MSCI added Inter RAO and Sberbank’s preferred share to its emerging- markets index late Wednesday, replacing shares of Rostelecom and Transneft, the company said Thursday.

Inter RAO, the country’s largest electricity exporter, was unchanged at 29.9 kopeks a share, while Sberbank’s preferred shares climbed 0.5 percent to 52.28 rubles.  Rostelecom declined 0.35 percent to 192.38 rubles and the preferred stock of Transneft slumped 5.4 percent to 23,770.11 rubles.

 Sberbank’s preferred shares were first added to the index in 2006 but were removed for some time because of a fall in the company’s market capitalization. Sberbank’s weight in the emerging-markets index will be 0.06 percent, while it will make up 0.88 percent of the Russia index. Inter RAO’s stock is not traded but is expected to be made available in September. Inter RAO will make up 0.5 percent of the Russia index and 0.03 percent of the emerging-markets index.
