  • Key Takeaway: Value investing requires a flexible definition that moves beyond traditional accounting metrics to capture long-term compounders.
  • Summary: Solely focusing on metrics like P/E or P/B is insufficient because the best-performing stocks rarely look cheap based on accounting figures. Miller IV emphasizes a ‘probabilistic fundamental value’ approach, balancing quantitative analysis with qualitative judgments on management alignment. Insider buying is considered a high-signal source of information when contextualized correctly.
Bitcoin as Undervalued Technology

(00:18:51)
  • Key Takeaway: Bitcoin is viewed as a superior, energy-backed capital governance technology whose value is derived from its separation from state-controlled fiat systems.
  • Summary: Miller IV argues Bitcoin is a massively undervalued technology because it functions as a capital denominator superior to gold due to its decentralized ledger secured by energy input, not state violence. The slow adoption mirrors historical technological shifts, like running water taking 100 years to become ubiquitous. He remains optimistic about its long-term trajectory despite volatility.
Market Environment and Sector Views

  • Key Takeaway: Current market extremes between large growth and SMID value resemble 1999, suggesting a potential multi-year period favoring capital-intensive, cyclically oriented value names.
  • Summary: The current narrow market leadership driven by AI narrative contrasts with an accelerating U.S. economy where capital now has a cost again (e.g., 6% mortgages). This dynamic creates compelling valuations in small/mid-cap value, which historically performed well following the dot-com bubble. Miller IV is overweight energy due to its high free cash flow contribution relative to its low market weight, and also favors financials and utilities.
