Shares dropped on Thursday, pressured by the slump of large-cap stocks that were hit strongly during the last minutes of the session by increased profit-taking.
On the Ho Chi Minh Stock Exchange (HoSE), the market benchmark dropped 1.05 per cent, to 1,370.21 points.
The market's breadth was negative with only 132 gainers, and 311 losers.
During the session, nearly 810.7 million shares were traded on the southern bourse, worth nearly VND23.8 trillion (US$1.04 billion).
The benchmark's downtrend was due to losses of many large-cap stocks, especially in oil and gas and banking sectors.
The VN30-Index, which tracks the 30 biggest stocks on HoSE, fell 0.60 per cent, to 1,426.87 points.
Of the VN30 basket, 17 stocks slid, while 11 inched higher and two ended flat.
