OK, get that but the Feb rise was preceded by basically 1 month of falling like a rock then in augst it tried to get back up but got hammered down. This time it has been preceded by a steady and prolonged decline. (serious question). Obviously no 2 scenarios are ever the same however in your experience are runs like these normal or do you really need to factor in the circumstances of each occasion in which case is it really a matter of the market gradually building tension a bit the same way minor tremors can indicate the more likely build up of a major earthquake ?
Fundamentally and especially with bios having such a long gestation one should be able to pretty clinically pick the check points that will generate price rise (and pull back) however that is obviously a flawed assumption. In this instance we actually know very little more today than yesterday so the price drivers of jitters and manipulation far outweigh the fundamentals of logic and objectivity.
