In fact, the relationship between them is interactive! For example, if a company has a huge amount of funds and wants to make money, there are two ways: first, do more in stock index futures, and then buy a large number of Shanghai and Shenzhen 300 stocks to push up the stock price! After the second high, short the stock index according to your position! Then gradually sell all the stocks, so that you can earn double!
This is the reason why stock index futures help rise and fall! Stock index futures are earlier than stocks 15 minutes! This 15 minute is the pricing time of stock index futures. According to all kinds of information to predict today's stock price, and then the stock will make corresponding performance according to the opening situation of stock index futures!
