The S&P 500's cyclically adjusted price-to-earnings ratio has climbed to roughly 41.4, approaching the all-time high reached during the dot-com era and marking a level seen only once in the last 150 years. The CAPE ratio, which divides the index price by average inflation-adjusted earnings over the past decade, has historically averaged between 16 and 17, and steep short-term rises have preceded market declines, including the Great Depression and the tech bubble. Investors are advised to focus on companies with strong balance sheets, predictable earnings, and diversified portfolios to weather a potential correction.
