Why would you feel sorry for those that sold? They sure as hell would not feel sorry for you...lol
And I got good news for you, plenty of people have been selling and it's still going up. The selling along the way mixed with heavy buying volume has sustained the run. This is a great thing as it builds higher levels of support for any correction. It also shows that there are plenty of buyers waiting to pick it back up once any selling pressure subsides.
Also we've seen the MM"s soaking up any shares sold while the ask side remains very thin and easy to move. That tells me that the MM's are either filling orders on the bid or they holding for a move up to offload those shares at a much higher price.
All in all it's been a great week and hopefully we continue tomorrow!
