The Price-to-Book (P/B) ratio compares a company’s market value with its book value. Mathematically, the P/B ratio can be calculated as follows:

  • P/B Ratio = Market Price Per ShareBook Value Per Share

For example, suppose a company’s share price is ₹300, and its book value per share is ₹150. Now, P/B = 2 (₹300 divided by ₹150), which indicates that the market price is two times the company’s book value per share.

How to Analyse the P/B Ratio in Indian Stocks?

Generally, investors examine the various levels of the Price-to-Book (P/B) while performing a fundamental analysis. Let’s check them out:

P/B RatioWhat It May Indicate
Low P/BThe stock’s market price is relatively low compared with its book value. This may indicate a lower market valuation.However, such a situation can also point towards:
Weak profitabilityPoor asset qualityBusiness risks, or Low expected returns.
High P/BThe market price is relatively high compared with book value. This may potentially indicate:
A higher expected profitabilityStronger returns on equityCompetitive advantages, or Expectations of future growth.
P/B with High ROEA higher P/B may be supported when the company consistently generates strong returns on its equity.
P/B with Low ROEA low P/B may not represent an attractive valuation if the company generates weak returns from its equity base.

For example, Company A may trade at a P/B of 1.2 but have weak ROE and declining profits, while Company B may trade at a P/B of 4 but have consistently higher ROE and stronger profitability. 

The lower P/B of Company A does not automatically make it “cheaper” in valuation terms.

Therefore, P/B is generally assessed alongside ROE, earnings, asset quality, debt, and industry averages. Additionally, the appropriate P/B level also differs across industries.
