The Acquisition being pumped here is Vega Biofuels purchase of BioChar (which you can read about on Vega Biofuels website under news. The price increase today wasn't based on a run up of an acquisition, rather it was a transfer of shares that was previously agreed upon (see level 2 trading). Vega is still young and a long way to go before they are legit players. I do recommend buying but wait until the price drops back down and stock up. That's what I do and I sell part of it on days like today where I can make some money to buy other stocks. Bottom line, don't believe these pumpers. They really have no influence on the price (as much as they'd like to believe they do).
