The constituent stocks of the Shanghai and Shenzhen 300 Index are likely to soar now. Reason: the state-level main force entered the market to rescue the market and bought big blue chips. Last Monday, the state-level main force bought them again. Therefore, it can be considered that there are not many chips in the hands of the empty side, and it is difficult to crush the index. At present, the index corresponds to IF 1508 stock index futures discount 123 points, and the futures delivery date is August 2 1. In other words, the state-level main players can achieve the effect of defeating the enemy without fighting by maintaining the current point of the Shanghai and Shenzhen 300 Index until August 2 1, 123, which is leveraged. Therefore, in order to avoid huge losses, short positions are probably their only way out.
