I am not so certain this is a moron or sub-culture

I am not so certain this is a moron or sub-culture trying to cover or hold the price down.  If that is the case, then why are they following these take-downs with some very large buys.  It seems as though each time the 100 share sell orders are processed, they are followed with a large buy order.  This could be a large player manipulating the price to acquire as many shares as possible.
