Yes. They'd have done better to start the pump early in the week, I think.
Some probably already did sell because it's so dangerous to hold these pinkies over the weekend!
Most pumps last three days, four at the most, and then the fun's over. The weekend could stall the momo, though, unless there's news, and for once it's good news.
I'm inclined to suspect that this is the final pump before a very large reverse splot.
