On E-Trade it is partially marginable from $2.01 to$3 (25%) and then increasing so above that. $2.00 and below it is not marginable.
By close tomorrow all the margin sells should be over with. They worked real hard to keep it under $2 on Monday. Yesterday was heading for $2 until the OED dump. Same with today.
I'd expect one final dump heavy and then it will recover, today or tomorrow. I doubt many are really expecting an LC mention this weekend, but Friday will show it if they are....personally I hope not because it will drop hard if that expectation is not met.
