不能肯定地说，股指交割日大盘必跌与许多因素相关。
2022年的情况取决于全球经济形势、国际关系、国内政策等多个因素。
如果全球经济处于复苏阶段，国内政策也推动经济增长，可能会有利于股指继续上涨。
然而，如果全球经济增长放缓或有不稳定因素，股市可能面临调整的风险。
因此，无法肯定地断定2022年的股指交割日大盘必跌。
投资者应该密切关注市场动态，基于充分的研究和分析，做出明智的投资决策。
Ultimately, it is difficult to predict whether the stock market will fall on the delivery day of stock index futures in 2022. This outcome depends on various factors such as global economic conditions, international relations, and domestic policies. If the global economy is in a recovery phase and domestic policies promote economic growth, it may be favorable for the stock market to continue rising. However, if there is a slowdown in global economic growth or other destabilizing factors, the stock market could face risks of adjustment. Therefore, it is not possible to definitively assert that the stock market will necessarily fall on the delivery day of stock index futures in 2022. Investors should closely monitor market dynamics and make wise investment decisions based on thorough research and analysis.
