Roger Ibbotson Comments on Retirement of Industry Pioneer Rex Sinquefield

Roger Ibbotson commented on the retirement of indexing pioneer Rex Sinquefield in Pensions & Investments. He said, “He did have a missionary zeal. For him, the new religion became efficient markets.” Ibbotson and Sinquefield’s work on developing historical returns data for major asset classes changed the way pension funds and other institutional investors manage their money.
