Why 21 DTE May Change How You Manage Options

Capital Allocation & Portfolio Volatility: Strangles & Short Puts – A Detailed Analysis

Key Concepts:

• Capital Allocation: The percentage of a portfolio’s capital dedicated to a specific strategy or asset.
• Volatility Control: Managing the degree of price fluctuation in a portfolio.
• 21 DTE (Days to Expiration): Exiting options trades 21 days before their expiration date.
• Strangles: An options strategy involving buying both a call and a put option with the same expiration date but different strike prices.
• Naked Puts (Short Puts): Selling put options without owning the underlying asset.
• Standard Deviation: A statistical measure of volatility, representing the dispersion of returns around the average.
• Max Profit: The maximum potential profit from an options strategy.
• Bull Market: A period of sustained increase in asset prices.

I. Introduction & Recap of Strangle Study

The presentation builds upon a previous analysis of strangle strategies, demonstrating how changes in capital allocation impact portfolio volatility. The initial study focused on strangles exited at 21 days to expiration (DTE) as a method for optimal volatility control, details of which can be found in the “Options Drive” from earlier that day. The initial capital allocation was tested at 25% and then increased to 35% of the portfolio. Increasing capital allocation to 35% showed improvement in average daily return, but also resulted in increased volatility. Specifically, a 50% winner saw better performance with increased capital, but at the cost of higher volatility.

II. Short Naked Put Analysis – Methodology

A subsequent study was conducted on short naked puts (specifically, selling 20 delta SPY puts with 45 DTE). Three scenarios were analyzed:

1. Held to Expiration: Maintaining the position until the options expired.
2. Managed at 50% of Max Profit: Closing the position when 50% of the maximum potential profit was realized.
3. Exited at 21 DTE: Closing the position 21 days before expiration.

The goal was to determine if similar results regarding volatility control would be observed as with the strangle study.

III. Short Put Results – Volatility Comparison

The analysis revealed that exiting short put positions at 21 DTE maintained a similar level of volatility compared to the strangle study. Other approaches (holding to expiration and managing at 50% max profit) resulted in increased volatility. Interestingly, despite the expectation that naked puts would perform better in a rising market from a volatility perspective, the difference wasn’t as significant as anticipated. The 21 DTE exit consistently smoothed out profit and loss (P&L).

Quote: “If you’re not taking my word for it and you’re not taking Jamal’s word for it, then take a look at these studies and and really that’s the way to go.” – Speaker emphasizing the importance of data-driven decision making.

IV. Impact of the Bull Market & Strategic Timing

The decade-long bull market influenced the performance of managing winners in short put strategies, boosting returns and outperforming other approaches. However, the consistent finding across both studies (strangles and puts) was that exiting at 21 DTE was the most effective method for controlling volatility.

Quote: “Decade long bull market scares me just as just as much.” – Speaker highlighting the potential for market correction after a prolonged uptrend.

The speakers acknowledged the current market conditions, noting the S&P 500 trading around 6806 and the NASDAQ experiencing a sell-off around 300 points. Despite this, volatility remained relatively contained around 46.

V. Capital Allocation with Short Puts – Further Analysis

The study then mirrored the strangle analysis by increasing committed capital usage from 25% to 35% within the same portfolio, applying it to the short put strategy. The results again demonstrated that exiting at 21 DTE yielded the best results for maintaining volatility within a tight range. Holding positions to expiration or managing at 50% of max profit resulted in significantly higher volatility increases, even exceeding those observed with strangles.

VI. Profitability vs. Volatility – The Trade-off

Increasing capital allocation to 35% led to a larger increase in both profitability and volatility when managing winners. The speakers emphasized the importance of discipline and a mechanical approach to trading, particularly when increasing position size. Waiting for a 50% winner resulted in substantially higher volatility, with daily moves potentially causing significant emotional stress.

Quote: “You got to be more mechanical like is really what this is getting at here.” – Speaker stressing the need for a systematic approach to trading.

VII. Key Takeaways & Conclusion

The presentation concluded with the following key takeaways:

• 21 DTE is Optimal: Exiting both strangle and put positions at 21 DTE consistently proved to be the best approach for controlling volatility, regardless of capital allocation.
• Managing Winners in Bull Markets: Managing winners provides stronger returns in bull markets.
• Discipline & Mechanical Approach: A disciplined, mechanical approach to trading is crucial, especially when increasing capital allocation.

The speakers reiterated that the 21-day exit strategy effectively smooths out P&L and allows traders to remain in the market without excessive risk. The data presented strongly supports the idea that a consistent, time-based exit strategy is a key component of successful options trading and volatility management.

Technical Terms Explained:

• Delta: A measure of an option's sensitivity to changes in the price of the underlying asset. A delta of 20 means the option price is expected to move $0.20 for every $1 move in the underlying asset.
• DTE (Days to Expiration): The number of calendar days remaining until an option contract expires.
• SPY: The ticker symbol for the SPDR S&P 500 ETF Trust, a popular exchange-traded fund that tracks the S&P 500 index.
• Max Profit (for a Short Put): The maximum profit a seller can make on a short put option, which is limited to the premium received.
