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 next week, while

Photoshop maker Adobe tumbled after forecasting fourth-quarter

earnings below estimates.

Traders' bets of a 50-basis point rate cut jumped overnight,

now 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 next week," said

Bob Savage, head of markets strategy and insights at BNY Mellon.

All major U.S. benchmarks had closed higher in the previous

session, boosted by rising megacap stocks, keeping them on track

for weekly gains.

The Dow Jones Industrial Average rose 229.80 points,

or 0.56%, to 41,326.57, the S&P 500 gained 21.06 points,

or 0.37%, to 5,616.51, and the Nasdaq Composite gained

54.40 points, or 0.31%, to 17,624.08.

The economically sensitive Russell 2000 small cap index

was up 1.5%.

Ten of the 11 S&P 500 sectors inched higher, led by a 0.9%

rise in materials stocks that tracked an increase in

the prices of precious metals.

The Philadelphia SE Semiconductor index rose 1.3% to

levels last seen on Sept. 2, with most chip stocks trading

higher.

Meanwhile, a preliminary reading of the University of

Michigan's September consumer sentiment index stood at 69

compared with analysts' estimates of 68.5.

Among individual movers, Boeing ( BA ) fell 2.6% as its U.S.

West Coast factory workers walked off the job early on Friday

after overwhelmingly rejecting a contract deal.

Adobe slid 9% after forecasting fourth-quarter

earnings below analysts' estimates, while Oracle jumped

2.7% after the cloud computing company raised its fiscal 2026

revenue outlook.

Chinese e-commerce firm PDD Holdings ( PDD ) dropped 2.4%

after the Biden administration said it was moving to curb

low-value shipments entering the U.S. duty-free under the $800

"de minimis" threshold.

Uber ( UBER ) gained 5.7% after the ride-hailing platform

said it would bring autonomous ride hailing to Austin, Texas,

and Atlanta, in partnership with Alphabet's Waymo.

Advancing issues outnumbered decliners for a 6.86-to-1 ratio

on the NYSE and a 3.44-to-1 ratio on the Nasdaq.

The S&P 500 posted 45 new 52-week highs and no new low,

while the Nasdaq Composite recorded 66 new highs and 27 new

lows.
