    S&P 500 Shiller CAPE Ratio Hits 41, Flashing Rare Valuation Warning

    Question

    S&P 500 Shiller CAPE Ratio Hits 41, Flashing Rare Valuation Warning

    Direct answer

    The Shiller CAPE ratio, a cyclically adjusted price-to-earnings measure, has reached 41. This is a level only previously breached during the 2000 dot-com peak. While AI growth provides a fundamental narrative, the technical valuation suggests the market is highly vulnerable to any shift in sentiment or macro headwinds.
