Understanding companies
Price-to-book compares the market value of equity with its accounting book value. It shows the premium or discount applied to the recognised net assets, not whether that pricing is justified.

Place a buyer's price for a workshop beside the net value written in its ledger. The gap may reflect earning power, hidden value, weak assets, risk or simple mispricing.
Now put that into markets
The ratio divides share price by book value per share or market capitalisation by matching equity. Both parts need compatible dates and ownership definitions.
Businesses expected to earn strong returns on equity often trade above book; impaired or low-return assets can justify a discount. Accounting treatment influences the denominator.
Use P/B with asset quality, return on equity and capital requirements. Compare companies under similar accounting and regulatory structures.
A ratio below one does not prove bargain value, and a high ratio does not prove excess. Book value can omit important intangibles or overstate assets that need impairing.
