The Price-to-Book (P/B) ratio is a simple number that shows how much investors pay for each rupee of a company’s net asset value (book value). It is calculated by dividing the current market price of a stock by its book value per share. The P/B ratio helps you understand if a stock is cheap or expensive based on the company’s assets, like land, buildings, and cash, after deducting liabilities. A low P/B ratio might mean the stock is undervalued or the company has problems, while a high P/B ratio could mean investors expect good future growth. Using the P/B ratio helps Indian investors find stocks that may be trading below their true worth.
What is the Price-to-Book (P/B) Ratio?
The P/B ratio shows the price investors pay for the company’s net assets. It is found by dividing the stock’s market price by its book value per share.
P/B Ratio = Market Price per Share ÷ Book Value per Share
Book value is the company’s total assets minus its liabilities. For example, if a stock price is ₹200 and book value per share is ₹100, the P/B ratio is 2. This means investors pay ₹2 for every ₹1 of the company’s net assets.
How to Calculate the P/B Ratio for Indian Stocks?
To calculate the P/B ratio, divide the current market price of a stock by its book value per share.
Book value per share = (Total Assets – Total Liabilities) ÷ Number of Shares.
For example, if a company has assets worth ₹1000 crore and liabilities of ₹400 crore, and there are 30 crore shares, then:
Book value per share = (1000 - 400) ÷ 30 = ₹20.
If the current stock price is ₹40, then P/B ratio = 40 ÷ 20 = 2.
This means the stock trades at twice its book value.
Why is the P/B Ratio Important for Indian Investors?
The P/B ratio helps Indian investors understand if a stock is priced fairly compared to its net assets. Stocks with a P/B ratio below 1 may be undervalued, meaning the market price is less than the company’s asset value. This can be a good buying opportunity if the company is healthy. On the other hand, a high P/B ratio might mean the stock is expensive or investors expect high growth. It is important to compare P/B ratios within the same industry because asset types and values differ.
Limitations of the P/B Ratio in the Indian Market
Although useful, the P/B ratio has some limits.
It is less helpful for companies with lots of intangible assets like brands or software, common in Indian IT firms.
Sometimes assets on the balance sheet may be outdated or undervalued.
Also, the ratio doesn’t consider future earnings or cash flows.
So, always use P/B along with other financial ratios and research before investing.
Where Can Indian Investors Find P/B Ratios?
You can find P/B ratios for Indian stocks on popular financial websites like Moneycontrol, NSE India, and BSE India.
Many trading platforms and brokerage apps also show P/B ratios along with other stock details.
Company annual reports and quarterly filings include asset and liability information needed to calculate the P/B ratio.
Watching the P/B ratio regularly helps you spot stocks that may be undervalued or overvalued.
