Shares of Berry Plastics (BERY) rose 13 percent in 2015 and the company should stay hot in the coming year due to its new Versalite line of cups, said Ari Sass, portfolio manager for M.D. Sass Funds. 'We think Dunkin’ Donuts (DNKN) is going to roll that out in 2016 nationally, 7-Eleven nationally,' said Sass. 'And we think this is a huge opportunity for them, potentially $100 million of EBITDA to Berry Plastics.' Sass added that the company is also very cheap relative to its free cash flow generation, and will also benefit greatly from lower oil prices reducing its input costs. He is also positive on Gaming & Leisure Properties (GLPI), down 25 percent in the second half of 2015, saying the casino REIT is being overly punished as a result of its purchase of Pinnacle Entertainment’s (PNK) real estate assets. Sass said traders are concerned about a large issuance of new shares hitting the market in the wake of that deal. 'They have the potential to acquire MGM’s real estate assets and other gaming properties, not the operations,' said Sass. TheStreet's Gregg Greenberg has details from New York.
