As an investment analyst, you need to learn a lot, not just look at the K-line. First of all, you need to have an efficient and accurate information collection model. Secondly, you need to know something about macroeconomics, including the industrial chain of products, the relationship between supply and demand, and national policies. In addition, you need to know the spot expertise and the trend of domestic and foreign markets. Third, you need to have some trading experience. It is not enough to have theoretical knowledge without practical experience.
