How to read this chart

Most useful for asset-heavy businesses: banks, insurers, REITs. A P/B near its historical low suggests the market is paying unusually little for the net assets.

Key caveats
  • Goodwill and intangibles from acquisitions can inflate book value significantly — some analysts prefer tangible book value.
  • Low P/B in technology or software companies is usually irrelevant: their value is in IP and people, not balance sheet assets.
