I know nothing about how much buying of a stock it takes to move the price, but I would imagine you'd have to really space out your purchases if you're planning to drop $50 million into a stock. Wouldn't the sudden purchase of so many shares make the share price explode to $6 or higher? I would think you'd have too limit your buys to 200,000 to 300,000 shares a day, tops, to keep the share price down while you carry out purchases. But I've also seen companies announce share buyback plans and never come close to buying as many shares as they pre-announced.
