The .17 decline has as much "reason" as would any random .17 increase. Stocks go up and go down. Yes, .17 can appear "steep" if you worry about how much money you may have "lost" in one given day. But don't worry. It'll be ok. As for OW opening: given that everyone knows that it is opening, you should not be able to discern any day's movement that is attributable to that fact. Only if the initial opening significantly garners more, or less, per-theater than is "expected" should you perhaps be able to say that share movement was caused by that. But, still, remember that any one given film contributes little proportionally to the bottom line at year's end.
Good numbers. Well ahead of Notebook, and holding on to #10. Comparatively fine per-theater numbers at this stage. Will have crossed $110m sometime today. $510,000 (estimate) -50.4% / $419/ 109,953,000 / 41
