Midday Movers: RIMM, CROX, FL & More

Research In Motion fell after rising more than 50 percent the past month on hopes that the company's next line of smartphones will be a success. But some analysts, including Morgan Stanley, say RIM has dug itself too deep a hole to effectively compete with Apple and Samsung.

Crocs and Foot Locker moved higher after Goldman Sachs began coverage of both companies with a "buy" rating.

Las Vegas Sands gained ground after the company approved a special dividend of $2.75 a share.

Hewlett-Packard slipped after former Autonomy CEO Mike Lynch sending an open letter to the company, utterly rejecting Hewlett's claim of financial impropriety at Autonomy.

TreeHouse Foods rose on news that Conagra was buying Ralcorp for $90 a share. Earlier, analysts had speculated that TreeHouse and Ralcorp should merge and be bought by Conagra.

McMoran Exploration sank for the second-consecutive day after the company said on Monday that development of a key well was taking longer than hoped.
