How to Analyze Industries Like a Value Investor

Industry Structure Analysis

  • Competition level: Fragmented industries with many players vs. consolidated oligopolies
  • Barriers to entry: How easily can new competitors enter? High barriers = better moats
  • Pricing power: Can companies raise prices, or are they price-takers?
  • Customer concentration: Many small customers or a few large ones?

Economic & Cyclical Factors

  • Cyclicality: Does the industry boom and bust with the economy?
  • Growth trajectory: Mature, growing, or declining industry?
  • Regulatory risk: Heavy government oversight or regulatory changes ahead?
  • Technology disruption: Is the business model at risk from innovation?

Pro Tip: Industry Leaders vs. Challengers

In mature industries, established leaders often have stronger moats and pricing power. In growing industries, agile challengers may offer better growth. Consider where the industry is in its lifecycle, and evaluate what gives each company a margin of safety.
