Valuation

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.

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.
