stocks to watch

Sonic Corporation (NASDAQ:SONC): Though the company’s same-store sales continue to rise, and operating costs are declining, its stock prices are falling. Sonic Corporation (NASDAQ:SONC) reported a 12 percent increase in its first quarter earnings, but shares plunged 3.07 percent to $10.74 in early market trading. Analysts and investors are concerned about  the company’s long-term model. Barclays analyst, Jeff Bernstein, said that comparisons with prior year quarters are getting tougher, and the fast food industry is getting increasingly competitive.

Coinstar, Inc. (NASDAQ:CSTR): The Redbox DVD-rental kiosks operator said Thursday that its fourth-quarter earnings could easily beat forecasts. The company also said that its CFO, Scott Di Valerio, will succeed the outgoing CEO, Paul Davis, in three months. However, investors are skeptical about Coinstar’s unease over earnings drivers and strategy uncertainty.

Accuray Incorporated (NASDAQ:ARAY): The company announced that it will lay off 13 percent of its total workforce under a restructuring plan. The producer of CyberKnife, a robotic system to treat solid tumors, has also lowered its second quarter as well as full year outlook for 2013. Shares tumbled 25.52 percent to $5.05 in premarket trading.

Progress Software Corporation (NASDAQ:PRGS): The company sold off many of its product lines. As a result fourth quarter profits surged but revenues declined. Shares were up 4.40 percent to $2889 in early market trading.

InterMune, Inc. (NASDAQ:ITMN): The biotherapeutics company said its revenues for FY2013 will largely depend on the timing of the launch of its medicine for a rare lung disease in European countries. InterMune shares were down 0.57 percent to $10.40 in early trading.

Rovi Corporation (NASDAQ:ROVI): The entertainment data and technology company has raised its full-year earnings outlook. Rovi is also selling its entertainment store business to focus on its core business of technology and services. Shares surged 4.54 percent to $16.58.
