5月16日，上市公司重大资产重组新规落地，政策给重组松绑。 今天，多只重组题材概念股涨停，成为了市场的一大风景线。 那么，如何寻找重组题材的潜力公司呢？今天达哥给大家分享几个选股思路。 首先，大股东实力雄厚，未上市的优质资产多。这一点，我相信大家都理解，就不展开谈了。 其次，上市公司的大股东或实控人是央国企。 截至目前，已有多份引导规范央国企市值管理的制度文件出炉，旨在提升上市公司发展质量，增强核心 竞争力，推动上市公司积极运用市场化工具回馈投资者。 从"乌鸡变凤凰"的角度来说，在达哥看来，大股东或实控人是央国企的上市公司，其大股东持股比例在 30%左右或以下，以及业绩较差，那么其就有动力进行并购重组。 再次，上市公司是大股东少有或仅有的上市平台，这类公司也有一定的重组预期。 因此，炒并购重组与炒垃圾股，虽然两者有较大的交集，但不能简单地画上等号。 比如中航黑豹通过重大资产出售及发行股份购买资产的方式，实现了沈飞集团的上市。 在重组之前，大股东金城集团持有中航黑豹的股份比例不到20%，这正是达哥上文提到的大股东持股比 例在30%左右或以下的情况。 我们回到市场。 今天，A股三大指数震荡整理。截至收盘，上证指数 ...
