家人们好，这里是帮主郑重的收评时间。今天这行情啊，用"冰火两重天"来形容一点不为过。三大指数集体收跌，但个股却是涨多跌少，这说明市场内部的 结构性分化特别明显。作为20年的老财经记者，我始终相信，中长线投资要做的不是追热点，而是看透表象背后的真逻辑。 今日行情让我想起2018年贸易战时期——指数萎靡但结构机会喷涌。记住三条铁律：不在情绪高潮时追涨，不在逻辑破灭时死扛，不在产业黎明前撤退。 最后给大家划个重点：当前市场进入"打地鼠"模式，板块轮动快，但中长线的核心逻辑始终没变。消费升级、农业现代化、科技赋能，这些才是真正值得长 期关注的方向。就像我常说的，中长线投资不是百米冲刺，而是马拉松，选对赛道比跑得快更重要。 我是帮主郑重，专注中长线投资20年，明天同一时间，咱们接着聊市场里的真逻辑。 接下来重点聊聊板块。首先是逆势爆发的草甘膦和农化板块。这两天草甘膦概念涨得很凶，中旗股份20cm涨停，广信股份、中农联合也跟着封板。这背后 其实有两层逻辑：一是全球农业政策调整，各国都在推动农业现代化，高效农药的需求持续增加；二是国内企业技术升级，像广信股份采用了环保生产工 艺，成本降下来了，竞争力自然就上去了。不过这里得 ...
