DCF vs Relative Valuation: Which Method Should Investors Use?

When analyzing a stock, investors typically rely on two primary approaches: Discounted Cash Flow (DCF) and relative valuation (also known as comparable company analysis or multiples). Both methods aim to determine what a company is worth, but they approach the problem from entirely different angles.

Understanding the difference between DCF vs relative valuation is crucial for building a robust stock analysis workflow. While one method focuses on the fundamental cash-generating ability of a business, the other looks at what the market is currently willing to pay for similar assets. In this guide, we will compare both methods, explore their pros and cons, and explain when investors should use each approach.

What is DCF Valuation?

Discounted Cash Flow (DCF) is an intrinsic valuation method. It calculates the "true" value of a company based solely on its fundamentals, specifically its ability to generate free cash flow in the future. The core premise of a DCF model is that the value of a business today is equal to the present value of all the cash it will produce in the future, discounted back to today's dollars using a specific discount rate (often the Weighted Average Cost of Capital, or WACC).

Because DCF valuation looks inward at the company's own financial statements rather than outward at market trends, it is considered the purest form of fundamental analysis.

Pros of DCF Valuation

Focuses on Fundamentals: DCF relies on the actual cash flows a business generates, making it less susceptible to short-term market moods or irrational exuberance.
Highly Detailed: Building a DCF requires investors to think deeply about a company's revenue growth, profit margins, capital expenditures, and tax rates.
Independent of Market Pricing: If the entire stock market is overvalued, relative valuation will make an overvalued stock look "fairly priced" compared to its peers. A DCF model will correctly identify that the stock is too expensive based on its cash flows.

Cons of DCF Valuation

Sensitive to Assumptions: A DCF model requires forecasting cash flows 5 to 10 years into the future. A small change in the assumed growth rate or discount rate can drastically alter the final valuation.
Terminal Value Reliance: In most DCF models, the "terminal value" (the estimated value of the company after the 5-10 year forecast period) accounts for 60% to 80% of the total valuation. If this single assumption is wrong, the entire model is flawed.
Not Suitable for All Companies: DCF works best for mature companies with predictable cash flows. It is notoriously difficult to use for high-growth startups, companies with negative cash flows, or highly cyclical businesses.

What is Relative Valuation?

Relative valuation, often called comparable company analysis or multiples valuation, determines a company's value by comparing it to similar businesses in the same industry. Instead of projecting future cash flows, this method uses price multiples—such as the Price-to-Earnings (P/E) ratio, enterprise value-to-EBITDA (EV/EBITDA), or Price-to-Sales (P/S) ratio—to benchmark a stock against its peers.

The logic behind relative valuation is the Law of One Price: similar assets should sell for similar prices. If a software company is trading at a P/E of 15x while its direct competitors are trading at a P/E of 25x, the company might be undervalued.

Pros of Relative Valuation

Market-Informed: Relative valuation reflects current market realities. It tells you exactly what investors are willing to pay for a specific type of business today.
Quick and Efficient: Calculating a P/E ratio or EV/EBITDA multiple takes minutes, whereas building a robust DCF model can take hours or days.
Fewer Assumptions: Because it relies on current financial data and observable market prices, relative valuation requires far fewer long-term forecasts than a DCF model.

Cons of Relative Valuation

Finding True Peers is Difficult: No two companies are exactly alike. Differences in growth rates, profit margins, capital structure, and management quality can make direct comparisons misleading.
Vulnerable to Market Bubbles: During a market bubble, an entire sector might be drastically overvalued. Relative valuation might suggest a stock is "cheap" compared to its peers, even though the entire peer group is dangerously expensive.
Ignores intrinsic value: A stock might look fairly valued compared to its peers, but if the underlying business is deteriorating and cash flows are shrinking, the stock is still a poor investment.

DCF vs Relative Valuation: When to Use Each

The best stock analysis workflows do not rely on just one method. Instead, smart investors use both approaches to triangulate a fair value range. However, certain situations call for one method over the other.

When to Use DCF Valuation

You should prioritize a DCF model when analyzing mature, stable companies with predictable cash flows. For example, consumer staples, utility companies, and established tech giants like Microsoft or Apple are excellent candidates for DCF analysis.

If you are a long-term value investor looking to buy and hold a stock for a decade, DCF is the superior method because it focuses on the cash the business will return to you over time, regardless of what the stock market does next week.

When to Use Relative Valuation

Relative valuation is ideal when you need to quickly screen a large number of stocks or when analyzing companies with unpredictable cash flows. It is particularly useful for high-growth tech companies, early-stage biotech firms, or cyclical businesses (like airlines or semiconductor manufacturers) where forecasting 10 years of cash flows is nearly impossible.

If you are trying to decide between two very similar companies in the same industry—for example, choosing between Visa and Mastercard—relative valuation provides a clear, immediate comparison.

Combining Both Methods with AI

The most effective way to value a stock is to use both methods. If a DCF model suggests a stock is worth $100, and relative valuation suggests it is worth $110, you have a high degree of confidence in that valuation range. If the DCF says $50 but the market is paying $150, you know you need to investigate further—either your DCF assumptions are too pessimistic, or the market is caught in a speculative bubble.

Historically, running both types of analysis required significant time and spreadsheet expertise. Today, platforms like Atlantis use AI to automate the heavy lifting. With Atlantis, you can instantly generate DCF models with sensible baseline assumptions, while simultaneously pulling real-time comparable company multiples.

By leveraging AI investing tools, you can spend less time building spreadsheets and more time actually analyzing the business. Ready to upgrade your stock analysis workflow? Sign up for Atlantis today and explore more insights on our blog.

Frequently Asked Questions

Q: Which valuation method is more accurate, DCF or relative valuation?

A: Neither method is perfectly accurate on its own. DCF is theoretically more sound because it focuses on intrinsic cash flows, but it is highly sensitive to assumptions. Relative valuation is more practical and reflects current market prices, but it can be distorted by market bubbles. The most accurate approach is to use both methods together.

Q: Can I use a DCF model for a company that doesn't pay dividends?

A: Yes. A DCF model values a company based on its Free Cash Flow (FCF), which is the cash generated by the business after accounting for capital expenditures. A company does not need to pay a dividend to have positive free cash flow.

Q: Why do analysts use EV/EBITDA instead of the P/E ratio for relative valuation?

A: EV/EBITDA is often preferred because it accounts for a company's entire capital structure (both debt and equity) and ignores the impact of non-cash expenses like depreciation and amortization. This makes it easier to compare companies with different levels of debt or different tax situations.
