Even if you think google is mispriced and overvalued, this is still the worst idea ever. You can go broke and lose all of your money a lot sooner than the market can become rational.
Anytime EVERYONE is long... and thinks shorting is a good idea... means that in the near future, some shorting opportunity for at least a nice pullback will arise. The disciplined trader with a tight stop loss who can see the entry and get out when/if GOOG resumes its run will do quite well
HILARIOUS reading all these old posts, all you ultra-bulls and the like. Funny stuff! If only you would've listened to me, you would have only had to ride it up $60~ max and then came the plummet.
Google is one of those stocks that always rebounds huge. Big funds loading up. You dont short it. If you want to short consider radio shack or airlines. Never short google, apple, or rimm. Most people lose their shirts.
