P/B Ratio (Price-to-Book Ratio)
The Price-to-Book (P/B) ratio compares a company's market trading price to its Book Value Per Share (net worth per share), reflecting asset-backing safety.
Detailed Explanation
Book Value Per Share (Net Worth Per Share) represents the net accounting value of a company's tangible assets after satisfying all liabilities and debts. The Price-to-Book (P/B) ratio divides the current NEPSE market price by this book value. A P/B ratio close to 1.0x indicates that you are acquiring ownership at virtually the exact cost of the company's underlying net balance sheet assets. P/B is especially valuable when analyzing capital-heavy, asset-backed sectors such as commercial banking and insurance in Nepal.
Why It Matters to You
During market bear cycles, stocks often retreat toward their Book Value, creating a theoretical valuation floor. P/B helps investors identify deeply discounted financial stocks with high margin of safety.
Formula & Calculation
P/B Ratio = Current Market Price (CMP) / Book Value Per Share (BVPS)
- CMP = Current market price on NEPSE
- BVPS = Net Worth Per Share from the latest quarterly report
If a bank trades at NPR 260 and its Net Worth Per Share is NPR 175, P/B = 260 / 175 = 1.48x.
Where It Is Commonly Used
- Banking sector valuation
- Asset-heavy corporate screening
- Merger and acquisition swap ratio reviews
Key Advantages & Limitations
Key Advantages
- Provides a tangible valuation floor
- Less volatile than quarterly EPS
- Excellent for financial institutions
Limitations & Risks
- Book values can be overstated if bad loans are not written off promptly
Common Misconceptions & Beginner Traps
P/B can be used equally across all sectors.
P/B is ideal for banks and insurers with financial assets. It is less useful for service or tech companies whose value lies in intangible intellectual property.
Nepal Financial & Regulatory Context
In Nepal, every public company lists its Net Worth Per Share in mandatory quarterly press disclosures. Under SEBON rules, opening listing prices for newly listed IPOs are capped at a maximum of 3x book value.
Real-World Practical Scenario
Evaluating a commercial bank trading near book value. Current Market Price: NPR 185. Book Value Per Share: NPR 170. P/B Ratio: 185 / 170 = 1.08x. Assessment: Investor pays only an 8% premium above balance sheet liquidation value
High margin of safety if bad loans (NPL) are adequately provisioned.
