HANOI, Dec 9 (Reuters) - Vietnam's benchmark VN Index climbed 0.45 percent at the break on Monday, boosted partly by buying of an exchange-traded fund, an analyst said. Last Friday the db x-trackers FTSE Vietnam exchange-traded fund (ETF) said it would increase holding of Ma San Group and Danang Rubber Joint Stock Co and also add Petrovietnam Transportation Corp to its portfolio in the fourth-quarter restructuring. MSN shares rose 6.75 percent, DRC gained 1 percent, and PVT rose 3.23 percent by midday on Monday. But a 0.71-percent drop of stocks in dairy product maker Vinamilk kept the index from rising strongly. Two foreign funds would sell a combined 13.4 million VNM in the next month as they restructure portfolios, they said in statements filed via the Ho Chi Minh Stock Exchange last Friday.
