美国股票基金三周来首次净流出：单周撤出66.5亿美元
LSEG Lipper数据显示，截至10月28日的一周，美国股票基金录得三周来首次单周净流出，投资者净撤出66.5亿美元，为10月7日以来首次。大型科技公司财报季临近、超级智能基建开支不断攀升引发的回报担忧，让资金在财报公布前转趋谨慎。
分规模看，大盘基金净流出38亿美元，部分回吐了前一周87.2亿美元的净流入；中盘基金流出21.1亿美元，小盘基金流出8.32亿美元，多盘基金流出3.03亿美元。
行业基金则逆势录得35.2亿美元净流入，为三周来最大，主要由科技基金45.4亿美元的净买入带动；金融与医疗行业基金分别流出7.13亿与7.01亿美元。当周微软公布了强劲的现金流并给出稳健的云增长展望，Alphabet与亚马逊的财报则令投资者失望。
债券基金当周吸引20.4亿美元净流入，前一周为净卖出9.69亿美元。其中市政债基金、一般国内应税固定收益基金与通胀保值基金分别录得17.4亿、13.1亿与10.8亿美元净买入；短中期政府与国债基金、短中期投资级基金则分别流出24.8亿与15.9亿美元。
货币市场基金当周净流出476.6亿美元，与前一周约149.7亿美元的净流入形成鲜明对比。
U.S. Equity Funds Post First Weekly Outflow in Three Weeks, Losing $6.65 Billion
U.S. equity funds recorded their first weekly outflow in three weeks in the week ended October 28, with investors withdrawing a net $6.65 billion — the first outflow since October 7 — according to LSEG Lipper data. Caution grew ahead of major super intelligence hyperscalers' earnings amid concerns about the rising cost of their build-outs.
By size, large-cap funds recorded $3.8 billion of outflows, partly reversing the prior week's $8.72 billion of inflows. Mid-cap funds shed $2.11 billion, small-cap funds $832 million and multi-cap funds $303 million.
Sector funds bucked the trend with $3.52 billion of net inflows, the largest in three weeks, driven largely by $4.54 billion of net purchases of technology funds. Financial and healthcare sector funds saw outflows of $713 million and $701 million, respectively. During the week Microsoft reported a strong cash-flow beat and a robust cloud outlook, while Alphabet and Amazon disappointed investors with their results.
U.S. bond funds attracted $2.04 billion, recovering from net sales of $969 million the prior week. Municipal debt funds, general domestic taxable fixed-income funds and inflation-protected funds recorded net purchases of $1.74 billion, $1.31 billion and $1.08 billion, while short- to intermediate-term government and Treasury funds and short- to intermediate-term investment-grade funds saw outflows of $2.48 billion and $1.59 billion.
Money market funds recorded net outflows of $47.66 billion, following roughly $14.97 billion of inflows the previous week.
