The VN-Index rose for a third day, largely fuelled by higher crude oil prices. Trading was choppy most of the day, and was in negative territory in the afternoon, before a late surge pushed the index to close at its high for the day, up 3.39 points, or 0.5%, to 631.26. Brent crude bobbed above USD52/bbl during Asian trading, helping to bolster optimism in Vietnamese energy shares.
