Closing Bell: Humana Falls on Sales Risk; U.S. Stocks Waver on Split Fed

Stocks wavered after the Federal Reserve's September meeting minutes showed a "reasonable argument" for both an interest rate hike and no change at all. The Fed kept rates unchanged at that meeting, though there were three dissenters who voted for a hike. Fed doves pushed for a cautious approach as raising rates was easier than reducing them. Dissenters said history shows waiting too long could lead to recession. A December increase has a 60% chance. Humana (HUM) - Get Report fell after warning of a potential hit to future sales after a negative rating in a measure of Medicare quality. Membership at its top insurance offerings rated four stars or higher fell 37% from a year earlier. Advanced Micro Devices (AMD) - Get Report climbed after Credit Suisse upgraded to NEUTRAL. The firm said AMD has near-term momentum and guidance appears conservative.
