Investors use various financial ratios to evaluate whether a stock is fairly valued, undervalued, or overvalued. Among the most widely used valuation metrics are the Price-to-Earnings (PE) Ratio and the Price-to-Book (PB) Ratio. Understanding PE Ratio vs PB Ratio: Which One Matters More? can help investors make informed decisions when selecting stocks for their portfolios.
Both ratios serve different purposes and provide unique insights into a company’s valuation. In this article, we’ll explore PE Ratio vs PB Ratio: Which One Matters More?, their advantages, limitations, and how investors can use them effectively.
What is P/E Ratio (Price-to-Earnings Ratio)?
The P/E Ratio measures a company’s current share price relative to its earnings per share (EPS). It tells you how much investors are willing to pay for ₹1 of the company’s earnings.
Formula:
P/E Ratio = Market Price per Share ÷ Earnings Per Share (EPS)
Example:
If a stock is trading at ₹1,000 and its EPS is ₹50, then:
P/E = 1,000 ÷ 50 = 20
This means investors are paying ₹20 for every ₹1 of earnings.
What is P/B Ratio (Price-to-Book Ratio)?
The P/B Ratio compares a company’s market price to its book value (net asset value). It shows how much investors are paying for ₹1 of the company’s assets.
Formula:
P/B Ratio = Market Price per Share � Book Value per Share
Example:
If a stock is trading at ₹1,000 and its book value is ₹400, then:
P/B = 1,000 ÷ 400 = 2.5
This means investors are paying ₹2.5 for every ₹1 of assets.
Key Differences Between P/E and P/B Ratio
When is P/E Ratio More Important?
The P/E ratio is better when you’re evaluating:
✅ Profitable Companies
Companies with consistent earnings
Mature businesses with stable profit margins
✅ Growth Stocks

Companies like tech, FMCG often have higher P/E
✅ Comparing Similar Companies
Compare P/E within the same sector
FMCG: Often 40+ P/E
IT: 25-35 P/E
Banks: 10-15 P/E
✅ Forward-Looking Analysis

When is P/B Ratio More Important?
The P/B ratio is better when you’re evaluating:

Banks depend heavily on assets and liabilities (deposits, loans)

✅ Asset-Heavy Companies
Manufacturing, real estate, infrastructure
Companies with significant physical assets
✅ Value Investing
P/B below 1.0 may suggest undervaluation

When profits are temporarily low but assets remain strong
Why P/B Ratio is More Important for Banks

Example: For banks like HDFC Bank, ICICI Bank, P/B ratio (1-3) is more meaningful than P/E.
