The discount chain Ross Stores jumped 6 percent, the best gain in the Standard & Poor's 500 index. The company said stronger sales in March will likely push profits above its previous estimate this quarter.
Rite Aid soared 18 percent after the drugstore chain said higher sales of generic drugs and lower costs helped it post better earnings than analysts had expected.
