No surprise here: Investors prone to thrill-seeking trade more frequently. Studying a pool of Finnish investors, finance professors from UCLA and the Helsinki School of Economics found that investors' portfolio turnover rates—which measure trading activity—rose 11 percent after each speeding ticket received. The study, Sensation Seeking, Overconfidence, and Trading Activity (.pdf), also found that on average, stocks bought by the thrill seekers performed no better than those they sold.
