Individual investors who hold common stocks directly pay a tremendous performance penalty for active trading. Of 66,465 households with accounts at a large discount broker during 1991 to 1996, those that traded most earned an annual return of 11.4 percent, while the market returned 17.9 percent. The average household earned an annual return of 16.4 percent,(More)
I test the disposition effect, the tendency of investors to hold losing investments too long and sell winning investments too soon, by analyzing trading records for 10,000 accounts at a large discount brokerage house. These investors demonstrate a strong preference for realizing winners rather than losers. Their behavior does not appear to be motivated by a(More)
Theoretical models predict that overconŽdent investors trade excessively. We test this prediction by partitioning investors on gender. Psychological research demonstrates that, in areas such as Žnance, men are more overconŽdent than women. Thus, theory predicts that men will trade more excessively than women. Using account data for over 35,000 households(More)
We test and confirm the hypothesis that individual investors are net buyers of attentiongrabbing stocks, e.g., stocks in the news, stocks experiencing high abnormal trading volume, and stocks with extreme one day returns. Attention-driven buying results from the difficulty that investors have searching the thousands of stocks they can potentially buy.(More)
Trading volume on the world’s markets seems high, perhaps higher than can be explained by models of rational markets. For example, the average annual turnover rate on the New York Stock Exchange (NYSE) is currently greater than 75 percent and the daily trading volume of foreign-exchange transactions in all currencies (including forwards, swaps, and spot(More)
People are overconfident. Overconfidence affects financial markets. How depends on who in the market is overconfident and on how information is distributed. This paper examines markets in which price-taking traders, a strategic-trading insider, and risk-averse marketmakers are overconfident. Overconfidence increases expected trading volume, increases market(More)
We develop a multiperiod market model describing both the process by which traders learn about their ability and how a bias in this learning can create overconfident traders. A trader in our model initially does not know his own ability. He infers this ability from his successes and failures. In assessing his ability the trader takes too much credit for his(More)
We argue that mutual fund investors are more sensitive to salient in-your-face fees, like loads and commissions, than operating expenses. Our empirical analysis of mutual fund flows over the last 30 years yields strong support for our contention. We find consistently negative relations between fund flows and load fees. We also document a negative relation(More)
T he Internet is changing how information is delivered to investors and the ways in which investors can act on that information. It has lowered both the fixed and marginal costs of producing financial services, thus enabling newer, smaller companies to challenge established providers of these services. On-line brokerage firms, such as E*Trade and(More)
Using a database of more than 1.85 million retail investor transactions over 1991– 1996, we show that these trades are systematically correlated—that is, individuals buy (or sell) stocks in concert. Moreover, consistent with noise trader models, we find that systematic retail trading explains return comovements for stocks with high retail concentration(More)
