Using case studies of two investment companies, this paper highlights that organizations may have “investment tribes,” i.e., groups of individuals who appear to exhibit similar risk tendencies for gambles involving gains or losses, possibly with a wide spread of risk preferences. Tribes and...

This paper investigates the risk and return properties of a trading strategy for the cryptocurrency market. The main predictive power for portfolio formation comes from a simple prospect theory model that only uses price information readily available. The dataset consists of a large body of...

The field of behavioural finance points out various investor biases and heuristics which inhibit optimal investment choices and are sometimes deemed irrational. Although emotions are often viewed as anathema to sound financial decisions, there is a big emotional component that has to be taken...

There is much evidence that passive equity strategies dominate active equity management, but many investors remain committed to active investing despite its poor relative performance. We explore the behavioral-economic hypothesis that investors fall prey to the conjunction fallacy, believing...

The disposition effect is the reluctance to sell assets at a loss relative to a salient point of reference, typically assumed to be the purchase price. Using data on stocks and housing sales, we show that the peak price achieved by an asset during the investor's period of holding constitutes an...

This paper shows that patterns which prior literature has attributed to preferences for selling extreme-ranked positions (rank effects) can be traced to different responses of investors when their portfolio performance fluctuates over time. I show that when investors face poorly performing...

We theoretically show that there is a fundamental disconnect between the disposition effect, i.e., investors’ tendency to sell winning assets too early and losing assets too late, and its common empirical measure, namely a positive difference between the proportion of gains and losses...

We successfully show that it is possible to optimize both for risk and for asset allocation without compromising the optimization of individual goals by introducing the novel concept of a compensation portfolio. Therefore, we solve for the global vs. local optimization paradox by bridging Modern...
