With the development of productivity and social progress, the enterprise form has been continuously developed and improved. The evolution of an enterprise mainly goes through three stages By the third stage, the main way to learn is to practice and understand. It is not only the practice and understanding of trading, but also the practice and understanding of life. You will realize that the market is just a person, you are dealing with the market, in fact is dealing with a person with deep connotation. When you have a new understanding, you will be the original thought fully understand what you have a new understanding, including your original have no way of technical indicators and way to trade, and analysis. Everyone is contributing to the market. Everyone is working hard for their profits. Everyone has something to learn. At this time, your study is mainly to communicate with people, exchange ideas, experience, experience, even personality. Don't limit yourself to trading and market study. Learn and improve by learning how to get along with people and get along with others. This is the learning of roots. Through this kind of study form atmosphere, calm, objective, face, easy. Atmosphere, calm, objective and face, easy to deal the importance of needless to speak, this style does not come in through the technical behavior can achieve and implementation, nor by increasing your ability to forecast analysis and money management can achieve. Before 2004, I didn't care about the fundamentals, and I didn't think the fundamentals were useful. However, in 2005, I found myself wrong, not in the fundamental way, but in the fact that I didn't use it at all. In 2005, several large transactions were conducted through basic analysis, which was far better than pure technical analysis. Fundamentals can analyze the market, and it is concluded that the approach of interval, and the technical method can be used to test the operation is correct, technical signals can be used to control transaction risk and trading right. The right level of trading can determine the size of your transaction. For me this is really a very meaningful development. And the fundamental reunderstanding comes not from books, but from communication with enterprises, communication with people, and essentially communication with society. Because China's mainstream economics mechanical property right understanding into property of power based on stock, so, in the name of the Chinese norm of the reform of property right will be the eye looks at on the stock of state-owned assets, simple and ridiculous "privatisation" scheme, clear property rights is approximate to "privatization". It was a misreading of coase, a misreading of alchin and even an insult to them. The precise description of property rights should be the right to clarify individual pursuit of wealth. It is not obvious in some analyses, but it is important to note that economic profits include opportunity costs. The profit of an entrepreneur (normal profit) is usually positive, but economic profit can be either positive or negative (loss). That's why the opportunity cost is included: in a completely competitive market, when marginal cost equals marginal revenue, profit maximization or loss minimization conditions arise. If the market price is lower than the total average cost, which means that the economic profit is negative, the entrepreneur needs to compare the value of the loss and the average variable cost. If the business continues to operate, the negative economic profit must not be lower than the average variable cost, otherwise the entrepreneur would rather shut down the company than continue to take the loss.
