Biren Technology (6082.HK) tumbled 8% in Hong Kong trading to HK$34.32, dragged by a sector-wide selloff in semiconductor stocks after Wall Street chip names fell overnight. SMIC lost 3.1%, Hua Hong Semiconductor dipped 2.9%, while Tianshu Zhixin and Moore Threads each shed more than 2%.

The pullback came despite a positive earnings preview: Biren guided for first-half 2026 revenue of RMB 1.15 billion–1.3 billion, up roughly 18.5x–21x year-on-year, with losses narrowing 75%–80%, though the company remains unprofitable. A CICC research note flagged Biren as a potential inclusion in the Hang Seng Tech Index rebalance. The board will meet on Aug. 28 to approve interim results and any dividend. Morgan Stanley trimmed its H-share stake to 4.95% on Aug. 11.
