Yardeni Says He Hasn't Been Bullish Enough on Earnings

Ed Yardeni, president of Yardeni Research, believes he underestimated the impact of earnings on market performance and has raised his S&P 500 year-end forecast from 8,250 to 8,400. He attributes the market's upward momentum primarily to strong earnings growth and remains bullish on the artificial intelligence trade as a significant market driver.
