Sector dominance has shifted dramatically, leaving only a handful of industries in the green, including information technology, insurance, pharmaceuticals, and transportation. Among these, the information technology sector stands out, driven by the positive performance of FPT.
Conversely, the securities sector is among the hardest hit. Several stocks within this group have experienced significant declines, such as VIX and VND, both down 6%, and VCI, SHS, MBS, and CTS, all down 3%. The lone bright spot is the newcomer TCX, which, despite the overall pressure, managed a near 6% increase on its debut.
Many blue-chip stocks are underperforming. MSN and GEX have both dropped by over 6%.
A positive note from today’s morning session is the robust liquidity and foreign investors’ net buying. Trading value reached 30.5 trillion VND, nearly double that of the previous session. Foreign investors net bought over 1.7 trillion VND.

10:30 AM: Heavy pressure from financial and real estate sectors
By mid-morning, buying and selling forces were evenly matched. Market breadth showed nearly 330 gainers and over 330 decliners. However, strong support from blue-chip stocks helped the VN-Index rise to around 1,650 points.
The top 10 contributors to the VN-Index added nearly 14 points, featuring diverse sectors: VIC (real estate), VCB, BID, LPB (banking), TCX (securities), HVN, VJC (aviation), and VNM (consumer goods).
On the downside, MSN, VPL, and NVL weighed on the index, though their declines were not overly severe.
The influence of large-cap stocks was evident in the VN30 group, with 22 out of 30 stocks rising, pushing the VN30-Index up by over 26 points.
Despite the presence of many influential stocks, banking and securities shares performed poorly. Red dominated the financial sector, with VIX, VND, SHB, and VCI falling 2-5%.
The real estate sector remained negative, with NVL, TCH, DXG, and DXS hitting their lower limits. Red spread across this sector, maintaining pressure on the index alongside the financial sector, preventing a breakout.
Trading activity was vibrant, with a value of over 22.6 trillion VND by 10:40 AM.

Opening: Early session tug-of-war
Following yesterday’s sharp decline, market sentiment remains uncertain.
The market opened on 21/10 with both the VN-Index and HNX-Index in the green. Leading large-cap stocks supported this rise, with positive momentum in financial, essential consumer, and information technology sectors. Real estate stocks, however, remained in the red.
NVL started the session negatively, quickly hitting its lower limit at the open.
Early market breadth was balanced, with 260 gainers and nearly 260 decliners, reflecting investor indecision.
During the opening phase, VIC rejoined the rally, contributing nearly 3 points to the VN-Index. Newcomer TCX from TCBS Securities debuted on HOSE, rising nearly 5% and entering the top 10 contributors to the VN-Index.
