thats when you will see heavier volume, they cant dump now and then wait till when they are ready to replace it, you will see the moves coming on the 22nd. Until then there will be positioning for this sort of thing by shorts and longs, Between now and then you will extreme volatility in this stock. I have to believe that the volume today does show some funds and institutions geting in and out of cien today, no doubt funds got out and others got in, all in all i think the stock performed according to expectations. I am long 30000 from yesterday at 6.23 i am underwater a bit but do believe the stock will go higher.
furthermore, any rally attemp will be shot down by these fund manager as they take the oppotunities to unload the stock. not to mention hedge fund will short it down to minimum and pick the money lying down in front of them.
