最新报道:U.S. stock market valuation has surpassed Warren Buffett's preferred overvaluation benchmark, with the total market cap now at 212% of GDP—far exceeding the 2000 dot-com bubble peak of 148%. This metric, which Buffett called "the best single measure" of market valuation, signals potential overheating as investors pour money into AI-related stocks and other tech sectors. The current ratio is nearly double the historical average of 107% since 1950, raising concerns among value investors about stretched valuations. However, some analysts argue traditional metrics may not fully capture today's digital economy dynamics, where tech giants drive disproportionate market growth.
