A-shares reduce their volume as they search for a bottom, with support gradually emerging. Funds rebalancing is creating structural opportunities.

On September 19, the A-share market showed a characteristic of support amidst volatility, with the Shanghai Composite Index fluctuating around the intraday average price line. It briefly turned positive during the trading day, but fell again towards the end of the session due to large sell orders from high market value banking stocks. Although the three major indexes consolidated collectively, the index did not break the previous trading day's low point, indicating that selling pressure is gradually easing. At the close, the Shanghai Composite Index fell by 0.30% to 3820.09 points, the Shenzhen Component Index slightly decreased by 0.04% to 13070.86 points, the ChiNext Index fell by 0.16% to 3091.00 points, and the sci-tech board index was dragged down by adjustments in the technology sector, dropping by 1.28% to 1362.65 points. In terms of market turnover, the three major markets in Shanghai, Shenzhen, and the STAR Market had a total turnover of 2.35 trillion yuan, a significant decrease of 817.2 billion yuan compared to the previous trading day. On the market front, there were signs of momentum funds shifting positions. The sector trends for the day showed a clear "shift between new and old themes", with the previously leading innovation sector cooling off collectively, while defensive and undervalued sectors were outperforming. Several high-priced stocks experienced significant declines, with Shanghai Construction Group hitting the limit down.
