Just remember when a big guy says SELL, he previously sold higher awaiting others to sell the price down.  When it's down he buys than make a public declaration, BUY. He is than hoping every one else buys the price back up so he can sell again.   This is a pattern the big fund mangers love while stocks are flat lined.

That said, know why you bought the stock, and unless you are a trader hold on tight to your shares. When NOT has proven their worth a large mining company is going to buy it at what it is worth.
