The Shanghai - Shenzhen - Beijing stock markets had a total turnover of 2912.4 billion yuan, a 134.8 - billion - yuan increase from the previous day. The CSI 500 and CSI 1000 indices, which had large previous gains, faced technical adjustment risks due to profit - taking needs. However, the trading volume remained high, and the medium - to - long - term upward logic of the stock market still existed. Policies promoted the optimization of the supply - demand structure and the recovery of corporate profits. The continuous inflow of incremental funds in the stock market drove the logic of stock valuation repair. In the short term, market funds were divided, and the stock index was expected to fluctuate widely. With the continuous rise of option implied volatility and the medium - to - long - term upward trend of the stock index, it was advisable to continue holding bull spreads or ratio spreads for a mild bullish view [2] 3.
