Er, they'd already "sold" on a fixed price subscription based offering to other investors. It wasn't announced as an upcoming sale but rather as an announcement of an already executed divestiture at a fixed price. So this has all been, beyond that point (around $11.45) an exercise in FUD plus the effect of cascading stop loss orders adding to the above FUD.
Call it a buying opportunity, grab as much as is reasonable to your strategy, and say thank you for the easy profits, as anything under $11 is a no brainer buy. Not a STRONG buy anymore, it would have had to drop far further, but a buy is almost as good even buying on margin. Note that NONE of this effected Citadel as they'd ALREADY sold their shares through the subscription offering.
post facts not rumors. how do you know those were citadel shares? they have burned investors every time they could as far as etfc goes!!looking for low tens a coming !!! the best thing for etfc is getting rid of citadel for good!!!IMHO they suck
