When stock index futures arrive, we should give up the past experience and return to the most basic point of the stock market, that is, whether the company's performance can support the stock price. At this time, the stock market is the most basic point, and these years have been concepts, and concepts have been constantly added, which makes us forget this basic point. The advantage of the introduction of stock index futures is that it can find this basis point, prevent the occurrence of asset bubbles, and use the power of hedging to make the stock market develop healthily. But in this case, it is terrible for retail investors. For example, in the cold winter, retail investors have already spent the winter, but this winter is also colder than in previous years. For example, the current weather, this year Beijing ushered in the coldest winter in 30 years, but is it the coldest? Don't! It's that we have been spending a warm winter. As soon as the warm winter is over, we feel particularly cold, but cold can make us clear-headed and think clearly about the nature of our investment!
