The Illusion of Skill

“The illusion of skill is not only an individual aberration; it is deeply ingrained in the culture of the [financial] industry. Facts that challenge such basic assumptions — and thereby threaten people’s livelihood and self-esteem — are simply not absorbed. The mind does not digest them. This is particularly true of statistical studies of performance, which provide general facts that people will ignore if they conflict with their personal experience.”

I find that, unfortunately, to be terribly true.

For those of you who may be unfamiliar with Kahneman, he is a professor at Princeton and Nobel laureate. He is notable for his work on the psychology of judgment and decision-making, and behavioral economics.

Three Myths of Trading Psychology

Myth #1: Emotions are at the root of trading problems. Yes, emotions can interfere with concentration and performance, but that doesn’t mean that they are a primary cause. Indeed, emotional distress is as often the result of poor trading as the cause. When traders fail to manage risk properly, trading size that is too large for their accounts, they invite outsized emotional responses to their swings in P/L. Similarly, when traders trade untested patterns that possess no objective edge in the marketplace, they are going to lose money over time and experience an understandable degree of emotional frustration. I know many successful traders who are fiercely competitive and highly emotional. I also know many successful traders who are highly analytical and not at all emotional. Trading is a performance field, no less than athletics or the performing arts.Success is a function of talents (inborn abilities) and skills (acquired competencies). No amount of emotional self-control can turn a person into a successful musician, football player, or trader. Once individuals possess the requisite talents and skills for success, however, then psychological factors become important. Psychology dictates how consistent you are with the skills and talents you have; it cannot replace those skills and talents.

 Myth #2: Anyone, with dedicated effort, can get to the point of trading for a living. That is nonsense. How many people make their living from acting or musical performance? What proportion of people playing sports can actually make their livelihood from athletics? Many people play chess or poker, but how many can sustain a living from it?Quite simply, to make a living from any performance activity means that you are consistently good at what you do. Not everyone has the talent, skill, or drive to be that successful—in any field. Across the many traders I’ve met in various settings, from home-based, independent traders to professional ones in firms, the best predictors of trading success have been the size of the trader’s account and the resources available to the trader. If a person were to make 30% per year on their accounts year after year, they would be among the world’s most successful money managers. Most money managers of mutual funds, hedge funds, and pension funds cannot sustain such performance. This leads the trader to accept huge leverage and court a risk of ruin when an inevitable string of losing trades occurs. Indeed, such excess leverage is a main cause of emotional distress in trading. Take a look at how the Turtles made their money: they learned a trading method, learned to be consistent with that method, and were given enough money by Richard Dennis that they could trade multiple markets with enough size to scale into positions in each. Even with those resources, not all of the Turtle students could succeed. Talent, skill, and opportunity are the ingredients of success, and these are relatively normally distributed in the trading population, just as they are relatively normally distributed in the population at large.
