2025-08-04 ⚫ 综述 上周国内股市小幅下跌，连续上涨趋势有所减弱，主要 宽基指数小幅收跌，跌幅均在-1%左右。多重因素导致市场 未能连续第六周保持上涨。第一，上证综指站上 3600 点之 后连续震荡消化止盈压力，上涨趋势放缓。第二，美日、美 欧相继完成贸易谈判，中美谈判影响范围广，短期难以达成 共识，从情绪上给市场以压力。第三，美联储会议继续不降 息，市场流动性预期修正。多重压力下市场出现了一定的回 踩，但整体下跌幅度不大。一方面虽然中美未达成贸易协定， 但谈判继续以延长贸易休战期为重要目标，如果低关税时间 继续延长，国内抢出口的局面得以延续。另一方面，美国最 新非农就业表现较差，又大幅下修前期就业水平，9 月联储 降息概率上升。国内继续推进反内卷和促销费的政策，从周 一市场表现来看市场情绪保持相对乐观。拉长时间来看，当 前宽基指数估值依然较低，经济刺激政策也逐渐发挥效果， 美联储降息逐渐临近，RMB 汇率保持强势，内外部环境继续 改善，继续保持谨慎乐观的观点。 ⚫ 期权市场 从期权市场来看，由于市场整体下跌幅度较小，金融期 权隐波（IV）变化幅度不大，目前金融期权 IV 处于相对适 中的位置。 5 ...

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The weekly market declined to varying degrees, with all three option underlying assets dropping by over 1%. The changes in the position PCR ratios showed divergence, with the position PCR of 50ETF and 300ETF continuing to fall, while the put contract position ratio of 500ETF increased.
