Warren Buffett's most-quoted line captures the foundation of investing: there's a difference between the price of a stock (today's market quote) and its value (estimated worth based on future cash flows). Markets routinely misprice both directions — over-enthusiasm pushes prices above value; pessimism pushes them below.
Valuation is the discipline of estimating what a stock is actually worth. Done well, it gives you a yardstick to judge whether today's price is a deal, fair, or overpriced. Done poorly, it gives false precision around faulty assumptions.
This article covers the four practical valuation methods Indian investors should know — relative valuation, DCF, asset-based, earnings-based — with real Indian examples and the strengths/weaknesses of each.
Why Value Stocks at All?
Three reasons valuation matters even though markets eventually price stocks correctly:
Timing of conviction: Knowing whether a stock is undervalued helps you buy more during corrections (when most retail panics)
Avoiding overpriced traps: Catching FOMO at the top of a cycle is the most common retail mistake — valuation discipline prevents it
Position sizing: Stronger conviction (deeper undervaluation) justifies larger positions; thin margin of safety = smaller positions
SEBI's 2024 data showing 70-91% retail loss rates is partly because most participants buy what's popular, not what's undervalued. Valuation is the antidote.
The Four Practical Valuation Methods
Method 1: Relative Valuation (PE, PB, EV/EBITDA)
Compare a stock's key ratios to peers and its own history. Fastest method.
PE Ratio: Price ÷ EPS. Compare to sector average and stock's 5-year median.
PB Ratio: Price ÷ Book Value. Most useful for banks, financial services, asset-heavy businesses.
EV/EBITDA: Enterprise Value ÷ EBITDA. Standardises for capital structure differences across companies.
EV/Sales: For unprofitable companies (loss-making but growing).
Example: HDFC Bank PE ~18x vs Nifty Bank sector average 16x. Slight premium = quality premium for stable franchise. If suddenly trading at PE 10x (deep discount), worth investigating why — either opportunity or fundamental deterioration.
Strength: Quick, market-based, easy to implement. Weakness: Garbage-in-garbage-out — if peer group is overvalued, your relative-cheap stock is still expensive in absolute terms.
Method 2: Discounted Cash Flow (DCF)
Project free cash flows for 5-10 years, calculate terminal value, discount all to present value at appropriate cost of capital. The textbook absolute valuation method.
Most rigorous theoretically
Highly sensitive to assumptions (small changes in growth rate or discount rate dramatically swing the result)
Works best for stable, predictable cash-flow businesses (HUL, ITC, Nestle)
Less reliable for cyclical, high-growth, or capital-intensive industries
See our detailed DCF guide and the DCF Calculator for hands-on practice.
Method 3: Asset-Based Valuation
Sum the value of tangible assets minus liabilities. Most relevant for:
Banks (price-to-book is essentially this approach)
Real estate companies (NAV = market value of properties minus debt)
Holding companies (sum-of-parts valuation)
Distressed or liquidation scenarios
Less useful for capital-light businesses (software, FMCG brands) where the bulk of value is intangible.
Method 4: Earnings-Based Multiples
Take normalised earnings (cyclically-adjusted, excluding one-offs) and apply an appropriate multiple based on growth and quality.
Example: a company with steady ₹20 EPS growing 12% might justifiably trade at 20x PE = ₹400 fair value. Compare to current price to judge.
Useful for getting a rough fair value quickly; depends entirely on the "appropriate multiple" judgment.
Triangulating — Combining Methods
No single method is perfect. Smart investors triangulate:
Run relative valuation first — quick sense of whether stock is cheap/fair/expensive vs peers and history
If interesting, do a DCF — get an absolute fair value estimate
For asset-heavy businesses, add an asset-based check
Sanity-check using a normalised earnings multiple
If multiple methods converge on similar fair value, conviction increases
If methods diverge wildly, identify why — often reveals key business drivers
The Buffett Approach:
Warren Buffett famously skips precise DCF math — he says "it's better to be approximately right than precisely wrong." His approach: identify quality businesses with durable competitive advantages, then make a rough fair value estimate. If price is dramatically below fair value (significant margin of safety), buy. Don't obsess over decimal-place precision in valuation models — the inputs are estimates anyway.
Common Valuation Mistakes
Using single ratio in isolation: A stock looking cheap on PE alone may be expensive on PB or EV/EBITDA. Always check multiple metrics.
Comparing across unrelated sectors: Banks trade at very different multiples than IT services. Compare only within sector.
Ignoring growth differential: A high-growth company deserves higher multiples. PE 30 for 25%-growth company is reasonable; PE 30 for flat-earnings company is expensive.
DCF false precision: Building a 15-line DCF and concluding fair value is ₹1,234.56. Reality: your inputs have 10-20% uncertainty, so your output does too. Use a fair value range, not a point estimate.
Anchoring on historical price: "Stock was ₹2,000 last year, now ₹1,500 — must be cheap." History is irrelevant to valuation. Only current fundamentals and future cash flows matter.
Buying based on valuation alone: Valuation tells you when not to buy (overvalued) or that you can buy (undervalued); it doesn't tell you the catalyst that will close the gap. Cheap stocks can stay cheap for years.

Next Step — Understanding Intrinsic Value
The concept underneath all valuation methods is "intrinsic value" — what a stock is fundamentally worth. Learn the concept, its origins (Graham, Buffett), and how to estimate it simply.
Use four complementary methods. (1) Relative valuation — compare PE, PB, EV/EBITDA to sector peers and historical averages. (2) Discounted cash flow (DCF) — project future free cash flows and discount to present value. (3) Asset-based — sum tangible asset value (works for banks, real estate). (4) Earnings-based — multiply normalised earnings by appropriate multiple. No single method is universally correct. The goal is to triangulate a rough fair value range, then compare to current price. Buying at significant discount to your estimated fair value (margin of safety) is the core of value investing.
Relative valuation is the simplest method: compare a stock's PE, PB, and EV/EBITDA to its sector peers and historical average. If a stock trades at PE 12 in a sector with 20-25 average and the company's own 5-year average PE is 18, it appears cheap on a relative basis. Then dig deeper: why? Sometimes it's a value trap (business deteriorating), sometimes a genuine opportunity. Relative valuation gives you the starting signal; the deeper why-analysis is what separates good value investors from average ones.
Price is what you pay; value is what you get. Price is the current market quote, set by daily supply/demand and sentiment. Value (intrinsic value) is the present value of the company's future cash flows — an estimate, not a market quote. The two diverge frequently. Buying when price < estimated value with adequate margin of safety is value investing (Buffett, Graham). Markets are voting machines short-term, weighing machines long-term — price eventually converges to value, but the convergence can take years.

Honest answer: for 95% of retail investors, low-cost index funds beat self-valuation. SPIVA India data shows 70-90% of professional active fund managers underperform indices over 10 years — and they have research teams. Self-valuing stocks is a worthwhile skill to learn, but only if you have time, interest, and discipline to make it your edge. For wealth building, index funds + a small allocation (10-20%) to high-conviction individual picks is the practical retail approach. Don't make individual stock picking your primary wealth strategy unless you have proven multi-year track record.
For active stock-picking portfolios, 15-25 stocks is the sweet spot for retail. Fewer than 10 = excessive concentration risk; more than 30 = too diluted (you become a closet index fund without the cost advantage). Research shows most diversification benefit is captured at 15-20 stocks across different sectors. Top investors like Warren Buffett hold concentrated portfolios (~10 stocks) because they have deep conviction; most retail lacks this conviction and benefits from 15-25 names with strict position sizing (no single stock above 8-10% of portfolio).
