Shares of Minnetonka, Minn.-based UnitedHealth Group reached a 52-week high of $200.8 Sept. 13, according to a Nasdaq report.
The performance likely reflects UnitedHealth's plans to acquire Chilean insurance and clinic operator Banmedica SA and Washington, D.C.-based The Advisory Board's healthcare division.
The deals reflect UnitedHealth's diversification from its core health insurance business, which is highly regulated, to less regulated health service lines, Nasdaq reports.
