The S&P 500 (Index: SPX) reached a new record high close of 7,798.99 on Thursday, 13 August 2026 before falling back on Friday to end the trading week at 7,785.76.

Two developments helped to spur the index to its new heights. First, investors received good inflation news on Wednesday, 12 August 2026 when the Consumer Price Index came in lower than expected. The second came on Thursday, when the Producer Price Index was likewise reported to be lower than expected.

Because of these benign consumer and producer price inflation reports, the CME Group's FedWatch Tool no longer anticipates the Fed will act to hike the Federal Funds Rate from its current target range of 3.50-3.75% in September 2026, but will instead delay a quarter point rate hike to take place sometime in the fourth quarter of 2026. In its latest snapshot, the FedWatch Tool sees a falling 53% chance the Fed will act to hike this core interest rate to a target range of 3.75-4.00% on 28 October (2026-Q4) but gives a more solid 93% chance this rate will be in effect on 9 December (2026-Q4).

With the next rate hike likely delayed and fewer rate hikes on the table as a result of the better than expected inflation reports, the resulting lower interest rates kept investors focused on the first quarter of 2027 as they set current day stock prices. The latest update of the alternative futures chart shows the level of stock prices is right where they dividend futures-based model forecasts it would be provided investors are focused on 2027-Q1.

While those were the biggest headlines, other things happened that contributed to the random onset of new information investors absorbed and reacted to during the week that was. Here is our summary of the week's market moving headlines:
