The market is at a "critical breakout point"! Goldman Sachs reveals: This week, institutional selling and shorting of U.S. stocks reached "historic levels."

```

An unprecedented wave of institutional selling is pushing U.S. stocks to a dangerous tipping point—it could either trigger a short squeeze if geopolitical tensions ease, or lead to deeper declines should the situation continue to deteriorate.

Goldman Sachs’ futures desk data shows that from March 3 to 10, asset management institutions’ net selling of S&P 500 futures reached $36.2 billion, the largest single-week reduction in more than a decade by nominal value. Goldman’s Robert Quinn directly blames the Iran war and the accompanying surge in oil prices, calling them the immediate catalysts for this round of rapid institutional exits.

Meanwhile, data from Goldman Sachs’ ETF trading desk shows that on Thursday, short positions in U.S.-listed ETFs increased by 10% in a single day, the second-largest daily increase in Goldman’s history. The overall short exposure of macro products has risen to the highest level since September 2022. With both futures selling and ETF shorting advancing in parallel, the market’s extreme stress is clearly evident.

However, the ultimate outcome of this battle largely depends on geopolitical developments. Goldman’s U.S. trading chief John Flood noted that investors still hope that the broad uncertainty caused by the Iran war will soon dissipate, but the window for this hope is closing—if there is no positive progress in the next two weeks, “from the perspective of stock indices, we will be facing problems.”

Institutions net sell $36.2 billion, S&P futures see largest weekly sell-off in ten years

Goldman’s futures desk data reveals the historical anomaly in institutional behavior this week. From March 3 to 10, asset managers net sold $36.2 billion in S&P 500 futures, exceeding any single-week sell-off over the past decade by nominal amount.

Robert Quinn’s report pinpoints the core driving force behind this rapid retreat: the intensifying Iran war and the simultaneous surge in oil prices resonated, sparking a rapid capital exodus by institutions. Notably, while institutions aggressively sold off futures, other non-dealer market participants showed divided attitudes—leveraged funds, in the volatile commodities market, remained relatively resilient and did not take equally strong directional bets.

Record ETF shorting, short exposure climbs to three-year high

During the same week of historic futures selling, Goldman’s ETF desk recorded stunning data as well. On Thursday alone, U.S.-listed ETF short positions in Goldman’s prime brokerage accounts surged by 10%, the second-largest daily increase in Goldman’s history, only behind the 16% recorded on April 2, 2025.

This resonance between futures and ETF shorts has pushed the overall short exposure of macro products to the peak since September 2022. This comparison is particularly noteworthy—April 2025 was one of the most intense policy-impact days for the market so far, and the current ETF shorting intensity is already close to that level, reflecting the current market’s suppressed sentiment.

Short squeeze or crash: both lurk around the tipping point

Despite the unprecedented scale of this round of reductions, Goldman reminds clients that institutional investors’ net long positions still sit at the 71st percentile over the past two years, not fully cleared. This structural feature means the market is currently in a highly sensitive state of balance and the direction is not yet finalized.

John Flood notes that large-scale de-risking (as ETF shorting surges, overall leverage has not fully contracted) overlaps with rapidly worsening sentiment—the sentiment indicators track institutional S&P futures positions almost point-for-point—meaning a single trigger could rapidly ignite a violent short squeeze, sending the “weak hand” institutions who previously sold scrambling to chase gains in a perfect storm.

These two dramatically different outcomes both point to the same key variable: the Iran war’s trajectory. John Flood says investors are still hoping that the wide uncertainty sparked by the conflict will dissipate soon. Once the situation signals easing, the accumulated massive short positions could fuel a market surge; but the longer the market waits, the greater the fragility, eventually breaching the tipping point and triggering an unavoidable downward shock.

“The market hopes for some signs of a solution in the next two weeks,” John Flood warns:

“But if this situation drags on with no positive progress, then from the perspective of stock indices, we’ll be facing problems.”
