Its revenues rose by 66% to VND3.42 trillion though it had targeted a growth of only 4%.
The state-owned company owns 100% of the Ho Chi Minh Stock Exchange (HoSE) and Hanoi Stock Exchange (HNX).
Some 60% of its revenues and profits came in the first half of the year when trading was regularly worth VND30 trillion a day and the benchmark VN-Index rose to a record 1,528 points.
The HoSE management said investor sentiment was hit in the second half by global economic challenges, geopolitical tensions, inflation, and violations of stock laws in Vietnam.
VNX was established in 2021 with a charter capital of VND3 trillion.
