NEW YORK - Stocks were mixed but little changed Wednesday as investors pored over the latest batch of earnings reports. Luxury goods maker Coach slumped after reporting a lower profit. IBM fell on a revenue shortfall.

The S&P 500 rose 1.05 to 1,844.85. The Dow Jones industrial average fell 41.10 to 16,373.34. The Nasdaq gained 17.24 to 4,243.00.

Any qualified entrants who correctly predicts every game will share in or be paid 40 annual installments of $25 million or an immediate $500 million payout.

The company says the cuts in its embedded processing unit and in Japan will result in $130 million in annual savings. It also said its fourth-quarter profit nearly doubled to $511 million as restructuring charges fell and revenue ticked up.
