The VN-Index pushed higher again - it's ninth consecutive gain - thanks to a surge in energy names. The index rose quickly to 691 in early morning trading and peaked above 692 in the afternoon, but then pulled back sharply to dip into negative territory before recovering to close up 1.83 points, or 0.3%, to 688.55. Oil & gas (+6.9%) was the best performing sector, bolstered by a 6% jump in Brent crude oil prices
