The power of psychological influences must never be underestimated. Greed, fear, suspension of disbelief, conformism, envy, ego and capitulation are all part of human nature, and their ability to compel action is profound, especially when they’re at extremes and shared by the herd. They’ll influence others, and the thoughtful investor will feel them as well. None of us should expect to be immune and insulated from them. Although we will feel them, we must not succumb; rather, we must recognize them for what they are and stand against them. Reason must overcome emotion.
