Every weekday is expiration day in the world of 0DTE options trading. This relatively new phenomenon has caught the attention of financial news followers and policymakers alike. Zero-days-to-expiration (0DTE) options refer to options trades that are executed on the same day the options expire. This article delves into the rise of 0DTE options, their risks, and whether they are worth the hype.
The Rise of 0DTE Options
Key Points
- Between 2016 and 2023, 0DTE trading increased from 5% to 43% of total SPX options volume.
- In 2023, 95% of 0DTE volume involved defined-risk strategies.
- Exchange data shows minimal impact on intraday volatility from 0DTE options.
Historical Context
For as long as there have been listed options, expiration has been a fundamental aspect. Options are either exercised if they are in the money or expire worthless if they are out of the money. However, with the advent of electronic trading, reduced commissions, and tighter bid-ask spreads, traders have increasingly favored short-term options strategies for hedging or speculation.
Evolution of Expiration Dates
Initially, most listed options had a single expiration date each month (the third Friday). In 2005, the introduction of SPX weekly options by Cboe Global Markets (CBOE) changed the landscape. Over the years, more frequent expiration dates were added, including Monday and Wednesday expirations in 2016, and eventually filling in the entire trading week in 2022. This expansion led to the surge in 0DTE options trading.
Popular 0DTE Options
- S&P 500 Index (SPX): Cash-settled options based on the index’s closing price.
- S&P 500 SPDR ETF Trust (SPY): Options on a physically settled ETF.
- Nasdaq-100 Index (NDX): Cash-settled options on the index.
- Invesco QQQ Trust (QQQ): Physically settled ETF options on the Nasdaq-100.
Understanding 0DTE Options
0DTE options trading targets specific events like economic data releases or earnings reports. This has led to significant growth in 0DTE volume, particularly in SPX options. Between 2016 and 2023, the average daily volume in SPX options increased by 170%, with 0DTE trading rising from 5% to 43% of total volume.
Trading Strategies
Contrary to media portrayal, 0DTE trading is not dominated by high-risk gamblers. Most 0DTE traders use complex, defined-risk strategies with a sophisticated understanding of risk metrics (greeks). A popular strategy involves selling call and put vertical spreads to capture time premium. Many traders employ balanced strategies, such as iron condors, by selling out-of-the-money spreads on both sides of the market.
Risks in Trading 0DTE Options
Uncertainty
The primary risk in short-term options trading is uncertainty. Intraday market movements can cause options to go in and out of the money multiple times. This uncertainty is measured by gamma, the rate of change of delta (an option’s sensitivity to price changes in the underlying asset).
Assignment Risk
For cash-settled indexes like SPX or NDX, there is no intraday assignment risk. However, with American-style, physically settled options or ETFs, there is a risk of being assigned a position in the underlying asset without knowing until after market close. This can be particularly challenging for traders who might unexpectedly end up with a long or short position.
Systemic Risk Concerns
There is concern that 0DTE trading could pose systemic risks by driving market volatility. However, Cboe data suggests that the impact of 0DTE trading on market volatility is minimal. Market maker net directional hedging flows for SPX options represent a small percentage of daily liquidity in S&P 500 futures markets, indicating that 0DTE trading does not significantly influence daily price action.
Conclusion
Should You Trade 0DTE Options?
The ultra-short-term nature of 0DTE options can make trading them a high-risk, high-reward endeavor. Without a detailed risk management plan and a disciplined approach, it is advisable to observe rather than participate in 0DTE trading. For those who trade options, it is often best to liquidate or roll positions before expiration.
Future of 0DTE Options
The future of 0DTE options trading will depend on market conditions and trader behavior. An extended period of high volatility could deter those seeking quick profits, while disciplined traders who adhere to defined risk parameters may continue to find opportunities.
The Bottom Line
0DTE options trading adds another layer of opportunity for experienced traders. However, the risks associated with this strategy require careful consideration and a robust risk management plan. As with any trading strategy, understanding the intricacies and potential pitfalls is crucial for success.
