There is no quiet period. They just must adhere to Reg FD which basically says that if non-public information becomes public accidentally, they have 24 hours to go public. That doesn't apply here. My guess is that with this truly being old news and earnings a week away, they won't respond since they have a history of being quiet.
The management's extreme secrecy is helping shorts. This onslaught will eventually lead smart people in the company to leave and this rumor will become a self-fulling prophecy. Cook needs to wake up to the reality.
You need to make up your mind of what the news said. Did LG say LCD panel was cut by decrease in iphone 5 or just the media or korean analyst said? If you read it carefully, you will realize it is just another rumor. Wake up man. Korean media and korean analyst tried to beat down apple. Dont get trapped. Fool.
They don't need to bother themselves with rumors.
I don't want a management team at Apple managing the street. I want them building great products and not distracting themselves with all that noise. It's a full time job once you get involved battling rumors.
