每经记者｜郑步春 每经编辑｜肖芮冬 周一A股上午偏弱震荡，下午走势略转好，收盘各大股指以微涨为主。截至收盘，上证综指微涨0.12点 至3367.58点，其余主要股指涨幅细微，仅北证50显著上涨2.37%。全A总成交额11189亿元，较上周五的 11241亿元略有缩小。 由盘面看，航运港口、化纤、造纸、房地产、环保等板块表现稍强，白酒、矿物制品、工程机械、保 险、银行等板块表现稍弱。 周二央行将公布贷款市场报价利率（LPR），因关税战降温及近期经济数据相对较稳，多数市场人士预 计5月LPR将维持不变，稍后几个月才有望下调。 A股中短期内走势将很大程度上取决于中美后续谈判，投资者目前操作上多半会倾向于保守与观望。预 计在上述重大事项明朗前，A股大概率延续震荡格局，投资者可继续持股观望。 白酒类个股开盘即下跌。据新华社报道，近日印发修订后的《党政机关厉行节约反对浪费条例》，有与 酒相关的文字，具体是：工作餐不得提供高档菜肴，不得提供香烟，不上酒。 其他市场方面，上周五美股三大股指均小涨；周一港股小跌，恒指微跌0.05%，恒生科技指数跌 0.50%。本周二，宁德时代H股将于港交所主板挂牌上市，市场预期较好，近期宁德时 ...
