Why the big drop, after announcing they're presenting at the conference next week? I would think that would be good news. Unless this is manipulation so people can load up cheap before the conference. The irrational trading of the stock market can be frustrating at times.
There is no liquidity in the stock. Some #$%$ hole decides to sell 10,000 shares at market and he crushes the price. Thanks a lot. Then others decide they better get out too and before you know it everyone is running for the hills. Buyers will eventually show up but price may be around $4.30 before they do, at least that's where I see a rising trendline that goes back to May of last year
Maybe he or she isn't such an a## hole. Maybe they "feel" that the news won't be so great. 10000 shares is a lot of shares to sell at one time. Confidence is starting to wane. Obviously management hasn't shown too much confidence in the stock and they know more than anyone about what's going on.
