Sept 13 (Reuters) - Wall Street's main indexes rose on Friday as investors reevaluated the possibility of a bigger interest rate cut by the Federal Reserve week, while Photoshop maker Adobe tumbled after forecasting fourth-quarter earnings below estimates.
Traders' bets of a 50-basis point rate cut jumped overnight, standing at 47% compared with 14% on Thursday, CME's FedWatch Tool showed.
Former New York Fed President Bill Dudley said there was a strong case for a 50-bps interest rate cut. Separate media reports calling the decision "a close call" also added to the uncertainty.
"A couple of articles were published in the Wall Street Journal and the Financial Times suggesting that a 50-bps move was still in play, which has led markets to once again reevaluate their expectations," Deutsche Bank analysts said.
Bets of the Fed sticking to a smaller 25-bps cut had firmed on Thursday following a slightly higher producer prices report that followed the August consumer prices data.
"Markets want the FOMC to ease fast and get on with the risk of recession fighting. The meeting is a risky event and it will remain so regardless of the 25 or 50 bps easing week," said Bob Savage, head of markets strategy and insights at BNY Mellon.
