Illusion of Control
People often believe they can influence the outcome of events that are outside their control, such as by wearing a lucky jersey when watching a football game. Helping foster such an illusion in investing are several factors:
- Choice – those who choose their own investments believe they have more control than those for whom the decisions are made.
- Outcomes – positive early outcomes increase investor confidence to a greater degree than negative outcomes reduce confidence.
- Familiarity – the more investors trade, the more control they believe they have.
- Information – the more information available, the greater the sense of control.
- Involvement – active participation in investment groups, etc. foster a greater sense of control.
- Past success – during bull markets, investors often misinterpret luck as skill.
