For clearer explanation, when we sell a position and make a profit, it proves that our first decision to buy the stock was correct. However, if one of our stocks has an unrealized loss or no gain, selling that position would demonstrate that we made a poor decision in selecting that stock. This explains why it is easier to sell a winner and why we tend to hold onto losers longer. So, in order to become better investors, we must either teach ourselves or trick ourselves into making better decisions.
