Oscar Health's raised 2026 guidance changes nothing fundamentally, so its 18%+ premarket jump is unlikely to hold. Operating earnings guidance rose to $500-700M from $250-450M, but Oscar had already booked $704M in Q1 alone, more than the new top end, with Q3 and Q4 seasonally bringing losses. 2027 could be challenging as management targets a 5% margin, and the stock looks fairly valued around $34. x.com x.comÂ
