Stocks and bonds both decline, and the market's rebound during the holiday closure is weak. This situation of high-level lack of upward momentum has led many traders to choose to establish short positions when the rebound stalls. When the US and A-shares markets are closed simultaneously and market liquidity is limited, technical pullbacks from high levels are more likely to occur. Against this backdrop, many people place short orders at high levels, planning to profit from the market's technical correction.
