Major health insurance stocks rose across the board Monday, the first day of trading since reports revealed Walmart has discussed an acquisition of Humana.
Shares of Humana jumped 7 percent. Shares of Anthem, UnitedHealth and Medicaid-provider Centene were up 1.4 percent, 3 percent and 0.8 percent, respectively, while shares of Walmart fell 2.2 percent.
Though discussions remain in early stages, sources confirmed to CNBC that Walmart is interested in strengthening its existing relationship with Humana amid a rush of deal speculation in the industry.
