RE:"100k shares in one go..." THERE'S MONEY TO BE MADE HERE. The public float (total shares minus those owned by key shareholders) is roughly 100 million shares and the average daily trading volume over the past 2 weeks has been about 500,000 shares when one includes all the Canadian exchanges (not just Toronto). That suggests the entire public float turns over in about 40 weeks (40 * 2.5 million shares per week). Of course, there are lots of investors who are simply "buy and hold" types (I'm one of them). And lots of investors who have what they consider a "core" position and a "trading" position - so the "true" public float (shares that get traded) is way less than 100 million shares and it is very actively traded. The 100K pro trader sellers make money and they make it from those people who are actively in and out. They don't make it from the buy and hold types - but they do indirectly do some longer term damage which affects the company and all of us.
