People who get a lot of speeding tickets also engage in risky investing behavior, according to a new study. Finnish researchers compared a speeding ticket database and a database of all the trading portfolios of Finnish households. Their findings suggest that for these speeders, a sensible long-term investment strategy simply isn’t interesting enough for them. They crave the thrill and excitement of churning over their investments more frequently. Each successive speeding ticket and investor received correlated to an 11 percent increase in their portfolio turnover. On average, the stocks they bought didn’t do any better than the ones they had just sold.
