MalltonAsset’s market team sees the options market entering a new phase: not because derivatives are “new,” but because time inside the options complex has been compressed. Same-day expirations (0DTE) have moved from a niche tool to a daily driver for hedging and speculation, and that shift is changing how liquidity behaves, how volatility is expressed, and how risk travels through a trading session.
Cboe’s own volume reporting underscores the scale. Across Cboe’s U.S. options exchanges, 2025 total volume reached 4.6 billion contracts with an average daily volume (ADV) of 18.4 million, extending a multi-year streak of record activity. What MalltonAsset takes from those numbers is not simply “more trading,” but a market structure that is increasingly short-dated, event-driven, and reflexive—especially around major data releases, policy headlines, and intraday momentum.
Why 0DTE is the structural story
0DTE (zero-days-to-expiry) options are contracts that expire at the end of the current trading day—a definition Cboe highlights directly in its educational materials. By design, that means very high sensitivity to small underlying moves and rapid time decay, making 0DTE a powerful instrument for precise intraday expression.
Evidence of adoption is increasingly hard to ignore. Cboe’s November 2025 volume report cited a new SPX 0DTE ADV record of 2.8 million contracts, alongside a broader SPX options ADV record of 4.6 million. Separate market reporting has described 0DTE as representing around ~60% of S&P 500 options volume in late 2025, a level that would have been difficult to imagine just a few years ago.
MalltonAsset’s view: when a market migrates toward same-day maturities, its “center of gravity” shifts from multi-week narratives to hour-by-hour positioning.
Liquidity looks deeper—until it doesn’t
In normal conditions, the rise of shorter expiries can create the appearance of thicker liquidity: tighter spreads, more prints, and constant two-way flow. But MalltonAsset flags a critical nuance: short-dated flow can also make liquidity conditional. It’s present when the tape is orderly, and it can thin quickly when price accelerates.
That matters because 0DTE concentrates risk in the parts of a session where hedging needs change fastest. When positioning is dense near popular strikes, small moves can trigger rapid adjustments in exposure. Some academic and practitioner research has focused on how large 0DTE volumes can amplify the importance of “gamma” and hedging behavior into the close.
MalltonAsset does not frame this as “good” or “bad.” It’s simply the operating environment: liquidity is dynamic, and the options market is increasingly a real-time risk transfer machine.
Volatility is being expressed differently
Another implication: the relationship between realized moves and implied pricing can feel less stable. In a 0DTE-heavy world, traders are often buying or selling exposure to today’s range rather than next month’s uncertainty. The result can be:
- Sharper intraday volatility regimes (quiet mornings that suddenly break into fast tape).
- More importance on event timing (a single headline can matter more than a full day of drift).
- A stronger role for “volatility-of-volatility” moments, especially when many participants reach for the same short-dated structures.
This is consistent with periods in 2025 when options activity spiked to historic levels on headline risk. Cboe’s industry commentary notes days where total U.S. options volume exceeded 100 million contracts, and even referenced sessions surpassing 110 million amid tariff and policy uncertainty.
What MalltonAsset watches now
Rather than trying to predict every twist, MalltonAsset focuses on repeatable indicators that tend to matter more in short-dated derivatives:
- Concentration near key strikes
When flow piles into a narrow band of strikes, intraday moves can become more mechanical. - Expiration “density” across the week
Daily expirations spread activity across more sessions, reducing the old “single weekly pin” dynamic but increasing the number of days with meaningful expiry effects. - Open interest shifts around event risk
If positioning builds quickly into a known catalyst, the unwind can be just as important as the initial trade. - Volatility skew as a stress signal
Persistent demand for downside protection can reveal hedging pressure even when spot moves appear calm.
Practical risk framing for participants
MalltonAsset’s analysis emphasizes that the options market’s growth does not remove risk—it moves it. A few principles the team repeatedly highlights:
- Defined risk beats undefined hope. Short-dated options can behave like binary instruments when markets jump. Pre-planned sizing and loss limits matter more than “strong conviction.”
- Time diversification is a hedge. Mixing expiries can reduce the chance that a single intraday move dominates outcomes.
- Avoid treating 0DTE as a lottery ticket. Investor education sources frequently stress that same-day options can swing sharply and decay rapidly.
The bottom line
MalltonAsset expects the options market to remain a centerpiece of global risk transfer in 2026—not because participants suddenly became more speculative, but because the market has standardized tools that let them express views and hedges with precision. The key adaptation is mental: when a large share of activity expires today, “market structure” becomes less about long narratives and more about how positioning evolves from open to close.
If 2025 was the year the numbers confirmed the transformation, 2026 is shaping up as the year participants refine playbooks around it—separating robust, repeatable process from the noise of a faster tape.
