中新经纬5月20日电 A股三大指数低开，沪指跌0.4%，报4152.7点；深成指跌0.53%，报15487.43点；创业板指跌0.48%，报3889.68点；科创综指跌0.58%，报2136.71点。

东吴证券研报认为，整体来看，短期的阶段性高点可能已经较为接近，在不发生极端事件的情况下，市场可能参考9-11月趋势，先短期反弹(若强势甚至可能向新高进发)，再做相对健康的震荡调整，随后可能再次迎来向上机遇。
华泰证券研报称，近期AI主题交易过热风险持续累积，后半周市场有所回调，各类交易型资金热度进入“平台期”。此外，配置型资金高位兑现意愿或更强，观测到ETF资金延续前期净赎回趋势、主动偏股型基金在5月初出现减仓TMT的迹象、主动配置型外资在前期转向小幅净流入后于上期再度净流出。(中新经纬APP)
