What Does the P/B Ratio Mean?

The P/B ratio compares a company’s market price to its book value per share.

P/B Ratio Interpretation:

  • P/B < 1.0: Potentially undervalued (trading below book value)
  • P/B = 1.0: Market price equals book value
  • P/B > 1.0: Market premium over book value
  • P/B > 3.0: Possibly overvalued (common in high-growth stocks)

Industry Benchmarks:

  • Banks/Financials: 0.5 – 1.5
  • Manufacturing: 1.0 – 2.5
  • Tech/Growth Stocks: 3.0 – 10.0+

Why the Price-to-Book Ratio Matters

The P/B ratio is a key financial metric used by value investors to assess whether a stock is trading at a fair valuation relative to its net asset value. A low P/B ratio may indicate an undervalued stock, while a high P/B ratio could suggest overvaluation or high growth expectations.

Limitations of the P/B Ratio

  • Less useful for service-based or asset-light companies
  • Does not account for intangible assets (brand value, patents)
  • Book value may not reflect true market value of assets
