There’s an old saying on Wall Street that “pigs get slaughtered.” This refers to the habit greedy investors have of hanging on to a winning position too long to get every last tick upward in price. Sooner or later, the trend reverses and the greedy get caught.
Greed is not easy to overcome. It’s often based on the instinct to do better, to get just a little more. A trader should learn to recognize this instinct and develop a trading plan based on rational thinking, not whims or instincts.
