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 

Strong corporate profit margins may make the S&P 500 better value than traditional P/E ratios suggest, despite elevated stock prices. Per Bloomberg, its P/E-to-profitability ratio is at its lowest in nearly 14 years, last seen around 2012. Wall Street might be overlooking something important. 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 

US large-cap equities do not look like a bubble at current forward valuations. The S&P 500 forward P/E is below both its five- and ten-year averages, while tech and momentum have suffered their worst five-month decline by far. x.com 

The S&P 500's relatively low valuation supports a pre-midterm TACO rebound. It trades at 18.5 times forward earnings, below its five-year average of 19.9 and ten-year average of 19.2, the cheapest since the April 2025 tariff low. x.com 

The S&P 500 rally is a concentration bet because earnings growth is coming from very few companies, while AI productivity gains are not spreading across the broader economy. 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 

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. Positive breadth divergences, record short ETF exposure and put volume, and semiconductors waking up add to the case. In all 19 post-midterm instances cited, markets were very green over the following 12 months. x.com  x.com 

Amazon looks cheap against its expected long-term earnings growth if that growth proves accurate. Its five-year consensus growth is the fastest in the Magnificent 7 after Nvidia, while its 0.90 forward P/E-to-growth ratio is the lowest excluding Nvidia. x.com  x.com 

US stocks need not rise just because profits are strong: that is first-level thinking, and everyone already knows earnings are growing. P/E multiples fell over the past six months despite upward EPS revisions, and years like 2018, 2006, 2005 and 2004 saw EPS growth near 17-20% with weak or negative index returns. Valuations sit in the 98th percentile, inflation, rates and deficits are rising, policy may turn anti-corporate after November, and AI capex has inflated profits. x.com 

The S&P 500 has convexity if earnings keep growing while the 10-year yield eventually falls from 5.3% back toward 4-4.5%. The index is near record highs yet getting cheaper relative to expected growth, because earnings are rising faster than prices. Treasury yields above 5% have compressed the multiples investors pay for future growth, while the AI capex cycle expands the earnings base; those two enormous forces are pushing against each other. x.com
