Leveraged contracts linked to chip stocks suffered a weekend liquidation cascade while the underlying equity markets were closed, exposing a fault line in round-the-clock trading: positions can be forced shut even when the shares they reference are not trading.
About $51.6 million in positions tied to semiconductor stocks and funds were liquidated between 21:22 and 21:32 UTC on October 17, according to CoinGlass figures reported by CoinDesk. Roughly $38 million involved traders positioned for higher prices. The figures describe leveraged derivatives, rather than a matching amount of shares sold on a stock exchange.
Contracts linked to SOXL, SanDisk and SK Hynix were among those affected. SOXL itself is a leveraged semiconductor fund, adding another distinction investors need to make between exposure to an individual company, a fund and a perpetual contract referencing either one.
Stock exposure can trade after the stock market shuts
Perpetual futures let a trader take a directional position without buying the underlying security. Unlike a conventional dated future, the contract has no scheduled expiry. Its trading, margin and funding arrangements determine how the position behaves.
Trade XYZ’s documentation identifies stocks among the perpetual markets it deploys on Hyperliquid. Such products can continue trading when the conventional market supplying the most familiar share-price reference is closed. That extends access, but it also leaves the derivative market responding to orders without a fresh cash-market trade to anchor expectations.
The weekend move should therefore not be described as a Saturday crash in the actual shares. An investor holding a stock-linked derivative has a different position from a shareholder. The contract’s price, margin requirements and liquidation rules can affect that investor before the stock market reopens.
Forced closures can amplify a move
Leverage allows a position to exceed the capital initially committed to it. When losses reduce the remaining margin below the venue’s requirements, the position can be liquidated. A trader can consequently lose exposure before a later rebound occurs.
That mechanism creates a feedback risk. A price decline can trigger the closure of positions betting on a rise, adding further pressure in the same direction. The extent depends on the venue’s rules, available liquidity and the positions outstanding; the reported liquidation total alone does not establish each step of the sequence.
Our guide to perpetual futures and funding rates explains how these contracts differ from simply owning an asset. Funding payments, margin and the reference used to assess a position all matter alongside the direction of the underlying investment.
The reopening is a comparison, not a guaranteed recovery
When the relevant stock markets resume trading, new share prices will provide another reference for assessing the weekend contracts. That does not promise that the shares will follow the derivatives or that the derivatives will return to an earlier level.
Nor does a later convergence undo a liquidation that has already occurred. For a leveraged trader, the path taken by prices can matter as much as where they eventually settle. A position closed during a short disturbance no longer participates in the subsequent move.
The episode shows a practical limit to treating continuous availability as equivalent to continuous underlying liquidity. Stock-linked crypto contracts can stay open through the weekend, while the conventional market, its participants and its price-discovery process follow a different timetable.
