（原标题：和讯投顾李炜：题材轮动补涨！谁是新主线？） 7月17日，市场走得非常不错，大家持股的这个体感也算是应该蛮舒服的。和讯投顾李炜分析，因为今 天的题材和这个指数都有不同程度的修复。那么下一个阶段的话，我觉得需要重点留意一个事儿，而且 也是这两天市场给的我一种感觉，留意接下来会不会有一些机构容量票，走出那种强者恒强，走出那头 那种龙头之下，如果有那么这种趋势类型的票会不会是接下来下一阶段的风格做切换的核心？这个是要 保持高度关注的。另外像这种趋势容量票，如果有站出来它背后的概念，它背后的产业链，那都可以围 绕它找一些机会，这就是相当于潜在的去看一看在指数进行修复背后以及这些趋势容量票背后有没有核 心的主线。 现在这个时间节点我觉得应该是要保持高度的观察，所以就意味着每天大家自己可以复复盘，为什么会 有这样的一个感觉，但是大家自己有兴趣啊也可以通过成交量观察一下。昨天200亿出现长长上引线的 那个 Cpo光模块的龙头，今天直接给了反包再创新高，啊这就加强了这些趋势大票的风格，当然它呢并 没有扩散开，可能只是带着PCB在涨。最近还有一个点就是由于它不断的在创新高，所带动了一些低位 的一些机构抱团的票，这些低位 ...

注意两个关键点位：沪指要是跌破3330点且成交量缩到万亿以下，赶紧减仓避险；反过来如果放量突破3360点，科技成长股又能浪起来！记住帮主说的，现 在市场处于政策底和经济底之间的磨人阶段，中长线投资者千万别被短期波动带偏节奏。 下周重点盯紧两件大事：一个是美联储5月15日的议息会议，虽然市场赌不加息，但鲍威尔的讲话可能暗藏玄机；更关键的是周二美国4月CPI数据，要是通 胀超预期，全球市场都得抖三抖！国内方面，5月PMI和社融数据也要盯，还有中美关税谈判进展，这些都可能成为行情催化剂。 第一大赛道还是科技成长！但记住要挑硬核标的。AI算力、半导体国产化这些政策力挺的方向，回调就是机会。比如CPO光模块龙头中际旭创，北向资金最 近天天加仓，业绩确定性摆在那儿。第二赛道消费复苏，五一假期数据超预期，旅游、免税、家电这些板块值得关注。格力电器、中国中免现在估值还在地 板上，性价比杠杠的！第三赛道防御配置，银行股最近走独立行情，建设银行都创历史新高了，高股息策略在震荡市就是压舱石。 仓位建议保持五成，进可攻退可守。科技股要是跌破20日均线分批低吸，但别碰PEEK材料这些纯概念炒作。消费股可以等回调到年线附近抄底，像中国中 ...
