Goldman Sachs' prime brokerage unit says hedge funds bought US equities last
week at the fastest pace in six months as the S&P 500 extended its record run.
Goldman traders said flows were driven by long buying in index products and ETFs
and by short covering. US-listed ETF short positions fell for a second week,
down 0.6%. Ongoing AI-infrastructure investment and better-than-expected
earnings supported the rally. The S&P 500 has risen nine straight weeks, the
longest streak since 2023; the Nasdaq-100 is up more than 20% YTD.
