Portfolio manager Robert Arnett, who manages two of PIMCO's funds, has some alarming things to say about the environment retirees face in the future. In ten years for every working age person added to the workforce there will be 10 new retirees, the complete reverse of what it was ten years ago when there were 10 new working age persons for every new retiree. The impact of this will take the shape of many more retirees selling stocks and bonds to live on and fewer buyers for the bonds and securities, lowering the prospects for higher prices for bonds and securities. He expects the demand for goods and services to continue with higher prices. He sees stocks giving a nominal return of about 5%, bonds a nominal return of 2-4%, for a balanced portfolio yield of about 4%, during the next 10-20 years. After inflation and taxes the returns will be very thin. Expectations of 10% returns do not take into account deficits, debt, and demography in developed countries, says Arnott.
