At present, US stocks are showing a steady and optimistic trend, and the market is full of expectations for Powell's speech at the upcoming Jackson Hole Economic Seminar on Friday. Goldman Sachs outlined several key issues that Powell hopes to address at the seminar in its report. Most importantly, in his speech, he showed confidence in the inflation outlook. Powell is expected to provide a more dovish message than in the press conference after the July FOMC meeting. The Federal Reserve policy rate will soon decline.
