The Might (and Myths) of Economic Moats

"Buffalo, New York was able to have more reliable energy than almost anywhere in the world at that time because of the power plant with Niagara Falls.

If you were a business building in Buffalo, New York in around 1900, you had cost advantages, both on the energy side and then also on the distribution side." That was a real economic moat. But as Lou Whiteman points out, "the thing is, it didn't work out over time for Buffalo."

The hosts (with John Quass as the moat advocate and Lou Whiteman as the skeptic) explore whether "economic moats" are a useful investing framework or a backward-looking illusion.

What a Moat Actually Is

John Quass lays out the classic framework from Pat Dorsey's The Little Book That Builds Wealth, which identifies four types of moats: intangible assets (brands), switching costs, network effects, and cost advantages.

For many buy-and-hold investors out there just getting started, knowing how to understand businesses better is one of the first skills to develop. One term that the financial media world has developed for business strengths is economic moat: that “it factor” that keeps its competitors from posing a real threat to its business. Lou, Jon, and Tyler break down what makes a good economic moat, what are some of the “false flags” in moat analysis, and examples of companies with both wide and narrow moats.
