What Happened
According to data from HOSE, proprietary traders (tự doanh) were net buyers on August 20, purchasing VND 1,109 billion and selling VND 601 billion, resulting in net buying of VND 508 billion. Including warrants and fund certificates, net buying reached VND 587 billion. Among 62 stocks traded by proprietary desks, 29 saw net buying of at least VND 1 billion, while only three stocks saw net selling above that threshold — the fewest since January 8, 2025.
HPG led the buying spree with VND 66.5 billion, followed by VIC, FPT, STB, and VNM. The banking sector was a standout: 16 bank stocks were traded, with total net buying of over VND 160 billion, representing 32% of market-wide proprietary net buying. This marked a sharp reversal from August 18, when banks saw net selling of over VND 160 billion.
The activity came ahead of FTSE Russell’s August 21 announcement of the official Vietnam stock list for the FTSE GEIS index. This follows the April 2026 indicative list of 23 Vietnamese stocks that met screening criteria based on December 31, 2025 data. The official list will be based on updated criteria, and Vietnamese stocks will enter the index starting September 21, 2026, with weights phased in over four tranches: 10% in September 2026, 20% in March 2027, 35% in June 2027, and 35% in September 2027.
Market Context
On August 20, VN-Index rose 0.44% to 1,734.24 points, with HOSE turnover of VND 13,472 billion, down from VND 14,929 billion on August 19. Foreign investors were net sellers, offloading VND 617 billion worth of stocks, equivalent to 28.9 million shares. The proprietary buying, particularly in large-caps like HPG (HOSE), VIC (HOSE), and FPT (HOSE), suggests domestic institutions are positioning ahead of the FTSE Russell announcement, while foreign investors remain cautious. HPG closed at VND 21,150, FPT at VND 69,800, STB at VND 74,500, and VIC at VND 202,000 on August 20.
Strategic Significance
The FTSE Russell upgrade is a pivotal event for Vietnam’s equity market, as inclusion in the FTSE GEIS index is expected to attract significant foreign passive flows. The phased inclusion starting September 2026 means that stocks on the official list will see incremental demand over the next year. Proprietary traders’ aggressive buying, especially in banks and blue-chips like HPG, suggests they are front-running expected index-related inflows. For long-term investors, the key question is whether the upgrade will lead to sustained foreign participation or merely a one-time rebalancing effect. The divergence between domestic proprietary buying and foreign selling highlights the uncertainty, but the structural shift toward emerging market status could enhance liquidity and valuation multiples for included stocks.
