股市估值指标一直以来都是投资者们关注的焦点，而PE（市盈率）作为其中最重要的一个指标更是备受瞩目。近年来，随着股市波动加剧和宏观经济形势不确定性增加，人们对于PE背后含义产生了更多的思考与探讨。

首先，我们需要明确PE背后蕴含的内涵。简单地说， PE 是某只股票价格与每股收益之比，在很大程度上代表了该公司未来利润增长预期及当前业绩水平。在分析个别企业时, 高低PEG能够反映出其成长潜力大小；同时也可以通过行业均值、历史均值等进行相互比较, 从而找到具有投资价值且被低估或高估的品种。

然而，并非所有情况下高PE就意味着高风险、低PE就意味着安全可靠。因此，在解读这些数字时还需结合其他财务数据如ROE(净资产收益率)、营运现金流量等因素共同参考才能得出正确判断。

当然还有专家学者持谨慎态度认为过分迷信传统评级体系会使得忽视部分优秀但并不符合常规逻辑定理特征孤芳自赏型公司;甚至可能造成牛群效应导致虚假繁荣局面.
