The S&P 500 (Index: SPX) climbed 1.2% over its previous week's close to end the trading week at 7,743.41 on Friday, 25 September 2026. The index is just 0.7% below its record all-time high closing value from 13 August 2026.

The same things that have been rattling investors for much of the third quarter of 2026 continued trying to scare investors during the week that was. Oil prices kept jumping about with geopolitical developments. The big AI companies kept themselves in the news with releases of new flagship products and calls for regulation that seem aimed at helping them avoid product liability claims. Meanwhile, bond markets all over the globe have been coping with quickly rising yields, with stock prices reacting to their ups and downs.

Plus, it's not even October yet, which is historically the scariest month for stock prices because it's the most volatile!

Even with all the week's news and the upcoming scary season, the S&P 500 performed predictably. The latest update of the alternative futures chart shows the index' trajectory is pretty closely following the dividend futures-based model's projection of where stock prices are expected provided investors are focusing on the final quarter of 2026.

Here are the headlines that contributed to how the market moved during the trading week ending on the final full week of September 2026.
