RE:Market drop on 16K shares, what a joke !It's obvious that this stock on this market is so thinly traded that daily valuations are useless. Manipulation, 40% of daily volume occurs between 3:59 & 4:00 each day. I've given up caring what the price / market cap is. This should be sold based on it's dollar value (NPV). That is the only measure that is verifiable and based on modeling. RIO / others may disagree or negotiate what the NPV should be but fighting over stock price on a manipulated, short selling, thinly traded inefficent stock trading mechanizim makes no sense to me.
