UnitedHealth Group shares keep falling, other health insurance stocks follow, as criticism of the industry heats up

Major health insurers have seen their stocks sink along with consumer sentiment since the shooting of Brian Thomson. Now Congress might shake things up even more.

Major insurance stocks including UnitedHealth Group, Cigna Group, and Elevance have fallen in the past five days. The decline has been pronounced since their closing prices last Tuesday, which was one day prior to the killing of UnitedHealthcare CEO Brian Thompson.
