GLENSIDE, Pa. ( TheStreet) -- Health insurance stock investors reacted rather apathetically Monday to yet another effort by President Barack Obama to push through his health care reform plans. Obama once again on Monday reprimanded health care insurers for their latest premium hikes, but with what seemed like a more forceful tone. None of this presented investors with new information that they could react to. "I think that investors have political fatigue here," BMO analyst Dave Shove said. According to Shove, all the known information has already been factored into the market and the health-insurance stocks. Aetna ( AET) stock has edged 0.3% lower to $31.30, and WellPoint ( WLP) has inched 0.4% lower to $62. Cigna ( CI) is trading at $34.70, down 0.3%. Humana ( HUM) has edged lower to $48, down 0.4%. Other stocks that have moved lower, but not by much, include HealthSpring ( HS), which is down 0.7% at $18.60. The group of health-insurance stocks that moved somewhat more than the others have very little in common, thus one for their behavior Monday may have to do with the many conferences held by the health insurance industry each year. "Maybe some of these companies are speaking at a conference and said something," Shove speculated.
UnitedHealth ( UNH) has fallen 1.9% to $33.10, while Health Net ( HNT) has tumbled 1.8% to $24.10. Coventry Health Care ( CVH) has fallen 1.4% to $24.10, while Molina ( MOH) has risen 1.2% to $23.10. In other insurance news, MetLife ( MET) and American International Group ( AIG) both made noteworthy advances after news about AIG's agreement to sell its overseas life insurance unit to MetLife for roughly $15.5 billion broke. MetLife stock has jumped 4.1% to $40.50, and AIG has popped by 3.6% to $29.10. -- Reported by Andrea Tse in New York Follow TheStreet.com on Twitter and become a fan on Facebook.
