Simply Wall St

As of late September 2025, U.S. stock markets have experienced a downturn with major indices like the Dow Jones Industrial Average and the S&P 500 closing lower for two consecutive sessions, primarily due to declines in technology stocks despite an outperforming energy sector. Amidst these fluctuations and concerns over high valuations as noted by Federal Reserve Chair Jerome Powell, identifying undervalued stocks becomes crucial for investors seeking opportunities that may offer growth potential without the premium price tags associated with some sectors.
