一、半导体狂欢下的冷思考 看着手机屏幕上跳动的数字，又创新高了！8月23日这天，A股市场62家公司盘中创出历史新高，半导体板块尤其亮眼。寒武纪20CM涨停，海光信息、北方 华创、盛美上海这些名字在屏幕上闪烁着诱人的光芒。 作为在金融市场摸爬滚打多年的老手，我太熟悉这种场景了。每次市场出现这种集体狂欢，总会有两种声音：一种是"涨太多了该回调了"，另一种是"这才 刚刚开始"。说实话，这两种说法都他妈是废话。 记得读书时，我的金融学教授说过一句话："市场没有高低，只有对错。"现在才明白其中的深意。所谓高点低点，都是典型的"上帝视角"——事后诸葛亮谁 不会当？ 二、高低是个伪命题 让我说句掏心窝子的话：预测高低就是预测未来，这跟算命有什么区别？我见过太多散户整天纠结"现在是不是高点"，结果错过整个行情；也见过更多人觉 得"已经跌很多了"盲目抄底，结果抄在半山腰。 举个例子，寒武纪从7月低点涨了138%，现在是不是高点？海光信息上半年净利润增长40.78%，这个位置贵不贵？这些问题根本没有标准答案。就像小马过 河，深浅自知。 我在大学时就开始使用量化分析工具，十多年的经验告诉我：真正重要的是看清当下正在发生什么。那些整 ...
