Goldman to JPMorgan Say Sell Emerging Markets After Slide

Wall Street’s biggest banks say the slump in emerging-market assets that left equities trailing advanced-nation shares by the most since 1998 last year will prove more than a fleeting selloff.

Goldman Sachs Group Inc. recommends investors cut allocations in developing nations by a third, forecasting “significant underperformance” for stocks, bonds and currencies over the next 10 years. JPMorgan Chase & Co. expects local-currency bonds to post 10 percent of their average returns since 2004 in the coming year, while Morgan Stanley projects the Brazilian real, Turkish lira and Russian ruble will extend declines after tumbling as much as 17 percent in 2013.
