Well-known market strategist Ed Yardeni of Yardeni Research recently raised his S&P 500 price target for 2026 to 8,400. The current S&P 500 stands at approximately 7,756 as of August 17, meaning the new target implies an additional 8% increase. Yardeni suggests the market could reach this level through sustained earnings growth, a resolution to the Iran conflict leading to lower inflation and stable interest rates, and continued demonstration of returns from AI investments by hyperscalers.
