I don`t think you should call it manipulation. I think you should call it trading.
The question traders and investors are asking: How do you price a stock with:
Tremedous upside: AMD. a possible patent win, potential licensing wins etc
vs
Tremedous Downside: Swartz/Lincoln, a possible patent loss, potential of no more licensing
Its a penny stock. Roll the dice and hope you don`t crap out.
