Basically all the shares a company has issued make up the outstanding shares. The shares owned by the public make up the float. Float basically equals shares outstanding minus shares owned by the CEO or company insiders. So you aren't actually buying shares from the company since the float is all publicly traded.
Having the float locked creates a situation where the MM's have to play games to free up shares. They do whats called a "shake" where they will take the price up and then sell short and drop the price quickly to induce selling...from those weak hands we talk about. That's how they free up shares.
Now, if the float is locked up (like we have here) and no one is selling, the MM's are forced to take the price up until they find sellers. This is where it gets interesting because us longs here know what we have and are not giving up any shares for a long while! So you can see why the churning here (exchanging shares from weak hands to strong hands) is so important before news.
This idea, combined with solid fundamentals, excellent chart setup and every other reason known to man is what makes this stock so appealing imo. Hope this clears it up for ya.
