CharlieB..... I don't know how long you've been trading but I would caution you about liquidating now while taking a big hit unless you need a big tax write-off. Players who have a lot of money to throw around and investment groups have the power, the financial power to create situations that literally scare other investors out of their shares, then they come in and scoop up everything at a huge discount. Consider that.
There's a very good possibility here that this is what's happening especially if there's no catalyst or anti catalyst at play. Crazy as it may sound you may want to consider doing what the fear mongers are doing. Getting ready to come in and scoop up a ton I've shares at a fabulous price.
This is just food for thought from a friendly Vulcan so take it as you will and do as you must. Personally I want you to make a boat load, I mean a disgustingly huge buttload of money.
Spock ... Did it again, misplaced my keys to my shuttle. And I hate asking mr. Scott for a jump. He gets so freaking sanctimonious.
