How different methods estimate what a company is worth relative to its current market price.
Valuation is the process of estimating a company's worth -- determining whether a stock's price is high, low, or roughly in line with its fundamentals. No single valuation method is definitive; most analysis uses multiple approaches to triangulate a range.
The structural challenge of valuation is that every method depends on assumptions, and different assumptions produce different estimates. Understanding what each method captures -- and what it misses -- is more useful than any single number.
Deep Value
Stock trading below tangible asset value with balance sheet safety
Relative Valuation
Comparing a company to similar businesses using multiples:
Price Multiples
- P/E (Price to Earnings): Most common, compares price to earnings per share
- P/S (Price to Sales): Useful for unprofitable companies or those with volatile earnings
- P/B (Price to Book): Relevant for asset-heavy businesses like banks
- P/CF (Price to Cash Flow): More reliable than earnings for some industries
Enterprise Value Multiples
- EV/EBITDA: Compares total business value to operating cash proxy
- EV/Revenue: Useful for growth companies or loss-making businesses
- EV/EBIT: Includes depreciation, more conservative than EBITDA
Absolute Valuation
Estimating intrinsic value independently of peers:
Discounted Cash Flow (DCF)
- Project future free cash flows
- Discount to present value using cost of capital
- Sum to determine enterprise value
- Theoretically sound but sensitive to assumptions about growth rates and discount rates
Dividend Discount Model
- Value based on expected future dividend payments
- Appropriate for mature, stable dividend payers
- Less applicable for growth companies reinvesting earnings
Key Valuation Metrics
Price-to-Earnings (P/E)
P/E = Stock Price / Earnings Per Share
- Trailing P/E: Based on past 12 months earnings
- Forward P/E: Based on analyst estimates for next 12 months
- PEG ratio: P/E divided by earnings growth rate -- adjusts for growth
Enterprise Value to EBITDA
EV/EBITDA = Enterprise Value / EBITDA
Useful because it ignores capital structure differences, excludes non-cash depreciation, and facilitates acquisition analysis.
Price-to-Book
P/B = Stock Price / Book Value Per Share
Particularly relevant for financial companies, asset-heavy businesses, and deep value analysis.
What Affects Valuation Multiples
Growth
Faster-growing companies tend to trade at higher multiples, reflecting greater expected future earnings:
- Revenue and earnings growth rates
- Addressable market size and penetration
- Competitive position and market share trends
Profitability
More profitable companies tend to command premiums:
- Higher margins indicating pricing power
- Superior returns on invested capital
- Sustainable competitive advantages
Risk
Lower perceived risk tends to correspond with higher valuations:
- Earnings stability and predictability
- Balance sheet strength and low leverage
- Favorable industry dynamics
Common Valuation Pitfalls
- Anchoring: Relying too heavily on past prices or previous valuations
- Recency bias: Overweighting recent results in projections
- Ignoring quality: Low multiples may reflect deteriorating fundamentals rather than opportunity
- Over-precision: False confidence in exact estimates when uncertainty is high
- Ignoring context: Missing industry cycles or macroeconomic factors
Valuation metrics describe the current relationship between a company's market price and its financial characteristics. They do not determine whether a stock is a good or bad investment, nor do they predict future price direction. Every valuation method embeds assumptions, and the assumptions matter as much as the output.
