I'm no expert, but all stocks are shorted, including ITRO. Looking at the site you'll see how many shares are available to borrow, at what rate, on those specific dates. One could open an account with Interactive Brokers, and borrow shares of ITRO to short. It's a great way to make a few bucks, and keep the PPS in a trading rage for accumulation. I've shorted stock, but never pink sheet stocks. If I had the time, I'd follow the short availability in relation to hits in price. I assume some of our price retraction is normal selling, and some shorting. It's not unusual for someone with a lot of shares to lend them out via these brokerages for shorting and make a few bucks in interest with no risk. When the stock becomes marginable, anyone who buys them with margin, automatically agree to lend them out interest free. Again, no expert, but it will be fascinating to watch all of this unfold.
