Vietnam Foreign Flow Turns Net Buy: VIC, FPT Lead VND 401B Session

Overview

Foreign investors turned net buyers on the Ho Chi Minh City session, purchasing a net VND 401.2 billion (roughly USD 16 million), with VIC, FPT, DGW, VPB and HPG the largest matching-board additions. Proprietary trading desks at securities firms also flipped to net buying of VND 295.6 billion, while VN-Index closed up 2 points at 1,829.23. The reversal matters for Vingroup (VIC) because it is the single stock the article identifies as driving index direction.

What Happened

According to the session report, foreign investors bought a net VND 401.2 billion across the market, with VND 283.0 billion of that on the matching board. The buying clustered in information technology, basic resources and retail, with VIC, FPT, DGW, VPB and HPG the leading names. On the sell side, foreign desks reduced financial services and real estate exposure, with VHM, CTG, HDB, VND and MBB the largest matching-board net sales.

Proprietary trading desks moved in the same direction, net buying VND 295.6 billion, of which VND 283.1 billion was matching-board flow. Their strongest sector additions were banking, real estate and food, with E1VFVN30, TCB, FUEVFVND, VCB and HPG the top buys, while VIX, MCH, NAF, ACB and MBB were the largest net sales. The article notes put-through activity was concentrated in bank shares including SSB, STB, HDB and LPB, transacted between domestic investors, and that SBT saw VND 91.7 billion in put-through value.

Market Context

VIC trades on HOSE at VND 247,700 as of 10 September 2026, and the article describes the market as having insufficient cash flow to lift stocks broadly, leaving VIC to steer the index. That concentration showed up in a session where the index swung from a 15-point loss to a 2-point gain, with roughly 90 tickers pulled back to reference price. Deposit rates remain anchored at high levels and liquidity is tightening, with matching value only slightly above VND 14,000 billion. FPT closed at VND 74,500, DGW at VND 44,750 and SBT at VND 23,050.

Strategic Significance

The session marks a shift in the marginal buyer rather than a change in the underlying liquidity problem. Foreign and proprietary desks both returning to net buying in the same session, concentrated in technology, retail and materials, suggests these accounts are positioning in earnings-visible exporters and domestic consumption names rather than the real estate complex they sold. For VIC, the risk is that foreign buying is offset by the stock’s outsized index weight: the article attributes index direction almost entirely to VIC, so any reversal in that single name would erase the flow signal quickly. The banking-heavy put-through activity between domestic parties indicates block positioning continues even as on-screen liquidity thins.

What to Watch

• Whether foreign net buying persists across the next three to five sessions or reverses to the net-sell pattern seen earlier in the month.
• VIC’s ability to hold the VND 247,700 reference area, given its outsized contribution to VN-Index.
• Continued foreign selling in VHM, CTG, HDB, VND and MBB, which would offset headline net-buy figures.
• Proprietary desk positioning in E1VFVN30 and FUEVFVND, which signals index-level rather than single-stock conviction.
• Deposit-rate trends and daily matching turnover on the three exchanges, currently just above VND 14,000 billion, as the key constraint on a broader re-rating.
