What Makes a Great Moat? Evaluating a Company’s Competitive Advantage

As Warren Buffett often says, the key to successful investing is finding companies with strong economic moats - sustainable competitive advantages that protect them from competitors. But how exactly does an investor quantify the strength and defensiveness of a company's moat? Here are some tips:

First, identify the sources of the moat. The most common types are cost advantages, strong brands, network effects, high switching costs, and intangible assets like patents. Understanding the nature of the moat reveals a lot about its durability. Brands, for example, tend to have high customer loyalty and pricing power.

Next, dig into the financial statements. Metrics like profit margins, return on invested capital, and revenue growth can indicate competitive strengths. Compare these figures over time and against rivals to gauge relative performance. Steady, high returns often signify durability.

Also evaluate the company’s market share and position. Dominant players with stable share in their niches frequently boast the strongest moats. Customer surveys can also provide color around brand power and loyalty.

Analyze the industry landscape as well. Factors like barriers to entry, supplier/buyer relationships, and the pace of disruption all affect the staying power of competitive edges. Consider how trends could alter the competitive environment.

Lastly, assess management’s role. Great leaders not only build moats; they continually reinvest to widen them. Study the strategic vision and track record of executives.

While tricky to quantify precisely, moats reveal themselves through sustained exceptional performance. No single metric perfectly captures competitive advantage. Instead, develop a holistic understanding by piecing together various financial, operational, and qualitative clues. With a robust analytical toolkit, investors can better appraise the durability of a company’s economic moat.
