[JPMorgan Analyzes FOMC Decision Impact on U.S. Stocks: 50% Chance Fed Remains Hawkish, S&P 500 May Weaken] BlockBeats News, July 29: JPMorgan conducted an analysis of the potential impact of tonight's FOMC decision on U.S. stocks. JPMorgan predicts that the Federal Reserve will keep interest rates unchanged, with a hawkish stance as the baseline scenario (50% probability), under which the S&P 500 index would remain roughly flat or decline by 0.5%. A dovish stance scenario (28% probability) is viewed as the most bullish outcome, potentially pushing the index up by 1%. In the scenario of a 25 basis point rate hike (20% probability), the S&P 500 index could drop by 1.5%-2%, with the Nasdaq index likely to underperform.
