Apple announced before the opening bell that it would pay a quarterly dividend of $2.65 a share, and it will buy back $10 million of its own shares over the next three years. Shares of Apple jumped after the dividend and buyback announcement, remaining just below $600. The Dow Jones Industrial average increased 6.51, or 0.05 percent, to 13,239.13.
