Led by a massive, April record opening for Fast and Furious, the box office rose 90% for the top 12 films according to BoxOfficeMojo. YTD now up over 12%. Look for more upside this month for RGC, CNK, and NCMI as comps remain easy. But beware tougher comps starting in May against a very good summer 2008 season that had many blockbusters plus the #2 all-time North American box office of greater than $500 million for The Dark Knight. In other words, if the theater stocks take another leg up, take profits.
