PNJ Hit by VND 1.2 Trillion Foreign Net Sell as Proprietary Desks Pile into HDB

Overview

Foreign investors flipped back to net selling on October 2, offloading nearly VND 2.3tn across the HOSE and HNX, with Phú Nhuận Jewelry (PNJ) alone accounting for more than VND 1.2tn of that exit. In the same session, securities firms’ proprietary trading desks reversed their prior net-sell position and bought nearly VND 1.7tn, concentrated overwhelmingly in HDB. The divergence puts PNJ at the centre of a sharp split between foreign and domestic institutional flow.

Key Facts

• Foreign investors net sold nearly VND 2.3tn on October 2, reversing a net-buy of more than VND 3.1tn in the prior session.
• PNJ drew over VND 1.2tn of foreign net selling, more than half the total foreign outflow for the day.
• Proprietary desks net bought close to VND 1.7tn, flipping from a net-sell of roughly VND 289bn the previous session.
• HDB captured nearly VND 1.5tn of proprietary net buying, about 90% of the desk total, followed by VPB at nearly VND 117bn, PNJ at over VND 64bn and HPG at about VND 52bn.
• Foreign net selling also hit VIC (about VND 188bn), TCB (over VND 144bn), VHM (nearly VND 78bn) and STB (about VND 50bn).
• On the proprietary sell side, MWG led at about VND 96bn, ahead of VCB at nearly VND 41bn and MBB at about VND 14bn.
• PNJ closed at 23,050 on October 2; VIC at 224,000, VHM at 67,900 and TCB at 32,250.

What Happened

Foreign investors returned to net selling after a single session of heavy buying, with the October 2 session producing a net outflow of nearly VND 2.3tn. PNJ was the dominant target, absorbing more than VND 1.2tn of foreign selling, which alone exceeded half the market-wide foreign exit. Behind PNJ, foreign money also withdrew from VIC at roughly VND 188bn, TCB at more than VND 144bn, VHM at nearly VND 78bn and STB at about VND 50bn. The buy side was thin, with HDB leading at only just over VND 38bn, followed by DGW and FRT at around VND 21-22bn each.

Proprietary trading desks at securities firms moved in the opposite direction. After net selling nearly VND 289bn in the previous session, they net bought close to VND 1.7tn on October 2. HDB was the overwhelming focus, drawing nearly VND 1.5tn, or roughly 90% of the desk total. VPB followed at nearly VND 117bn, then PNJ at more than VND 64bn and HPG at about VND 52bn. Proprietary selling was comparatively small, led by MWG at about VND 96bn, VCB at nearly VND 41bn and MBB at about VND 14bn. The figures are drawn from the session’s trading-desk flow tracking, not from a company or regulatory filing.

Market Context

PNJ trades on HOSE and closed the October 2 session at 23,050. The stock sits in the personal and household goods sector, where foreign ownership has historically been substantial, making it sensitive to block-level foreign rebalancing. The broader session saw foreign investors net sell across large-cap real estate and banking names including VIC, VHM, TCB and STB, suggesting a market-wide de-risking rather than a PNJ-specific event. Domestic proprietary desks took the other side, but their buying was narrowly concentrated in HDB rather than spread across the foreign-sold names, leaving PNJ with foreign selling only partially offset by about VND 64bn of proprietary buying.

Strategic Significance

For long-term investors, the key signal is the asymmetry between where foreign money exited and where domestic proprietary money entered. Foreign selling was broad and concentrated in PNJ, a consumer-retail compounder with a long record of foreign ownership, while proprietary buying was almost entirely a single-name bank trade in HDB. That pattern implies the PNJ outflow reflects portfolio-level rebalancing or redemption pressure rather than a change in the company’s earnings outlook, since no fundamental disclosure accompanied the selling. The risk is that sustained foreign outflows in a stock with meaningful foreign ownership can pressure the share price independently of operating results, while the proprietary bid in HDB signals where domestic desks see near-term relative value.

What to Watch

• Whether foreign net selling in PNJ continues over the following sessions or reverses, as it did after the prior VND 3.1tn net-buy session.
• Foreign-ownership room and any block-trade disclosures for PNJ on HOSE.
• Whether proprietary desks extend buying beyond HDB into other foreign-sold names such as VIC, TCB, VHM or STB.
• Third-quarter earnings releases for PNJ and HDB, which would test whether flow divergence reflects fundamentals or positioning.
• Broader foreign flow trends across HOSE large caps, given the session’s market-wide net-sell pattern.
