Despite the claim of record of public shorting, I think the majority is long. So it is hard to say which is the 'herd'.
This kind bull run I've only seen only twice, one is the bubble era, and one is after Iraq war started. So if you think this rare event is 'for granted', well, good luck.
High indeed is not a good reason to short, that's why I don't worry about RIMM and GOOG.
So far the bulls has played a good poker game, but there are still cards to draw and I can wait for a few more days.
