I could be wrong (and hope I am), but I think mainly trigger happy, poorly informed investors are behind this rise. IVAN jumped at just the time news came out about Ivanhoe Mines find. We have seen this before. Certain investors rush to buy on the news and accidentally buy IVAN instead of IVN.
I sold a little at $2.07 and plan to re-buy lower when people realize their mistake and it drifts back down, if I'm right. If I'm wrong... won't be the first time.
