On June 16, Sanhua Intelligent Controls (02050.HK) fell 3.28% in regular trading, trading at HKD 28.36/share, with turnover of HKD 153 million. The decline extends recent weakness following the stock's formal inclusion in the CSI Robot Index.
The CSI Robot Index mid-year rebalancing officially added Sanhua Intelligent Controls as a core humanoid robot supply chain constituent, with passive ETF buying completed during late trading on June 12. However, the inclusion triggered a classic sell-the-fact pattern, as arbitrage and quantitative funds that had pre-positioned in the stock weeks ahead dumped shares into the passive ETF buying, creating net selling pressure. Additionally, the stock faced dual passive fund headwinds, as CSI 300-tracking broad-based ETFs simultaneously reduced Sanhua holdings due to decreased weighting.
Compounding sentiment, the company's senior management collectively sold over RMB 420 million in shares earlier this year, with Chairman Zhang Yabo alone cashing out approximately RMB 420 million at an average price of RMB 43.1. Other executives cited children's education expenses as the reason for selling, sparking market controversy given their multi-million-yuan annual compensation packages. Broader robot sector weakness also persists, with peer UBTECH Robotics declining 4.32% in today's session.
