Any of the following characteristics can be considered as an imminent rebound: A、 The annual decline of oversold stocks is usually over 30%, and it would be even better if they could drop by 50%; It is best to choose stocks that have fallen for no reason and are experiencing an unlimited bearish trend. B、 There is no resistance platform formed (i.e. long-term fluctuations at historical lows, recently falling below a new low to form a relatively recent rebound lock up zone), and there has been no rebound market in the past few trading days or on any trading day. 2、 Selection of target stocks The choice of target stocks is not necessarily better with a larger decline. Relatively speaking, individual stocks with short-term trends that are weaker than the overall market trend by 3 times and 3.5 times have relatively higher short-term upward potential and success rate (the overall market index can be stacked on individual stocks). Among them, strong stocks (mainly referring to individual stocks that have recently risen significantly and reached new highs in recent years) and individual stocks that have reached new lows in recent years are the preferred choices. 3、 Time to buy 1. In terms of price, if the opening price the next day is about 2% lower than yesterday's closing price and maintains a flat consolidation pattern, it is appropriate to build a position; If the stock price opens flat or jumps short and opens high, it should intervene after the second dip of the stock price; If there is a significant downward trend after the opening, we should remain cautious and wait for clear signs of stabilization in the next few trading days before intervening. 2. In terms of time, when the market is in a very weak state, its rebound often occurs one hour before the closing. 3. From the perspective of trading volume, the daily trading volume on the first day of the rebound should be more than twice the daily volume of 8 days, and the daily trading volume thereafter should remain above the daily volume of 8 days. If the daily trading volume rapidly shrinks after reaching a daily high, it is often an important signal of a short-term peak. 4、 Risk control When the following conditions are met, it is necessary to actively carry out clearance operations: after the return reaches 5% or more, the upward momentum of the stock price begins to weaken. When the trading volume of a stock rapidly shrinks after reaching a daily high, the daily K-line closes at a bearish candlestick, or the turnover rate exceeds 10% after a continuous rise, be careful not to see the stock price peak. When the stock price falls below the 3-day moving average, some positions should be considered for exit. If it falls below the 5-day moving average, all positions should be liquidated.
