What Happened

According to data compiled from trading sessions, the market capitalization of Vietnamese securities companies has contracted significantly since the start of 2026. As of August 19, 2026, the total market cap of 39 listed securities firms was approximately 505,000 billion VND, a decline of about 48,000 billion VND (8.7%) compared to the last trading day of 2025. The sector had reached a record high of 610,000 billion VND on March 4, 2026, but has since retreated nearly 60,000 billion VND even after including two new listings.

SSI, the largest decliner, saw its market cap fall by 17,130 billion VND to 58,226 billion VND, a 22.7% drop. Part of this decline is attributed to a cash dividend payment of 1,000 VND per share, totaling 2,501 billion VND, which reduced market cap. The remaining 14,629 billion VND loss was due to share price depreciation. Other major decliners include VPX (down 9,563 billion VND), VCI (down 5,869 billion VND), and VND (down 5,633 billion VND). SHS fell 28.2% to 13,312 billion VND, dropping out of the top 10.

In contrast, HSC (HCM) increased its market cap by 9,355 billion VND to 33,546 billion VND, a 38.7% gain, moving from 8th to 6th place. This was driven by a rights issue of 2,700 billion VND and price appreciation of 7,519 billion VND, partially offset by dividend payments of 864 billion VND. TCX maintained its leading position with 109,452 billion VND, up 0.8%.

Market Context

SSI, listed on HOSE, closed at 19,400 VND on August 19, 2026, reflecting the broader sector downturn. The securities sector’s decline is more pronounced than the VN-Index’s 3.24% drop, indicating sector-specific headwinds. The sector’s market cap has been volatile, with a peak in March 2026 followed by a sustained decline. The underperformance may be linked to lower trading volumes, regulatory changes, or profit-taking after a strong 2025. The entry of new listings like LPS and UPS has added to the sector’s total cap but has not offset losses.

Strategic Significance

For long-term investors, the divergence within the sector is notable. While most securities firms have seen market cap declines, HSC’s 38.7% gain suggests that capital-raising activities and strategic positioning can drive outperformance. SSI’s decline, partly due to dividend payments, may be temporary, but the price-driven loss indicates investor sentiment has weakened. The sector’s overall contraction reflects broader market conditions and possibly reduced brokerage activity. Investors should assess each firm’s capital adequacy, business diversification, and ability to navigate market cycles. The rise of new entrants like TCX and LPS signals increasing competition, which could pressure margins and market share for established players.

What to Watch

• Q3 2026 earnings reports from major securities firms (SSI, VCI, VND) for revenue and profit trends.
• Trading volume on HOSE and HNX; a sustained decline could further pressure sector valuations.
• Regulatory changes affecting margin lending or brokerage fees.
• Any additional capital raises or M&A activity among securities companies.
• SSI’s next dividend or share buyback announcements, which could impact market cap.
