选股的方法-3

除了前面讲到的1-2-3 rule外还有一个重要的2B rule：
short: A stock trades above its recent high but closes under it in the same day or a few days later. The stock could be shorted once it drops under its recent high. Cut loss it returns back above the signal day's high. see FSLR, X

long:A stock trades under its recent low but closes above it in the same day or a few days later. The stock could be bought once it goes above its recent low. Cut loss it returns back under the signal day's low. see CF, PCU,V
这条规则就是前面提到的在股票整理时，有时到支撑线一下，来探测这条支撑。如果成功，说明这是一个强支撑。如果再次下探，就可鞥买入。 如SWC。
