The characteristics of KDJ KDJ, also known as stochastics, first appeared in the form of KD index, which was developed on the basis of William index and is one of the most commonly used technical analysis tools in the financial market at present.
K and D indicators are developed on the basis of WMS, so K and D indicators are some characteristics of WMS. When reflecting the change of stock market price, J is the fastest, followed by K, and D is the slowest. K indicator is quick to respond, but easy to make mistakes; D indicator reflects a little slowly, but it is stable and reliable.
Application rules
KDJ index is three curves, which are mainly considered from five aspects when applied: the absolute number of KD; The form of KD curve; KD index crossing; Deviation of KD index; The value of the j index.
1. Considering the value of KD. The range of KD is 0 ~ 100, which is divided into several areas: over 80 is an overbought area (the buyer's strength is greater than the seller's strength), below 20 is an oversold area (the seller's strength is greater than the buyer's strength), and the rest are wandering areas. According to this classification, if KD exceeds 80, we should consider selling, and if KD is below 20, we should consider buying.
2. If the values of K, D and J are all greater than 50, it is a bull market and the market outlook is bullish; If the values of k, d and j are less than 50, it is a short market and the market outlook is bearish.
3. Three minutes later. KDJ index diagram, D curve has the slowest running speed and the lowest sensitivity; Followed by K curve, J curve is the most sensitive.
4. When J is greater than K and K is greater than D, that is, the three indicator curves are arranged in a long position, indicating that it is a long market at present; When there is a golden cross in the three indicators, the indicators send a buy signal.
5. When the three indicator curves are arranged in short positions, the short-term trend is downward; When there is a dead fork between the three curves, the indicator sends a sell signal.
6. If the intersection of KD lines fluctuates repeatedly around 50, it means that the market is being sorted out. At this time, it is necessary to observe the dynamics of KD deviation in combination with J value, and then decide the investment action.
After exponential passivation, use skills (1). The k value, d value and j value in KDJ index are less than or equal to 20 at the same time. At this time, passivation has appeared, but it can only be used as the primary condition.
(2) The KDJ index of the price must meet the primary selection conditions for 6 consecutive days or more, during which the K value, D value and J value are always less than 20.
(3) Recently, the turnover has been in a state of continuous shrinking.
(4) In the last three trading days, the J value has crossed both the K value and the D value at least once.
(5) Buy it when the J value is the first to wear 20.
It is a challenging world-class problem to summarize human cognition of the law of stock market fluctuation by means of investment analysis. So far, no theory or method can be convincing and stand the test of time? In 20 13, the royal Swedish academy science prize was awarded to Robert? Schiller and others pointed out that it is almost impossible to accurately predict the trend of the stock market and bond market in the next few days or weeks, but it may be possible to predict the price for more than three years through research.
At present, according to the characteristics and perspectives of research paradigm, there are three main methods of stock investment analysis: basic analysis, technical analysis and evolution analysis. In practical application, they have both connections and important differences. The specific content is briefly described as follows:
(1), Fundamental analysis: Taking the intrinsic value of enterprises as the main research object, this paper makes a detailed analysis of the macroeconomic situation, industry development prospects and business conditions that determine the enterprise value and affect the stock price (general economic paradigm), so as to roughly calculate the long-term investment value and safety margin of listed companies, and compare them with the current stock price to form corresponding investment suggestions. According to the basic analysis, the trajectory of stock price fluctuation cannot be accurately predicted, only when there is enough safety margin? Buy and hold for a long time? , sell after the safety margin disappears.
(2) Technical analysis: taking the intuitive behavior of stock price rise and fall as the main research object, taking the shape and trend of stock price fluctuation as the main purpose, starting with the K-line chart of stock price change and technical indicators (physics or Newton paradigm), this paper summarizes the methods of analyzing the law of stock market fluctuation. There are three controversial assumptions in technical analysis, that is, market behavior is inclusive and digests everything; The price fluctuates in a trend way; History will repeat itself. The popular technical analysis methods in China are Dow theory, wave theory and Gann theory.
(3) Evolutionary analysis: Taking the intrinsic nature of life movement of stock market fluctuation as the main research object, starting from the aspects of metabolism, profit-seeking, adaptability, plasticity, pressure, variability and rhythm (biology or Darwinian paradigm) of stock market, the direction and space of market fluctuation are dynamically tracked and studied, which provides opportunities and risk assessment methods for stock trading decision-making. Based on the essential attributes of stock market fluctuation, evolutionary analysis holds that all kinds of complex causal relationships or phenomena of stock market fluctuation can be found from the basic principles of life movement, which provides a convincing basis for building a scientific and reasonable game decision-making framework.
