so until then, its just a regular stock, so it may go up* and down until something definite happens with the movie. you never know, plans change all the time, thats why hsx wouldnt cash it out today just because of some possible news
*(why might it go up? eventually some players who are holding it short may decide they want to use that money for something else. so they cover, and if enough players also cover, then the price goes up. most players are going to hold it for the duration, so dont worry about an occassional upturn)
