/learn/pe-ratio-valuationKey Stock Ratios: P/E, P/B, ROE & Dividend Yield
Master the four cornerstone valuation and profitability metrics used by seasoned investors to determine if a stock is a bargain, fairly priced, or a dangerous value trap.
- ✓P/E (Price-to-Earnings) reveals how many rupees you pay for ₹1 of annual company net profit. It gauges market growth expectations and flags valuation bubbles.
- ✓P/B (Price-to-Book) compares market capitalization to tangible net assets. It is the primary metric for banks and NBFCs, but unhelpful for asset-light tech and FMCG companies.
- ✓ROE (Return on Equity) measures management’s compounding efficiency with shareholder capital. Over the long run, investor returns closely mirror sustained business ROE.
- ✓Dividend Yield measures annual cash returns per share. Beware of "yield traps" where a crashing stock price artificially inflates trailing dividend yields.
- ✓The Golden Synergy Rule: Never evaluate any ratio in isolation. Use P/E and P/B to assess price, ROE and ROCE to verify quality, and Dividend Payout to verify cash reality.
#1Ratio 1: P/E Ratio (Price-to-Earnings) — What You Pay for ₹1 of Profit
Imagine two neighborhood shops in your city:
🏪 1. Sharmaji's Daily Kirana Store (FMCG Archetype):
🏬 2. Vermaji's Seasonal Wedding Sherwani Tailor (Cyclical Commodity Archetype):
Trailing (TTM) vs Forward P/E
Valuation Trap Watch• Trailing P/E is grounded in concrete, audited facts from the past 12 months. However, it looks backward into the rearview mirror. • Forward P/E reflects future optimism. When analysts predict a company’s profits will surge 50%, a stock with a 30x TTM P/E appears to have an attractive "Forward P/E" of only 20x. • Risk: Indian brokerage analysts are notoriously optimistic during bull markets. If the projected profit boom fails to materialize, the stock crashes as its multiple compresses!
Sector Baselines: Why FMCG Trades at 60x and Steel at 8x
Context Matters• FMCG (HUL, Nestle, Britannia): Trades at 50x–70x P/E because daily consumption (soap, tea, biscuits) is virtually immune to recessions, generates negative working capital, and requires zero debt. • IT Services (TCS, Infosys): Trades at 22x–30x P/E due to predictable dollar-denominated multi-year enterprise contracts and 80%+ cash conversion. • Cyclical / Commodities (Tata Steel, Vedanta): Trades at 6x–10x P/E at peak commodity prices. Counter-intuitively, cyclical commodity stocks are most dangerous when their P/E looks cheapest!
The P/E Value Trap
Danger Signal• A stock trading at a single-digit P/E (e.g., 6x) is not automatically a bargain. It could be a "Value Trap" — a company facing technological obsolescence, loss of market share, corporate governance misconduct, or one-off asset sale profits that will never recur. • Golden Rule: A high-quality company at 25x P/E with a 20% sustainable growth runway is vastly superior to a dying business at 7x P/E with zero growth.
The Peter Lynch PEG Ratio
Growth vs Value• Developed by legendary Fidelity Magellan fund manager Peter Lynch to bridge the gap between Value and Growth investing. • Formula: PEG = P/E Ratio ÷ Expected Annual EPS Growth Rate (%). • Example: Company A has a P/E of 30 and grows earnings at 35% annually (PEG = 30 ÷ 35 = 0.85). Company B has a P/E of 15 but grows at only 5% annually (PEG = 15 ÷ 5 = 3.0). • Company A is mathematically much cheaper relative to its growth engine!
#2Ratio 2: P/B Ratio (Price-to-Book) — Buying Net Assets vs Paying for Brand Air
Why Banks Live and Die by P/B
Financial Sector Core• A bank’s balance sheet IS its core business engine. It takes deposits (liabilities) and lends them out as mortgages, car loans, and corporate credit (assets). • Premium private banks (HDFC Bank, Kotak Bank, ICICI Bank) historically trade between 2.2x and 3.5x P/B because their underwriting discipline prevents loan defaults. • PSU Banks often trade between 0.8x and 1.5x P/B due to historic asset quality swings and government ownership constraints.
The Asset-Light Distortion
Accounting Reality• Standard accounting rules (Ind-AS / IFRS) do not allow companies to record internally generated brand value or software source code as assets on the balance sheet. • Titan, Asian Paints, and Nestle create enormous profits with very little physical capital employed. Their P/B ratios look sky-high (15x to 35x), but this is not a sign of overvaluation; it is a sign of an extraordinary economic moat!
The Danger of P/B < 1.0 (Value vs Distress)
Balance Sheet Audit• If a textile or steel mill trades at 0.4x P/B, retail investors assume they are buying a rupee for 40 paise. • Reality Check: If the factory machinery is 25 years old and technologically obsolete, it cannot be sold for scrap value. If inventory cannot be sold and receivables turn into bad debt, the real book value is actually zero! • Always verify whether the book value consists of real cash and performing loans or illiquid legacy junk.
Tangible Book Value (TBV)
Refined Metric• When a company acquires other businesses at an expensive premium, it creates an accounting item called "Goodwill" on its asset sheet. • Tangible Book Value per share subtracts Goodwill and intangible assets from total equity. • Using Price-to-Tangible-Book (P/TBV) protects conservative investors from sudden write-downs when past overpriced acquisitions fail.
#3Ratio 3: ROE (Return on Equity) — Management's Compounding Engine
Consider two real-world Indian business models:
🥐 1. The D-Mart (Avenue Supermarts) Model — Asset Turnover Power:
🏢 2. The Infrastructure Developer Trap — Debt Leverage Illusion:
DuPont Analysis: Deconstructing ROE
Forensic ToolDuPont analysis breaks ROE down into three distinct operating drivers: 1. Net Profit Margin (PAT ÷ Revenue): Pricing power and cost discipline. 2. Asset Turnover (Revenue ÷ Total Assets): Asset efficiency — how many times assets turn into sales. 3. Equity Multiplier (Total Assets ÷ Equity): Financial leverage — how much bank debt is used. • High-quality ROE is powered by high margins (Titan) or high turnover (D-Mart), NOT by piling on debt!
The Leverage Illusion (Fake ROE)
Red Flag Alert• Example: Company X has ₹100 Cr Equity, ₹0 Debt, and makes ₹20 Cr Profit → ROE = 20%. • Company Y has ₹10 Cr Equity, ₹90 Cr Debt (Total capital ₹100 Cr), and makes ₹2.5 Cr Profit after paying heavy interest → ROE = ₹2.5 Cr ÷ ₹10 Cr = 25%! • An amateur screener ranks Company Y higher because 25% > 20%. In reality, Company Y is a debt-choked disaster one quarterly slowdown away from bankruptcy!
ROE vs ROCE (Return on Capital Employed)
Vital Distinction• ROE measures returns only on shareholder equity (PAT ÷ Net Worth). • ROCE measures operating profit generated from ALL long-term capital (EBIT ÷ [Equity + Long-term Debt]). • For companies with debt, ROCE is the superior metric because it cannot be artificially manipulated by borrowing money. Always check both ROE and ROCE together.
The Reinvestment Compounding Equation
Wealth Multiplier• A company cannot grow intrinsic value faster than its Return on Equity unless it raises external capital. • Intrinsic Growth Rate = ROE × (1 – Dividend Payout Ratio). • If an Indian franchise earns 28% ROE and retains 75% of profits (paying out 25% as dividend), its earnings compounding engine runs at 28% × 0.75 = 21% per year!
#4Ratio 4: Dividend Yield & Payout — Cash in Hand vs Reinvestment
The Dividend Payout Ratio Health Check
Sustainability Metric• 0% to 20%: Typical for fast-growing small-caps and mid-caps reinvesting all earnings into new production capacity, hiring, and R&D. • 30% to 60%: Ideal balanced "sweet spot" for mature leaders (TCS, Infosys, ITC). Rewarding shareholders while funding future growth internally. • 80% to 100%+: Red flag warning! The company is paying out more than it retains, starving itself of future growth capital or taking on debt to maintain payout optics.
Spotting the High-Yield Trap
Retail Investor Danger• Retail investors frequently gravitate toward PSU commodity or paper companies yielding 9%–12%. • The Math Trap: Stock was ₹400 and paid ₹40 dividend (10% yield). Commodity prices crash, company profits drop 80%, stock price collapses to ₹160. • Next year, dividend is slashed to ₹4. The investor lost ₹240 in capital to earn ₹40 in dividends!
Taxation Realities for Indian Investors
Post-Tax Impact• Prior to 2020, Dividend Distribution Tax (DDT) was paid by companies. Today, dividends are taxed directly in the investor's hands at their slab rate. • For an investor in the 30% tax bracket, a 6% dividend yields only ~4.1% post-tax. • By contrast, long-term capital gains (LTCG) in Indian equities are taxed at a concessional 12.5% (above ₹1.25 Lakhs exemption). Growth compounding is vastly more tax-efficient!
Dividends as an Accounting Truth Serum
Forensic Hygiene• Unethical promoters can inflate reported earnings through fake debtor entries, capitalized expenses, or premature revenue recognition. • However, a company that has paid steady, growing cash dividends into shareholder bank accounts for 15 consecutive years proves that its reported profits are backed by cold, hard cash flow.

Demat RequiredThe Sustainable Cash Flow & Dividend Screen
Demat Required- ✓Objective Screening: Instantly filters through 5,000+ listed NSE/BSE companies to find candidates worthy of deep investigation.
- ✓Prevents Valuation Euphoria: Buying companies with extreme triple-digit P/E multiples historically leads to prolonged periods of stagnation.
- ✓Quality Separation: ROE and ROCE instantly distinguish high-moat wealth compounding franchises from commodity businesses.
- ✓Cash Verification: Dividend history and payout ratios act as an accounting truth serum verifying reported net profits.
- ✗Backward-Looking Nature: Ratios calculated on trailing data reflect the past 12 months, not what will happen in the next 3 years.
- ✗Accounting Discrepancies: Promoter-driven aggressive accounting (capitalizing expenses, changing depreciation methods) can distort EPS and Book Value.
- ✗Sector Incompatibilities: Applying the same P/E or P/B criteria across different industries leads to catastrophic errors (e.g., calling HUL expensive vs Tata Steel).
| Stock Ratio | Mathematical Formula | Core Question It Answers | Healthy Indian Benchmark | Primary Blindspot / When It Fails |
|---|---|---|---|---|
| P/E (Price-to-Earnings) | Market Price ÷ EPS | How many rupees am I paying for ₹1 of annual company profit? | 15x – 25x (Sector dependent) | Misleading for cyclical commodity peaks; blind to debt leverage; susceptible to one-off extraordinary gains. |
| P/B (Price-to-Book) | Share Price ÷ Book Value Per Share | How much am I paying relative to net liquidation asset value? | 1.5x – 3.0x for Banks; < 4.0x for asset-heavy | Completely useless for asset-light software, FMCG, and consumer franchises with massive intangible brand equity. |
| ROE (Return on Equity) | (Net Profit ÷ Shareholders' Equity) × 100 | How efficiently does management compound shareholder money? | > 15% to 20%+ (Must beat 12% Cost of Equity) | Can be artificially inflated by loading the balance sheet with dangerous bank debt (leverage illusion). |
| Dividend Yield | (Annual Dividend ÷ Current Price) × 100 | What cash yield does my bank account receive relative to price? | 1.5% – 4.0% for steady mature cash cows | The "Yield Trap": collapsing stock prices make declining cyclical businesses appear deceptively attractive. |
| PEG Ratio (Bonus Filter) | P/E Ratio ÷ Annual EPS Growth Rate (%) | Am I overpaying for expected profit growth? | < 1.0 (Bargain/Fair); > 2.0 (Expensive) | Relies entirely on estimated future growth projections which may fail to materialize in downcycles. |
| Criteria | P/E Ratio (Earnings Multiplier) | P/B Ratio (Balance Sheet Anchor) |
|---|---|---|
| Financial Statement Analyzed | Income Statement (Profit & Loss / EPS) | Balance Sheet (Assets minus Liabilities / Net Worth) |
| Best Suited Sectors | FMCG, Consumer, IT Services, Pharma, Auto | Banks, NBFCs, Housing Finance, Infrastructure, Utilities |
| Meaningless / Ineffective For | Loss-making companies or early-stage startups with ₹0 profits | Asset-light tech, internet platforms, digital media, IP-driven biotech |
| Impact of Excessive Debt | High interest payments artificially depress EPS, inflating P/E | Total liabilities reduce Book Value, making P/B appear very high |
| Key Diagnostic Trap | Value Trap (cheap 6x P/E due to permanent business decline) | Distress Trap (0.4x P/B because loan book or factories are junk) |
