UnitedHealth Group (UNH +2.08%) operates, let’s say, a vast logistical undertaking. They manage the health of a nation, a task akin to herding cats while simultaneously auditing a bank. Alongside this, they’ve established Optum, a platform for pharmacy benefits, data analysis, and direct patient care. A sensible diversification, one might think. However, the company anticipates losing up to 2.8 million members, a rather significant attrition, due to – shall we say – a necessary recalibration of pricing. It seems raising rates, while logically sound, isn’t always popular. A lesson for all aspiring monopolists.
