Systematic equity re-risking of ~$200bn has largely been completed, leaving CTAs with limited room to buy further while Treasury shorts approach capacity. Market focus shifts to downside selling risks and end-of-day rebalancing from leveraged ETFs and option gamma.

Key Takeaways

  • 1.CTA equity buying momentum is slowing following a ~$200bn systematic re-risking since April lows, with limited scope for incremental long accumulation.
  • 2.CTA shorts in US Treasury futures are approaching capacity, particularly in 2yr and 5yr contracts, though some room remains in the 10yr bucket.
  • 3.SPX option gamma remains meaningfully long at $5.2bn (85th percentile), which could flip materially negative on a 5% market move.
