Prominent strategist Yardeni suspects U.S. stocks are approaching the edge of a correction, uncertainty exists about year-end gains.

Investors' belief in the "only rise, no fall" trend in the US stock market seems unbreakable, causing even one of Wall Street's most steadfast bulls to start feeling uneasy. He believes that this excessive optimism is sending out a typical "contrarian warning signal". Ed Yardeni, the founder of Yardeni Research and a long-term bull, stated that "there are too many bulls." Over the past six months, the stock market has almost completely ignored all warnings, maintaining a sharp upward trend. Although the Federal Reserve chairman has remained cautious about the possibility of a rate cut in December, investors' enthusiasm has been largely unaffected. Yardeni has begun to question his prediction of a year-end market rally. Data shows that since early April, the S&P 500 index has surged by 37%, a magnitude that has only been exceeded five times since 1950. As we enter November, historical data shows that this is historically the best-performing month for the stock market in the past 30 years. Yardeni currently predicts that the S&P 500 index may drop by up to 5% from its peak by the end of December, as both sentiment and technical indicators indicate that the market heat has gone too far.
