Institutional views are divided: firms such as Jufeng Investment Advisory believe recovery momentum remains, but whether trading volume can continue to expand and third-quarter earnings materialize are key validation points. The strategy team at Huaan Securities judges that the market will likely continue to trend weak overall in late October. Short-term consolidation may persist, with directional selection potentially awaiting confirmation from trading activity and third-quarter earnings.
