Emerging-market stock funds took in $782 million in the week ended March 21 for a 12th consecutive week of inflows and the longest run of gains since 2010, according to EPFR Global.

Net investment into developing-nation equity funds has totaled $25.72 billion in 2012, compared with outflows of $24.46 billion for the same period of 2011, according to a report e- mailed today by the Cambridge, Massachusetts-based data provider.

So-called Global Emerging-Market funds, or GEM funds, recorded net inflows for the week of $1.02 billion, EPFR said. Asian funds excluding Japan recorded a net outflow of $157 million, Cameron Brandt, EPFR director of research, said by e- mail today.

The streak of consecutive weekly inflows to emerging stock funds was the longest since a 29-week run of gains ended in December 2010.

Dedicated BRIC nation funds recorded a total outflow of $22 million for the week, the first back-to-back weekly redemption for the fund group since January. Dedicated Russia funds saw an inflow of $131 million.

Russia equity funds posted an inflow of $131 million, the eighth consecutive week of fresh money, while Latin American funds recorded an outflow of $119 million, largest redemptions this year.

The average emerging-market equity portfolio posted a 1.8 percent loss for the week, cutting the 2012 advance to 14 percent, Brandt said.

Emerging-market bond funds registered inflows of $851 million to bring the 2012 total to $13.84 billion, the best start to a year on record, EPFR said.
