The price of a stock is simple. It's the number you see next to the ticker symbol, changing second by second. But a stock's value is a completely different story. A stock's price is what you pay, but its value is what you get. Stock valuation is the process of figuring out that true, underlying worth.

Why does this matter? Because successful investing is about buying things for less than they are worth. Think of it like buying a used car. You wouldn't just pay the sticker price without doing some research. You'd check its condition, its mileage, and what similar cars are selling for. You want to make sure you're getting a fair deal.

Stock valuation is that research. It helps you look past the market's daily mood swings and hype to form your own opinion on a company's fair price. By estimating a stock's true value, you can decide if it's currently a bargain (undervalued), overpriced (overvalued), or just right (fairly valued).

Analysts generally follow two main paths to determine a stock's value. There's no single right way, and many investors use a combination of both.

The first path is intrinsic valuation. This method tries to calculate the value of a company based on its own financial health and ability to make money. It’s an inward-looking approach.

The second path is relative valuation. This method compares a company to its peers. How is this stock priced compared to similar companies in the same industry? It’s an outward-looking, comparative approach.

Intrinsic value is the worth of a business based purely on its own merits. It's an estimate of what the company is worth based on the cash it can generate for its owners in the future. This approach ignores the current stock price and market sentiment, focusing instead on the company's fundamental strengths.

The most common way to calculate intrinsic value is through a Discounted Cash Flow (DCF) analysis. The idea is simple, even if the math can get complex. You estimate all the cash the company is going to produce for the rest of its life, and then you calculate what that future stream of cash is worth in today's dollars. After all, a dollar tomorrow is worth less than a dollar today.

This final number is your estimate of the company's intrinsic value. If it's higher than the current stock price, you might have found a bargain.

Relative valuation is more straightforward. Instead of trying to calculate a precise value from scratch, you just compare the company's stock price to that of its competitors using a common yardstick.

Imagine you're buying a three-bedroom house. You'd want to know what other three-bedroom houses in the same neighborhood have sold for recently. This gives you a benchmark for a fair price. Relative valuation does the same for stocks.

This is done using valuation multiples. One of the most famous is the Price-to-Earnings (P/E) ratio. It tells you how much investors are willing to pay for each dollar of a company's earnings. By comparing the P/E ratios of, say, Ford and General Motors, you can get a sense of which stock might be cheaper relative to its earnings.

Other common multiples include Price-to-Sales (P/S) and Price-to-Book (P/B). Each one offers a different angle for comparing companies. The key is to compare apples to apples—that is, companies that are similar in size, industry, and growth prospects.

Here's a quick look at the two approaches side-by-side:

Now that you understand the core ideas of stock valuation, you're ready to start exploring the specific tools investors use to find the true value of a company.
