What Happened
According to the article, foreign investors continued their net selling trend on May 13, with total net sales of about VND 1,475 billion. The VN-Index fell over 30 points intraday before recovering to close down 3 points at 1,899 points. Trading volume remained high, with nearly VND 30,000 billion traded on HoSE.
On HOSE, MSB was the standout, attracting VND 545 billion in net foreign buying, far exceeding other net-bought stocks like MSN (VND 152 billion) and BSR (VND 106 billion). On the selling side, FPT led with VND 383 billion, followed by ACB (VND 260 billion), VHM (VND 242 billion), and STB (VND 193 billion).

Market Context
MSB closed at VND 13,600 on May 13, up 1.49% with volume of 17.7 million shares. The stock’s strong foreign buying occurred despite overall market weakness and heavy foreign selling in other banking stocks like ACB and STB. The VN-Index’s intraday recovery suggests domestic buying support, but foreign flows remain a key headwind for the market. MSB trades on HOSE.
Strategic Significance
The concentrated foreign buying in MSB, a mid-cap bank, while selling large-cap banks (ACB, STB) and tech (FPT) indicates a rotation within foreign portfolios. MSB’s relatively lower valuation and potential for growth may be attracting foreign interest. The net selling in FPT and VHM suggests profit-taking or rebalancing away from high-valuation stocks. This divergence highlights that foreign flows are not uniformly bearish but selective.
What to Watch
- Continued foreign flow patterns in MSB over the next few sessions to confirm sustained interest.
- Q2 2026 earnings reports for MSB, particularly net interest margin and loan growth.
- Foreign ownership limit changes or any corporate actions affecting MSB.
- Broader foreign net selling trend on HOSE, especially in FPT and VHM.
- VN-Index support level around 1,890-1,900 and any policy response to foreign outflows.
