Yesterday, the price jumped just over 60%, and the volume that day was only a few thousand shares. In fact, one trade that was made that day was responsible for the entire jump in the price. All of the other trades that day were made at the price of the last trade.
On other days, I've seen trades of a few hundred shares move the price by more than 30%. I knew that if I made market orders to buy the stock, I wouldn't get a good price, so I placed limit orders and waited patiently for someone to be drunk enough or desperate enough to agree to my ridiculously low purchase price. Whoever has been selling me the stock at prices that I liked and in amounts that I liked will have to explain his actions to his family and/or his Board of Directors later. That's his problem, not mine.
I hope this clarifies the situation for you, Dutch. My 10,000-share purchase (two days ago) was a limit order, not a market order. I asked to buy 10k shares at 4.5¢, but when my open buy order filled, the price was 4.1¢ per share. Someone else was willing to sell me 10,000 GERS shares at a price of 4.1¢, and I didn't question his judgement.
I also had an open buy order at 6¢ that filled at 5.1¢ per share two days ago. It may have been the same seller or a different seller. I'm never told those identities, and again, I didn't question the wisdom of selling me some shares at 5.1¢, especially since the price was briefly at 10¢ even the very next day (yesterday).
I do have open sell orders on all of my shares, including the 10,000 shares that I bought two days ago at 4.1¢ each ($410 invested plus the commission). I placed those orders because I expect more double-digit volatility in the near-term, so I want to take advantage of it.
If anyone wants my shares, pay my price. You can have every single share if you pay my price.
