In economics, finance, and psychology, risk-seeking (also called risk-loving or risk preference) refers to a behavioral tendency to prefer uncertain options with potentially higher rewards over safer alternatives with lower expected value. In other words, risk-seeking individuals derive greater satisfaction or perceived utility from taking chances, even when the probable outcome may be less favorable. This is a big issue seen in stock trading, for example, in where people take the risk to either hold or sell their stocks depending on past market trends.
