The Stock Market's Decline May Still Have Much Further To Unwind

The S&P 500's current decline is poised to continue, driven by tightening market liquidity conditions, as evidenced by a rising Treasury General Account and falling Fed reserves that are unlikely to improve significantly by year-end. Concurrently, the unwind of the volatility dispersion trade, characterized by a declining S&P 500 dispersion index and rising implied correlations, suggests further downward pressure as constituent volatility falls and index-level volatility is expected to rise. This confluence of factors, alongside historically low realized volatility, creates a significant bearish setup for equities.

Analysis

The S&P 500's current decline is attributed to a significant tightening of market liquidity and the unwind of volatility dispersion, suggesting further downside potential. Liquidity conditions have deteriorated as the Treasury General Account (TGA) has risen above $850 billion, currently at $942 billion, while reserves held at the Fed have fallen below $2.9 trillion to $2.85 trillion. Despite a projected $90 billion increase in reserves by year-end, this is deemed insufficient to alter the liquidity landscape, with the TGA targeting $850 billion.

Concurrently, the volatility dispersion trade is unwinding, evidenced by the S&P 500 dispersion index falling from 40.6 to 35.6, yet remaining elevated. Implied correlations have risen to 17, and the spread between the dispersion index and 3-month implied correlation is a very wide 18.5. This dynamic implies constituent volatility is declining while index-level volatility is set to rise, contributing to S&P 500 weakness.

Furthermore, the spread between constituent-level implied volatility and the S&P VIX Index is 20 points, indicating high individual stock volatility versus low index volatility. Three-month realized volatility, currently near 8, is historically very low, having only been lower in periods preceding sharp S&P 500 declines (Dec 2017, Oct 2018, Jan 2020). This confluence of tightening liquidity, stretched dispersion, and record-low realized volatility creates a significant bearish setup for equities.

Key Decisions for Investors

• Investors should consider increasing short exposure or hedging existing long positions in broad market indices like SPY, given the confluence of tightening liquidity and unwinding volatility dispersion.
• Monitor key liquidity indicators such as the Treasury General Account balance and Fed reserves, alongside volatility metrics like the S&P 500 dispersion index and implied correlation, for signs of market stabilization or further deterioration.
• Re-evaluate portfolio risk exposure and potentially allocate towards defensive assets or strategies that benefit from increased market volatility and declining equity prices, as the current environment suggests continued downside pressure.
