The S&P 500 Is at Record Highs and Hasn't Been This Expensive in Decades. History Says This Could Happen Next

The S&P 500 has reached record highs at 7,800 but is trading at a Shiller PE ratio of 42, the highest since the dotcom crash. Similar to the early 2000s bubble driven by internet stocks, today's rally is fueled by AI companies. However, history shows that even profitable tech giants like Microsoft, Apple, and Cisco crashed over 50% during the dotcom bubble. Investors are advised to shift from expensive stocks to more reasonably priced investments and dividend stocks rather than trying to time the market.
