We provide theoretical and empirical arguments in favor of a diminishing marginal premium for market risk. In capital market equilibrium with binding portfolio restrictions, investors with different risk aversion levels generally hold different sets of risky securities. Whereas the traditional...

Investors show different behaviour in falling markets and in rising markets. This paper demonstrates that the beta of individual stocks varies across the entire return distribution and that the variation depends on the frequency of the returns. While there is a symmetric u-shape increase for...

We propose a novel class of models in which the crash hazard rate is determined by a function of a non-local estimation of mispricing. Rooted in behavioral finance, the non-local estimation embodies in particular the characteristic of "anchoring" on past price levels and the "probability...

We provide theoretical and empirical arguments in favor of a concave shape for the security market line, or a diminishing marginal premium for market risk. In capital market equilibrium with binding portfolio restrictions, different investors generally hold different sets of risky securities....

The explanation of the momentum premium represents an ongoing challenge, triggering the development of multiple risk-based and behavioral models. The paper explores the momentum strategy following a systematic divide-and-conquer approach composed from a sequence of top-bottom steps: dissecting...

The systemic risk induced by a connection among financial objects is generally measured by returns, volatility, interbank loans, etc. Nevertheless, these measures do not capture the microscale component of the interconnections induced by heterogeneous investor activity. In this paper, we exploit...

We construct a new measure related to biased beliefs based on industry relative stock market beta (IRSB) in the Chinese stock market. We find that stocks in the highest IRSB decile generate 12.84% more annualized return compared to stocks in the lowest IRSB decile. The IRSB premium is not driven...

We study how the distribution of stock returns is influenced through investor opinion by applying expectile regression to abnormal NASDAQ returns over the period April 2015 - August 2019. Thereby, we differentiate between different aspects of investor opinion: investor perception, attention and...

This paper proposes computational framework for empirical estimation of Financial Agent-Based Models (FABMs) that does not rely upon restrictive theoretical assumptions. We customise a recent methodology of the Non-Parametric Simulated Maximum Likelihood Estimator (NPSMLE) based on kernel...
