The VN-Index unexpectedly closed lower than it opened on September 23 afternoon, despite staying green for most of the trading time. Losses of oil and gas shares were the main drag.

PV Gas (GAS), the biggest stock on the Ho Chi Minh Stock Exchange in terms of market value, dropped 3.54 percent to 109,000 VND (5.17 USD) a share. Other oil- and gas-related stocks, such as Petroleum Industrial & Civil Construction (PXI), Petroleum Equipment Assembly & Metal Structure (PXS), and Petroleum Pipeline and Tank Construction (PXT), fell to the floor prices which were capped at 7 percent a day.

Consequently, the VN-Index slid 0.25 percent, closing the session at 610.39 points. It is the lowest close in the past month, despite the gainers outnumbering the losers by 120-91.

Seventeen of the top 30 shares – in terms of market value and liquidity – advanced while seven declined. The VN30 added 0.78 percent, ending at 658.31 points.
