Stock Market Signals Warning Amid Declining Consumer Sentiment
The U.S. stock market is showing signs of concern as consumer sentiment reaches its second-lowest level on record, driven by persistent inflation and economic uncertainty linked to President Trump's policies. The University of Michigan’s Index of Consumer Sentiment dropped to 46.3 in October 2026, with consumers expecting annual inflation to reach 4.7%. This decline is particularly worrying because consumer spending accounts for two-thirds of GDP, making it a key driver of economic growth and corporate earnings. Historically, falling consumer sentiment has often preceded stock market declines. For example, the S&P 500 dropped nearly 57% during the Great Recession after peaking in early 2007 when consumer confidence was high. A similar pattern occurred between April 2021 and June 2022, with a 25% drop following declining sentiment. The current situation is compounded by an elevated S&P 500 cyclically-adjusted price-to-earnings (CAPE) ratio of 40.6 — the highest since the dot-com bubble in 2000 and among the most expensive valuations historically. The high CAPE ratio suggests that stocks may be overvalued, increasing the risk of a correction if economic growth slows or corporate earnings disappoint.
