He is a visiting fellow at Durham University and a fellow of the Royal Society of Arts.

He gave a useful presentation at the CFA Institute’s Annual Conference this week where he systematically reveals the dangerous nonsense underpinning modern portfolio theory so widely followed in finance today.
Here is a direct link to the clip. You will need to advance the play bar to 18:40 to where Montier is introduced.
There are many gems in his talk–such a refreshing relief to hear someone call bullshit rubbish on conventional wisdom in this area. (I gave a similar talk at the CFA Institute Conference in Atlanta in 2008. It was well received, and completely unheeded by the industry, of course.) Existing business models in the money industry are so flawed, endemic and misguided that it is very slow to evolve changes needed. And so the firms, advisors and clients will apparently keep learning hard lessons the hard way for a few more years to come.
