A product or service becomes commoditized when it's so standardized and interchangeable that customers see little to no difference between offerings from various suppliers. Think of basic table salt, wheat, or crude oil. When you buy these, do you agonize over the brand? Probably not. You just buy the cheapest one available. This is the essence of commoditization. For a business, this is a dangerous state of affairs. Once customers make decisions based solely on price, the company loses its pricing power—the ability to charge more without losing business. This triggers a “race to the bottom” on price, squeezing profit margins and making it incredibly difficult to earn attractive returns. For a value investor, a business selling a commoditized product is often a red flag, as it suggests the absence of a durable competitive advantage, or economic moat, to protect its long-term profitability.
Products aren't born commoditized; they become that way over time. A once-innovative product can slowly lose its uniqueness as competitors catch up, patents expire, and the technology behind it becomes widespread.
Several factors can strip a product of its special status:
The philosophy of value investing, championed by figures like Warren Buffett, is built on finding wonderful companies at fair prices. Commoditization is the enemy of “wonderful.”
A strong economic moat protects a company's profits from invaders (competitors), much like a moat around a castle. This moat can be a strong brand, unique technology, or high customer switching costs. Commoditization is like draining the moat and lowering the drawbridge. When price is the only thing that matters, any competitor can attack your castle by simply offering a lower price. A business in this position struggles to generate a high return on invested capital (ROIC) because it has no way to defend its profitability.
When a company loses its pricing power, its ability to maintain healthy profit margins is severely compromised. In a commoditized market, the only way to win business is to be the cheapest. This leads to brutal price wars where companies slash prices to gain market share, often to levels that are barely profitable. This continuous downward pressure on margins makes it nearly impossible for a company to generate the kind of consistent, growing cash flow that long-term investors cherish.
As an investor, you can spot a business heading toward the commoditization cliff by looking for these red flags:
While the path to commoditization is well-trodden, it's not always a one-way street. Shrewd companies can fight back and “de-commoditize” their offerings.
