This paper attempts to assemble evidence for the relationship between the product and the financial market. Drawing back on work in industrial organization, we analyze the relationship between profit persistence and expected stock returns. We show that long-run profit persistence together with...

This Paper constitutes a first attempt to analyse the impact of the emergence of new funds on portfolio decisions of mutual fund managers who are evaluated on the basis of relative performance. Recent theoretical literature has pointed to the inefficiencies in portfolio selection caused by...

The transformations of the finance sector linked to the emergence of new actors (pension funds, mutual funds, hedge funds…) and its globalization have changed the rules of corporate governance and the competitive context of industrial companies. The theme of the influence between finance and...

This paper analyses the impact of the emergence of new funds on the portfolio decisions of mutual fund managers who are evaluated on the basis of relative performance within a dynamic model. Recent theoretical literature has pointed to the inefficiencies in portfolio selection caused by relative...

This paper introduces a financial hedging model for global environment risks. Our approach is based on portfolio insurance under hedging constraints. Investors are assumed to maximize their expected utilities defined on financial and environmental asset values. The optimal investment is...

This paper undertakes the issue of portfolio insurance from the perspective of a risk-averse agent requiring his financial wealth to grow at a floored rate in excess of an equity benchmark. The suggested solution is a generalization of the CPPI approach within a two-equity asset framework. The...

“Constant proportion portfolio insurance” is a popular technique among portfolio insurance strategies: the risky part of a portfolio is reallocated with respect to market conditions, via a fixed parameter (the multiple), guaranteeing a predetermined floor. We propose here to use a...

The purpose of this paper is to analyze the gap risk of dynamic portfo- lio insurance strategies which generalize the "Constant Proportion Port- folio Insurance " (CPPI) method by allowing the multiple to vary. We illustrate our theoretical results for conditional CPPI strategies indexed on...
