Today on the show we welcome the Head of Investment Solutions at Dimensional Fund Advisors, Marlena Lee. Marlena has a Ph.D. from the University of Chicago where she served as the TA to Eugene F. Fama. She has been at Dimensional for 11 years where a big part of her role is communicating what their research team is doing for the advisors and clients who are using their products. In this fascinating episode, we discuss and define models, factors, and the importance of understanding the risks involved with any investment decision. We talk about the many different reasons why stocks have different returns, and what the research says about underperformance and our expectation of positive premiums. Marlena has some interesting perspectives on whether risk or behavior drives higher returns, and shares some of her biggest lessons gained from working with Eugene Fama, and Dimensional Fund Advisors.
