RE:Fidelity increases holdings48.2% of shares are held by "Insiders, (10%+ holders). Any selling essentially opens up to retail holders which is why we have this volatility. Now, that being said "Stink bids" are a very smart move for traders and long term investors alike. For example, with the stock trading at say $1.50 I would enter a buy order at around $1.35 or so. A large sell order will drop the shares 10% in one day. It's done it before. On a day trade the bounce-back could get us back to $1.47 or so. 10K shares is a $1200.00 profit. Nice GLTA
