Yep, the harder shares are for them to locate the more expensive the costs to those shorting. I remember reading about another Bio that one brokerage firm was paying a long with big holdings up to 42% per day interest to borrow his shares. It must be getting increasingly expensive to be short CTIX, legal or naked. Want to make things even more difficult for them? Get your shares in certificate form. (Brokerage firms do not like this at all and some are now charging big fees while others are claiming your shares will not be welcomed back.) GO CTIX!!!
