From someone who has traded from both sides for over 20 yrs, I feel compelled to clarify one thing that is being discussed here. Squeezes are almost impossible for the insiders to pull off on highly liquid stocks like this.
The Squeeze is an insiders play make no mistake about it. As long as the stock you are looking at is trading over a million shares a day, and also has plenty of individual trades, there is nothing to worry about in terms of a squeeze situation.
It is only when the bulk of the shares are in a few hands, that a squeeze takes place. LEND is not likely to be a candidate for anything like that by looking at these aspects of it. Just stay away from shorting stocks either under $10 or with small capitalization, or low volume, and you should be fine.
