I’ve been looking into long-term stock investments lately and keep coming back to the idea of a company’s moat. It seems crucial, but I’m curious how others actually assess its sustainability. What specific signs do you look for to tell if an advantage is durable or just temporary? For example, beyond brand power or patents, how do you gauge things like network effects or cost advantages holding up over a decade? I’d love to hear what frameworks or real-world examples have helped you make these judgments.
