Why there are so many indexes

The terms passive investing and index investing are often intertwined, but they are not exactly the same thing. Today’s guest is Adriana Robertson, the Honourable Justice Frank Iacobucci Chair in Capital Markets Regulation and an associate professor of Law and Finance at the University of Toronto Faculty of Law and Rotman School of Management. Adriana is interested in index investing and, in this episode, we hear her views on whether or not index investing is passive. Hear facts from her paper on the S&P 500 Index fund specifically, and all of the reasons that it's not passive, as well as some of the issues that are potentially arising from the creation of so many indexes or so-called passive investments. A more recent paper by Adriana, published in The Journal of Finance, surveyed a representative sample of U.S. individual investors about how well leading academic theories describe their financial beliefs and decisions, and Adriana shares the differences in something like value growth from an academic perspective versus a real-world perspective. Find out how investors can go about evaluating the performance of their portfolios and what they should be looking for when deciding which index fund to invest in, as well as why index funds aren’t a meaningful category anyway, factors from Adriana’s surveys that might influence investor’s equity allocation, and the trend towards indexing and whether it will overtake active portfolios. Tune in today for all this and more!
