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 

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 

US equities are in a remarkably strong earnings environment, with S&P 500 sales and earnings revisions for 2027 surging. Markups on equity investments don't explain it, since sales wouldn't reflect them and these are 2027 estimates. Breadth is also fairly strong, so stripping out the mega caps, as @EcoDogFanJM suggests, isn't warranted. x.com  x.com 

US stocks face a potentially bigger selloff as rising inflation compounds concerns about AI spending. PCE inflation reached a four-month high of 3.6%, increasing pressure on the Fed to raise rates; Alphabet shares fell after disappointing earnings, slowing ad growth and more than $51 billion of quarterly capital investment. x.com 

Broader participation, earnings growth and lower multiples support US equities into year-end, with seasonality also favorable. The equal-weight S&P rose 1.95% this week while the cap-weighted index slipped 0.05%; EPS is up 38% so far and multiples are down 17% year to date. The 10-year yield fell 41 basis points. 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 

US large-cap stocks are frothy and now need years of earnings to validate today's prices, even though the rally is not irrational. Per FactSet, S&P 500 earnings are up about 28% versus 13% expected, but the Shiller P/E is near 42, close to 1999-2001 extremes. Per @KobeissiLetter, leveraged ETF assets hit a record $177B and the leading-to-coincident indicator ratio of 0.84 matches the 2008 low; per @charliebilello, 90+ day delinquencies hit 13.1% for credit cards and 5.6% for auto loans. x.com  … Show more

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
