在A股历史上，曾经有多只股票在股价超越茅台之后遭遇断崖式大跌，被称为茅台魔咒，例如中国船舶、安硕信息、海普瑞等等，其大起大落的原因大多都 是题材炒作之后，公司基本面无法支撑高估值。寒武纪目前将近600倍的市盈率，不仅远超国内半导体板块市盈率中位数的130倍，更是远超英伟达的57倍。 更深层的挑战在于产业竞争格局。研究机构伯恩斯坦的数据显示，2024年寒武纪在中国AI芯片的市场份额仅为1%，远低于英伟达的66%和华为昇腾的 23%。而百度昆仑芯3代、阿里平头哥等竞品的大规模出货，以及华为在政企市场的统治力，随时可能会挤压寒武纪的生存空间。 从营收来源上来看，寒武纪的客户集中度风险较为突出。2025年上半年，寒武纪最大单一客户贡献了公司42.5%的营收，前五大客户的营收占比超过了 85%。若字节跳动等关键客户转向自研或者竞品，寒武纪的业绩增长性将遭受巨大挑战。 但是无论如何，寒武纪在资本市场上的亮眼表现，代表了市场对于国产硬科技企业的认可与支持，期待寒武纪能够用硬实力打破茅台魔咒，带领中国芯片产 业杀出重围。 虽然在这场比较当中，贵州茅台似乎沦为了背景板，但是茅台上半年454亿的净利润，依然不是目前的寒武纪可以相 ...
