Trading was quite choppy in the morning session as investors were cautious after yesterday's terrorist attack in Brussels. However, just before the mid-day break, the market shook off most of the negative sentiment from the past few days and the index started rising from late morning. Small- and mid-cap stocks were the main drivers of the afternoon rally with the VN-Midcap index and VN-Smallcap index rising by 1.2% and 0.7% respectively.
