Pattersons placed a target price of 13c in the most recent broker report on 01/05/09. It could be a reason for the sell off? Unless something like Russia starting a war or a JV with a major player occurs, the stock price could remain where it is for a while. Also, large volumes could just mean the day traders are moving in.
