Quantitative modeling & investing

James Montier, author of Behavioral Finance - Insights into Irrational Minds and Markets, gives us as overview of quantitative modeling exercises and their success rate over predictions made by human experts.

Montier feels that there is a clear body of knowledge that suggests statistical modeling can consistently match or beat the success rate of experienced actors. His article, "Painting by Numbers: An Ode to Quant" is the subject of John Mauldin's latest "Outside the Box" column.

Mauldin describes Montier's article as an important point of reflection for investors on the results of quantitative versus qualitative decision making. See the link for the full article.

Clean Money - John Rubino: Book review

Clean Money by John Rubino 274 pages. Hoboken, New Jersey John Wiley & Sons. 2009. 1st Edition. The bouyant stock market environment of the past several years is gone, and the financial wreckage of 2008 is still sharp in our minds as a new year starts to unfold. Given the recent across-the-board-declines in global stock markets (and most asset classes) that have left many investors shell-shocked, you might wonder if there is any good reason to consider the merits of a hot new investment theme, such as clean energy.

Slate profiles Victor Niederhoffer

Slate's recent profile of writer/speculator, Vic Niederhoffer has been getting some attention from traders and finance types in recent days. I thought we'd take a look at it here too, to offer up some possible educational value from Vic's experiences with trading and loss. Here's an excerpt from Slate's profile of Victor Niederhoffer : " I've enjoyed getting your e-mails. It sounds like you've thought a lot about being wrong. Well, the reason you contacted me, to call a spade a spade, is that I'm sort of infamous for having made a big, notorious, terrible error not once but twice in my market career. Let's talk about those errors. The first was your investment in the Thai baht, which pretty much wiped you out when the Thai stock market crashed in 1997. I made so many errors there it's pathetic.
