Electronic trading is a tricky thing... many set stops that, once taken, sell at market. In a low volume setting such as HPJ it is easy to drive the sell price down when it is being done electronically. If you notice, its climbing back up again. The company is small but it is very visible, especially considering their deal with Sony. I would not listen to people who only point to the fact that the company is in China... that's low-ball, amateur DD. This is a company that is transitioning from development to market. Hold tight and accumulate when you can.
Conference call to who? No one cares. Except the morons stuck in the quicksand here. Institutional ownership in this pig is 2% but the morons here know more that professional investors. Ha! they are company paid hypesters with no clue on investing.
