2025 4th International Conference on Portfolios, Global Marketing and Economic Environment (PGMEE 2025) was held in Sao Paulo, Brazil during August 23-24, 2025. This conference aims to provide an academic sharing and exchanging platform for researchers, practitioners, and educators to present and discuss the most recent innovations, trends, and concerns as well as practical challenges encountered and solutions adopted in the fields of portfolios, financial security, risk management, global marketing, asset pricing, investment policy and economic environment. The success of PGMEE 2025 is due to the high scientific level of all the contributions as well as to the enthusiasm of all the attendees. The member of the technical committee did a precious job in selecting the papers that were accepted for presentation and for inclusion in this book of proceedings among those that were initially submitted. Beside the authors, participants, we would like to thank the members of the organizing committee, reviewers and volunteers, whose work was fundamental for assuring the smooth running of the conference. We hope PGMEE 2025 can develop into persistent success in future years, involving participants and speakers from all corners of the world. And we believe that with the strong support of all participants, professors, scholars, this conference will be more distinctive. PGMEE Organizing Committees Sao Paulo, Brazil
