The widely watched market valuation indicator, the Shiller CAPE ratio (Cyclically Adjusted Price-to-Earnings ratio), recently surpassed 41. This has only occurred twice in 145 years of data, with the other instance being at the peak of the dot-com bubble in late 1999. Additionally, the "Buffett Indicator," which measures the total stock market capitalization to GDP, reached an all-time high of over 240% as of August 18th.
