Wow, in this age of having to say (and publish) the "right thing" for fear of causing offence or "causing people to ask questions of themselves they don't like quasi-offence", big respect to Rob and his publisher for putting this article out there.

These are the questions that need to be debated with calm and sane voices otherwise they are left simply to the under-informed to make assumptions.

Over nearly 30 years of investing, I came to recognise some of my own bias towards my home market and this caused me to look for it in my news sources...
Rob is right to be asking these questions of himself and others. Kudos to the CFA for giving him the platform to do so.
