any analyst who tries to pick the top in a parabolic move up is trying to be remembered as a genius. if he is wrong nobody will remember his prediction.
Yes, but if any such analyst happens to be correct, they'll be referred to for decades as having "prophetically picked the top of the great bull"...and will be in continual high demand. So perhaps making such a call is a shrewd move as the downside is nearly non-existent.
