The fundamentals mentioned in futures refer to the changes in the relationship between supply and demand of the commodity, such as changes in production capacity, policies, weather, inventions and research that may affect the changes in production capacity. Changes in demand may affect policies, weather, inventions and research. The change of fundamentals is generally slow, and it is not easy to change suddenly for a period of time (except for emergencies). But the fundamental situation determines the direction of price operation. After getting the direction of price operation from fundamental analysis, you need to use technical analysis to get specific entry and exit points, because futures are margin trading, and if the entry point is wrong, you can't insist on winning. Stock refers to the operation of a company. According to the current business situation, combined with the company's future development direction and national policies, we can judge whether the future profit is likely to increase or decrease, and make a decision on whether the stock price will rise or fall. But in addition to the fundamental analysis of the stock, it depends on the intention of the main force, and the decision-making power of the stock is more in the hands of the main force. The rise and fall of futures is determined by fundamentals, and the main force only participates as a promoter.
