Intrinsic value of a stock: 5 methods Indian investors should know

What is intrinsic value?

Intrinsic value is an estimate of what a business is worth based on its underlying economics — earnings power, asset base, capital structure, and the risks attached to its future cash flows. The concept was articulated by Benjamin Graham in Security Analysis (1934) and developed further by Warren Buffett, who has consistently framed it as the discounted value of all the cash a business will distribute to its owners over its remaining life. Intrinsic value is deliberately distinct from market price. The market price is what the stock historically trades at on NSE or BSE on any given day; the intrinsic value is what the business is illustratively worth based on first-principles analysis.

Crucially, intrinsic value is always an estimate within a range. Two competent analysts using different but defensible assumptions about revenue growth or discount rates will arrive at materially different numbers, and that is normal. The goal is not to compute a single precise figure but to bracket the value, compare the range to the current market price, and act only when the price sits comfortably below the lower end of the range — Graham's margin-of-safety principle.

Method 1: Discounted Cash Flow (DCF)

The DCF approach projects free cash flow for an explicit forecast horizon (typically five to ten years), assumes a perpetual growth rate beyond that horizon to estimate terminal value, and discounts everything back to today using a weighted average cost of capital. The advantage is theoretical purity — DCF is the most direct implementation of the "business value equals discounted future cash" idea. The disadvantage is sensitivity. Small changes in discount rate or terminal growth assumption produce large changes in the output.

For a deeper walkthrough including WACC construction and worked numbers, see the dedicated explainer on DCF valuation for Indian companies. For most stable Indian large-caps in 2026, DCF inputs typically use an 11 to 14 percent WACC and a 4 to 5 percent terminal growth rate. DCF is the right tool for businesses with predictable cash flows such as software services, consumer staples, and large pharma.

Method 2: Graham's formula

Benjamin Graham proposed a shortcut formula in The Intelligent Investor (1962 revision): V equals EPS multiplied by (8.5 plus 2g) multiplied by 4.4 divided by Y. Here EPS is the trailing twelve-month earnings per share, g is the expected long-term annual earnings growth rate (in percentage points), 8.5 is the no-growth P/E multiple Graham considered reasonable, 4.4 is the historical average AAA corporate bond yield Graham used for normalisation, and Y is the current AAA bond yield used as a proxy for the risk-free rate.

For an Indian application, Y is typically replaced with the current 10-year G-Sec yield. Take an illustrative consumer staple with EPS of ₹65, expected long-term growth of 10 percent, and a current 10-year G-Sec yield of 7 percent. Plugging in: V = 65 × (8.5 + 2 × 10) × 4.4 / 7 = 65 × 28.5 × 4.4 / 7 ≈ ₹1,164. That is the illustrative per-share intrinsic value implied by Graham's formula. The method's strength is simplicity — it requires only three inputs. Its weakness is that it relies on a stable growth assumption, breaks down for negative or very high growth rates, and uses a US-centric numerical anchor that may need recalibration for Indian conditions.

Method 3: Earnings Power Value (EPV)

Earnings Power Value, popularised by Bruce Greenwald at Columbia, is a no-growth valuation. The idea is to value a business based on its sustainable current earnings power, ignoring growth entirely. EPV equals normalised earnings divided by cost of capital, then adjusted for excess assets and net debt. The strength of EPV is intellectual honesty — it forces the analyst to value the business as it stands today, rather than relying on uncertain future growth assumptions.

EPV is particularly useful for cyclicals where reported earnings are either at a peak or trough relative to mid-cycle. The analyst normalises EBIT margins to a mid-cycle estimate, computes tax-adjusted operating profit, divides by cost of capital, and arrives at the value the business would command if it never grew. Comparing EPV to the DCF intrinsic value reveals how much of the DCF output depends on growth assumptions. If EPV is ₹1,000 per share and DCF is ₹1,500 per share, the implied "growth premium" is ₹500. That premium has to be earned through actual future growth; if growth disappoints, the stock historically reverts toward the EPV anchor.

Method 4: Asset-based valuation

Asset-based valuation values a business based on its balance sheet rather than its earnings. There are two common variants: book value and Graham's net-net. Book value is shareholders' equity divided by the share count — the accounting value of the company's assets net of liabilities. Net-net, Graham's deep-value approach, takes only current assets minus all liabilities, treating fixed assets as worthless. A net-net stock trades below the liquidation value of its working capital, which is historically a strong margin of safety.

Asset-based valuation is most useful for distressed companies, holding companies, real-estate-heavy businesses, and balance-sheet intensive firms like banks and insurers. It is least useful for asset-light businesses like software services, where the value resides in customer relationships and intellectual property that do not appear on the balance sheet. Indian listed holding companies typically trade at structural discounts to NAV, which is itself an asset-based valuation idea.

Method 5: Relative valuation

Relative valuation contextualises a stock against its peer group using multiples — P/E, EV/EBITDA, P/B, P/S, and EV/Sales are the most common. The mechanics are simple: pick a peer set of comparable listed Indian companies, compute the median multiple, apply it to the target's relevant accounting metric, and compare the implied value to the current market price. The advantage is discipline — relative valuation forces explicit comparisons rather than abstract DCF outputs. The disadvantage is that the entire peer set may be over-valued or under-valued together, in which case a relative valuation tells you only that the target is in line with peers, not whether peers themselves are fairly priced.

For Indian large-caps, the P/E ratio is the most commonly cited multiple, but EV/EBITDA is increasingly preferred because it is unaffected by capital structure and one-off items. PEG (P/E divided by growth rate) is a Lynch-style adjustment that scales the multiple by expected growth. None of these multiples are intrinsic-value calculations on their own — they are sanity checks against an absolute valuation method.

Margin of safety: Graham's 30 to 50 percent rule

No single intrinsic-value calculation should be acted on without a margin of safety. Graham's rule was straightforward: only act when the market price sits 30 to 50 percent below your calculated intrinsic value. The cushion absorbs estimation errors. If your intrinsic value is ₹1,000 and you require a 33 percent margin, you would only act below ₹670. If your assumptions are wrong by 20 percent, you still have a 13 percent buffer. Without the cushion, even small input errors translate directly into capital loss.

The required margin of safety scales with the riskiness and predictability of the business. A consumer staple with 30-year dividend history might need only 20 percent. A cyclical commodity stock with peak-to-trough EPS swings of 80 percent needs 40 to 50 percent. A loss-making early-stage firm with no clear path to profitability requires margins so large that most professional investors avoid the category altogether.

Common mistakes Indian retail investors make

The first mistake is anchoring on a single method. A DCF that says ₹1,500 per share and a peer-multiple comparison that says ₹600 per share is a disagreement that demands resolution, not a number to average. Either the DCF assumptions are too aggressive or the peers are mispriced. Either way, the analyst owes themselves an answer.

The second mistake is ignoring qualitative factors. A spreadsheet-perfect DCF for a company with weak corporate governance, related-party transactions, or a deteriorating competitive position is worth less than the paper it is printed on. Quantitative intrinsic value must be interpreted alongside qualitative business analysis.

The third mistake is false precision. Quoting an intrinsic value of ₹1,247.83 implies a level of accuracy the inputs cannot support. Practitioners discuss outputs in ranges — "the intrinsic value looks like ₹1,100 to ₹1,400 depending on growth assumptions" — and that range is the actual output of the analysis.

The fourth mistake is recency bias. An intrinsic-value model built using trailing-twelve-month earnings during a peak commodity cycle will materially overstate value because peak earnings are not sustainable. Use mid-cycle or normalised earnings for cyclicals.

The fifth mistake is ignoring the cash flow statement. Reported net income can be inflated by accounting choices, but operating cash flow is much harder to manipulate. Any intrinsic value calculation that ignores cash conversion is dangerously incomplete.
