Foreign ETFs with $1B AUM to Rebalance in September: MCH, TCX, VCK Added

Overview

Two foreign ETFs with nearly $1 billion in combined assets are set to rebalance their portfolios in September 2026, according to MBS Research. The Xtrackers Vietnam Swap UCITS ETF and VanEck Vietnam ETF are expected to add MCH, TCX, VCK, SSB, and CII, while potentially removing SBT and SIP. This rebalancing is likely to drive significant foreign flows into several Vietnamese listed stocks, including SSB, SHB, HPG, and MSB.

What Happened

According to a market strategy report from MBS Research dated August 18, 2026, the two foreign ETFs are preparing for their quarterly rebalancing. The Xtrackers Vietnam Swap UCITS ETF is likely to add three stocks—MCH, TCX, and VCK—based on criteria including a market capitalization above $150 million, average trading value of $1 million, and a free-float ratio of at least 5%. No stocks are expected to be removed from this fund.

The VanEck Vietnam ETF is projected to make more significant changes. SBT and SIP may be removed due to their three-month average trading value not meeting the fund’s criteria. To replace them, SSB and CII are expected to be added. The announcement dates are set for September 4 for Xtrackers and September 12 for VanEck, with the actual rebalancing occurring between September 14 and 18.

Market Context

This rebalancing comes amid ongoing foreign outflows from Vietnamese ETFs. In the first two weeks of August 2026, ETFs investing in Vietnam saw net redemptions of over VND 728 billion, with Kindex VN30 experiencing the largest outflow of VND 754 billion. However, the pace of outflows from Xtrackers and VanEck has been slowing, with June even recording net inflows. The affected tickers trade on HOSE (MCH, SBT, TCX, VCK) and other exchanges, with MCH closing at VND 136,600 on August 19, 2026. The expected buying from these ETFs could provide short-term support to the mentioned stocks.

Strategic Significance

For long-term investors, the inclusion of MCH, TCX, and VCK in the Xtrackers ETF signals that these companies meet stringent liquidity and size criteria, potentially increasing their visibility among international investors. The removal of SBT and SIP from the VanEck ETF may reflect underlying liquidity challenges that could persist. The notable buying in SSB, SHB, HPG, and MSB indicates these stocks are likely to see temporary demand spikes, which could be an opportunity for investors to assess their fundamentals beyond the ETF-driven flows.

What to Watch

• Official portfolio announcements from Xtrackers Vietnam ETF on September 4 and VanEck Vietnam ETF on September 12.
• Actual trading volumes and price movements of MCH, TCX, VCK, SSB, CII, SBT, and SIP during the rebalancing window (September 14-18).
• Subsequent foreign ownership changes in the affected tickers.
• Any revisions to the expected portfolio changes by MBS Research or other analysts.
• Broader ETF flow trends in Vietnam for the remainder of Q3 2026.
