The U.S. managed care sector has had a rough year. Medical costs jumped, reimbursement outlooks were cut, and the country’s largest private insurer, UnitedHealth Group (UNH), found itself at the center of a serious credibility problem. By late January 2026, UNH had dropped about 46% over the prior year, erased roughly $60 billion in market value in a single day, and pulled its full‑year guidance after a weak Q4 and restructuring charges.
The stock then spent months trying to find a bottom. By late March, UNH was still down 18% year-to-date, trading well below key moving averages, while analysts cut Q1 estimates as high medical costs kept weighing on sentiment.
