Shares posted a steep fall on Wednesday as the market was still under selling pressure to take profit due to the previous low-priced purchases.
On the Ho Chi Minh Stock Exchange (HoSE), the market benchmark VN-Index dropped 2.58 per cent, to 1,054.28 points.
The market's breadth was negative with 60 gainers and 364 losers.
During the session, some 814 million shares were traded on the southern bourse, worth over VND12.7 trillion (US$534.7 million).
The benchmark's downtrend on Wednesday was also due to losses of many large-cap stocks. The VN30-Index, which tracks the 30 biggest stocks on HoSE, fell 2.76 per cent, to 1,051.08 points.
All 30 stocks in the VN30 basket went down.
In the VN-30 basket, the worst performers included The Viet Nam Rubber Group (GVR), FPT Corporation (FPT), Masan Group (MSN, Hoa Phat Group (HPG), Vietjet (VJC), Vinamilk (VNM), Novaland (NVL), Sabeco (SAB), Vingroup (VIC), Vincom Retail (VRE), Vinhomes (VHM), Phat Dat Real Estate (PDR) and PVPower (POW).

All 25 sector indices in the market lost ground, including real estate, securities, oil and gas, wholesale, retail, information and technology, food and beverage, rubber production, construction, seafood processing, construction materials, insurance and logistics.
VN-Index corrected when approaching the resistance zone of 1,090-1,095 points. In the scenario of possible further declines, VN-Index will receive support at 1,070-1,080 points. If it successfully holds at this support zone, investors can continue to open short positions, focusing on sectors such as securities, steel, cement, textiles, construction, oil and gas.
