    Question

    S&P 500 Shiller CAPE Ratio Surpasses 41, Signaling Significant Overvaluation

    Direct answer

    The Shiller CAPE ratio's move above 41 places the current market in the top 1% of historical valuations. This level was last reached in 2000, immediately preceding the dot-com crash. While AI infrastructure spending remains robust, the valuation ceiling is being tested as macro risks mount.
