Ed Yardeni, President of Yardeni Research, predicts the S&P 500 could reach 10,000 points by the end of the decade, driven by strong corporate earnings growth. In a recent interview, Yardeni emphasized that the current market rally is not speculative but supported by earnings, with the S&P 500's forward P/E ratio of 20 to 22 being justifiable if the U.S. avoids a recession. Despite acknowledging some "melt-up" characteristics in semiconductor stocks, Yardeni remains optimistic about the long-term market outlook, suggesting a potential 33% upside from current levels under a "Roaring Twenties" scenario.
