Crafting Content: Research and Creativity

What if holding just a few “winning” stocks is riskier than it seems? In this episode, Ben and Cameron explore the hidden dangers of concentrated portfolios and unpack the data that makes a strong case for diversification. Drawing from research by Hendrik Bessembinder, J.P. Morgan, and others, Ben lays out the harsh reality behind individual stock returns: the odds are stacked against long-term success. From skewed return distributions and catastrophic losses to behavioral traps like the endowment effect and familiarity bias, this conversation breaks down why most stock pickers lose—and why diversification remains the only “free lunch” in investing. Whether you're holding onto a single stock for tax reasons, overconfidence, or just inertia, this episode is a must-listen reality check on portfolio risk. They also share thoughts on advisor adoption of indexing, the slow shift in Canada, and how a Rational Reminder YouTube video sparked debate between stock pickers and indexers in the comments section. For anyone navigating concentrated positions—voluntarily or otherwise—this episode is packed with data-driven insight and real-world takeaways.
