Berkshire underperformance signals momentum unwind

The historic underperformance of Berkshire Hathaway relative to S&P momentum highlights an extreme market concentration ripe for a value-driven unwind.

The argument

The hosts pointed out that Berkshire's underperformance relative to the S&P 500 reached levels not seen since the peak of the 2000 tech bubble. They argued this extreme spread reflects an unsustainable market preference for AI momentum over diversified conglomerates, setting up a potential catch-up trade for value.

The thesis, stress-tested
✓ What validates it
  • Berkshire outperforming the S&P 500 on down days for tech
  • A narrowing of the performance spread between momentum and low-volatility indices
▸ Risks discussed
  • AI-driven momentum could persist longer than historical precedents suggest
  • Berkshire's cash drag could limit upside in a continuing bull market
Hear it yourself
"And I think, Santoli was on TV today. He made this point of, like, the torque of these rotations Huge. Has never been stronger. Yeah. And I so part of me feels like some of the selling in the big momentum year to date winners, maybe is people getting ready to buy SpaceX in the aftermarket at the end of this week. Some but a lot of it has to be algorithmic. A lot of it has to be people who are up huge in these trades, up a 200%. Part of the risk management is if this thing has a negative 5% there, I want I want out of the position. And everyone running that same playbook at the same time, with software is what produces a moment like what you're describing."
