Is Book-to-Market Still a Useful Value Measure?

Who better to have on the Rational Reminder Podcast than Professor Ken French? Ken has been a massive inspiration to us and has remained a guiding light for sensible, evidence-based investors over the last few decades! His work with Eugene Fama stands as the seminal work on the subject of passive investment portfolios and we are so delighted to have him on the show today as we talk through some of his thoughts on a variety of subjects. This conversation was recorded near the beginning of the coronavirus outbreak on this side of the world and although Ken does mention the crisis, the situation has developed considerably since then. We start with the basics, with Ken giving us some helpful definitions and perspectives on asset pricing models and active management before we dive into the current market volatility and familiar topics such as risk tolerance and equity premiums. We also get the chance to hear Ken's reflections on a number of his papers, home-country bias, and the value of a good advisor. Some listeners may be surprised to learn that Ken still relies heavily on a financial advisor of his own and he explains exactly what functions this person performs for him and why he values their help so highly! We also discuss better strategies for long-term portfolio allocation, sustainable investing options and more, so be sure to join us for this very special episode, it is not to be missed!
