Extended read
The Shiller CAPE ratio, which adjusts for inflation and cyclically smoothed earnings, has crossed the 41 threshold. This is a rare technical signal of overvaluation, historically associated with the 2000 market peak. While AI-driven growth in mega-cap tech like NVDA and MSFT supports the current rally, the broader index is increasingly vulnerable to multiple contraction. The Invesco Nasdaq 100 ETF (QQQM) currently carries an even higher P/E of 25.1, reflecting the concentration of AI and semiconductor leaders. Investors are increasingly looking at value alternatives like VTV, which has only 13% tech exposure, as a defensive play against a potential valuation correction.
