RE:RE:Vector....Yep, vector. For the next few years rational people will be buying or selling based on drill results.
Others will trade based on rumours. And "conventional wisdom" (sell in may and go away, or buy the rumour sell the news, etc). And their patience level. And their perception of opportunities elsewhere. And the state of their personal finances, and their reading of the technical charts or their horiscopes, and what their analyst/broker, or tea leaf/tarot card lady said. And a million other reasons that give the rest of us opportunities to benefit from an irrational market.
