The VN-Index could not sustain its rise on September 17 afternoon as blue chips continued to slide.

Major large-cap stocks like PV Gas (GAS), Vinamilk (VNM), Masan Group (MSN), Hoang Anh Gia Lai Co (HAG) and Vietcombank (VCB) that rose in the morning turned towards the end of the session.

On the Hochiminh Stock Exchange, the VN-Index lost 2 points, or 0.32 percent to close at 625.66 points while the VN30, which tracks the top 30 shares by market value and liquidity, decreased 0.15 percent to end at 665.66 points.

Securities shares replaced oil and gas-related stocks as the biggest gainers on September 17 with Saigon Securities Inc (SSI), HCM Securities Co (HCM), BIDV Securities Co (BSI) and Agribank Securities Corp (AGR) all closing at the ceiling prices.

Liquidity remained high as market volume reached nearly 190 million shares worth 3.612 trillion VND (171.2 million USD).

FLC Group (FLC) once again was the most heavily-traded stock with 21.8 million shares, edging up 0.84 percent to close at 12,000 VND.

On the Hanoi Stock Exchange, the HNX-Index closed nearly unchanged at 90.16 points.

Market volume climbed 60 percent over the previous session, totaling 145 million shares while value of trades increased 55 percent to more than 2 trillion VND (94.8 million USD).

Kim Long Securities Co (KLS) on September 17 claimed the position of the most active stock from PetroVietnam Construction Corp (PVX) with 19 million shares traded. KLS price soared up to 9.6 percent to finish at 13,700 VND per share.

PVX came second on trades of 15.3 million shares, slipping 1.56 percent to end at 6,300 VND a share.

According to analysts at SHB Securities Co, the market outlook in the medium term was still positive. However, the market is likely to become more fragile as money inflows focus on hot stocks like oil and gas companies, securities and penny stocks.

Analysts encouraged investors to take advantage of the rising session to restructure their portfolios to reduce risk.

Foreign investors increased selling on September 17 as their net sell value nearly doubled the level on September 16, reaching 382.2 billion VND (18.1 million USD) worth of shares on the two exchanges.-VNA
