International audience; A number of recent works have dealt with ethical investment funds, with a greater focus on the mechanisms by which these funds operate or are profitable. These studies have very rarely focused on their performance. The purpose of this paper is therefore to compare ethical and standard or conventional investment funds in terms of performance, focusing on the case of equity funds in Morocco and using the Sharpe index as a method of assessment. Overall, the statistical study shows a reconciliation of the average returns of the two samples and a divergence in terms of performance and risk. Taken individually, ethical values are well positioned in terms of profitability and much less so in terms of performance. Finally, contingency factors allowed a better understanding of the differences within the ethical group, both in terms of profitability and financial performance, in this case age and size.

Everywhere in the world, and especially in Morocco, the imperatives of sustainable development are imposed on the management of logistics flows. Supply chain management seems to be concerned by new environmental and social considerations. These imperatives concern both the supply chains of products and services. Thus, the requirements of sustainable development have begun to interact with the practices of the Service Supply Chain (SSC) which is a supply chain specific to services. Subsequently, how can sustainable chain management contribute to improving the global performance of the service company? The prospective study carried out revealed that sustainable Service Supply Chain Management, in terms of coordination, information exchange, collaboration and pooling of resources and skills of the different actors can improve the efficiency of the service supply chain and its global performance.
