JPMorgan Chase believes that individual investors may continue to support the U.S. stock market until the end of the year, but Goldman Sachs believes that any correction will not be long-lasting.

JPMorgan Chase strategists said that strong inflows of retail funds are expected to support the U.S. stock market until the end of the year. The team led by Nikolaos Panigirtzoglou pointed out in a report that this forecast is based on seasonal patterns of fund flows in stock funds over the past ten years. They found that in non-presidential election years, the average inflow of funds is usually higher in December and the following first quarter. The S&P 500 index just recorded six consecutive months of gains, marking its longest winning streak since August 2021, with cumulative gains of nearly 6% in September and October. As the artificial intelligence boom drives the stock prices of tech giants higher, the benchmark index has already hit 36 new all-time highs this year. Panigirtzoglou and his team noted, "From a seasonal perspective, the strong momentum of retail funds flowing into the stock market over the past two months is likely to continue into early 2026."
