AutoZone - The auto parts retailer reported fiscal second quarter profit of $4.15 per share, 11 cents above estimates. AutoZone saw a same store sales increase of 8.6% compared to a year earlier, and also saw its profit margins increase.

Office Depot - The office products retailer earned three cents per share, excluding certain items, for the fourth quarter, better than analyst estimates of a breakeven quarter. Results were boosted by lower costs and fewer discounts.

Tenet Healthcare - Tenet earned 10 cents per share, excluding certain items, four cents below estimates, with revenues also falling short.

Domino's Pizza - The company earned 52 cents per share for the fourth quarter, three cents above estimates, but revenues were less than Wall Street consensus. Domestic same store sales were up 6.8 percent for the quarter, but results were impacted by higher commodity costs.

Priceline.com - Priceline reported fourth quarter profit of $5.37 per share, 32 cents above estimates, with revenues also beating consensus. And its current quarter guidance of $3.80 - $3.90 per share exceeds current consensus of $3.72. Priceline’s earnings growth was driven in large part by a rise in international bookings.

Callaway Golf - The company has named Chip Brewer as president and chief executive officer, replacing interim president and CEO Tony Thornley, who had served in that job since last June. Brewer had been chief executive officer of Adams Golf since 2002.

Sina - The China internet services provider is projecting first quarter revenues below current Street estimates.

Cooper Tire - Cooper, whose shares surged almost 14% during the Monday session, could get another boost today as workers in Ohio approved a new contract, ending a 3-month lockout. More than 1,000 workers will return to work under a new 5-year deal that increases wages but allows the company to trim its workforce.

Procter & Gamble - The Dow component's stock has been upgraded to a "buy" rating from "neutral" at Bank of America/Merrill Lynch. The price target was increased to $75 from $69. The firm says it's encouraged by P&G's renewed focus on cost savings.

Rambus - The chipmaker has begun a search for a successor to CEO Harold Hughes, who is planning to retire in April.

Nokia - The maker of mobile phone handsets has been downgraded to "underpeform" from "perform" at Oppenheimer, on concerns about the pace of transitioning to the Windows phone platform.
