sure to adjust. If it has an n/a, the attached starbonds won't adjust.
Almost every movie that is going to report BO does so in its first week of release. You can either make the assumption that it will continue to not report box office to ERC (which is the norm) and the starbond won't adjust, or take a gamble that the movie will at some point report to ERC and the starbond will adjust.
It has been known for movies to not report BO to ERC after its first weekend of release, and do so in some later week, catching traders by surprise. However, these instances are pretty rare.
One way to manage these risks is to make a list of the movies in release that have not reported BO, and then check each Monday evening, after HSX updates moviestock pages for the weekend's box office.
