GAS leads VN-Index to second day of gains. Trading today followed a similar pattern to Tuesday, with the VN-Index opening lower and reaching its low for the session (below 622) in the first 30 minutes. A rally in the afternoon pushed the market into positive territory to close up 1.59 points, or 0.3%, to 627.02, a second straight day of modest gains. GAS (+2.5%) was by far the top contributor, adding 1.44 points, and was followed by tickers that don't often move the market.
