HDB Leads Proprietary Desk Net Buying of VND 1,479B as Foreign Investors Sell

Overview

Proprietary trading desks at Vietnamese securities firms net bought VND 1,688B on the HoSE session of 2 October, with HDBank (HDB, HOSE) alone accounting for VND 1,479B of that total. The buying ran against a market-wide foreign net sell of roughly VND 3,375B, and the VN-Index closed down 0.66% at 1,737.71. The divergence puts HDB at the centre of a single-session flow story that investors will test against the bank’s fundamentals.

What Happened

The session opened in the red and drifted toward the 1,730 mark before the VN-Index settled at 1,737.71, a decline of 11.59 points, or 0.66%, according to the market recap. Foreign investors were the clear sellers, offloading roughly VND 3,375B of stock across the exchange. That selling was partly absorbed by proprietary trading books at securities companies, which recorded VND 1,688B of net buying on the HoSE.

HDB dominated that proprietary flow, drawing VND 1,479B of net purchases, far ahead of the next names on the list: VPB at VND 117B, PNJ at VND 64B, HPG at VND 52B and BID at VND 20B. On the sell side, MWG saw the heaviest proprietary net selling at -VND 96B, followed by VCB at -VND 41B and MBB at -VND 14B, with smaller outflows in TCB, GMD, LPB, VIB, REE and DBC. The recap does not identify which securities firms were buying or selling, nor whether the HDB flow was a single desk or several acting together.

Market Context

HDB trades on the HoSE and closed the 2 October session at 28,450. The stock is part of the banking sector, which alongside securities, retail, steel and energy featured in the session’s flow lists. The broader tape was weak: the VN-Index fell 0.66% to 1,737.71 as foreign investors extended a net-selling posture. Against that backdrop, the concentration of proprietary demand in a single bank stock stands out from the more diffuse buying seen in VPB, PNJ and HPG.

Strategic Significance

For long-term holders, the key question is whether the HDB buying reflects a valuation view on the bank or a short-horizon trading position. Proprietary desks are not passive index trackers; a VND 1,479B single-name purchase is a deliberate allocation. If it reflects a view that HDB’s earnings trajectory is underappreciated relative to peers such as VPB and MBB, the flow may signal where domestic institutional money sees relative value in the banking sector. If it is tactical, the position could unwind quickly. The simultaneous foreign selling in the same session suggests domestic and offshore investors are reading the same sector differently.

What to Watch

• Subsequent daily proprietary trading disclosures to see whether the HDB buying is sustained or reversed.
• Foreign net flow data on HoSE over the following sessions, to gauge whether the VND 3,375B sell-off was a one-day event.
• HDB’s next quarterly earnings release and any credit-growth or asset-quality commentary.
• Foreign-ownership room and any block-trade filings in HDB.
• VN-Index behaviour around the 1,730 support level cited in the session recap.
