SKN | JPMorgan Flags Renewed Equity Leverage as a Q4 Risk to Market Positioning

Key Takeaways:

• JPMorgan says elevated equity positioning and leverage have re-emerged, although below the levels seen in June and July.
• The bank’s broader positioning indicator appears to have peaked in September, while leverage through U.S. equity futures has moved close to its highs for the year.
• Margin-account leverage remains JPMorgan’s largest vulnerability, having stayed elevated through the summer deleveraging period.
• Despite these positioning concerns, JPMorgan continues to identify fundamental support for the technology and AI complex, including higher memory prices and stronger hyperscaler capital-spending expectations.

JPMorgan is entering the fourth quarter with a more cautious assessment of market positioning, warning that renewed equity exposure and leverage could create a headwind for stocks. Strategist Nikolaos Panigirtzoglou said several indicators that had eased during the summer deleveraging phase have since rebounded, although the excesses remain below the levels recorded in June and July.

JPMorgan Identifies Leverage as the Central Vulnerability

The bank’s latest assessment places leverage at the center of its Q4 market analysis. JPMorgan noted that leverage through U.S. equity futures has returned close to its highest levels of the year, while its broader positioning indicator appears to have peaked in September after reaching levels previously observed in January and August 2025.

For JPMorgan, the issue is not simply that investors hold substantial equity exposure. The greater concern is the amount of financing and positioning embedded in that exposure. Elevated leverage can make market positioning more sensitive to changes in volatility, liquidity or investor sentiment, potentially amplifying portfolio adjustments.

Margin Accounts Remain JPMorgan’s Key Area of Concern

Among the indicators monitored by the bank, margin-account leverage stands out. JPMorgan said leverage remained very elevated in August and changed little during the summer deleveraging period. That persistence makes margin exposure a more important vulnerability than some of the other positioning measures that have already begun to normalize.

The bank also observed that short interest in SPY has begun to stabilize after reaching a record low in early September. Short positions in semiconductor ETFs have normalized as well, suggesting that much of the earlier short covering may already have taken place. Momentum traders have also started rebuilding long positions in the Nasdaq, Kospi, Taiwan and Nikkei, although not at previous extremes.

JPMorgan Sees Positioning Risk Without Abandoning AI Fundamentals

Importantly, JPMorgan’s assessment does not amount to a broad rejection of the technology and AI investment cycle. The bank continues to see fundamental support for the AI complex, pointing to rising memory prices, higher capital-spending forecasts among hyperscalers and stable AI-computing prices.

This distinction is central to the bank’s view. JPMorgan is separating the underlying earnings and investment case for AI from the increasingly crowded positioning surrounding those assets. In other words, stronger fundamentals do not necessarily eliminate the market sensitivity created by high leverage and concentrated positioning.

What JPMorgan’s Assessment Means for Wealth Structures

For HNWI investors, the relevant signal is therefore portfolio structure rather than a directional market call. JPMorgan’s analysis highlights how leverage, margin exposure and crowded positioning can alter the risk profile of otherwise fundamentally supported assets.

As Q4 progresses, the bank will be watching whether positioning continues to build or begins to unwind. For sophisticated portfolios, that distinction matters because the same equity exposure can carry materially different liquidity and drawdown characteristics depending on how it is financed. JPMorgan’s latest assessment places that interaction between fundamentals, leverage and positioning at the center of its fourth-quarter market framework.
