🇭🇰 HKEX DI Report — 2026-08-07

🟢 ACCUMULATING — 1355 Biosysen ← Cheung Ching Mo (and controlled entities: China Regenerative Medicine Tissue Engineering, Osibao Cosmetics Holding & Osibao Cosmetics International), bought 322,580,645 shares @ HKD 0.155 for ~HKD 50.0M; group stake now 44.11% (increased by 15.12pp from prior filing) Read: Cheung Ching Mo's control group injected ~HKD 50M to vault their combined stake from ~29% to 44.11%, a decisive consolidation that dramatically compresses Biosysen's public float and signals powerful insider conviction in the company.

🟢 ACCUMULATING — 3661 SG Micro (H) ← JPMorgan Chase, now 16.51% (increased by 1.15pp from prior filing) Read: Despite one JPMorgan sub-entity executing an off-exchange sale of ~719,700 shares (~HKD 58.4M), the consolidated long expanded by 1.15pp — a prime-broker netting effect rather than a clean directional buy, but the aggregate register grew.

🔴 DISTRIBUTING — 290 GoFintech Quantum Innovation ← Liu Zhiwei, sold/placed 218,750,000 shares @ HKD 1.60 for ~HKD 350M; stake now 24.78% (decreased by 2.13pp from prior filing) Read: Liu Zhiwei trimmed his controlling position via what appears to be a placing of ~HKD 350M, cutting his stake from ~26.9% to 24.78% — a sizable insider disposal worth monitoring for further follow-through.

🆕 NEW ENTRY — 1989 Delton Technology (H) ← Fullgoal Fund Management, bought 392,500 shares @ HKD 115.59 for ~HKD 45.4M; now 5.69% (increased by 0.85pp) Read: Fullgoal Fund Management, one of China's largest mutual fund houses, crossed the 5% disclosure threshold in Delton Technology's H shares, marking a notable institutional endorsement of the auto-electronics component maker.

🆕 NEW ENTRY — 1339 PICC Group (H) ← Wellington Management, bought 9,855,558 shares @ HKD 5.38 for ~HKD 53.0M; now 5.01% (increased by 0.12pp) Read: Wellington Management established its first notifiable 5% toehold in People's Insurance Company of China via a ~HKD 53M purchase, likely reflecting value interest in the state-owned P&C insurer at compressed book multiples.

🆕 NEW ENTRY — 522 ASMPT ← BlackRock, re-aggregated position now 5.18% (increased by 0.21pp; "ceased" notice triggered by intra-group entity re-allocation, not a market sale) Read: A BlackRock subsidiary restructuring — not a fresh market buy — drove this filing; aggregate economic exposure in semiconductor packaging equipment maker ASMPT edged fractionally higher and remains above the 5% threshold.

🆕 NEW ENTRY — 2525 Hesai Group ← BNP Paribas, re-aggregated position now 5.16% (increased by 0.24pp; "ceased" notice triggered by intra-group re-allocation) Read: An intra-BNP Paribas entity reshuffle triggered the "ceased" code while the bank's consolidated long in lidar sensor maker Hesai Group nudged above 5% — bookkeeping paperwork, not a new trade.

🆕 NEW ENTRY — 3323 CNBM (H) ← BlackRock, re-aggregated position now 5.04% (increased by 0.05pp; "ceased" notice triggered by intra-group re-allocation) Read: A near-negligible BlackRock intra-group re-allocation keeps the firm marginally above the 5% filing floor in China National Building Material — no new directional view implied.

🏢 BUYBACK — 2475 Luxshare Precision (H) — BNY Mellon now 7.14% (decreased by 3.98pp due to issuer share activity) Read: Luxshare's aggressive repurchase programme shrank the float enough to move BNY Mellon's passive percentage by nearly 4pp in a single disclosure; no BNY trade occurred, and buybacks at this pace signal strong management conviction in the company's valuation.

🏢 BUYBACK — 1138 COSCO SHIPPING Energy (H) — BlackRock now 6.58% (decreased by 1.59pp due to issuer share activity) Read: COSCO SHIPPING Energy's buyback activity mechanically altered BlackRock's float percentage; BlackRock made no trade and its absolute share count is unchanged.

🏢 BUYBACK — 1787 Shandong Gold (H) — BlackRock now 5.86% (decreased by 1.02pp due to issuer share activity) Read: Shandong Gold Mining's ongoing repurchases continue to concentrate the register in existing institutional hands; BlackRock did not sell.

🏢 BUYBACK — 2145 Shanghai Chicmax (H) — BlackRock now 4.52% (decreased by 0.97pp due to issuer share activity, crossing below the 5% threshold) Read: Shanghai Chicmax's repurchase activity mechanically pushed BlackRock below the 5% filing floor; BlackRock holds the same number of shares and made no disposal.

🏢 BUYBACK — 6031 SANY Heavy Industry (H) — BlackRock now 4.73% (decreased by 0.93pp due to issuer share activity, crossing below the 5% threshold) Read: SANY Heavy Industry's buybacks nudged BlackRock below the 5% threshold by less than 1pp — a purely mechanical effect with no change in BlackRock's absolute position.

🏢 BUYBACK — 268 Kingdee — BlackRock now 7.70% (decreased by 0.62pp due to issuer share activity) Read: Kingdee's buyback programme is gradually tightening the float; BlackRock's stake is stable in absolute share count terms.

⚙️ OPTION/CONVERSION — 3308 Zhongji InnoLight (H) ← Goldman Sachs, subscribed 324,550 new shares @ HKD 1,084.87 for ~HKD 352.1M; now 11.60% (decreased by 0.59pp) Read: Goldman Sachs committed ~HKD 352M to InnoLight's new-share subscription, underscoring conviction in the AI optical connectivity play, though broad placement dilution left its percentage marginally lower than before.

🔵 MAINTENANCE — Securities-lending / prime-broker pool reclassifications; no economic trades executed:

• 3308 Zhongji InnoLight (H) ← JPMorgan Chase — now 15.02% (increased by 1.54pp), lending-pool code 16021 (L)
• 470 Wuxi Lead (H) ← JPMorgan Chase — now 7.79% (decreased by 1.16pp), lending-pool code 16022 (L) Read: Both disclosures reflect shares migrating between JPMorgan's lending and proprietary settlement buckets — routine prime-broker bookkeeping with no directional signal for either stock.
