According to Odaily Planet Daily, Goldman Sachs' institutional brokerage noted that as the stock market's upward momentum cooled, hedge funds saw the largest increase in short positions across U.S.-listed ETFs in nearly four years last month.

Vincent Lin, co-head of Goldman Sachs Prime Insights & Analytics, stated that short selling in U.S.-listed ETFs increased by 14.6% in December, marking the largest monthly increase since February 2021.

Macro products such as indices and exchange-traded funds saw net buying in the first half of the month, but selling activity increased as the year approached its end. The most shorted market areas include large and small-cap stocks, healthcare, and corporate bond ETFs.
