Valuation Guide

Mastering Price Multiples

A step-by-step guide to relative valuation. Learn how to use P/E, P/S, and Enterprise Value multiples to find undervalued stocks by comparing them against their peers.

The Art of Peer Comparison

Valuation is rarely absolute. To know if a stock is "cheap" or "expensive," you must compare it to something else. This is called Relative Valuation.

How to Compare

Investors compare a company's valuation multiples (like P/E or EV/EBITDA) against:

  • Direct Competitors: Companies of similar size in the same industry.
  • Industry Averages: The median multiple for the entire sector.
  • Historical Averages: The company's own 5-year or 10-year average multiple.

The Goal: Find high-quality companies trading at multiples lower than their peers or their own history.

Level 1: The Classic

Price to Earnings (P/E)

The P/E ratio is the most widely used valuation metric. It simply measures how much you are paying for $1 of the company's earnings.

When to use it

Best for mature, stable companies with consistent profitability.

Watch out for

Earnings can be manipulated by accounting tricks. One-time gains can artificially lower P/E.

Formula: Stock Price / Earnings Per Share (EPS)

Level 2: Top Line Focus

Price to Sales (P/S)

When a company isn't profitable yet, P/E is useless. Enter the Price-to-Sales ratio. It values a company based on its revenue, which is harder to manipulate than earnings.

When to use it

Ideal for high-growth tech stocks, startups, or cyclical companies in a downturn.

The Caveat

Sales don't pay the bills—profits do. A low P/S means nothing if margins are permanently low.

Formula: Market Cap / Total Revenue
Level 3: The Truth Serum

Price to Free Cash Flow (P/FCF)

"Earnings are opinion, cash is fact." Free Cash Flow represents the actual cash generated that can be returned to shareholders. P/FCF is widely considered the premier valuation metric by value investors.

Why it's superior

It accounts for capital expenditures (CapEx) needed to maintain the business, unlike P/E.

EV/EBIT
Level 4: Capital Neutral

EV / EBIT Multiple

Now we step into Enterprise Value (EV) multiples. EV/EBIT allows you to compare companies with different debt levels and tax rates on an apples-to-apples basis.

The "Acquirer's Multiple"

It measures operating earnings yield relative to the total cost to buy the entire company (equity + debt).

Formula: Enterprise Value / EBIT
Level 5: Operating Proxy

EV / EBITDA

EBITDA adds back Depreciation and Amortization to EBIT. This metric is a proxy for raw operating cash flow before heavy machinery or intangible assets are paid for.

Heavy Industry Standard

Commonly used for capital-intensive industries (telecom, utilities) to compare operating efficiency without the noise of depreciation schedules.

Formula: Enterprise Value / EBITDA
