Aug 30 (Reuters) - Wall Street's main indexes rose on Friday and were set for monthly gains after a key inflation report reiterated moderating price pressures, cementing bets for an interest-rate cut at the U.S. Federal Reserve's upcoming meeting in September.
The Personal Consumption Expenditure index , the central bank's preferred inflation gauge, rose 2.5% in July on an annual basis compared to an estimate of 2.6%, according to economists polled by Reuters. On a monthly basis, it rose 0.2% as expected.
Among rate-sensitive megacaps, Amazon.com AMZN.O and Microsoft MSFT.O gained 1.3% and 0.7%, respectively. Chip stocks rose; Broadcom AVGO.O added 3.4% and Advanced Micro Devices AMD.O climbed 1.4%, aiding the Philadelphia SE Semiconductor index's .SOX 2.2% rise.
Friday's PCE report is the last before the Fed's September meeting and follows Chair Jerome Powell's comments last week expressing support for an imminent policy adjustment.
"Powell's speech at Jackson Hole reiterated several times that we're approaching our desired target. Nothing here is going to cause me to change anything," said Andre Bakhos, managing member at Ingenium Analytics.
"We still have the jobs report coming out Friday, which would even be a greater concern."
Odds of a 25-basis-point reduction stood at 69.5%, according to the CME Group's FedWatch Tool, while those of a 50-bps reduction were at 30.5%.
Global markets are the end of a tumultuous month for riskier assets, after signs of a sudden moderation in the labor market sparked fears of a quicker-than-expected slowdown in the world's largest economy in early August. The influence of the Japanese yen JPY= carry trade worsened the rout.

At 09:44 a.m. the Dow Jones Industrial Average .DJI rose 114.66 points, or 0.28%, to 41,449.71, the S&P 500 .SPX gained 36.45 points, or 0.65%, to 5,628.41 and the Nasdaq Composite .IXIC gained 156.25 points, or 0.89%, to 17,672.68.

The tech-focused Nasdaq .IXIC and the S&P 500 .SPX closed lower on Thursday after Nvidia NVDA.O failed to match sky-high investor expectations, despite upbeat results and a broadly in-line forecast. The AI-chip bellwether was up 1.7% after a 6.4% drop in the previous session.
The S&P 500 is close to an all-time high, poised for a monthly gain of 1.8%, while the Nasdaq is up 0.3% in August.
