Credit Suisse has for several years now put out an annual Credit Suisse Global Investment Returns Yearbook 2013 is out now.
It’s worth reading in its entirety for the insights. I don’t agree with everything there, and I certainly don’t agree with the widely held view (not among the authors) that the universe of countries included in the survey is supposed to be somehow representative of the world.
The countries chosen have an absolutely clear bias in their selection. They are successful economies with successful financial markets. They are included by virtue of their long-term success and capital growth and returns for investors.
The authors know this, but many readers don’t. The returns per this survey are an overly rosy view of possible future returns.
