Stock Valuation 101: DCF, P/E Multiple, and Enterprise Value Decoded | UpMyFolio

What is a Stock Really Worth?

Price is what you pay; value is what you get. A stock trading at ₹100 is not necessarily cheaper than a stock trading at ₹5,000. True value is determined by the present value of all future cash flows the business can return to its owners between now and judgment day.

Understanding valuation prevents you from overpaying for great businesses and falling into cheap value traps.

1. Relative Valuation: The Price-to-Earnings (P/E) Ratio

The most widely quoted valuation multiple:

$$\text{P/E Ratio} = \frac{\text{Market Price Per Share}}{\text{Earnings Per Share (EPS)}}$$

When P/E is Useful vs. Dangerous

Useful: Comparing established, non-cyclical businesses within the same sector (e.g., comparing Dabur vs. Marico vs. Godrej Consumer).
Dangerous: Cyclical businesses (steel, commodities, shipping). Cyclicals show their lowest P/E at the top of the economic boom (when earnings peak) and their highest P/E at the bottom of the slump.

The PEG Ratio (Price/Earnings to Growth)

To adjust P/E for earnings growth, calculate the PEG ratio: $$\text{PEG} = \frac{\text{P/E Ratio}}{\text{Annual EPS Growth Rate (%)}}$$

PEG < 1.0: Generally considered undervalued relative to its growth trajectory.
PEG > 2.0: Indicates the market has priced in aggressive future expansion.

2. Enterprise Value to EBITDA (EV/EBITDA)

When comparing companies with significantly different debt capital structures, EV/EBITDA is vastly superior to P/E:

$$\text{Enterprise Value (EV)} = \text{Market Capitalization} + \text{Total Debt} - \text{Cash & Equivalents}$$

$$\text{EV/EBITDA Multiple} = \frac{\text{Enterprise Value}}{\text{EBITDA}}$$

Because Enterprise Value accounts for debt obligations, a company that looks deceptively cheap on a P/E basis will immediately reveal its true cost when debt is added back.

3. Absolute Valuation: Discounted Cash Flow (DCF)

The gold standard of fundamental intrinsic valuation. A DCF model projects future Free Cash Flows (FCF) over 5 to 10 years and discounts them back to today's rupees using the Weighted Average Cost of Capital (WACC).

$$\text{Intrinsic Value} = \sum_{t=1}^{n} \frac{\text{FCF}_t}{(1 + r)^t} + \frac{\text{Terminal Value}}{(1 + r)^n}$$

Key Components of a DCF Model:

Initial Free Cash Flow: Operating cash flow minus capital expenditures.
Growth Rate ($g$): Realistic projected revenue and profit growth. Conservative analysts use 10-15% for high-growth phases.
Discount Rate ($r$): The opportunity cost of capital (typically 11% to 13% for Indian equities).
Terminal Growth Rate: Expected growth in perpetuity, which should never exceed the long-term GDP growth rate of India (typically 4% to 5.5%).

The Concept of Margin of Safety

Benjamin Graham, the father of value investing, called the Margin of Safety the central secret of sound investing.

If your DCF calculation estimates a stock's intrinsic value at ₹1,000 per share, you should not purchase it at ₹980. Why? Because economic forecasts are inherently uncertain. By requiring a 25% to 35% discount to your estimated intrinsic value (buying at ₹650 to ₹750), you protect your capital against analytical error, unexpected industry shocks, or management missteps.

Valuation Summary Table

Valuation Method	Primary Metric	Best Suited For	Main Limitation
P/E Ratio	Price / EPS	FMCG, Pharma, IT	Distorted by debt and one-off accounting items
EV / EBITDA	Enterprise Value / Cash Profit	Telecom, Steel, Infrastructure	Ignores ongoing capital expenditure demands
P / B Ratio	Price / Book Value	Banks, NBFCs, Insurance	Useless for asset-light software or brand businesses
DCF Model	Discounted Cash Flows	Mature, predictable businesses	Highly sensitive to small changes in growth & discount rates
