Vietnam Foreign Net Buying Hits VND 2.6 Trillion; FPT Leads as VN-Index Gains 20 Points

Overview

Foreign investors returned to net buying on Vietnam’s stock market in the week of September 14-18, with total net purchases of VND 2,613 billion (~USD 104.5 million), led by FPT, HDB, and BSR. The VN-Index rose 20.45 points (+1.14%) to close at 1,815.66.

What Happened

During the week of September 14-18, the Vietnamese stock market experienced sharp tug-of-war between buyers and sellers. Early in the week, the VN-Index came under pressure and retreated to around 1,790 points amid broad-based selling across sectors. However, strong demand quickly emerged in banking and securities stocks, then spread to other sectors, helping the index reclaim the 1,800-point level. By week’s end, the VN-Index had gained 20.45 points (+1.14%) to close at 1,815.66.

Foreign investors were a positive factor, unexpectedly returning to net buying for most of the week ahead of Vietnam’s official reclassification as a secondary emerging market by FTSE Russell. According to market statistics, cumulative net buying over the five sessions totaled VND 2,613 billion. On HOSE alone, foreign investors net bought VND 2,659 billion, while HNX saw net selling of VND 98 billion and UPCoM recorded net buying of VND 52 billion. FPT attracted the largest net inflow at VND 508 billion, followed by HDB (VND 462 billion) and BSR (VND 423 billion). MCH, SSB, MBB, and VCB also drew significant foreign demand. On the selling side, VIC was the standout with VND 1,073 billion in net sales, far exceeding VHM at VND 771 billion, VIX at VND 206 billion, and VND at VND 131 billion.

Market Context

FPT Corp (HOSE: FPT) closed at VND 71,700 on September 18, 2026, and led foreign net buying for the week. The technology sector has been a consistent beneficiary of foreign inflows, and FPT’s inclusion in the FTSE Russell secondary emerging market index may further support demand. The broader VN-Index’s 1.14% weekly gain reflects resilience in banking and securities stocks, which offset selling pressure in real estate names like VIC and VHM. The market’s recovery from the 1,790-point area to above 1,815 underscores improving sentiment ahead of the FTSE reclassification.

Strategic Significance

For long-term investors, the return of foreign net buying ahead of Vietnam’s FTSE Russell secondary emerging market upgrade signals potential for sustained capital inflows into large-cap, liquid names. FPT’s leading position in the net buy list highlights its appeal as a technology leader with stable earnings and exposure to Vietnam’s digital transformation. The divergence between foreign buying in banks and technology versus selling in real estate suggests a rotation toward sectors with clearer earnings visibility and policy support. The FTSE upgrade could catalyze further foreign participation, particularly in index-eligible stocks like FPT, VCB, and MBB.

What to Watch

• FTSE Russell’s official reclassification effective date and any subsequent index rebalancing flows.
• Foreign net buying trends in FPT, HDB, and BSR in the coming weeks to confirm sustained interest.
• VN-Index resistance at the 1,820-1,830 level and whether it can hold above 1,800.
• Continued foreign selling in VIC and VHM, and whether it spreads to other real estate names.
• Q3 earnings releases for FPT and major banks, expected in October, for fundamental confirmation.
