What Happened

According to data from the trading session on August 10, 2026, proprietary trading desks at securities firms (tự doanh CTCK) were net buyers on the HOSE exchange, with a total net purchase value of VND 319 billion. The buying was concentrated in large-cap banking and retail names, with Techcombank (TCB) receiving the highest net inflow of VND 121 billion, followed by Mobile World (MWG) at VND 100 billion. Other banks such as VPBank (VPB), VietinBank (CTG), HDBank (HDB), and MBBank (MBB) also saw significant net buying.

On the sell side, DMX was the most heavily sold by proprietary desks, with net sales of VND 176 billion, followed by Gemadept (GMD) at VND 25 billion and Vinamilk (VNM) at VND 14 billion. The data reflects the daily activity of securities firms’ proprietary trading desks, which often act as market makers and liquidity providers.

Market Context

On the same day, the VN-Index rose 0.49% to 1,776.77 points, supported by improved liquidity. However, foreign investors were net sellers, offloading approximately VND 281 billion worth of shares across the entire market. This divergence between domestic proprietary buying and foreign selling is a recurring theme in the Vietnamese market, where local institutions often absorb foreign outflows. TCB closed at VND 31,350 on HOSE, while MWG closed at VND 73,000. The banking sector, including TCB, VPB, CTG, HDB, and MBB, saw notable proprietary buying, suggesting confidence in the sector’s near-term prospects.

Strategic Significance

For long-term investors, the proprietary trading activity highlights the role of domestic securities firms in providing liquidity and supporting large-cap stocks during periods of foreign selling. The concentration of net buys in banking and retail names like TCB and MWG suggests that these sectors remain attractive to domestic institutional players, possibly due to strong earnings growth or valuation considerations. The net sell of DMX, a smaller-cap stock, may reflect profit-taking or rebalancing. This dynamic underscores the importance of monitoring both foreign and domestic institutional flows, as they can influence short-term price movements and provide signals about market sentiment.

What to Watch

• Continued proprietary trading flows in the coming sessions to see if the buying trend persists.
• Foreign investor activity, as sustained net selling could pressure the VN-Index.
• Quarterly earnings reports from TCB and MWG for the second quarter of 2026, which may justify the buying interest.
• Any regulatory changes affecting proprietary trading or foreign ownership limits.
• Market liquidity trends, as improved volumes could support further index gains.
