In my opinion, this will not make any difference in sales unless it extends past December. Apple is going to sell every phone they can make until then, so having them go to China or not is irrelevant. I am sure this will all be straightened out long before Chinese New Year.
I got an E-Mail from Scottrade with all of the details and they also wrote about it in their blog which gets E-Mailed as well.I wouldn't imagine that people would go crazy for too long considering that after a brief moment of panic, they would login to their account and notice that the value was about what they would expect and that they posess a much larger quantity of shares.
One of the big elements of pricing is supply and demand. The iPad Air "ships within 24 hours" while the 5s still "ships within 2-3 weeks" one big question a company asks is "If I am selling all I can make at a given price, why should I sell for less?"
