One of the pillars of our approach at The Rational Reminder Podcast and PWL Capital is the idea of index investing, a concept that is both fundamental and deeply embedded. Today we are very lucky to have John 'Mac' McQuown on the show, who was behind the creation of the first equity index fund. It is hard for us to overstate just how important this contribution has been to the world of finance and any fund managers and investors that share our philosophy. Mac's work back in the 1960s, his position at Wells Fargo, and his contribution to the founding of Dimensional Fund Advisors all speak for themselves, and we are extremely grateful to get some perspectives from this titan of the world of rational and data-driven investing. In our chat, we get to hear about some of the key points in Mac's career and the general arc of the rise of indexing and diversified investing, the key figures that he worked alongside, his thoughts on the future, and the importance of environmentalism in today's world. So, to hear it all from a hero and giant in the space, be sure to listen in with us today.
