Outlook for the future: How will the U.S. stock market perform in the second half of 2025?
CITIC Research believes that the shift in fiscal policy and the easing of tariffs are continuously enhancing the medium-term visibility of the U.S. economy, combined with the operating cycle of the Technology sector, which is still in an upward phase, as well as the current low holdings of domestic investment institutions in U.S. tech stocks, looking at the performance of U.S. tech stocks in the next 6 to 12 months.
Morgan Stanley's Chief Investment Officer Mike Wilson expects that the performance of the U.S. stock market in the second half of this year will be more stable than in the first half. The firm has set a year-end target price of 6500 points for the S&P 500 Index, approximately 5% higher than the current level. It believes that the reduction in tariff rates has significantly lowered the risk of recession, the market bottomed during the "Liberation Day sell-off," and more and more companies are raising their profit forecasts, which is a major sign of market optimism.
Hussein Malik, Global Research Head at JPMorgan, expects the U.S. economy to slow down in the second half of the year; however, with the deepest concerns related to the trade war dissipating, a recession is unlikely. As inflation remains high, interest rates will stay elevated for a longer period, with expectations that the Federal Reserve will cut rates by 100 basis points between December and Spring 2026, bringing the final rate down to 3.5%. The firm’s year-end target price for the S&P 500 Index is set at 6000 points.
Wells Fargo & Co's Chief Investment Officer Darrell Cronk believes that multiple bullish factors may drive U.S. stocks to achieve new highs before the end of the year. The market should not be overly concerned about the economic outlook, as inflation is moving toward normalization, and the easing of regulatory policies will benefit businesses, particularly small and medium enterprises. The firm predicts that the S&P 500 Index will end the year between 5900 and 6100 points.
