The Stupidest Thing You Can Do With Your Money

I highly recommend this Freakonomics podcast (and transcript) about passive versus actively managed investment strategies. It provides historical context for the development of some of the most important ideas in finance (e.g., the efficient market hypothesis) and the implications of these ideas for investing in the long run. Along the way, you get to “virtually” meet with many of the best, brightest and most influential academic and professional finance thinkers who played important roles in shaping this history.

Prior to listening to this podcast, I was not aware of how a quip in a 1974 Journal of Portfolio Management article authored by the MIT economist Paul Samuelson inspired Vanguard founder Jack Bogle to launch the world’s first index fund in late 1975. Samuelson suggested that, “at the least, some large foundation should set up an in-house portfolio that tracks the S&P 500 Index — if only for the purpose of setting up a naive model against which their in-house gunslingers can measure their prowess.” (source: “Challenge to Judgment”, available from

Talk Is Cheap: Automation Takes Aim at Financial Advisers—and Their Fees

From page 1 of today’s Wall Street Journal – how automation is increasingly (and in many cases, adversely) affecting the livelihoods of financial advisors.

Services that use algorithms to generate investment advice, deliver it online and charge low fees are pressuring the traditional advisory business.

It also could mean millions in annual savings for consumers and could expand the overall market for advice.

Derek Zoolander, spherical cows, the Guardian, and econophysics

Wonderful explanation of the logical fallacy associated with dismissing theories based upon modeling assumptions that are not literally true… HT to Scott Cunningham.

In Zoolander, the titular character is presented with a model of a building.  He inspects the model and responds with anger and indignation:

Derek Zoolander: What is this? [smashes the model for the reading center] A center for ants?

Mugatu: What?

Derek Zoolander: How can we be expected to teach children to learn how to read… if they can’t even fit inside the building?
