Take a look at some of Tuesday's morning movers:
Home Depot - The home improvement retailer earned $1.01 per share for the second quarter, four cents above estimates, though revenue was slightly short of consensus. Home Depot also raised its yearly earnings per share forecast to $2.95, three cents above current analyst estimates of $2.92.
Michael Kors - The luxury goods maker earned $0.34 per share for its first quarter, well above estimates of $0.20, while revenue also beat consensus forecasts by a wide margin. The company also sees current quarter earnings coming in above Street estimates.
Estee Lauder - The company earned $0.17 per share, excluding certain items, for its fourth quarter, one cent above estimates. However, its forecast for fiscal 2013 is short of analysts' estimates, with Estee Lauder expressing caution about softness in global markets.
Dick's Sporting Goods - The sporting goods retailer earned $0.65 per share for the second quarter, excluding certain items, one cent above estimates.
Groupon - The daily deals provider earned $0.08 per share for the second quarter, five cents above estimates. But its revenue was short of consensus, and its current quarter revenue projection is on the cautious side.
Coinstar - President and Chief Operating Officer Gregg Kaplan is leaving the company. Kaplan was the founder of Coinstar’s Redbox video rental unit, and is leaving to pursue new opportunities.
Agrium - The Wall Street Journal reports that hedge fund Jana Partners has taken a little less than 5 percent stake in the Canadian fertilizer producer.
Pfizer - Pfizer is paying $250 million to AstraZeneca for exclusive global rights to an over the counter version of AstraZeneca’s best-selling heartburn drug Nexium. Pfizer cut its full-year profit forecast to reflect the deal, while AstraZeneca raised its outlook.
Micron Technology - A group of bondholders in bankrupt Elpida Memory is putting pressure on Micron to increase its takeover bid. The bondholders have proposed an alternative restructuring plan for the chipmaker, offering to lend it $383 million to help it restructure.
Wal-Mart Stores - The retailer has received Chinese government approval to raise its stake in Chinese e-commerce company Yihaodian to 51 percent, becoming the controlling shareholder. The acquisition had been subject to a lengthy antitrust review before finally being approved.
Qualcomm - The semiconductor maker is said to be providing chips for new devices from Dell and Samsung that run on Microsoft’s Windows RT operating system, according to Reuters. Windows RT is the version of Windows 8 that runs on devices such as tablet computers.
Viacom - A court has ruled that Viacom must pay $300 million in bonuses to shareholders in videogame maker Harmonix, even though it sold the Rock Band maker back in 2010. The decision stems from the structure of its original deal to buy Harmonix.
Select Comfort - The mattress maker's shares are rated "overweight" in new coverage at Barclays.
