China Cybersecurity Stocks Open Sharply Higher; Sinovatio Hits Third Limit-Up

A synchronized limit-up open across multiple cybersecurity names points to a sector-wide re-rating rather than a single-stock story, with the breadth of gainers suggesting a thematic catalyst rather than company-specific news. The intensity — a third consecutive limit-up and an instant lock at the open — signals crowded, momentum-driven positioning that can unwind as fast as it builds. The open question is whether follow-through broadens beyond the early movers or concentrates further, and whether the move holds once the initial rush fades.
