Sacombank (STB) attracted investor attention during the day with a whopping 14.6 million shares traded at the ceiling price of 18,200 VND (0.87 USD) a share, worth 267 billion VND (12.7 million USD).

Newly-listed FIT Investment Co (FIT) continued to be the most active share on the Hanoi bourse, with 1.6 million shares traded at 13,000 VND a share.

"However, this is also the time many investors are waiting to buy bargain stocks. When investors are pessimistic, the market usually rebounds," they wrote in a report.
