i always find it funny how some people likes to compare stock price movements with annoucements.
the annoucement of japan's apple store is nothing new to stock analysts. just because apple annouces something positive(negative) doesn't mean its stock price should go up(down). stock market and share prices reflect a very complex web of information with a lot of people trying to outdo each other in order to make money. any new piece of information is reflected in the market within seconds. apple's share price is not linearly correlated to any one piece of information.
i imagine the health of the semiconductor or other computer hardware supply industry and tech industry's spending trends will have far, far greater impact on apple's stock price than the ginza apple store opening or, for that matter, "success" of iTMS.
anyway, when i was in japan in mid-Sept., i didn't know that the store hadn't opened yet. i went to ginza looking around but learned that it's not open yet at... the sony store, of all places. the sony store was very cool, a lot of gadgets and i'm sure the apple store will be even better. can't wait for the next time i go back...
though availability of apple was far better in japan than in states. i found some form of mac being sold in practically every electronics store.
