My guest this week for the third time is Michael Mauboussin. If there is a major question about markets and investing, Michael has usually written one of the best pieces of research on that topic. Today’s conversation is a mix of several of his research pieces, but focuses on the sources of alpha. The framing of the conversation is the brilliant question “who is on the other side” of a given trade. If you are buying, who is selling, and why? Knowing the answer to this question is one key to understanding where excess return comes from. As is usual with Michael, we also explore tons of other interesting ideas that will serve as food for thought. Please enjoy. For more episodes go to InvestorFieldGuide.com/podcast.
