Reinganum Anchored in reality or blinded by a paradigm? What’s the future of market cap-weighted indices? Marc Reinganum , a senior executive at State Street Global Advisors , sat down with Institutional Investor Journals to discuss his thoughts on these questions, which are the subject of his article in The Journal of Portfolio Management 40th Anniversary Issue.In this report—containing excerpts from the accompanying video interview-Marc predicts that alternatives to cap—weighted indices increasingly will be incorporated into policy portfolios. He discusses the evolution of the CAPM and the academic and real-life rationale for the proliferation of cap-weighted indices during the 1980s and 1990s and why they are currently losing their sway.
