The market surged during the first half of today's session on the back of yesterday's excitement to reach a high of 575 points. However, as the VNI showed signs of fatigue in facing the current resistance level of 575 points, profit taking transactions started to kick in, narrowing down gains of large caps. In detail, both oil and gas tickers GAS and PVD had their upside scaled down from 1.6% to 0.8% and from 2.8% to fall flat, respectively.
