The Lindy affect applies to survival as much as it does to upside. If a business has been the same way for 30 years, it's much more likely to survive another 30 than a new company, but those 30 years will likely be similar to the first. Not all parts of the economy have such a fast up and down curve, so the 30-year business might be an appealing investment or not. Huge delta might be for some investors, but Lindy effect durability is very desirable to others.
