S&P 500 Sees Small Decline in Week Without Major Market Moving News

After closing out the preceding week at a record high, the S&P 500 (Index: SPX) clocked a new record high close of 6,977.27 on Monday, 12 January 2026 before retreating a half percent to end the week at 6,940.01, about 0.4% below its previous week's close.

There really wasn't any single catalyst to prompt the retreat. Instead, the general flow of news during the week was mildly negative for the outlook of large publicly traded firms, with the result being that stock prices ended the week marginally lower.

For example, inflation news during the week that was did little to influence expectations for how U.S. interest rates will change during 2026. The CME Group's FedWatch Tool continues to project the Fed will hold the Federal Funds Rate steady until 17 June (2026-Q2), when it anticipates a quarter point rate cut. The tool forecasts another quarter point reduction on 28 October (2026-Q4), six weeks later than it forecast a week earlier.

Perhaps the biggest surprise during the week was President Trump putting potential new tariffs on the table on Friday, 16 January 2026 for European nations opposing U.S. negotiations to acquire the territory of Greenland from Denmark. Which considering how President Trump has transformed tariffs into a tool for the U.S.' international diplomacy over the last year isn't a terribly surprising development and did little to affect stock prices.

All in the all, we find the trajectory of the S&P 500 is right about in the middle of the redzone forecast range shown on the latest update of the alternative futures chart for 2026-Q1.
