What is PE Ratio?
PE ratio stands for Price-to-Earnings ratio. It tells you how much investors are willing to pay for every rupee of a company's earnings .
Formula: PE Ratio = Market Price per Share ÷ Earnings per Share (EPS)
If a stock trades at 100 and its EPS is 5, the PE ratio is 20. This means investors pay 20 for every 1 of earnings .
What PE Ratio Tells You
- A high PE ratio means investors expect strong future growth. They are willing to pay more today for profits that will come later. Tech companies often have high PE ratios for this reason .
- A low PE ratio means the stock may be undervalued. Or it could mean the market expects earnings to decline. You need to check why the PE is low before buying .

What is PB Ratio?
PB ratio stands for Price-to-Book ratio. It compares a company's market value to its book value. Book value is what would be left if the company sold all assets and paid all debts .
- Formula: PB Ratio = Market Price per Share ÷ Book Value per Share
- Book Value = Total Assets – Total Liabilities
If a stock trades at 150 and its book value per share is 100, the PB ratio is 1.5. This means investors pay 1.50 for every 1 of net assets .
What PB Ratio Tells You?
- A PB ratio below 1 means the market values the company at less than its net assets. This can signal undervaluation. But it can also mean the assets are not worth what the balance sheet shows .
- A high PB ratio means investors believe the company can generate strong returns from its assets. Tech companies often have high PB ratios because their value comes from intangible assets like software and brand, not physical assets .
PE Ratio vs PB Ratio: Key Differences
What They Measure
PE ratio measures how much you pay for earnings. PB ratio measures how much you pay for net assets .
When to Use PE Ratio?
- PE ratio works best for companies with stable earnings. It is useful for most sectors. But it can mislead for cyclical companies like steel or cement. At the peak of a cycle, earnings are high and PE looks low. But the cycle may be about to turn .
- PE ratio also fails for companies with negative earnings. You cannot calculate a meaningful PE when EPS is negative .
When to Use PB Ratio?
- PB ratio works best for asset-heavy businesses. Banks, insurance companies, and manufacturers have large tangible assets. For these sectors, PB ratio is more reliable than PE .
- Bank profits can be distorted by loan loss provisions. Net worth (book value) is more stable. This is why analysts use PB ratio for banks .
- PB ratio does not work well for tech companies. Their value comes from intellectual property, research, and brand. These assets do not appear fully on the balance sheet .
PE Ratio vs PB Ratio Chart: How to Compare Stocks
You can use charts to compare these ratios across companies. Here is how to read them .
- PE Ratio Chart: Shows how expensive a stock is relative to its earnings over time. If today's PE is at a 5-year low, the stock may be cheap compared to its own history.
- PB Ratio Chart: Shows how the market values a company's assets over time. A PB ratio below its historical average may signal undervaluation.
- Compare within sectors: A PE of 30 might be cheap for a tech company but expensive for a utility. Always compare ratios within the same industry .
What is a Good PB Ratio?
There is no universal answer. It depends on the sector .
- For banks and financial companies: PB ratios between 1 and 3 are common. A PB below 1 may signal undervaluation. A PB above 3 may signal overvaluation .
- For manufacturing and real estate: PB ratios between 1 and 3 are reasonable. These companies have tangible assets that back the book value .
- For tech and service companies: PB ratios are often above 3. These companies have few physical assets. Their value comes from intangible assets. A high PB does not mean overvalued .
- For FMCG companies: PB ratios of 1 to 2 are considered fair in India .
A good PB ratio depends on the company's return on equity (ROE). Companies with high ROE can justify higher PB ratios. Companies with low ROE should trade at lower PB ratios .
