Big 5 Sporting Goods's (BGFV) turnaround set in motion in the summer of 2011 appears to be taking hold, Barron's says. The company is upgrading its merchandise mix to attract customers and boost sales and profits. Big 5 trades for 11.9x estimated 2013 EPS, well below Dick's Sporting Goods (DKS) and Hibbett Sports (HIBB), at 18.4x and 19.6x, respectively. Piper Jaffray's Sean Naughton thinks the shares could command 15x his 2013 estimate of 80c a share in the next year, implying a price target of $12. Big 5 also is revamping its digital marketing strategy which could give a nice lift to its business and share price.
