A multiple (also known as a 'valuation multiple' or 'trading multiple') is a financial ratio that investors use to value a company. Think of it as a quick and easy shorthand to gauge a company's worth by comparing one financial metric to another. For example, when you buy a house, you might compare its price to its square footage to see if you're getting a good deal relative to other houses in the neighborhood. In the same way, an investment multiple compares a company's price (like its Share Price or its total Enterprise Value) to a key business metric (like its earnings, sales, or book value). The most famous of these is the Price-to-Earnings Ratio (P/E), which tells you how much you're paying for every dollar of a company's profit. These ratios are the bedrock of relative valuation, allowing investors to compare a company's price tag against its peers, its own history, or the broader market, helping to quickly spot what might be cheap or expensive.
For a value investor, the goal is simple: buy businesses for significantly less than their Intrinsic Value. Multiples are one of the most powerful first-glance tools for this treasure hunt. A low multiple can be a bright neon sign pointing toward a potentially undervalued company, flagging it for a deeper investigation. Conversely, an eye-wateringly high multiple can serve as a warning of speculative fever or a “story stock” whose price has become dangerously detached from its underlying business reality. The legendary value investor Benjamin Graham warned against overpaying, no matter how wonderful the company. Multiples provide the initial, crucial context for “price.” They help you frame the question: “Am I paying a sensible price for this business's performance?” By grounding your analysis in these simple ratios, you can avoid getting swept up in market hype and stay focused on finding genuine bargains. They are the starting point, not the destination, of a thorough Valuation.
Multiples come in several flavors, each telling a slightly different story. They generally fall into two main categories: those based on the stock price and those based on the company's total enterprise value.
These are the most common multiples you'll see quoted in the financial press. They compare the company's stock price to a “per share” metric.
These multiples are often preferred by professional analysts because they give a more complete picture of a company's total value, as if you were buying the whole company outright—debt included. Enterprise Value (EV) is calculated as Market Capitalization + Total Debt - Cash.
Relying on multiples without critical thinking is a classic rookie mistake. They are a fantastic starting point, but a terrible finishing line. Always be aware of their limitations.
Think of multiples as a financial thermometer. They give you a quick reading on whether a stock's price is hot, cold, or just right relative to its peers and its own history. They are an indispensable tool for screening for ideas and framing your analysis. However, a thermometer can't diagnose the illness. For that, you need to be a doctor—to dig into the company’s annual reports, understand its business model, assess its management, and confirm its competitive standing. A multiple tells you the price of the stock; a deep business analysis tells you its value. The secret to successful Value Investing is buying when there is a beautiful, gaping chasm between the two.
