Odaily Planet Daily News: Currently, the US stock market shows a stable and optimistic trend. The market is looking forward to Powell's speech at the Jackson Hole Economic Symposium to be held on Friday. Goldman Sachs outlined several key issues that it hopes Powell will address at the symposium in its report. The most important of these is to show confidence in the inflation outlook in his speech. Powell is expected to provide more dovish information than the press conference after the July FOMC meeting, and the Fed's policy interest rate will soon fall. (Jinshi)
