Over the next four articles, we will learn the four behavioral investor types and how to deal with each of these types of investors. For readers to understand behavioral investor types, they need to get a fundamental understanding of the 20 behavioral biases I outline in my book. In this article, we will review these biases that are encountered with actual clients, with a description of the bias and a classification of whether the bias is cognitive or emotional. Behavioral biases fall into two broad categories, cognitive and emotional, with both varieties yielding irrational judgments. A cognitive bias can be technically defined as a basic statistical, information processing, or memory error common to all human beings. They also can be thought of as "blind spots" or distortions in the human mind. Cognitive biases do not result from emotional or intellectual predisposition toward a certain judgments, but rather from subconscious mental procedures for processing information.
On the opposite side of the spectrum from illogical or distorted reasoning we have emotional biases. Although emotion is a difficult word to describe and has no single universally accepted definition, an emotion is a mental state that arises spontaneously, rather than through conscious effort. Emotions are physical expressions, often involuntary, related to feelings, perceptions or beliefs about elements, objects or relations between them, in reality or in the imagination. Emotions can be undesired to the individual feeling them; he or she might wish to control their emotions but often cannot. Investors can be presented with emotionally based investment decisions, and may make suboptimal decisions by having emotions affect these decisions. Often, because emotional biases originate from impulse or intuition rather than conscious calculations they are difficult to correct. Emotional biases include endowment, loss aversion, and self-control. We will investigate both cognitive and emotional biases in the next section.
The distinction between cognitive and emotional is an important one, because advisors will want to advise their clients differently based on which types of biases are being acted out. In the next four articles, we will use the biases described here a lot, so I encourage readers to get to know the biases presented here in concept. We will apply them to client situations in subsequent articles.
Loss Aversion Bias
Bias Type: Emotional
Some investors feel the pain of losses more than the pleasure of gains--the essence of loss aversion. This bias prevents people from unloading unprofitable investments, even when they see no prospect of a turnaround. Some industry veterans have coined a diagnosis, "get-even-itis" to this phenomenon....
