William Blair analyst Ryan Daniels attributes the "fairly lackluster" stock performance of Tivity Health (TVTY) to continued worries regarding UnitedHealth's (UNH) decision to insource more senior fitness plans to its own proprietary offering. Still, United will work with Tivity's SilverSneakers program in 28 states for individuals and will offer SilverSneakers to Medicare Advantage group members in all 50 states, Daniels tells investors in a research note. As open enrollment begins for the 2019 Medicare Advantage season, the analyst believes it also is an "opportune time to take a fresh look at Tivity Health." He views the stock's current risk/reward as attractive and keeps an Outperform rating on the name.

Deutsche Bank analyst George Hill raised the firm's price target on UnitedHealth to $562 from $545 and keeps a Buy rating on the shares. The company reported a Q1 earnings beat with many moving pieces caused by the cyberattack on Change Healthcare, which left earnings quality and guidance up to investor interpretation, the analyst tells investors in a research note. The firm sees the full impact of the hack, as well as conservatism around cost trend and utilization would impact UnitedHealth earnings by only 2% for the full year.

RBC Capital analyst Ben Hendrix lowered the firm's price target on UnitedHealth to $555 from $596 but keeps an Outperform rating on the shares. The company reported a "better than feared" Q1, but the debate over utilization trends is expected to persist through the first half as excess reserves skew the medical care ratio picture, the analyst tells investors in a research note. RBC also notes that its added caution reflects UnitedHealth's "reduced claims visibility".
