We Asked Chris Bloomstran Why He Won’t Own the S&P 500 At These Levels — And What He Does Instead

I joined Justin Carbonneau for one more special episode of Excess Returns.

We spoke with Chris Bloomstran soon after his famous annual letter release, and right before the Berkshire meeting in Omaha.

This episode features Chris Bloomstran of Semper Augustus discussing market concentration, AI capital spending, Berkshire Hathaway, and the risks facing today’s equity investors. The conversation explores whether we are at a secular valuation plateau, how AI investment may reshape returns, and why passive investors may face more risk than they realize.
