The last time the S&P 500 rose this rapidly The S&P 500’s rapid rise in April and May, up over 16%, is a magnitude of gain not seen outside of major economic shocks or recovery periods since World War II. While excitement around artificial intelligence has fueled tech stocks, analysts are concerned the speed of the rally, outside of a recession, mirrors the period before the 1987 crash. Lingering risks such as potential Federal Reserve rate hikes, tight corporate credit spreads, and geopolitical factors like the Strait of Hormuz create a concerning backdrop for the current market euphoria.
