🆕 NEW ENTRY — 2563 Beijing Biostar Pharmaceuticals ← Shenzhen Efung Investment Management, first notified at 5.99% Read: Shenzhen PE fund Efung crossed the 5% disclosure threshold in Beijing Biostar H-shares, establishing a fresh reportable substantial-shareholder position.

🆕 NEW ENTRY (intra-group re-allocations, 2026-08-06) — shares shifted between related entities within BlackRock and JPMorgan fund families; aggregate positions rose and remain above 5% across six names: • 2018 AAC Technologies ← BlackRock — 5.04% (increased by 0.14pp) • 6881 China Galaxy Securities ← BlackRock — 5.17% (increased by 0.28pp) • 136 China Ruyi Holdings ← BlackRock — 5.02% (increased by 0.75pp) • 6031 SANY Heavy Industry ← BlackRock — 5.10% (increased by 0.69pp) • 2145 Chicmax Cosmetic ← BlackRock — 5.78% (increased by 1.30pp) • 3323 China National Building Material ← JPMorgan Chase — 5.07% (increased by 0.30pp) Read: Each carries reason 1004 ("ceased to have notifiable interest") while the aggregate percentage rose and holds above 5% — the classic HKEX footprint of a fund-family re-registration between related entities, not genuine market selling.

🏢 BUYBACK — 3661 SG Micro Corp ← JPMorgan Chase (passive re-filing), 15.51% (decreased by 0.62pp from prior filing); issuer buyback involved 384,200 shares @ HKD 84.47 for ~HKD 32.5M Read: SG Micro's share repurchase program triggered a compulsory re-filing for JPMorgan; the net percentage decline suggests some JPMorgan holdings were bought back by the issuer or trimmed alongside it.
