Bank of America analysts report that systematic trading strategies, including CTA and risk-parity funds, currently possess only $9 billion in buying capacity. In the event of a market downturn, these same algorithms could be forced to sell up to $163 billion in equities.
This creates an 18-to-1 sell-to-buy ratio, indicating a significant imbalance in market positioning. Data from Deutsche Bank confirms that equity allocations for volatility-control funds have reached the 100th relative percentile, marking an absolute ceiling for exposure.
The Bull and Bear Indicator, managed by strategist Michael Hartnett, has signaled a sell since May 2026. In early August, the indicator reached a reading of 9.7, the highest level recorded since 2021.
Market liquidity is further constrained by the seasonal blackout period for corporate buybacks, as companies pause repurchase programs ahead of earnings reports. Historically, September is a weak month for US stocks, and current conditions suggest a lack of downside shock absorbers.
