Learning to take losses is an essential speculative technique. MOST never learn it. Take losses at once and move on. Take small losses to protect yourself from the big ones.
Beware the 3 obstacles to jumping ship:
– fear of regret ( that the loser will turn out to be a winner when you’ve bailed-out )
– Unwillingness to abandon part of an investment ( become willing to abandon )
– Difficulty of admitting you made a mistake.
