Since you have to borrow the stock, someone has to loan it to you. Typically, your broker would loan you the stock. SCOX is not widely held and there aren't many shares outstanding, so it is known as a hard to borrow stock, making it very hard to short. I write software for a stock trading company and SCOX is on our list of stocks we can't short.
