IINM Its normal for the up and down...
But ya, it fell right after they saw the unimpressive showing...
If they had something truly innovative, i believe it would have climbed right away...
Your belief is totally off..
The stock literally takes a dip the second the phone is announced every single year, and it stays down for a while, it only starts going back up when strong pre-order numbers start surfacing in news reports.
The drop has nothing to do with being "unimpressed" with the release, it has everything to do with "buy the rumor sell the news".
The stock kept on cracking all time highs the last few months solely because of iPhone X rumors, the rumors ended today, and the stock took a breather, that's all.
