This paper analyzes the trading records of a major discount brokerage house to investigate the disposition effect, the tendency to sell stocks that have appreciated in price (winners) sooner than stocks that trade below the purchase price (losers). In contrast to previous research that has demonstrated the disposition effect by aggregating across investors, our main objective is to identify differences in the disposition bias across individuals and explain this in terms of underlying investor characteristics. Building on the findings in experimental economics and social psychology, we hypothesize that differences in investor literacy about financial markets and trading frequency are responsible in part for the variation in individual disposition effect. Using demographic and socioeconomic variables as proxies for investor literacy, we find empirical evidence that wealthier individuals and individuals employed in professional occupations exhibit a lower disposition effect. Consistent with experimental economics, trading frequency also tends to reduce the disposition effect. We provide guidelines for investment advisors, regulators, and investment communities to utilize our findings and help investors make better decisions.disposition effect, investor sophistication, individual decision making

We analyze cross-sectional and time-series information from 46 equity markets around the world to consider whether short sales restrictions affect the efficiency of the market and the distributional characteristics of returns to individual stocks and market indices. We find some evidence that prices incorporate negative information faster in countries where short sales are allowed and practiced. A common conjecture by regulators is that short sales restrictions can reduce the relative severity of a market panic. We find strong evidence that in markets where short selling is either prohibited or not practiced, market returns display significantly less negative skewness.

Our paper explores a comprehensive sample of small and large corporate bankruptcies in Arizona and New York from 1995 to 2001. Bankruptcy costs are very heterogeneous and sensitive to the measurement method used. We find that Chapter 7 liquidations appear to be no faster or cheaper (in terms of direct expense) than Chapter 11 reorganizations. However, Chapter 11 seems to preserve assets better, thereby allowing creditors to recover relatively more. Our paper also provides a large number of further empirical regularities.

We analyze trading records for 66,465 households at a large discount broker and 665,533 investors at a large retail broker to document that the trading of individuals is highly correlated and persistent. This systematic trading of individual investors is not primarily driven by passive reactions to institutional herding, by systematic changes in risk-aversion, or by taxes. Psychological biases likely contribute to the correlated trading of individuals. These biases lead investors to systematically buy stocks with strong recent performance, to refrain from selling stocks held for a loss, and to be net buyers of stocks with unusually high trading volume.
