NEW YORK (AP) — CEOs at the biggest companies got a 4.5 percent pay raise last year. That’s almost double the typical American worker’s, and a lot more than investors earned from owning their stocks — a big fat zero. The typical chief executive in the Standard & Poor’s 500 index made $10.8 million, including bonuses, stock awards and other compensation, according to a study by executive data firm Equilar for The Associated Press.
