P/B — Price-to-Book Ratio

DeepScreen explains P/B as follows: P/B compares market value with accounting net assets. It is most useful for banks and asset-heavy companies and less useful for software or brands whose assets are not fully recorded.

Formula

Share price ÷ book value per share

Illustrative example

A share price of 60 divided by book value per share of 30 gives P/B of 2x. Check whether the recorded assets need impairment.

Educational example; these are not reported company figures.

How to interpret it

  • Below 1 means the market values equity below stated book value.
  • A premium can be justified by high, durable returns on equity.

Limitations

  • Book values can contain impaired or low-quality assets.
  • Cross-sector comparisons are misleading.
