Central Garden & Pet Co. (CENTA) had the biggest drop since November, losing 33 percent to $4.67. The seller of Pennington grass seed and Sevin bug killer said it's ``less optimistic'' it will report higher earnings than last year because it has been unable to offset rising grain costs with price increases.
Diodes Inc. (DIOD) rose 7.3 percent, the most since April 16, to $29.50. The maker of electronic components used in computers and DVD players said second-quarter revenue will be higher than previously forecast because of contributions from Zetex Plc, which it bought June 9.
Hooker Furniture Corp. (HOFT) had the steepest loss in a year, dropping 14 percent to $17.51. The furniture retailer predicted ``sluggish'' business for the rest of 2008 as the weakening U.S. economy reduces consumer spending.

Rex Energy Corp. (REXX) gained 8.2 percent to $29.27, the highest since shares began trading a year ago. The oil and gas company was recommended by CNBC ``Mad Money'' host Jim Cramer, who called the company a ``wildcatter'' because of its potential to find new oil in the Marcellus Shale region.
