22 September 2026

Editor’s Note

Yesterday continued the unfavorable regime for the strategy. Tail volatility kept rising despite only a modest move in the underlying market. Because realized movement remained very limited, short-dated gamma was unable to compensate for the negative effect of higher far-tail volatility.

A further negative factor was the expiration of previously purchased hedges, which also had a meaningful impact on the day’s result.

There also remains a gap between the portfolio value observed intraday in the terminal and the official post-clearing broker result. The terminal showed a materially better picture, but for the public track record we continue to use the official post-clearing broker data.

Together, these factors produced a very weak day. The drawdown is significant and clearly disappointing. However, a substantial part of the negative repricing reflects higher tail volatility in an almost unchanged market rather than realized directional movement in the underlying. We will continue to monitor the volatility surface and assess how persistent this regime proves to be.

Market

Session of 22 September 2026
Technical Analysis

The September 22 session left the S&P 500 essentially unchanged while growth leadership continued inside the Nasdaq. The S&P 500 closed at 7,764.64, effectively flat, while the Nasdaq-100 advanced 0.82%, the Nasdaq Composite gained 0.45%, and the Russell 2000 rose 0.51%.

The index-level structure remains constructive: the S&P 500 is above its 10-, 20-, 50- and 200-day moving averages, with a 14-day RSI of approximately 59.3. However, participation beneath the headline indices remains uneven. A Bloomberg-based breadth reading showed only about 48% of S&P 500 constituents above their 200-day moving averages, while a broad-universe McClellan measure remained negative at −10.15 despite improving from the prior session.

Leadership breadth also remains fragile: across a broad U.S. common-stock universe, 64 securities made new 52-week highs versus 158 new lows. At the same time, volatility eased materially, with VIX falling to 14.21 and VXN to 20.18.

Main technical conclusion: the price trend remains constructive and Nasdaq leadership extended, but medium-term participation still does not fully confirm the strength of the major growth indices.

Fundamental Analysis

The fundamental backdrop remained mixed but broadly stable on September 22. The most supportive development was the continued retreat in oil: Brent traded around $100 and settled near $99.9, easing part of the inflation pressure that had driven Treasury yields sharply higher earlier in September.

The offsetting signal came from monetary policy and regional activity. The Richmond Fed Manufacturing Index fell to −2 from 4, with shipments at −5 and new orders at −6. At the same time, Richmond Fed President Thomas Barkin said economic conditions appeared to be firming and emphasized that inflation risks still outweighed employment risks.

Credit conditions remain calm: broad high-yield spreads were around 2.68%, while the HYG/LQD ratio remained in a tight, risk-on regime. Equity valuation is no longer extreme relative to recent history, but the S&P 500 still trades around 20 times forward earnings, leaving valuation sensitive to Treasury yields near 5%.

Main fundamental conclusion: lower oil and calm credit conditions are supportive, but restrictive policy, a near-5% 10-year Treasury yield and mixed regional growth data keep the fundamental backdrop balanced rather than decisively bullish.

Volatility

Regime. The broad volatility complex normalized on September 22. VIX fell from 14.87 to 14.21 and VIX9D declined to 12.19, while VVIX dropped to 83.17. The previous session’s unusual volatility expansion therefore did not develop into a broad stress regime.

Short versus long volatility. VIX3M declined to 17.61 and VIX6M to 19.79. With spot VIX at 14.21, the term structure remains clearly upward sloping and continues to price more risk in longer maturities than in the immediate horizon.

Surface. Nasdaq volatility remained relatively firm: VXN eased only modestly to 20.18 while QQQ gained 0.81%. SKEW increased from 142.19 to 144.80, indicating some restoration of relative downside-tail pricing. QQQ option activity remained call-heavy in premium terms, with calls accounting for 78% of approximately $1.38 billion in option premium turnover.

Principal warning. Broad volatility is calm, but Nasdaq implied volatility remains elevated relative to VIX and realized volatility. The market has normalized from Monday’s upside-volatility shock without fully removing technology-specific convexity demand.
