Vietnamese shares started the week on a negative note amid falling liquidity as large-caps suffered strong selling pressure.
The benchmark VN-Index on the Hồ Chí Minh Stock Exchange lost 0.15 per cent to end the trading session at 1,100.07 points.
More than 789.4 billion shares were traded on the southern bourse, worth VNĐ16 trillion (US$660 million).
Market breadth was negative, with 188 gainers and 321 decliners.
"Liquidity decreased compared to the previous session but was still quite high, showing that supply increased pressure on the market. The current supply at low prices is not high, so the market will be in a state of tension when entering the new week to explore supply and demand," said Việt Dragon Securities Co.
"However, with the current sign of setback, the risk of weakness in the near future is still hidden. Therefore, investors should slow down to observe supply and demand, and should not buy stocks at high prices. Currently, it is possible to take advantage of the market's ability to increase profits or restructure the portfolio."
