Tom Lee, in an interview with CNBC, expressed optimism about the U.S. stock market's potential for further growth despite reaching record highs. According to ChainCatcher, Lee highlighted that the valuation of leading stocks, particularly those related to AI and semiconductors, remains reasonable. He noted that the forward price-to-earnings ratio for semiconductor and tech leaders is approximately 22 times, which is significantly lower than the historical peak over the past 20 years. Lee emphasized that the demand in these sectors continues to grow explosively, suggesting there is still room for upward movement. He projected that the S&P 500 could reach 7,700 or higher by the end of the year.
