I've been selling as well.
Nice broad rally; Faber and Jeremy Grantham are talking about SPX 1000-1100 by the end of the year. On the other hand, plenty of signs of excessive speculation. Insiders are very bearish, OEX P/C is a "sell". I hope to see significantly lower ROBO P/C tomorrow. Folks on the boards are still rather cautious IMO, but there are more posts like this (borrowed from aj's board):
"To keep it simple, throw the charts away, the Larger that Large Boys made decision to pump Dow to 9000+,10000+_ect. They are pumping/pumping and will not fail because they can print money faster than any sell button".
