0DTE Volatility Expands With New 24-Hour Trading for Russell 2000 Index Options

• Cboe Global Markets expanded trading hours for Russell 2000 (RUT) and RUTW options to nearly 24/7, five days a week, enabling global investors to manage U.S. small-cap exposure during local business hours according to recent reports.
• In January 2026, 0DTE options accounted for 23% of RUT activity, reflecting growing demand for short-dated strategies amid rising market volatility and dispersion as data shows.
• The expansion complements Cboe's existing 24/7 trading model for S&P 500 (SPX) and VIX options, enhancing the ability of investors to implement a diverse range of strategies across time zones and market conditions according to Cboe.

Cboe Global Markets has expanded Russell 2000 (RUT) and RUTW options trading hours to nearly 24/7, five days a week, in a move designed to accommodate global investors seeking to manage U.S. small-cap equity exposure during local business hours as reported. This development is part of a broader trend toward dynamic, short-term trading strategies, particularly in the context of 0DTE options, which allow investors to execute trades that expire on the same day they are traded according to market analysis.

The expansion supports diverse strategies for both retail and institutional investors, including hedging, yield generation, and targeted market positioning. The rise in demand for these options is linked to heightened market volatility and dispersion, which have made short-term strategies increasingly attractive as research indicates.

The move also enhances liquidity and reduces execution risk, particularly for investors in Europe and Asia-Pacific, who can now engage with U.S. small-cap markets during their local daytime hours according to market data. This aligns with Cboe's broader initiative to provide advanced trading tools and expand access to U.S. equity options markets globally as Cboe stated.

Why Is 0DTE Volatility Expanding?

The growing popularity of 0DTE options is driven by their unique characteristics: they offer precise timing and responsiveness in fast-moving market environments according to market analysis. These contracts allow investors to react swiftly to market movements and manage risk with minimal exposure. As a result, 0DTE options have become a favored tool for investors seeking to hedge or capitalize on short-term market fluctuations as reported.

Cboe's decision to extend trading hours reflects the demand from global markets for greater flexibility in executing these strategies according to Cboe. The firm has noted a 27% increase in trading volume during its Global Trading Hours session in 2025, underscoring the increasing relevance of 24/7 trading models as Cboe reported.

How Does This Affect Investors?

The expansion of RUT options to 24/7 trading hours provides global investors with more precise tools for managing risk and implementing strategies in small-cap equity markets as market data shows. For example, investors in Asia and Europe can now engage in RUT options during their local daytime hours, reducing the reliance on after-hours or pre-market sessions according to analysts.

The 0DTE options have also become a key instrument for generating yield and executing dispersion trades, particularly in a market landscape where traditional large-cap dominance is shifting as reported. This development is particularly relevant for emerging markets, where access to U.S. small-cap options has historically been limited according to market research.

What Happens Next?

Cboe is also working on other innovations, including binary event contracts that could offer a new class of financial instruments under SEC regulations according to Cboe. These contracts, which enable betting on event outcomes, are expected to launch by the second quarter of 2026, pending regulatory approval and platform readiness as stated.

Additionally, regulatory reform proposals are being considered that aim to shift the Options Regulatory Fee (ORF) model toward a more equitable system where exchanges only charge fees on transactions occurring on their own markets according to Bloomberg. This could further impact the cost structure and efficiency of options trading, including for 0DTE strategies.

The growing institutional interest in prediction markets is also noteworthy, with at least three ETF providers proposing funds tied to election outcomes as reported. If approved, these could signal a broader acceptance of event-driven and binary contracts in mainstream investing.
