Iv'e seen companies come out with game changing good news an then drop 15% Take a look at Galaxy Resources (Lithium) just signed a 5 year 1 billion dollar deal and dropped 15% right after that. It did have a 100% run up since January so there could be profit taking going on. Now Gold could be a little shaky with the new Tax plan that will really get the equities into a massive bubble, like they are not already lol.
