中国经济网北京12月17日讯 深圳报业集团旗下财中社昨日报道《谁动了谁的蛋糕？东北证券两首 席群内"互撕"》显示，东北证券（000686.SZ）电子行业首席分析师李玖和计算机首席分析师赵宇阳在 TMT大群里因为海光信息的覆盖问题进行了长达34分钟的争吵。 赵宇阳于2020年9月进入证券行业，先后在西部证券、华西证券任职，今年5月13日起在东北证券 执业，担任计算机行业首席分析师。 财中社的报道还显示，Wind数据显示，2025年上半年券商分仓佣金收入为44.58亿元，行业同比 下滑中位数达25%；东北证券分仓佣金收入仅有0.51亿元，同比下滑56.12%，佣金席位占比仅 1.15%，排名行业第26位。行业整体分仓佣金本就处于下行，东北证券的下滑甚至超过了行业平均，研 究所内部就会更倾向于"把有限资源集中到更能带来回报的方向"，天然刺激"热门标的"争夺。 中国经济网记者致电东北证券了解情况，对方认为此事属于公司内部事项，研究所分析师在电子行 业和TMT行业的业务上本来就有一些交叉，也是正常的，对公司业务的正常开展没有太大影响。 天眼查工商信息显示，东北证券股份有限公司(曾用名：锦州经济技术开发区六陆实业股份有限 ...

又见券商首席工作群"互怼"！ 来源：谦益头条 据媒体报道，近日东北证券TMT大群内爆发分析师"互怼"，电子组分析师李玖（TMT组长）与计算机 &AI方向分析师赵宇阳因研究覆盖边界重叠，双方对"海光信息""国盾量子"等热门个股展开"争夺战"。 李玖要求赵宇阳取消对海光信息、国盾量子的覆盖，认为其覆盖的GPU、PCB、材料、液冷、铜箔、散 热、光学、存储等多个方向跨了边界，影响电子组小分析师的蛋糕；赵宇阳则反驳称海光信息属计算机 方向可覆盖的范围，质疑李玖因自己派点上升就以"边界"之名限制方向拓展，且拒绝取消系统内的覆盖 申请，双方争执升级至"有你没我，有我没你"的激烈程度。 双方争议的背后，实际上反映了卖方研究团队对热门板块及资源的分配问题，甚至可以上升至普遍的职 场资源争夺问题。 某头部券商分析师指出，卖方佣金空间持续压缩，扎实做研究越来越难，"内卷"情况反而愈演愈烈，这 对行业长期发展无益。 原标题：《"有你没我，有我没你"！两大券商首席爆发海光信息"争夺战"，聊天记录流出……》 来源：中国基金报 作者：晨曦 炒股就看金麒麟分析师研报，权威，专业，及时，全面，助您挖掘潜力主题机会！ 近期，一份东北证券TMT ...

日前，东北证券研究所TMT组长李玖与计算机首席分析师赵宇阳深夜争执的截图，在业内广泛传播， 两人围绕海光信息（688041，市值4718.41亿元）、国盾量子（688027，市值519.24亿元）等标的的覆盖 权展开交锋。 李玖认为，赵宇阳跨界覆盖了过多电子组的股票，这样既不专业，也会影响其他分析师，要求赵宇阳取 消覆盖一些热门标的。而赵宇阳则不以为然，认为李玖这么做是向他所在的电子组倾斜，作为TMT组 长，他不应该这样没有格局，计算机分析师也有学习其他相关行业的权利。 两人争执不下，从业务边界之争升级到"有你没我，有我没你"的决绝态度，将卖方研究行业长期存在 的"抢标的"问题再次暴露在公众视野中。 为争夺标的覆盖权，两名首席起争执 协会官网信息显示，赵宇阳今年5月加盟东北证券，此前曾任职于西部证券、华西证券等机构。据慧博 智能终端，自今年9月以来，其发布的多篇研报确实覆盖了不少传统计算机领域之外的上市公司，包括 液冷、铜箔、电子布等与电子行业相关的标的，这也成为此次冲突的直接诱因。而李玖作为电子行业首 席及TMT组长，既要维护电子组分析师的利益，又要协调跨领域研究的边界，在资源分配与团队平衡 中陷入两难，最 ...
