In its worst single-session loss of the past three weeks, the Ho Chi Minh Stock Exchange (HoSE), on which the VN-Index is based, saw 326 stocks lose and just 123 gain.
The benchmark index had continued upwards from the previous day, rising 5 points to 1,044 points in the morning session, before plunging by over 11 points in the afternoon session as investors sought to cash in on short-term gains.
Total trading volume jumped by more than 10 percent over the previous session to VND13.35 trillion ($576.69 million), half of it involving the VN30, a basket of the HoSE’s largest capped stocks.
The VN30-Index for this group plunged 0.97 percent, with 22 stocks losing and eight gaining.
Topping losses was PNJ of jewelry retailer Phu Nhuan Jewelry, which slid 6.9 percent, its floor price.
