9月17日，和讯投顾吴青宇称，从早盘表现看，PCB、CPU开始进入新轮动周期。昨天爆炒的低价股延 续性相对差些，但仍有炒作机会，主要炒作方向在机器人、房地产板块。低价股炒作方向与热点题材板 块相关，并非所有板块低价股都上涨，若要选择炒作低价股，可选热门题材里的，如当下的机器人板 块，或处于反弹周期的房地产板块。早盘主要上涨板块集中在PCB、CPU以及科技线、机器人的其他分 支，这可能是未来较长时间内资金的共识。受美联储利率决议影响，今天大金融板块集体承压，金融三 傻涨跌不一，难以形成合力，这是早盘跳水的重大因素，早盘更偏向资金兑现节点，下午大概率有资金 回流参与对美联储今晚降息决议的资金博弈。明天凌晨有美联储利率决议，先探讨降息幅度，从七八月 份数据看，降息25个基点基本确定，但有人给美联储施压希望降息50个基点，且安排相关人员进入美联 储获得投票权后，降息50个基点预期大幅上升，降息幅度很难预测，只能做相应应对。若美联储降息25 个基点，对大盘是重大利好，指数大概率降息后直接上涨；若降息50个基点，短期内反而是利空，因对 美联储继续降息或降息次数的预期可能下降，指数大概率先跌后涨。美联储降息后主要利好有色和 ...
