    Question

    S&P 500 Shiller CAPE Ratio Nears 41 Amid Four-Year 21% Annualized Run

    Direct answer

    Long-term valuation metrics for US equities show the S&P 500 CAPE ratio touching 41. Historical precedents for this valuation tier remain limited to the 1929 market peak and the 1999 technology bubble peak. The expansion follows a four-year period of 21% annualized index appreciation. The extreme reading leaves broad equities highly sensitive to any shift in corporate earnings trajectory or rate cut pricing. — bullish pressure on GLD.
