The plain reply is that uncertainty brought on by President Donald Trump’s tariff coverage is responsible.

The S&P 500’s Shiller price-to-earnings (P/E) Ratio, which is often known as the cyclically adjusted P/E Ratio (CAPE Ratio), entered 2025 on the third-highest premium throughout a bull market when back-tested 154 years. It peaked at a a number of of 38.89 in December 2024, which compares to a median a number of of 17.23 since January 1871.

Trying again 154 years, there have only been a half-dozen occasions, together with the current, the place the S&P 500’s Shiller P/E surpassed 30 and held that degree for not less than two months. The previous 5 occurrences all resulted in a lack of worth of between 20% and 89% in a number of of Wall Avenue’s main inventory indexes shedding between 20% and 89%.
