U.S. stock market selling pressure is approaching historical extremes, but conditions for a potential rebound are quietly building. Data from Goldman Sachs' prime brokerage desk indicates that hedge funds have reduced their global equity exposure for six consecutive weeks, with the net selling volume ranking as the third largest over the past decade, nearing peak levels seen during the COVID-19 market crash. Concurrently, Goldman Sachs analysts note that trend-following systematic investors, or Commodity Trading Advisors (CTAs), have sold approximately $190 billion in equities over the past month. They currently hold a net short position of around $50 billion in global stocks, but their selling momentum appears to be waning. Goldman Sachs believes these extreme positioning levels are creating asymmetric upside potential for the market. The firm estimates that CTAs will transition to being net buyers over the next month, regardless of market direction. Simultaneously, pension fund rebalancing purchases are expected to enter the market at the quarter-end, and a negative Gamma exposure of roughly $7 billion held by options market makers is set to expire and dissipate by month-end. This convergence could alleviate multiple technical pressures simultaneously. Hedge fund selling is approaching a potential "capitulation" signal. Goldman Sachs' prime brokerage team, in their weekly market data review up to March 26, reported that the latest round of hedge fund de-risking was broad-based, with net selling observed across major regions. In European markets, short exposure in macro products rose to 11%, reaching a ten-year high. In the U.S. market, the Goldman team suggested in a separate report that "some signs of capitulation are beginning to emerge," implying that fund pessimism may be nearing a peak. Calculated on a rolling six-week basis, the net selling of U.S. stocks is the third highest in the past ten years, approaching levels seen during the COVID sell-off, though still below the peak observed during the "Tax Day" tariff impact in April 2025. From a market performance perspective, what was initially seen as a relatively mild pullback is deepening. The Nasdaq 100 index has declined more than 10% from its peak, officially entering a technical correction. The S&P 500 is also nearing that same threshold. Meanwhile, the Europe Stoxx 600 index has fallen nearly 9% since March, on track for its worst monthly performance in six years. The selling pressure from CTAs is showing signs of exhaustion, highlighting the market's asymmetric rebound potential. The shift in positioning by systematic investors represents another critical variable. Goldman Sachs analyst Cullen Morgan pointed out that CTAs have sold approximately $190 billion over the past month and now hold a net short position of about $50 billion in global equities, but their selling momentum is fading. "Systematic investors are running out of ammunition," Morgan wrote. "The asymmetry points to the upside—we estimate that CTAs will be buyers under any scenario over the next month." Simultaneously, Goldman Sachs models indicate that pension funds are poised to buy equities for quarter-end rebalancing. Furthermore, the approximately $7 billion negative Gamma exposure held by options market makers will expire at month-end, automatically removing a persistent technical headwind. The combination of these factors forms a potential foundation for a short-term technical rebound. Geopolitical tensions remain the most significant variable, and Goldman Sachs refrains from declaring a definitive market bottom. Despite extreme technical signals, the firm maintains a cautious stance on whether the market has truly found a floor. Goldman's Brian Garrett wrote in a client report, "It feels like we're closer to the end than the beginning, but this game doesn't have classic 'innings'." Garrett noted that no market participant currently has a clear timeline for the conflict involving Iran, and de-escalation requires consensus among multiple parties—a sign that is not yet evident. "While, as sell-side analysts, 'calling the bottom' successfully is a pleasant thing—and many have tried—honestly, we are not there yet," Garrett stated. Goldman Sachs' overall assessment is that extreme positioning and the dissipation of technical pressures provide the market with asymmetric upside potential, but a genuine trend reversal still depends on a substantive easing of geopolitical tensions.
