ChiNext Index Falls 2% as Optical Chips, Components Lead Decline

The pullback is concentrated in exactly the segments that have carried the ChiNext's tech-heavy profile, so the move reads as a rotation within growth rather than a broad risk-off signal — though the board's narrow leadership means optical chips and components can drag the whole index disproportionately. What matters is whether the selling stays confined to these two sectors or spreads across the wider emerging-industry complex. Whether the weakness broadens beyond optical chips and components is the open question.
