A bad month rarely breaks a fund. Losing control over when and how it sells often does. This Insight looks at what this year’s hedge fund difficulties have in common, the structural questions investors can ask before stress arrives, and where a rules-based, one-decision-a-day process sits against them.
A difficult Thursday
On Thursday, 5 November 2026, the S&P 500 fell 4.36% and the Nasdaq Composite fell 5.52%, closing more than 10% below its record and entering correction territory. For all three major US equity averages it was the worst session since April 2025. Selling was heaviest in semiconductor and AI-infrastructure stocks, but every one of the eleven S&P 500 sectors closed lower.
The following day, The Wall Street Journal reported that hedge funds were cutting positions and staff as the selloff deepened. How much of Thursday’s decline came from forced selling will only become clear once positioning data is published. What is already visible is a pattern that has been building through 2026, and it says more about funding structures than about returns.
Losses are not the warning sign
Most hedge funds that lost money in October did so in an ordinary way. Several of the largest multi-manager and equity firms reported monthly declines of roughly -2% to -5%. Losses of that size are uncomfortable, yet, on their own, they are not evidence of distress.
The cases that became serious this year share a different feature: at some point, a party other than the portfolio manager began to set the timing of sales.
- Lenders. A large credit-focused fund, concentrated in a small number of troubled borrowers and running leverage, was reported in early November to be down more than 26% for the year, facing bank margin calls, and selling more than US$2 billion in face value of debt within a week. The manager said it was “operating normally”.
- Liquidity, in a single month. In July, a concentrated equity fund with leveraged positions in AI-related stocks lost 67% in one month and sold most of its listed equity portfolio as liquidity deteriorated. Even after that loss, it was reported to be up for the year, thanks to large gains in earlier months.
- The redemption queue. A long-established flagship fund changed its exit arrangements in July. Departing investors would receive an initial cash payment, with the remaining assets moved into a vehicle that sells them over time. Its reported first-half return was only −0.5%. The difficulty lay in the timetable of cash, not in the return.
- The business model. Several managers closed after years of returns that disappointed investors or no longer covered the cost of talent and infrastructure. One quantitative firm closed after its founder concluded that its models “no longer fit the market”. An equity manager wound down despite annualized returns of about 4% since launch. In one multi-strategy closure, wind-down costs passed through to investors were estimated at 10% to 15% of net asset value.
These distinctions matter because headlines tend to compress them. Positive cumulative performance can still fail to sustain a business. A closure is not insolvency, and a lawsuit or a regulatory inquiry is not a finding of wrongdoing.
Why stress travels
The International Monetary Fund (IMF) devoted a chapter of its October 2026 Global Financial Stability Report to hedge funds. It estimates that hedge fund gross assets reached about US$13 trillion in early 2026, up from about US$4 trillion in 2013, with much of that growth financed through leverage, including synthetic leverage obtained through derivatives.
In normal markets, the IMF notes, hedge funds add liquidity and help prices adjust. When volatility rises or financing tightens, margin calls can force them to sell, and they move from providing liquidity to absorbing it. By the IMF’s measure, the stocks most widely held by hedge funds are 10 percentage points more volatile than the least crowded ones, and losses at hedge funds can spill over to the prime brokers that finance them.
There is a serious counter-argument. The Managed Funds Association, the industry’s trade body, has published a review concluding that over nearly three decades of market stress, there is little evidence of hedge funds posing systemic risk. Both views can hold at the same time. The industry as a whole may be resilient while individual funds that combine leverage, concentration, and mismatched liquidity remain fragile. The 2026 cases fit the second description far better than any story of industry-wide failure.
Five questions worth asking before stress arrives
For allocators, the useful questions concern structure rather than last month’s return.
Identify every party with the right to demand cash: prime brokers, other lenders, and investors with near-term redemption rights.
A fund with monthly dealing that holds assets taking quarters to sell carries a mismatch that only becomes visible under pressure.
Positions shared with many other leveraged holders tend to fall together.
A fund that cuts exposure because its process tells it to, behaves differently from one that cuts exposure because a margin call has arrived.
Pass-through expense structures can transfer closure costs to the investors who remain.
For an investor already exposed to a fund under pressure, the next documents to request are the latest net asset value from the administrator, the fund’s financing and liquidity terms, any redemption notices, and the distribution schedule if a wind-down has begun.
How Demeter’s process sits against these questions
Demeter’s Dual-State strategy was not built in response to this year’s events, and it is not immune to them. Its design does, however, answer several of the questions above in a specific way.
- One decision a day, set by consistent rules. At 3:59 pm New York Time on each trading day, the algorithm decides whether to hold index exposure for the next session and, if so, how much leverage to apply. The decision horizon is one trading day.
- Exchange-traded index markets. In the Active State, exposure is taken through futures and/or options on the S&P 500 and Nasdaq indices. The strategy holds no single-company positions and no credit instruments in its equity allocation.
- Leverage within a defined ceiling. Futures positions are marked to market every day and carry margin requirements like any other leveraged position. Using listed index futures changes the form of that risk; it does not remove it. This said, the Dual State Strategy has historically applied a modest degree of leverage (between 1.5x to 3x) and only on approximately ten percent of trading days that the Active State takes exposure.
- A Defensive State that holds no index exposure. On roughly half of all trading days, the signal holds no position in the indices.
- Index concentration. The November selloff was led by semiconductor and AI-related stocks, which carry heavy weights in both indices the strategy trades. When the strategy is in the Active State, its exposure includes them. When an entire index moves, the Active State carries a 1:1 exposure provided no leverage has been applied.
The distinction that matters now
The question many investors are asking this autumn is whether hedge funds are in trouble. A more useful question is where the decision to sell is made in each fund they own: inside the investment process, with a lender, or in the redemption queue. Funds whose exits are set by their own rules can still lose money, sometimes a great deal. What they retain is control over timing, which is usually the first thing a stressed fund loses.
In the case of Demeter’s Dual State Strategy, historical exposure to equities markets has been just over 52% of the time. Nearly half of all trading days, the Dual State Strategy is in the Defensive State. Long term investing is the best way to deliver compounding returns and endure markets that move against a manager. In Demeter’s case, the strategy delivered a positive month in October, and the fund has every opportunity to do so again in November in spite the Nov 5th sell off. Past performance is no guarantee of future performance, so every allocator must consider their individual exposure across their portfolio. We remain confident our strategy is performing as designed and the risk controls employed daily continue to meet expectations.
