SLW is making a major investment. Mr. Market and other hysterical types tend to over react when deals are made they overwhelm their little minds.
Think of this as an anal expulsive explosion ridding the stockholders of the timid in their ranks. There will be a reboud. If you held on, you tell all your friends what an investment guru you are. If you sell out, you can tell all your friends how Wall Street is being manipulated by evil forces.
