作者 |远禾 数据支持 | 勾股大数 据（www.gogudata.com） 近日，一明星赛道逆势上涨，接连迎来多个涨停，那就是——培育钻石。 近一段时间以来，黄河旋风直接收获三连板，四方达、盛能源、ST亚振，也相继涨停。 涨停潮背后，是10月9日，商务部、海关总署公告，经国务院批准，决定对人造金刚石微粉、人造金刚石单晶、人造金刚石线锯、人造金刚石 砂轮等相关超硬材料产品实施出口管制。 Wind数据显示，10月9日以来，超硬材料指数上涨16.64%，其中，惠丰钻石、四方达、力量钻石均涨超50%。 而今年以来，培育钻石板块的17只个股中已有5只股价翻倍，ST亚振今年股价更是已涨近600%，较年内最低点翻了8倍。 不过，作为一个高度依赖出口行业，出口管制真的能让培育钻石板块彻底翻身吗？ 01 回顾过去，在这一波强势行情之前，培育钻石企业已经陷入了长时间的阴影。 原本主营中高端家具的ST亚振，2021年以来累计亏损已经超4亿元。2025年5月6日起，公司股票被实施退市风险警示。 今年上半年，在涨停潮中收获三连板的黄河旋风，今年上半年归母净利润亏损2.99亿元，自2022年以来，黄河旋风的净利润已经连续三年同 比下滑 ...
