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 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 

Improving breadth and GPUs massively outrunning depreciation costs put US-equity risk/reward heavily in bulls' favour. Some 59% of S&P 500 stocks are above their 50-day average; the Nasdaq 100 is positive over five trading days, and small caps bounced off their 200-day average. Buy gradually, as the selloff may not be completely over. 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 

Rising inflation, costlier AI infrastructure financing and growing Iran escalation risk point to the final major S&P 500 correction before the biggest phase of the AI boom. The index is near its 125-day average; its last break below in March was followed by another 10% drop. Keep cash ready: the next sell-off will create generational buying opportunities as neoclouds and hyperscalers turn infrastructure spending into explosive revenue and earnings growth. 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 

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 

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 

US large-cap stocks keep rising because AI is extremely powerful, and earnings are growing faster than prices, compressing valuations despite record value creation. Per FactSet's John Butters, blended S&P 500 Q2 earnings grew about 29% year over year even excluding Alphabet and Amazon, while the index rose only about 21% over the same period. x.com
