This paper investigates the disposition effect on the Portuguese stock market, on the basis of a unique database that consists of trading records of 1496 individual investors. We found strong evidence of the disposition effect, studied on the basis of trades, volume and value traded. This...

Behavioural Finance has emerged as a serious contender to the Efficient Markets Hypothesis in the study of asset pricing and capital markets. A major tenet on which it rests is the investor's aversion to loss-induced regret and the consequent tendency to hold losing stocks too long and sell...

Modern Finance has dominated the area of financial economics for at least four decades. Based on a set of strong but highly unrealistic assumptions its advocates have produced a range of very influential theories and models. Nonetheless, in the last two decades a new academic school of thought...

Fund managers can only exhibit selectivity through purchasing (selling) stocks that appreciate (depreciate) more frequently than expected from random occurrence, if stocks are incorrectly priced. We develop a method that can statistically identify fund managers that exhibit net, buy, and sell...
