Goldman Sachs: CTAs maxed out on U.S. equities, downside risk looms

Goldman Sachs reports that trend-following investors (CTAs) purchased $12.6 billion in US equities in August, pushing their exposure to the 100th percentile, indicating they are 'maxed out.' This significant positioning suggests less supportive equity flows for September, a historically weak month. Goldman further warns of asymmetric downside risk, with potential CTA selling of $73.7 billion in US equities if market sentiment deteriorates.

Analysis

According to analysis from Goldman Sachs, trend-following investors (CTAs) have reached maximum exposure to US equities following net purchases of $12.6 billion in August. This has elevated their positioning to the 100th percentile, indicating that a significant source of systematic buying support for the market is now exhausted. The situation presents a risk profile that is asymmetrically skewed to the downside, particularly heading into September, a historically weak month for equities. A negative market shift could trigger substantial deleveraging from this cohort, with Goldman Sachs estimating potential CTA selling pressure of up to $73.7 billion in US equities, which could significantly amplify any market downturn.

Key Decisions for Investors

• Given the 'maxed out' positioning of CTAs and the asymmetric downside risk, consider reviewing portfolio hedges and potentially reducing overall equity beta exposure.
• Monitor market technicals and volatility closely, as a break below key support levels could trigger the estimated $73.7 billion in systematic selling, exacerbating downward price momentum.
• Exercise caution on new long positions that rely heavily on continued market momentum, as a primary driver of supportive inflows appears to be depleted for the near term.
