Investors Behaving Badly: Overconfidence

This article cites Professor Brad Barber’s research about investor overconfidence. From 1991-1996, Barber and co-author Terrance Odean set upon a study of more than 66,000 households with brokerage accounts to look for a pattern of overconfidence in common stock purchases. Their hypothesis was that overconfident investors would tend to turn over their portfolios more frequently than those who were less confident.
