How Dimensional Is Going Beyond Indexing


Index funds are often viewed as low-cost, passive investments designed to avoid subjective decisions and to simply deliver the returns of an asset class.

In this five-part video series, we take a closer look at some of index investing’s inefficiencies. Joel Schneider, Deputy Head of Portfolio Management for North America, examines the implications of how indexes are constructed and managed—and explores what Dimensional believes is a better way to invest.
