S&P 500 earnings are keeping pace with prices, so this does not look like a bubble. Quarterly earnings are on track to grow 29.5%, more than twice the 10-year average of 12.6%, while the 18.7 forward P/E is just below its 19.1 decade average. x.com 

S&P 500 stocks look cheap relative to expected earnings as forecasts grow faster than share prices. Forward P/E has fallen below 19, its lowest since 2023 and slightly below its 10-year average, despite the index nearing all-time highs. Goldman Sachs' earnings beat, with net income up 29% year over year, suggests earnings support extends beyond AI. x.com 

The S&P 500's elevated P/E masks concentration in just a few stocks, making index exposure less appealing than selective stock picking for risk and reward. Its P/E is well above the ten-year median; digging into individual constituents looks more sensible than buying all 500. x.com

Rising S&P earnings revisions and a Nasdaq valuation far below the 2000 bubble level argue against a bull trap in US large caps. Nasdaq trades at 18x forward earnings versus over 80x in 2000.

Nvidia and Micron drive 34% of expected Q3 earnings growth, and ten companies account for two-thirds. Apollo's revenue-per-worker chart shows gains for the Magnificent Seven but little for the other 493 S&P 500 companies; most stocks that reflect the broader economy are down. x.com  x.com  x.com
