Insight: When looking at a company, what type of building is it?
Large companies (with competitive advantages) can be pyramids or skyscrapers. Both are large and have commanding presences. Both have high returns.
Pyramids are strong — you can’t knock them over. Skyscrapers are tall and strong, but they can be knocked over much easier. For a pyramid to be destroyed, it must start at the top, and slowly erode over time. After a while, only the foundation will be left. With a skyscraper, the foundation can be destroyed first, and the rest of the company will go with it.
Wal-Mart is a pyramid. Google is a skyscraper (for now — it seems that Larry & Sergey are in the process of building the foundation up). Berkshire Hathaway is a pyramid. Newspapers were pyramids — however, over the last two decades, they have been slowly chipped away starting from the top. Now, the foundation is about all that’s left.
Skyscrapers can be turned into pyramids over time. But that requires great management and somewhat favorable circumstances. The time it took to build a company doesn’t necessarily tell you what type of building it is.
You can combine this analogy with Buffett’s moat analogy. Moats are barriers to entry — the wider the moat, the harder it is for competitors and disruptive technology to affect the company. But if the moat can be crossed, you’d much rather have a pyramid than a skyscraper.
