Early Retiree Reality (ERR) recently published a thought provoking article titled My Duopoly and Oligopoly Shopping List on Seeking Alpha. The premise is essentially that duopolies and oligopolies provide wider moats which results in greater profitability. I would encourage you to read it. This idea is similar to one I’ve been working on with my Speculative Pillars series on Cord cutting, Transaction Processing and to a lesser degree Regional Banks. Although neatly packaged, I failed to make the leap into the –opoly world.
