This famous aphorism, popularized by the legendary investor Warren Buffett, is the absolute cornerstone of value investing. It elegantly captures the critical distinction between an asset's market price and its underlying worth. The 'price' is the figure you see on your screen—the current stock quote, the cost of a bond, or the asking price for a piece of real estate. It’s a simple, concrete number determined by the whims of the market. 'Value,' on the other hand, is a more complex concept. It represents the true, underlying worth of the asset, often called its intrinsic value. This is the value you, as a thoughtful investor, would place on the business based on its long-term earnings potential and financial health. The core of value investing is not to chase rising prices but to identify and buy assets when their price is significantly lower than their calculated value. This simple phrase serves as a constant reminder to look past the market noise and focus on the quality and worth of what you are actually buying.
Understanding this distinction is what separates successful long-term investors from short-term speculators. They are two different things driven by entirely different forces.
The price is the market's consensus at any given moment. It’s what someone is willing to sell an asset for and what someone else is willing to pay. It can be swayed by a multitude of short-term factors:
A key insight from Benjamin Graham, Buffett's mentor, is to view the market as a moody business partner he called Mr. Market. Some days, Mr. Market is euphoric and offers to sell you shares at ridiculously high prices. On other days, he's despondent and offers you the same shares at a steep discount. The price is simply Mr. Market’s mood on any given day; it is not a reliable indicator of the business's actual worth.
Value is an estimate of a company's true worth, independent of its stock price. It’s what the business would be worth to a rational, private owner. Calculating this intrinsic value is the primary job of a value investor. While there's no single magic formula, it's typically determined by analyzing a company's fundamentals, such as:
Methods like a Discounted Cash Flow (DCF) analysis are used to project a company's future earnings and discount them back to today's money to arrive at a present value. Crucially, value is an estimate. It requires judgment and conservative assumptions. The goal isn't to find a precise number but to determine a reasonable range of what the business is truly worth.
Knowing the difference between price and value is useless without a plan of action. The goal is to buy value for less than its price, creating what Benjamin Graham called a Margin of Safety.
Imagine finding a high-quality, all-weather coat that you know is worth €300. One day, you walk past the store and see it on sale for €150. The price (€150) is what you pay. The value (€300) is what you get. The €150 difference is your margin of safety. It's the buffer that protects you. Even if your value estimate was a bit optimistic and the coat is only worth €250, you still got a fantastic deal. In investing, the margin of safety works the same way. It’s the discount between the market price and your conservative estimate of intrinsic value. A large margin of safety protects your investment from:
Let's say “Global Tech Innovators” stock is trading at $100 per share. After extensive research, you conservatively estimate its intrinsic value to be $150 per share.
By buying at $100, you are not only acquiring a piece of a great business but also doing so with a significant cushion against potential trouble. This is the essence of professional, business-like investing.
Finally, internalizing this mantra helps you sidestep two of the most common investment mistakes.
