The Credit Suisse Global Investment Returns Yearbook and Sourcebook are produced for the Credit Suisse Research Institute by London Business School professors, Elroy Dimson, Paul Marsh and Mike Staunton. They are the global authority on long-run investment returns. The Sourcebook, which analyses the long-term worldwide performance of stocks, bonds, bills, inflation and currency, was published on February 7. The Yearbook is published today.

The 2011 Yearbook reports substantial profits from strategies that aim to enhance income. This surprising evidence spans 21 countries and periods of up to 111 years. At a time when investors find it challenging to generate the income they need and when they are concerned about accelerating inflation, this new research is exceptionally topical.
