Investor sentiment in the U.S. stock market is showing signs of extreme optimism, with the Conference Board's survey indicating the highest confidence in market growth over the next year. However, this bullish sentiment is contrasted by the American Association of Individual Investors (AAII) Sentiment Survey, which shows the highest percentage of bearish responses in a year. The Euphoriameter, an indicator by Topdown Charts, has hit a record high of 1.1 points, signaling potential caution due to high valuations and a 'you only live once' (YOLO) attitude towards riskiest assets. Despite new record highs in the market, more individual stocks are entering downtrends, and there is widespread complacency among investors. This dichotomy in market sentiment, coupled with December traditionally being an exuberant month for stock markets, suggests that contrarian signals might be indicating a market correction could be on the horizon in the first half of 2025.
