Urban Outfitters (URBN) shares slipped after the retailer offered cautious guidance for the fourth quarter.

Campbell Soup (CPB) lowered its guidance after a weak quarterly report. Chief Executive Denise Morrison said she was "disappointed."

Home Depot (HD)reported significant growth in profit, revenue and same-store sales, and raised guidance for the year.
