   Investors face a quandary. Cash offers a return of virtually zero in many developed countries; government-bond yields may have risen in recent weeks but they are still unattractive.

It is hardly surprising that pension funds, insurers and endowments are searching for new sources of return. 2013-07-06, “The rise of smart beta”, in The Economist, volume 408, number 8843, page 68
