芝加哥期权交易所波动率指数（VIX）因对人工智能估值的担忧以及美联储下一个利率决策的影响而上涨。
-- VIX衡量预期的股市波动性，被广泛视为华尔街的“不安指数”。
-- 周五早间，VIX上涨5.5%，突破21，早先一周则徘徊在17左右。
-- 通常情况下，超过20的水平表示投资者的不确定性增加。该指数距离4月份因特朗普总统的关税计划扰动市场时的高点仍有较大差距。
本周，多位美联储官员对12月份再次降息的可能性持谨慎态度。因政府停摆而推迟的经济数据的发布可能会对市场预期产生影响。
根据CME的数据，期货定价目前表明美联储下个月放宽政策的机会约为50%，相较于一周前的67%和一个月前的95%有所下降。
