⏱ 30-SECOND SUMMARY
- VN-Index gained over 18 points during the session, touching 1.841,20, but reversed unexpectedly during the closing auction (ATC), ending down 7,11 points — the highest matching volume across the entire monitoring period.
- Crucially: according to public sources, this reversal was primarily driven by ETF portfolio rebalancing activities ahead of Vietnam’s official upgrade to FTSE Russell’s secondary emerging market status (effective 21/09/2026) — not a broad distribution signal.
- Supporting evidence: market breadth remained positive (185 gainers/130 decliners at close), and foreign investors were recorded net buyers of over 1,250 billion VND in the session — contrary to a genuine selloff scenario.
- Most notable stock: SSB continued rising despite the broad market decline, with RSI reaching 89.6 — an extremely elevated level rarely seen, validating yesterday’s warning report.
VN-Index closed the 18/09/2026 session (Friday) at 1.815,66 points, down 7,11 points (-0.39%).

For the week (14-18/09), VN-Index remains up 20,45 points (+1.14%) overall.

Three stocks selected by TT Score + RS Rating + liquidity criteria: SSB (Banking — requires close monitoring), PET (Retail / Distribution), TLG (Consumer Goods / Office Supplies).
SSB — SeABank Continuing gains, RSI at record levels
| Metric | Value |
|---|---|
| 18/09 Volume | 11.73 million shares — over 3x the 20-day average (3.60 million) |
| RSI(14) | 89.6 — even higher than yesterday’s 88.7 |
Hypothesis revisited: Yesterday’s report warned that SSB’s RSI was at an extremely overbought level (88.7) with potential for a cooling correction. Today’s action shows the anticipated correction has not yet materialized — the stock continues rising even as the broader market declines, with surging volume. This illustrates that an extremely heated stock can maintain that state longer than expected before correcting. The warning about elevated risk remains fully valid — arguably even more pressing now.
TLG — Thien Long Group Breakout following short correction
| Metric | Value |
|---|---|
| 18/09 Range | Open 53.2 → High 55.0 → Close 54.3 (69.6% — upper range) |
| 18/09 Volume | 425.2 thousand shares — approximately 2.7x the 20-day average (158.7 thousand) |
After two sessions of mild correction, TLG breaks out again with expanded range and surging volume — a positive technical signal worth noting, with trend structure maintaining all 8/8 criteria.
PET — Petrosetco Stable, steady improvement
| Metric | Value |
|---|---|
| RSI(14) | 54.6 — neutral-positive, not yet overbought |
PET continues its stable improvement trend without extreme movements like SSB — a technically sound setup with greater durability for monitoring.
