MatrixMan, I can't speak to the TA in a situation like this, but I've been buying ALVR with both hands under the rubric of "buy when the blood is running in the streets". Just picked up some more at 11.95.
I see no company specific news to underline this drop. As far as I can tell, it's all about the new Israeli policy and reactions to it. Of course, you may want to dismiss my comments under the heading "misery loves company" <g>
