A monopoly may arise from a patent or copyright, or from a trade secret, a moat, or — as maybe you are thinking about here — a firm with a market so narrow that others can’t of won’t compete. I don’t think I have any monopolies in my portfolio mainly b/c I don’t have any public utilities (not counting TMUS as a utility the way T’s subsidies were back in the day.) And some utilities — Hello Thames Water! — would best be sold short. Maybe I missed something above: I do have a few shares of MELI, having had them in the past and sold at a gain. And NU has done well for me though I have only a few shares I bought on 11 April 2023.
