All approved listings will temporarily go to the Hanoi Stock Exchange and return to HoSE after the system is upgraded.

In recent months, with investors flocking to trade in humongous numbers, the 20-year-old system used by the country’s main bourse has been unable to cope.

Tech giant FPT Corporation is working to upgrade it.

HoSE hosts the largest capped stocks in the country, including blue chips such as conglomerate Vingroup and state-owned lender Vietcombank. Meanwhile, the Hanoi Stock Exchange is home to mid and small caps.

In March, 113,875 new trading accounts were opened, the highest monthly figure ever, taking the total number of accounts to nearly 3.02 million.
