对于个股，按相同方法，确定其周期。观察创出极高点和极低点的月份，注意当发生快速上涨和下跌时从每个底部和顶部的月数。通过掌握从重要顶部和底部开始的时间，你就会了解重要时段何时运行结束以及趋势何时发生变化。同时，观察趋势在三月至四月、九月至十月和十一月至十二月附近的季节性变化。

这一切将帮助你挑选股票，发现即将大幅上扬或大幅下跌的股票。你工作和研究得越多，你学的东西越多，才能获得更大的利润。

Go over individual stocks and work out their cycles in the same way. Look up the mouths when extreme highs and lows have been made and note the months from each bottom and top when fast advances and fast declines have taken place. By keeping up the time periods from important tops and bottoms, you will know when important time periods are running out and when a change in trend is likely to take place. Also watch the seasonal changes in trend around March to April, September to October, and November to December.

All of this will help you to pick the stocks that are going to have the greatest advances and the ones that are going to have the greatest decline. The more you work and study, the more you will learn and the greater profits you will make.
