When stock index futures fall sharply, the stock market will also be affected. Especially those investors with high risk and high leverage tend to tie the risk of stock investment with the risk of stock index futures, which leads to the decline of stock market price. In addition, some stocks are affected by the macroeconomic environment, and may also be further dragged down by the decline of stock index futures.

The stock index futures that have fallen sharply usually have a certain early warning function, which indicates that the market risk may be further aggravated. In this case, investors should strengthen their risk awareness, actively avoid risks and look for more efficient investment tools, such as bonds or funds. At the same time, for those investors who already hold stocks, it is necessary to make full stop-loss preparations on the basis of understanding the fundamentals of stocks and the development prospects of the company to avoid aggravating losses.

Although the plunge of stock index futures may have a certain impact on the stock market, in the long run, we cannot overemphasize the correlation between futures prices and the stock market. Investors should start from the rationality and value of investment, comprehensively consider the long-term and short-term returns of investment, stock valuation and the overall situation of the market, and make rational investment decisions. Only by adhering to the principle of risk control can we maintain our basic profitability in a volatile market environment.
