GOOG would certainly be the last one I would go short on. C since suggested by Running_Man has lost 21%. That was a good short and probably still is ! It was much easier to make 700% on GOOG going long than it will probably ever be to make 25% going short on it...
Remember that you never make more than 100% on a short (and making 50% is already damn good), that you only short weak stocks, that timing is critical as your stop buy must be pretty close to where you enter short otherwise the risk/reward is bad and my suggestion is to read Stan Weinstein's (old) book before making your first short.
Funny enough, the first short I ever made (a long time ago) was on a very bullish stock (like GOOG) which (in my opinion) would never pass its all time high. Of course, it easily did, triggerred my cover stop in some days and left me at a loss so quickly that I could not comprehend why I had been so wrong
