Excess Returns
We Asked Chris Bloomstran Why He Won’t Own the S&P 500 At These Levels — And What He Does Instead
Most Important Insight
The S&P 500 is currently a highly concentrated momentum play where the top 10 stocks trade at a 35x multiple, creating a structural 'valuation trap' for passive investors over the next decade.
Most Original Insight
Corporate profit margins are artificially inflated by 'interest rate lag,' where companies are still benefiting from long-term debt issued at 2-3% while earning 5% on their cash, a tailwind that will reverse as debt matures.
Key Points
- The S&P 500 concentration has reached a historic extreme, with the top 10 companies representing over 30% of the index's total market capitalization.
- Current market valuations are predicated on profit margins remaining at all-time highs, ignoring the cyclicality of labor costs and the end of the low-interest-rate era.
- The 'passive bid' has decoupled stock prices from fundamental value, as index funds are forced to buy the most expensive stocks regardless of their underlying earnings power.
- Berkshire Hathaway serves as a superior alternative to the S&P 500 due to its $180 billion cash pile and diversified earnings from non-tech sectors.
- The 'Magnificent 7' are priced for a level of AI-driven growth that is mathematically improbable given the law of large numbers and increasing regulatory scrutiny.
- Active management is entering a 'golden age' as the valuation spread between the overvalued index leaders and the neglected 'old economy' stocks widens to 2000-era levels.
- Investors should expect nominal S&P 500 returns of 0-2% over the next 7-10 years when starting from current Shiller PE levels.
Investment Implications
| Asset / Sector / Instrument | Action | Source | Notes |
|---|---|---|---|
| Berkshire Hathaway (BRK.B) | BUY | explicit | He views it as a 'fortress' with better risk-adjusted return potential than the broader market due to its massive cash reserves and disciplined capital allocation. |
| Energy Sector | BUY | implicit | Bloomstran highlights the sector's low valuations and strong free cash flow yields as a hedge against broader market stagnation. |
| US Treasury Bills | HOLD | implicit | The emphasis on Berkshire's cash position implies that earning 5% on risk-free cash is currently superior to chasing overvalued equities. |
| S&P 500 (SPY) | SELL | explicit | Bloomstran warns that the index is priced for a 'lost decade' due to extreme concentration and 24x forward earnings multiples. |
| Mega-cap Tech (Magnificent 7) | SELL | implicit | The argument suggests these names are the primary drivers of the index's overvaluation and are vulnerable to margin compression. |
Hang on a sec…
- Bloomstran claims that profit margins must mean-revert to historical averages, but this ignores the structural shift toward high-margin software and capital-light business models that didn't exist in previous decades.
- The assertion that passive investing is a 'bubble' is questionable; passive flows reflect market sentiment rather than creating it, and the mechanism has survived multiple cycles without 'popping' as described.
- He heavily promotes Berkshire Hathaway as the primary solution, but the firm's massive size now acts as a 'gravity' that makes significantly outperforming the S&P 500 much harder than in the past.
