Besides worrying about the short term psychology, I always make a point of not losing sight
of the longer term and the fact more trading has taken place there. Sometimes, the valuation
given during a different time span in the past is more legitimate than what’s presently taking
place, especially if the fundamentals have improved in the meantime.
