On the evening of August 29, Beijing time, the United States announced that the year-on-year growth rate of the core PCE price index for July was 2.9%, which was basically in line with expectations and higher than the previous value of 2.8%. Earlier, on the 22nd, Powell unexpectedly adopted a dovish stance at the Jackson Hole annual meeting, significantly increasing market bets on a rate cut in September, which reignited the U.S. stock market rally, with the S&P 500 and Dow Jones Industrial Average both setting new closing highs on the 28th. Will the core PCE index for July strengthen expectations for a rate cut in September again? How will the U.S. stock market start in September?
