If you have deep pockets it isn't hard to manipulate SDL...
esp the past week when fear of cap raising and permits being revoked was doing the rounds (esp on this forum)... and dont think the funds/hedgies don't monitor HC... because they do
sentiment can be powerful... esp fear
I'd be guessing a fair few holders sold out recently only to now want to buy back (hopefully at a lower price)
Afferro news didn't harm SDL either
