With a curious mind and keen desire to learn how things work, Robin Wigglesworth has always found the complexity of financial markets fascinating. Now the editor of the well-regarded Alphaville markets blog, Robin has been with the Financial Times since 2008 and through this period he’s covered episodes of crisis in traditional markets, and more recently, within the cryptocurrency realm. Robin shares his perspectives on how vastly the terrain has shifted in the delivery of financial media, pointing to the emergence of Twitter as a source of important information. In Robin’s words, “journalism is best when it is quite heavily criticized”.

The balance of our conversation is about Robin’s excellent book, “Trillions”, a deep dive into the history of index funds and the massive growth in passive investing. Through his work we learn of the key developments and the key people whose contributions led to the juggernaut that is passive indexation today. Laying out the early academic research that called into question the notion that active management consistently generated alpha, Robin walks through the initial, inauspicious attempts to create vehicles that simply bought the market. With a view that the massive growth in passive investing is a very positive development, Robin reflects on some of the risks. In addition to the proliferation of questionable ETFs, he cites concentration – among the money managers, among the index providers and even the proxy vote advisors – as considerations to keep an eye on.

I hope you enjoy this episode of the Alpha Exchange, my conversation with Robin Wigglesworth.
