各位朋友好，我是帮主郑重。干了20年财经记者，现在专研中长线投资，最近A股市场真是热闹——刚送走美国贸易协议的"72小时倒计时"，这边半年报业 绩预告又掀起了新波澜。今天咱就聊聊这57家发布预告的公司里，那13家净利润预增超100%的"尖子生"，看看他们的成绩单背后藏着啥门道。 从行业来看，这13家公司主要集中在新能源、科技、消费升级这几个赛道。新能源行业有政策撑腰，市场化改革推动新能源全面参与电力交易，长期利好。 科技领域AI和物联网持续发力，像芯朋微的工业芯片、国脉科技的养老社区AI应用，都是紧跟趋势的布局。消费方面，惠而浦、孩子王这些公司抓住了内 需回暖的机会，业绩自然亮眼。 作为中长线投资者，咱们得盯着这些行业的核心逻辑。新能源的长期成长性明确，但短期可能会受市场波动影响；科技行业技术迭代快，得选真正有技术壁 垒的公司；消费行业比较稳，但要关注需求是否持续。另外，业绩预告虽然好看，但正式财报出来前还得留个心眼，看看有没有水分，比如非经常性损益占 比高不高。 最后说点实在的，市场现在对业绩确定性越来越看重，7月是半年报披露的关键期，资金会往这些业绩预增的公司扎堆。但咱别盲目追高，得看公司的长期 竞争力和 ...
