Determining the intrinsic value of a stock is often described as both an art and a science. While market sentiment can drive prices wild in the short term, long-term valuation usually rests on a company’s ability to generate profits and cash.
To move beyond speculation, investors use specific valuation frameworks to determine what a stock is actually worth.
1. The P/E Multiple Approach: Assigning a Target Price
One of the most common ways to assign a price to a stock is the Price-to-Earnings (P/E) Multiple method. This formula assumes that a stock’s value is a function of its current earnings power relative to its industry peers.
The Formula
To find the target price, you multiply the company’s Earnings Per Share (EPS) by a justified P/E ratio.
Price = EPS x P/E
Determining the “Hypothetical” P/E
You shouldn’t just use any number. To find a fair P/E, you look at the industry average or the company’s historical trading range.
Industry Benchmarking
If a software company is growing at 15% and the average P/E for the software sector is 25, applying that 25x multiple to the company’s EPS gives you a “fair” market price.
Business Example: Toyota vs. Ferrari
Consider Toyota versus Ferrari. While both are car manufacturers, they trade at vastly different multiples. Toyota often trades at a P/E between 8 and 12 due to high capital intensity and steady growth. Ferrari, positioned as a luxury brand with higher margins, often commands a P/E of 40 or higher. To price Ferrari using Toyota’s multiple would lead to a massive undervaluation because the business models differ in quality and scale.
2. Establishing the Floor: Free Cash Flow Per Share
If the P/E ratio tells you what a stock could be worth, Free Cash Flow (FCF) tells you what it is worth at a minimum.
Free Cash Flow is the cash a company generates after accounting for cash outflows to support operations and maintain its capital assets. Unlike “Earnings,” which can be manipulated by accounting tricks (depreciation, amortization, etc.), FCF is cold, hard cash.
Why FCF is the Floor?
The “floor” of a stock is often seen as its FCF Yield. If a company is generating massive amounts of cash per share and the stock price drops too low, the FCF yield becomes so high that the company can easily:
- Buy back all its own shares.
- Pay out massive dividends.
- Become an irresistible acquisition target for a competitor.
Business Example: Apple and Microsoft In the early 2010s, Apple traded at very low P/E multiples despite having a mountain of cash. Analysts looked at its FCF per share and realized the "floor" was incredibly high—the company was generating so much cash that the business was being valued at nearly the same level as the cash it held. This provided a "safety net" for investors; even if growth slowed, the cash flow alone justified the price.
3. The Discounted Cash Flow (DCF) Model
For a more comprehensive valuation, professional analysts use the DCF model. This method suggests that a stock is worth the sum of all its future cash flows, discounted back to their value today.
The logic is simple: a dollar today is worth more than a dollar tomorrow. By using a discount rate (usually the cost of capital), you can determine the Net Present Value (NPV) of the business.
Key Variables in DCF
- Terminal Value: The value of the company beyond the projection period (usually 5–10 years).
- Discount Rate: Often calculated using the Weighted Average Cost of Capital (WACC).
