Portfolio Manager David Peltier highlights Ballantyne Strong (BTN) as one of his top stocks under $10 for 2015. The movie theater services provider lagged the broader market in 2014, but Peltier finds value in the stock, which is trading below tangible book value. Tangible book value can be calculated from the balance sheet and is equal to common shareholder equity, less goodwill and other intangible assets. When a company like Ballantyne is profitable, tangible book value should serve as a floor for the stock price. The core business is growing and Peltier believes the stock can trade up toward $6 in the new year.
