VHM Leads Foreign, Proprietary Net Selling on Vietnam's FTSE Upgrade Day

Overview

On the first trading session after FTSE Russell formally upgraded Vietnam from frontier to secondary emerging market status, foreign investors net sold more than VND 693 billion and proprietary trading desks net sold VND 446 billion on HOSE, a combined outflow of nearly VND 1,140 billion. Vinhomes (VHM), listed on HOSE, was the single most heavily sold name, absorbing about VND 410 billion of combined net selling. The session shows that the upgrade, effective 21/09, has not yet translated into net foreign buying.

What Happened

Vietnam’s upgrade by FTSE Russell took effect on 21/09, but the first session under the new classification closed with selling pressure from both foreign investors and the proprietary trading arms of securities firms. Foreign investors net sold more than VND 693 billion on HOSE, while proprietary desks extended their selling streak to a second session with VND 446 billion, up sharply from about VND 62 billion at the end of the prior week. The combined figure of nearly VND 1,140 billion marks a reversal from 18/09, when foreign investors net bought close to VND 966 billion.

VHM bore the brunt of the outflow. Foreign investors net sold nearly VND 292 billion of the stock, well ahead of VIC at about VND 115 billion, while proprietary desks sold more than VND 118 billion of VHM. Across both groups, VHM saw roughly VND 410 billion of net selling, far exceeding any other ticker. Money still found selective targets: MCH led foreign buying at nearly VND 107 billion, with VPB, CTG, BSR and MBB also attracting net purchases. VPB was the rare name bought by both groups, drawing about VND 265 billion combined, while VIC and FUEVFVND were sold by foreign investors but bought by proprietary desks.

Market Context

VHM closed at VND 68,100 on 21/09, with VIC at VND 235,000, FPT at VND 66,400 and SSI at VND 20,900. The selling landed on a session when the market’s structural status changed rather than on any company-specific disclosure, and it hit real estate and large-cap index heavyweights hardest. The pattern is consistent with foreign and proprietary desks trimming existing positions into a headline event, even as the longer-term index-inclusion pipeline remains intact.

Strategic Significance

For long-term holders of VHM, the key point is that FTSE Russell’s upgrade is a multi-year flow story, not a day-one event. Passive and benchmark-tracking capital enters in four tranches between September 2026 and September 2027, so the 21/09 selling reflects positioning and liquidity management rather than a change in the inclusion thesis. VHM’s outsized net selling also reflects its weight and liquidity within the VN-Index complex, which makes it a natural funding source when institutions rotate. The offsetting detail is that VPB attracted combined net buying of about VND 265 billion, indicating that foreign and proprietary money is rotating within Vietnam rather than exiting wholesale.

What to Watch

• Foreign net flow data on HOSE over the sessions immediately following 21/09, to see whether the outflow is a one-day reversal or the start of a trend.
• FTSE Russell’s detailed tranche schedule and any interim review announcements ahead of the first September 2026 inclusion.
• Proprietary trading desk positioning in VHM, HPG, TCB and MBB, which led the sell side on 21/09.
• Whether VPB’s combined net buying of about VND 265 billion continues, as a signal of where domestic and foreign money is rotating.
• VHM’s closing price relative to the VND 68,100 level of 21/09, as a gauge of whether the selling pressure is being absorbed.
