ChiNext ETFs surge over 4% as index rebounds in afternoon trade

The notable detail is the breadth of the move: several separate ChiNext-tracking ETFs from different issuers all clearing 4% suggests broad, index-level buying rather than a quirk in one fund's pricing. The intraday reversal from negative to positive territory is the more telling signal, since it implies demand emerged during the session rather than at the open. Whether that afternoon momentum carries into the next session, or fades as a single-day bounce, is the open question worth watching.
