A股今天最大的变化，是科技股全面走弱了。 说实话，对今天的这种走势还是出乎意料的，因为昨天收了一根小阴线，要是今天直接来个阳线反包，情况就立即转向多头了，没成想到的是，今天竟然跳 水了，这样的话，对市场接下来的走势又要重新判断了。 从这两波跳水的结果看，早上那波跳水之后沪指的反抗还比较明显，甚至下午13点开盘之后还可能出现红盘，结果下午最终跌幅扩大了，沪指最低到了3870 点，连10日线也跌破了。 说这个现象主要是想阐述两个问题： 其一要关心中际旭创的走势，今天虽然CPO当中的新易盛和天孚通信走得比较强，但是与中际旭创的走势对比，我觉得这是典型的补涨，此后要防止补跌的 情况出现，到时候对科技板块的冲击还会再次出现； 其二科技股是这波行情的引领者，如果科技走弱，市场会有联动效应的，就比如今天因为科技下跌，新能源也跟着下挫了，新能源汽车盘中的跌幅达到了 1.8%，估计在未来两天这种负面的扩散效应还会出现。 实在意想不到，A股今天竟然跳水了，这次历史又要重演？ 而科技股当中的核心龙头中际旭创对全天的走势带来了负面影响，全天的跳水可以分为两个时间段： 第一个时间点是早上10点14分之后，中际旭创开启了一波盘中跳水，直 ...
