The VN30-Index for HoSE’s 30 largest caps gained 0.68 percent, with 18 gainers and 11 losers.

PNJ of jewelry retailer Phu Nhuan Jewelry topped gains this session, rising 6.9 percent to its ceiling price. The stock was on its fifth straight gaining session, with brokerage Bao Viet Securities (BVSC) saying in a recent report that Covid-19 posed mid- and long-term opportunities to the jewelry chain by making business harder for smaller jewelers.

Next were VNM of dairy giant Vinamilk, up 5 percent, CTD of construction giant Coteccons, up 4.1 percent, and BVH of insurance firm Bao Viet Group, up 3.4 percent.
