其次，利用分化，优化布局。在普涨格局下，很多上涨个股可能只是跟风。我们更应该把注意力放在那 些有扎实逻辑支撑、且上午表现强势的板块核心标的上。对于已经大涨的个股，午后不宜盲目追高，可 以等待分时回调的机会；而对于同样有逻辑但涨幅相对温和的品种，可以多一些关注。 最后，控制仓位，保持主动。上午市场成交额略有缩量，表明增量资金进场并不激进。在成交量没有显 著放大之前，指数的上行空间可能受限，市场更可能以板块轮动和结构行情为主。因此，保持一个进退 有度的仓位，让自己在市场出现震荡时仍有资金可以调动，是更为稳健的做法。 朋友们，我是帮主郑重。午盘收盘，三大指数虽然都收红了，但这红得有点"波澜不惊"，上证指数几乎 就是在原地踏步。不过，看似平淡的水面下，资金的流向却异常清晰——超过3500只个股上涨，但领涨 的板块就那么几个：算力硬件、有色金属，还有近期持续活跃的福建板块和充满未来感的可控核聚变。 这感觉就像一场音乐会，指数是平缓的背景音，而真正的主旋律，早已被几个高亢的声部牢牢占据。 今天上午市场最大的看点，就是 "算力硬件"这条线的全面爆发。从CPO光模块到铜缆高速连接，整个 产业链都被点燃了。这背后的逻辑很硬：无 ...
