最新报道:U.S. stocks surged to record highs, with the S&P 500 surpassing 5,000 for the first time amid strong earnings and economic optimism. The rally, fueled by tech giants like Nvidia and Meta, has sparked concerns of a potential market bubble as valuations stretch. Analysts note parallels to past bubbles but highlight differences, including robust corporate profits and AI-driven growth. Investors remain divided, with some cautioning against overexuberance while others see room for further gains. The Fed's potential rate cuts later this year add to the bullish sentiment, though inflation data remains a key watchpoint.
