Strictly speaking, accurately speaking, the Shanghai Composite Index cannot be speculated. Because the plate is very big and there are many stocks, it is impossible for any individual or institution to speculate on the Shanghai Stock Exchange Index, theoretically and practically.

However, many investors actually make money through the Shanghai Stock Exchange Index, including but not limited to the following methods: First, by forecasting the Shanghai Stock Exchange Index, they buy and sell large-cap blue-chip stocks and their leading stocks and sample stocks that support the Shanghai Stock Exchange Index; Second, by forecasting the Shanghai Composite Index, buying and selling index funds is the de facto speculative index.

However, it should be noted that the speculation index must be based on the understanding of technology, the ability to observe the market and the financial strength.
