The VNI rocketed to 633.58, a 6-year peak (6.8% MTD) with bias from its largest constituent GAS (+9.7% MTD). The HNI, which closed at 87.04 (11.2% MTD), also got a boost from oil&gas stocks on momentum from strong 2Q earnings annoucements last month. Notably, PetroVietnam Technical Services Corp (PVS) has taken the mantle from ACB to become the largest compenent of the HNI. However, much of the rally was driven by the retail bloc with foreigners net selling for most of the month.
