What Happened
According to data from HOSE, proprietary trading desks at securities firms bought VND 667 billion and sold VND 861 billion on August 24, resulting in a net sell of VND 195 billion. This reversed a three-session net buying streak. The bulk of the sell-off came from a single stock: VCK, which saw VND 158 billion in net selling, all via block trades. This was the largest proprietary trading session for VCK since its listing in late 2025.
VCK’s inclusion in the FTSE All-Cap index, announced on August 21, likely prompted the block sale. In contrast, GMD led net buying with VND 87.2 billion, also via block trades, while TNT saw VND 39.7 billion in net buying. On an order-matching basis, proprietary desks net sold VND 174 billion, with FPT, ACB, VNM, VIC, and MSN among the most sold.
Market Context
VCK, listed on HOSE, closed at VND 30,350 on August 24. The stock’s inclusion in the FTSE All-Cap index may attract passive fund flows, but the proprietary block sale suggests profit-taking or rebalancing by domestic desks. The broader market, as measured by the VN-Index, rose 1.17% to 1,788.78 points, with foreign investors net buying VND 180 billion. The sell-off in large caps like FPT, ACB, and VNM via order matching indicates selective profit-taking by domestic proprietary desks.
Strategic Significance
For long-term investors, VCK’s FTSE All-Cap inclusion could enhance its visibility among international investors, potentially supporting demand. However, the large proprietary block sale highlights the stock’s volatility and the potential for domestic institutional profit-taking. The pattern of block trades in GMD and TNT suggests that proprietary desks are actively repositioning, possibly ahead of index changes or corporate events. Investors should monitor whether foreign inflows materialize for VCK and whether proprietary desks continue to reduce exposure.
What to Watch
- VCK’s trading volume and price action in the coming sessions, especially any further block trades.
- Foreign ownership changes in VCK, as FTSE inclusion may trigger passive fund buying.
- Q3 earnings reports from VCK and other affected tickers, due in October.
- Continued proprietary net selling or buying trends, as August month-to-date net selling stands at VND 566 billion.
- Any announcements from FTSE Russell regarding index review dates or additional inclusions.
