DreamWorks Animation SKG, maker of the “Shrek” films, rose the most since June after an analyst upgraded the stock, citing the November film “Rise of the Guardians,” a boost in production to at least three new domestic films a year and higher TV profit.

DreamWorks, based in Glendale, Calif., gained 3.8 percent to $18.38 at the close in New York. Tony Wible, an analyst at Philadelphia-based Janney Montgomery Scott, raised his rating to neutral from sell. The rating means Janney views the stock as fairly valued and likely to perform in line with comparable companies.
