这2种情况是主力在洗盘，别轻易下车，最后一跌之后必然直线拉升

Group 1 - The stock market is unpredictable, and investors must develop their own investment style through practice and knowledge accumulation [1] - Many investors dream of riding on high-performing stocks but often sell too early due to psychological pressure from price fluctuations [3] - Understanding the strategies and timing of major players in the market can help investors avoid being manipulated and maintain composure during market volatility [3] Group 2 - The timing of the washout process is critical, with different stages requiring different durations to effectively clean out floating shares without losing market interest [4][5] - Initial washouts typically last around 10 trading days, while bottom-building washouts can vary from 2-3 days to several months depending on the technical patterns involved [4][5] - The rapid washout during the price surge phase is usually short, lasting 2-3 days, to prevent excessive market attention [5] Group 3 - Major players use two primary washout methods: horizontal oscillation and aggressive price suppression, each with distinct characteristics and implications for trading volume [5] - Horizontal oscillation involves price fluctuations within a stable range, indicating that major players are not significantly reducing their holdings [5] - Aggressive price suppression creates panic among short-term traders, leading to a quick sell-off, but does not involve substantial selling by major players [5] Group 4 - Examples illustrate the differences between washout methods, such as the case of Taihe Group, which experienced a rapid decline with shrinking volume, indicating a typical aggressive washout [8] - In contrast, Changcheng Information showed a prolonged horizontal consolidation with decreasing volume, suggesting that major players were still in control and preparing for a potential upward movement [11] - Understanding these washout techniques can help investors maintain their positions and develop a rational perspective on market fluctuations [11]
