P/B Ratio

The Price-to-Book (P/B) Ratio compares a company's current market price to its book value — the net asset value recorded on its balance sheet. A P/B below 1.0 may suggest the stock trades below the value of its tangible assets, while a high P/B implies the market expects strong future earnings growth.

To calculate P/B, divide the current share price by the book value per share. Book value equals total assets minus total liabilities, divided by the number of outstanding shares. For example, if HDFC Bank trades at INR 1,600 and its book value per share is INR 450, the P/B ratio is approximately 3.6.

In Indian markets, P/B is particularly important for banking and financial stocks listed on the NSE and BSE. Banks with strong asset quality and consistent return on equity typically command higher P/B multiples. Conversely, PSU banks with stressed asset books often trade at P/B ratios close to or below 1.0.

The ratio has limitations — it works best for asset-heavy sectors like banking, real estate, and manufacturing. For IT companies like Infosys or TCS, where value lies in intellectual capital and human resources rather than physical assets, P/B is less meaningful. Investors should combine P/B analysis with P/E Ratio, Return on Equity, and debt metrics for a complete valuation picture.

A low P/B alone does not make a stock a bargain. Companies with deteriorating fundamentals, governance issues, or structural decline may trade at low P/B ratios for valid reasons — this is often called a "value trap." Always investigate why the market has assigned a particular valuation before acting on P/B signals.
