after hours changes mean little or nothing to me but SOMETIMES it does reflect the next days price. what i do is put a phony trade (not complete) in my account to see what my BROKER indicated & compare it! in this case they show a 60 cent increase/ rather than the closing price. i'll do it again around 1 hr. before it opens to see if they kept it or what changes they made! almost all of the times (even if the stock shows a big after hour change ) my broker would indicate the bid & ask price around the closing price! wish you luck!
