The position of stock index futures refers to the position formed by investors buying and selling stock index futures in the futures account opened by the exchange. Positions can be long or short. Long position refers to investors holding long positions in their accounts because they think the market will rise in the future when buying stock index futures. Bears are the opposite. Investors think that the market will fall in the future, so they hold short positions in their accounts.

The position of stock index futures is an important symbol to measure investors' market views. If the market is generally bullish, long positions will increase substantially. On the contrary, if the market is generally bearish, short positions will increase substantially. Therefore, stock index futures positions can reflect the investment mentality and market expectations of market participants and provide reference information for investors.

Stock index futures positions also have a great influence on investors. If the market rises as expected, investors holding long positions can make huge profits. However, if the market reverses, the accumulation of long positions may lead to a lot of capital losses, and it is necessary to stop losses in time. On the contrary, investors who hold short positions will profit from the market decline, but if the market continues to rise, they also need to stop losses in time. Therefore, it is very important for investors to understand the significance and application skills of stock index futures positions.
