It would be wonderful to be able to successfully predict the swings of the pendulum and always move in the appropriate direction, but this is certainly an unrealistic expectation. I consider it far more reasonable to try to (a) stay alert for occasions when a market has reached an extreme, (b) adjust our behavior in response and, (c) most important, refuse to fall into line with the herd behavior that renders so many investors dead wrong at tops and bottoms.
