Wall Street's main indexes climbed as much as 2% Friday after U.S. Federal Reserve Chair Jerome Powell pointed to a possible interest-rate cut at the central bank's next policy meeting during his Jackson Hole Symposium speech.
Powell's comments opened the door to a rate cut at the Fed's September 16-17 meeting, but also underlined the importance of the jobs and inflation data that will be available by then.
"Chair Powell was able to talk about the balance of risk shifting and therefore the potential... shifting of policy would be appropriate," said Art Hogan, chief market strategist at B Riley Wealth.
"Leaning into the fact that the labor market weakness is clearly the driver, as opposed to concern over the core goods price increases that we've seen because of tariffs... the clear message to the market is September is now very live."
Traders boosted bets on a September rate cut after Powell's comments, now placing a nearly 90% probability on a reduction, versus about 75% before Powell's remarks.
