Sirius XM Radio ( SIRI) Company Profile: Sirius XM provides music and talk radio entertainment through satellite transmissions. Current Share Price: $1.71 (Jan. 4) Potential Upside: 13% based on a price target of $1.85 Barrington's Take: The best-performing stock for Barrington carries over into 2011, with the firm noting fundamental improvements for Sirius XM, including trends in auto volumes. "While these gains did not dramatically improve our profitability outlook for 2010 (due primarily to associated subscriber acquisition costs), they should set the stage for further upside in 2011 and beyond," Barrington analysts wrote. "Interest in this story should continue to improve as management continues to deliver on its financial and operational metrics, demonstrating that the substance of the turnaround story is real."
