INSIGHT

Maps Versus The Business

Financial statements are maps, not the business itself, and can obscure real drivers like culture, customers, and pricing power.
Valuation debates are often hidden disagreements about time horizon and assumptions, not absolute truths.

ADVICE

Question Why Concentration Exists

Ask which assumptions must remain true for market concentration to be justified rather than using concentration as a timing signal.
Evaluate each dominant firm's ability to sustain growth, margins, and capital discipline before drawing conclusions.

INSIGHT

Whether a stock is 8% or 1% of an index shouldn't change your valuation process.
