There will be some support rebound at 54K and 2.8K in the short cycle. Those who are worried about too much retracement can choose to reduce their positions appropriately at the above points.
The mid-term target of 52K and 2.5K is my firm view this week, but it is definitely difficult to achieve overnight.
The process will be difficult and there will be many rebound trends. If you can't hold on in the short term, consider clearing 54K and 2.8K.
