Competition is the rivalry between companies selling similar products or services with the goal of achieving revenue, profit, and market share growth. From a Value Investing perspective, competition is the single most destructive force a business can face. Think of capitalism as a grand, ongoing battle for profits. In this battle, competition is the relentless force that pushes down prices, drives up costs for marketing and innovation, and ultimately erodes the profitability of all participants. A perfectly competitive industry is a nightmare for an investor, as no single company can earn sustainable, above-average returns. For this reason, legendary investors like Warren Buffett don't look for companies that are good at competing; they look for companies that, thanks to some durable advantage, don't have to. Understanding the competitive landscape is therefore not just an academic exercise—it's the first step in identifying a truly exceptional business worthy of your capital.
Imagine two businesses. Business A sells a unique, patented drug that cures a common ailment. Business B runs a small pizzeria in a city with hundreds of other pizzerias. Business A faces almost no direct competition and can set a price that ensures high profitability. Business B, however, is in a brutal street fight. If it raises its prices by a dollar, customers flock to the pizzeria across the street. It must constantly spend on local advertising and “2 for 1” deals just to keep customers coming in. As an investor, you want to own Business A, not Business B. The lack of competition allows Business A to generate high Return on Invested Capital (ROIC) year after year. Business B is lucky to break even. The core job of a value investor is to find businesses that are structurally shielded from the profit-destroying grind of intense competition.
To systematically analyze the competitive pressures on a company, investors often use a framework developed by Harvard professor Michael Porter called Porter's Five Forces. It's a fantastic tool for looking beyond just the direct rivals.
How easy is it for new companies to enter the industry and steal market share? If it's easy, profits will always be under pressure. The best businesses are protected by high Barriers to Entry, which act like a fence keeping competitors out. Examples include:
How much power do customers have to drive down prices? If a company sells its entire output to a single, massive customer (like Walmart or a national government), that buyer has immense leverage to demand lower prices and better terms. This is a weak position for a business to be in. The ideal business has a fragmented customer base where no single buyer is critical to its success.
The flip side of buyer power is Bargaining Power of Suppliers. If a company relies on a single, specialized supplier for a critical component (like a unique microchip), that supplier can raise its prices and squeeze the company's profits. Companies that control their own supply chain or have numerous competing suppliers are in a much stronger position.
This isn't about direct competitors, but about different ways to solve the same customer problem. For example, the substitute for a train ride isn't just another train company; it could be an airplane, a bus, or a car. The availability of cheap and easy substitutes puts a natural ceiling on how much a company can charge, no matter how dominant it is in its own specific market.
This is the most obvious force: the head-to-head scrap between existing players. This rivalry is most intense when:
Price wars are the ultimate expression of intense rivalry and are a reliable destroyer of shareholder wealth.
So, how does a company defend itself against these five forces? The answer is an Economic Moat. Coined by Warren Buffett, the term refers to a sustainable competitive advantage that protects a company's profits from the onslaught of competition, much like a real moat protects a castle. Finding companies with wide and durable moats is the cornerstone of long-term value investing. The primary types of Economic Moats are:
Analyzing competition isn't about finding the company that fights the hardest. It's about finding the company that doesn't have to fight at all. The presence of a wide, deep Economic Moat that neutralizes the destructive forces of competition is the clearest sign of a potentially wonderful business. A company that can consistently earn high returns on its capital without being ground down by rivals is a machine for creating long-term wealth for its owners. Your task as an investor is to find these castles and buy them at a sensible price.
