"Stock Market Outlook: Comparing Today's Valuations to the 1990s Dot-Com Bubble"

DataTrek Research suggests that historical trends indicate the S&P 500 is not in bubble territory, as the index has gained 31% over the last three years, near its long-term average, and stock market crashes often occur when three-year gains reach 100% or more. This contrasts with concerns of a market bubble fueled by exuberance, particularly in artificial intelligence investments. However, not all experts agree, with some warning of overvaluation and the potential for weak future returns.
