Dollar General Corp. (DG US) sank 9.3 percent, the second biggest drop in the Russell 1000 Index, to $31.81. The largest U.S. dollar-store chain reported first-quarter profit that missed analysts’ estimates, hurt by rising gasoline prices.

SkyPeople Fruit Juice Inc. (SPU US) plunged 18 percent to $2.08, the lowest price since October 2008.
