04:35 PM EDT, 08/15/2025 (MT Newswires) -- The Standard & Poor's 500 index rose 0.9% this week, scaling new peaks in four consecutive trading sessions, as the probability of an interest-rate cut in September remained elevated following divergent inflation reports.

The S&P 500 ended Friday's session at 6,449.80, bringing quarter-to-date gains to 4%, and year-to-date growth to 9.7%.

Following a weaker-than-expected non-farm payrolls report last Friday and a surprise drop in the Institute for Supply Management's US services index, the US seasonally adjusted consumer price index rose 0.2% in July, as expected in a survey compiled by Bloomberg, and below the 0.3% gain in June, according to the Bureau of Labor Statistics on Tuesday.

The odds of a 25-basis-point cut in September reached 99.9% after the soft consumer price data, according to the CME Fedwatch Tool. This near-certain probability, however, dissipated to 92% on Thursday after BLS data showed the Producer Price Index rose 0.9% in July, from no growth in June, and compared with the 0.2% increase forecast in a survey compiled by Bloomberg.

The rate-cut probability settled at 89% late on Friday after the University of Michigan's preliminary consumer sentiment index fell to 58.6 in August from 61.7 in July, below expectations for an increase to 62 in a Bloomberg-compiled survey. Respondents' one-year inflation forecasts at 4.9% were up from 4.5% in July, while five-year inflation outlook climbed to 3.9% from 3.4%.

Healthcare, communication services, and consumer discretionary were the top three gainers this week.
