When investors want to know if a stock is fairly priced, they rarely look at it in isolation. Instead, they ask: "How much are similar companies trading for?" This approach is the foundation of comparable company analysis (often called "comps" or relative valuation).
Comparable company analysis is a relative valuation method in which a company's implied value is derived from the prices paid for similar companies in the market. Unlike absolute valuation methods like Discounted Cash Flow (DCF) that rely on complex forecasts of future cash flows, comps rely on current market pricing.
In this guide, we will walk through how to use comparable company analysis, the key valuation multiples involved, and how tools like Atlantis can streamline your research process.
Why Use Comparable Company Analysis?
The core premise of comparable company analysis is that similar companies provide a highly informative point of reference. If two companies operate in the same industry, have similar growth rates, and face similar risks, they should theoretically trade at similar valuation multiples.
Investors use comps because they are:
- Market-Based: They reflect current market sentiment and actual prices investors are willing to pay today.
- Relatively Simple: They require fewer assumptions than complex DCF models.
- Widely Used: They are the standard language of Wall Street analysts and institutional investors.
However, relative valuation has a major blind spot: if the entire sector is overvalued (like tech stocks during the dot-com bubble), comps will simply tell you which overvalued stock is slightly less overvalued than its peers.
The 5-Step Process for Comparable Company Analysis
Conducting a thorough comparable company analysis involves a systematic approach to ensure you are comparing "apples to apples."
Step 1: Select the Peer Group
This is the most critical step. If you choose the wrong peers, your entire analysis will be flawed. You want to find publicly traded companies that closely resemble your target company.
Key criteria for selecting peers include:
- Industry and Sector: They should operate in the same core business.
- Size: Look for similar market capitalization and revenue scale.
- Geography: Companies in emerging markets trade at different multiples than those in developed markets.
- Growth and Profitability: Similar historical and projected growth rates and margin profiles.
For example, if you are valuing a fast-casual restaurant chain like Chipotle, you would compare it to other fast-casual chains (like Cava or Shake Shack), not to a traditional sit-down restaurant like Darden Restaurants or a massive fast-food franchisor like McDonald's.
Step 2: Gather Financial Data
Once you have your peer group (usually 5 to 10 companies), you need to gather their financial data. This includes:
- Current stock price and shares outstanding to calculate Market Capitalization.
- Total debt and cash to calculate Enterprise Value (EV).
- Key income statement metrics: Revenue, EBITDA, EBIT, and Net Income.
You can find this data in SEC filings (10-Ks and 10-Qs) or use an AI-powered stock analysis platform like Atlantis to instantly pull and normalize this data across your peer group.
Step 3: Calculate Valuation Multiples
Next, you calculate the valuation multiples for each company in your peer group. A valuation multiple is simply a measure of value (the numerator) divided by a financial metric (the denominator).
The most common multiples include:
- Price-to-Earnings (P/E): Market Cap / Net Income (or Stock Price / Earnings Per Share). Best for mature, profitable companies.
- EV/EBITDA: Enterprise Value / Earnings Before Interest, Taxes, Depreciation, and Amortization. This is the most widely used multiple because it is capital structure neutral (it ignores debt levels) and removes non-cash accounting impacts.
- EV/Revenue: Enterprise Value / Revenue. Often used for early-stage, high-growth companies that are not yet profitable.
Step 4: Determine the Peer Group Averages
After calculating the multiples for all peers, you find the median and mean (average) for the group. Analysts typically prefer the median, as it is less skewed by extreme outliers. You might also look at the 25th and 75th percentiles to establish a valuation range.
Step 5: Apply Multiples to the Target Company
Finally, you apply the peer group median multiple to the target company's financial metrics to find its implied valuation.
Example:Let's say you are valuing "Company X," which has an EBITDA of $50 million.
If the median EV/EBITDA multiple of its peer group is 12x, the implied Enterprise Value of Company X is:
- $50 million × 12 = $600 million.
From there, you can subtract debt and add cash to find the implied Equity Value, and divide by shares outstanding to find the implied share price.
Common Pitfalls to Avoid
While comps are powerful, investors often make a few common mistakes:
- Ignoring Capital Structure: Comparing the P/E ratios of two companies with vastly different debt levels is misleading. A highly levered company might have a lower P/E but carry significantly more financial risk. This is why EV/EBITDA is often preferred.
- Relying Only on Historical Data: Markets are forward-looking. Always look at forward multiples (based on next twelve months' estimates) rather than just trailing twelve months (TTM) data.
- Forcing Bad Comparisons: If a company has no true peers, don't force a comparison with loosely related businesses just to complete the model.
Streamlining Your Analysis
Building a comparable company analysis from scratch in Excel can be incredibly time-consuming. You have to scrub the financials for one-time charges, calendarize fiscal years, and constantly update stock prices.
This is where modern tools come in. By using an AI-driven platform, you can instantly generate peer groups, calculate forward and trailing multiples, and visualize how a stock compares to its industry.

FAQ
Q: What is the difference between relative valuation and absolute valuation?A: Relative valuation (like comps) determines a company's value by comparing it to similar assets in the market. Absolute valuation (like a DCF model) attempts to find the intrinsic value of a company based purely on its own projected future cash flows, regardless of what the market is doing.
Q: Why is EV/EBITDA often preferred over the P/E ratio in comparable company analysis?A: EV/EBITDA is preferred because it is capital structure neutral. It looks at the value of the entire enterprise (including debt) relative to its core operating cash flow. The P/E ratio only looks at equity value and can be heavily skewed by a company's debt levels and tax rates.
Q: How many companies should be included in a peer group for comps?A: A standard peer group typically includes 5 to 10 highly comparable companies. Including too few companies makes the median unreliable, while including too many usually means you are adding companies that aren't truly comparable to your target.
