 2001 Fortune article that the ratio of the market caps of all publicly traded companies to U.S. gross national product had reached 'an unprecedented level' by late 1999 and early 2000, a warning signal before the dot-com crash. Gross domestic product, which measures economic output within the nation's borders, was later substituted for GNP. Meanwhile, Berkshire Hathaway's cash and short-term investments have swelled to over $397 billion, the highest in the company's history and the largest cash position of any U.S. company ever, signaling that Buffett and CEO successor Greg Abel see most stocks as too expensive. Buffett recently told CNBC that 'it's tough to find values when everybody is preferring gambling,' and Berkshire has been a net seller of stocks for 14 consecutive quarters. Despite these cautionary signs, the indicator can remain elevated for extended periods, and stock market bubbles can take longer to burst than many expect.
