Dear UnitedHealth Stock Fans, Mark Your Calendars for October 13

Healthcare and care services company UnitedHealth Group (UNH) will report its third-quarter results on Oct. 13, before the market opens. Ahead of the results, investors are looking to see whether the company can build on the robust results it reported in Q2, especially improvements in the medical cost ratio. Before announcing Q3 results, UnitedHealth is scaling back its Medicare Advantage business for next year, discontinuing plans covering about 390,000 members. The move, amid high medical costs, aims to further boost profitability.

Let's look into UNH a bit more deeply.
