币界网报道：The Dow Jones Industrial Average surged over 300 points on Tuesday as investors grew optimistic about potential Federal Reserve rate cuts following cooler-than-expected inflation data. The blue-chip index climbed 1.1% to close at 39,110, marking its best day since May. The rally came after the Labor Department reported the Consumer Price Index (CPI) remained flat in May and rose just 3.3% annually, below economists' forecasts. Treasury yields fell sharply, with the 10-year note dropping below 4.3%, as traders priced in higher odds of at least one Fed rate cut this year. Small-cap stocks outperformed, with the Russell 2000 jumping 2.5%. Market participants now see a 67% chance of a September rate cut, up from 50% before the CPI release, according to CME Group's FedWatch tool. The S&P 500 gained 1.3% and the Nasdaq Composite rose 1.5%, with technology stocks leading the advance. Financial markets have been volatile in recent weeks as investors recalibrate expectations around the Fed's policy path amid mixed economic signals.
