Should You Buy UNH Stock Because Its Cash Runs Ahead Of Its Profit?

UnitedHealth (UNH) has spent the past year repairing margins rather than chasing growth. The shares rebounded well ahead of any actual margin recovery: up about 38% over the past six months, though down about 6% over the past three, and still behind the S&P 500 over the past twelve months, 12.2% for the stock against 18.6% for the index. What argues for owning them now shows up in cash running ahead of reported profit.
