Looks like someone wants out of their VOIP portfolio at any price. I noted ENG got dumped a few million yesterday and shortly after presumably the same person dumped down into MNF.
It is pretty obvious that someone wants out of the VOIP sector or simply needs some $$$ and all the buyers have now sensibly run away until he is finished.
It will be back to 10's again soon I suspect.
Never looks good though does it?
