I agree that there could very well be a sell-off, but the only ones taking profits would be the day traders.
The recent movements would have to be the institutional buyers coming in quickly and selling out quickly in order to take short term profits. The day traders are probably making money too, but they come and go.
The BS that you here about news affecting the markets is mostly horsepoop. All I see is short term profit taking behavior. It will probably continue for a while.
