ChiNext Index gives up gains, falls more than 1% in afternoon session

The reversal matters more than the size of the move: an index that surrenders an intraday advance and turns decisively negative signals that sellers are willing to press into strength rather than wait for confirmation. For growth-oriented ChiNext constituents, that intraday pattern often reflects fragile sentiment rather than a single catalyst, which makes the absence of a disclosed trigger itself notable. Whether the afternoon weakness reflects broad de-risking or a narrower unwind in a few heavyweights is the open question, and the next session's ability to hold early gains would be the cleaner test of sentiment.
