Warren Buffett and the Interpretation of Financial Statements: The Search for the Company with a Durable Competitive Advantage

by Mary Buffett

While many analysts argue that the higher the return on assets the better, Warren has discovered that really high returns on assets may indicate vulnerability in the durability of the company’s competitive advantage. Raising $43 billion to take on Coca-Cola is an impossible task—it’s not going to happen. But raising $1.7 billion to take on Moody’s is within the realm of possibility. While Moody’s underlying economics is far superior to Coca-Cola’s, the durability of Moody’s competitive advantage is far weaker because of the lower cost of entry into its business. The lesson here is that sometimes more can actually mean less over the long-term.
