Just as an experiment I have bought 1000 UNH for my managed account at 24.77
I did a DCF analysis and my margin of safety is around 48% supposedly. I know Warren Buffet owns this. And finally, the chart says this has come around for a new swing.
So I'm just going to forget about it for 6 months and see if it pans out. In general, it looks like a piece of crap company. Value? yes. But the story is horrible, as all health insurance companies are these days.
