What Happened
According to market data, proprietary trading desks at securities companies net sold VND 369 billion on HOSE during the session. The selling was concentrated in banking and securities stocks, with ACB recording the largest net sell of VND 82 billion. Other notable sells included FPT (-VND 75 billion), SSI (-VND 61 billion), MBB (-VND 49 billion), and VIB (-VND 34 billion). On the buying side, MWG was the top pick with net buying of VND 21 billion, followed by GVR (VND 18 billion) and VHM (VND 10 billion).
Separately, foreign investors unexpectedly net sold a massive VND 5,760 billion across the entire market, a significant outflow that overshadowed the domestic proprietary selling.

The data was compiled from exchange filings and market summaries.
Market Context
ACB closed at VND 26,250 (+0.96%) on volume of 46.9 million shares on HOSE. The stock has been under pressure recently amid broader market volatility. The proprietary selling of VND 82 billion in ACB represents a notable institutional bearish stance, especially as the bank is one of the largest private banks by market cap. Other heavily sold stocks like FPT (close VND 76,100, -0.52%), MBB (close VND 25,000, -0.79%), and SSI (close VND 27,100, -0.73%) also saw negative price action, reflecting broad-based institutional selling. The VN-Index’s rebound was led by Vin Group and Gelex stocks, but the selling by proprietary desks and foreign investors suggests that institutional participants remain cautious.
Strategic Significance
The simultaneous selling by proprietary desks and foreign investors indicates a shift in institutional sentiment, possibly driven by concerns over valuation, global rate expectations, or domestic liquidity. ACB, as a leading private bank, is often a bellwether for banking sector sentiment. The heavy selling by proprietary desks, which are typically more short-term oriented, contrasts with the longer-term foreign outflow. This divergence may signal that domestic institutions are taking profits or reducing risk ahead of potential headwinds. The buying of MWG and GVR by proprietary desks suggests selective rotation into retail and industrial stocks, but the overall net selling points to a cautious positioning.
What to Watch
- Foreign net flow data for the next several sessions to see if the VND 5,760 billion outflow is a one-off or the start of a trend.
- ACB’s price action and volume around the VND 26,000 support level; a break below could trigger further selling.
- Q2 2026 earnings reports for ACB and other banks, due in July, to assess fundamental support.
- SBV policy announcements on interest rates or credit growth that could impact banking stocks.
- Proprietary trading desk activity in the coming weeks to gauge whether the selling is profit-taking or a structural shift.
