Present market instabilities have prompted great interest on the characteristics of specific portfolios such as minimum variance and equally- weighted risk contribution portfolios as these portfolios do not rely on the estimate of expected returns. Indeed, in turmoil periods traditional market...

This paper presents a framework for portfolio optimization that makes three departures from the traditional mean-variance approach. First, we optimize the portfolio over multiple horizons, reflecting the belief that long-term investors care about intertemporal gains and losses, as well as...

We show in a simple framework that momentum trading can exist in equilibrium and momentum trading is profitable. Properties of the model fit the empirics well. First, the model captures in a parsimonious manner both short-term overreaction and long-term reversals. Second, it predicts that...

This article studies optimal, dynamic portfolio and wealth/consumption policies of expected utility maximizing investors who must also manage market-risk exposure which is measured by Expected Shortfall (ES). We find that ES managers can incur larger losses when losses occur, compared to both...

We determine the optimal amount to invest in a Black-Scholes financial market for an individual who consumes at a rate equal to a constant proportion of her wealth and who wishes to minimize the expected time that her wealth spends in drawdown during her lifetime. Drawdown occurs when wealth is...

We develop two new methods for calibrating subjective expectations regarding the return generating process (RGP) of financial assets without resorting to noisy realized returns. Using finance professionals' expectations of average and extreme returns, volatilities, and probabilities of stocks...

This paper proposes a new method to introduce coherent risk measures for risks with infinite expectation, such as those characterized by some Pareto distributions. Extensions of the conditional value at risk, the weighted conditional value at risk and other examples are given. Actuarial...

We study a weighted co-monotonic risk sharing problem among multiple agents with distortion risk measures under heterogeneous beliefs. The explicit forms of optimal allocations are obtained, which are Pareto-optimal. A necessary and sufficient condition is given to ensure the uniqueness of the...

This paper analyzes optimal risk sharing among agents that are endowed with either expected utility preferences or with dual utility preferences. We find that Pareto optimal risk redistributions and the competitive equilibria can be obtained via bargaining with a hypothetical representative...

Firms, insurance companies, pension funds, and broadly speaking the international community focus already their engagement activities on environmental, social and governance (ESG) issues since it can create long-term shareholder value, by determining the future performance of markets. Indeed ESG...
