我在这里向大家介绍一种判断股票波动的万能定律，

也就是江恩华尔街一书中的第六号规则（参照第9页）


“Buy or sell individual stocks on reactions of 5 to 7 points. When a market is strong, reactions will run 5 to 7 pionts but will not

   decline as much as 9 or 10 points. However, it is important to watch 10 to 12 points rallies or declines for buying or selling levels

    on the average. The next important point to watch is 18 to 21 points up or down from any important TOP or BOTTOM. "

中文翻译

  “利用股票调整5至7点买卖法则。当市场趋势强劲时，调整通常为5至7点，但是最多不会超过9或10点。应用在指数上，

      要注意10到12点的调整或反弹。下一个需要注意的点位是从重要的顶部或底部开始的18至21点的上或下”
