Dear UnitedHealth Stock Fans, Mark Your Calendars for July 29

After a challenging year for healthcare stocks, all eyes are on UnitedHealth Group (UNH) as it prepares to unveil its second-quarter earnings on July 29. Once a stalwart of defensive investing, UnitedHealth has seen its stock tumble nearly 45% year-to-date, making it one of the worst performers in the S&P 500 Index ($SPX). Although its first-quarter revenues of $109.6 billion showed modest growth, rising medical care ratios and suspended full-year guidance have left investors on edge.

Will UnitedHealth’s upcoming results mark the beginning of a comeback or signal more turbulence ahead? Let’s find out.
