Massive block trades in MSB fuel speculation that global investors are quietly rotating into undervalued Vietnamese banks
MARKET INSIDER – Foreign investors may still be dumping Vietnamese stocks, but one local bank is suddenly attracting aggressive institutional buying — a move that could signal the early stages of a strategic shift into Southeast Asia’s most undervalued banking market.
In a striking divergence from the broader selloff across Vietnam equities, overseas investors snapped up nearly 43 million shares of Vietnam Maritime Commercial Joint Stock Bank (MSB) in a single trading session on May 13, even after heavily selling the stock just one day earlier. The unusual accumulation comes as global funds continue reducing exposure across emerging and frontier markets amid persistent macro uncertainty, high U.S. interest rates, and shifting capital flows in Asia.
MSB shares closed 1.5% higher at VND13,600 ($0.53), while foreign investors bought approximately 44.5 million shares and sold only 1.9 million. Trading data suggests most of the activity occurred through negotiated block deals rather than open-market matching, pointing to institutional positioning rather than speculative retail demand.
The scale of the transactions immediately caught market attention. Block trades in MSB reached roughly VND642 billion ($25 million), with most deals executed at VND12,800 per share — nearly 6% below the stock’s closing market price. Large negotiated transfers have become increasingly common in the bank over recent months. In February alone, nearly 78 million MSB shares changed hands through similar transactions in a single session, reinforcing speculation that long-term investors may be quietly building exposure.
The timing is particularly notable because foreign investors were otherwise net sellers across Vietnam’s stock market during the same session. Overseas funds dumped more than VND1.43 trillion ($55 million) worth of shares on the Ho Chi Minh Stock Exchange, offloading major Vietnamese blue chips including FPT Corporation, Asia Commercial Bank, Vingroup, and Vinhomes.
What makes MSB stand out is valuation. According to Vietnamese brokerage firms, the bank is currently trading at a price-to-earnings ratio of around 7.1x and a price-to-book ratio below 1x — significantly cheaper than many regional banking peers in Southeast Asia. Ho Chi Minh City Securities Corporation recently maintained a “buy” recommendation on the stock, projecting upside potential of roughly 22%.
Operationally, the bank has also shown signs of improving momentum. MSB reported first-quarter 2026 pre-tax profit of nearly VND1.89 trillion, up 16% year-on-year, while total assets climbed to around VND413 trillion ($15.9 billion). Its non-performing loan ratio remained relatively stable at 1.73%, while return on equity stayed above 14% — metrics that compare favorably with several regional mid-tier lenders.
For global investors searching for overlooked growth stories, Vietnam’s banking sector is increasingly difficult to ignore. The country continues benefiting from supply-chain diversification away from China, rising manufacturing inflows, and accelerating middle-class consumption. If foreign institutions are selectively accumulating undervalued Vietnamese financial stocks while broadly exiting the market elsewhere, MSB’s sudden buying surge may prove to be more than an isolated trade — it could be an early signal that smart money is positioning ahead of Vietnam’s next major capital inflow cycle.
