Market sentiment worsened as investors worried about the slow recovery of manufacturing activity in Asia, led by China, according to MB Securities Co (MBS).
Concerns were raised following tech giant Apple’s negative quarterly earnings forecast, which may hamper the recovery of the regional industry and manufacturing activities.
In addition, worries about further negative developments due to the coronavirus clouded market sentiment.
On the Vietnamese stock market, investors remained cautious amid these concerns, MBS said in its daily report.
Large-cap companies continued to hold back the market. The large-cap tracker VN30-Index shed 0.53 per cent.
Sixteen of the 30 largest stocks by market value and trading liquidity declined.
Those losers included FLC Faros Construction (ROS), brewer Sabeco (SAB), property firms Vingroup (VIC) and Vincom Retail (VRE), steel maker Hoa Phat (HPG) and dairy company Vinamilk (VNM).
The 16 declining large-caps lost between 0.3 per cent and 6.9 per cent.
Real estate, energy and mining, food and beverage, building materials, and transportation and logistics also underperformed on Tuesday, according to vietstock.vn.
Positive gains were seen in the technology, banking, retail, healthcare and pharmaceuticals, and seafood processing industries.
One positive thing was investors sought opportunities in mid-cap and small-cap items instead of selling large-caps and running away from the market, MBS said.
