Traders on the floor of the New York Stock Exchange.

Progressive –The insurance company's stock was upgraded to "buy" from "neutral" at Citigroup, noting an improvement in Progressive's underwriting spreads.

Kohl's –Kohl's earned $1.13 per share for its second quarter, beating estimates six cents, though revenue was slightly shy of forecasts. Comparable store sales fell more than expected during the quarter, though Kohl's points out that it had positive same-store sales during the month of July.

Wal-Mart –The world's biggest retailer matched estimates with quarterly profit of $1.21 per share, while revenue was slightly above consensus. Wal-Mart cut its full-year forecast, and said performance in its U.S. Walmart and Sam's Club locations were not as good as it would have liked. The lowered forecast is the result of higher employee health care costs and increased investment in the company's online business.
