Since 2022, options traders have experienced one of the most dynamic market environments in recent history. Following the heightened volatility of 2020 and 2021, markets entered a period characterized by rising interest rates, persistent inflation concerns, banking sector stress, and renewed bullish momentum driven by advances in artificial intelligence and technology. Throughout this period, credit spread strategies remained a popular approach for traders seeking defined-risk income opportunities.
A common question among options traders is whether SPY or SPX credit spreads have offered better opportunities since 2022. While both products track the S&P 500 Index, they differ in important ways that can affect trade execution, capital requirements, taxation, and overall strategy performance.
Understanding SPY and SPX
SPY is the SPDR S&P 500 ETF and is one of the most actively traded exchange-traded funds in the world. Its options market provides exceptional liquidity, narrow bid-ask spreads, and expiration dates available throughout the week.
SPX options, on the other hand, are based directly on the S&P 500 Index. Unlike SPY, SPX options are cash settled and cannot be assigned shares of stock. They are also European-style options, meaning they can only be exercised at expiration.
Although both instruments generally move together, their option characteristics can produce meaningful differences for credit spread traders.
Why Credit Spreads Became Popular After 2022
The market environment beginning in 2022 created favorable conditions for many premium-selling strategies.
Several factors contributed:
- Elevated implied volatility during major economic events
- Frequent market pullbacks followed by recoveries
- Large intraday swings that increased option premiums
- Consistent option liquidity across multiple expirations
Higher implied volatility generally increases option premiums, allowing traders to collect larger credits while maintaining similar probabilities of success.
Comparing Profitability
From a directional standpoint, a well-constructed SPY credit spread and an equivalent SPX credit spread typically behave very similarly because both track the S&P 500.
However, profitability is influenced by several practical considerations.
Liquidity
Both SPY and SPX are among the most liquid options markets available.
SPY often provides extremely tight bid-ask spreads for smaller position sizes, while SPX also offers deep institutional liquidity.
For most traders, execution quality is excellent on either product.
Position Size
One SPX contract represents approximately ten SPY option contracts.
For traders with smaller accounts, SPY provides much greater flexibility for scaling positions and managing risk.
Institutional traders often prefer SPX because they can obtain larger market exposure with fewer contracts.
Early Assignment Risk
One significant advantage of SPX is that it eliminates early assignment risk.
SPY options are American-style options and may be exercised before expiration under certain circumstances.
SPX options are European-style and are only exercisable at expiration, simplifying trade management for many premium sellers.
Cash Settlement
SPX options settle entirely in cash.
This means traders do not receive or deliver shares when positions expire in the money.
Many experienced options traders appreciate this feature because it removes overnight assignment concerns that sometimes occur with ETF options.
Volatility Since 2022
Since 2022, implied volatility has repeatedly expanded during periods of market uncertainty.
Examples include:
- Federal Reserve interest rate announcements
- Inflation reports
- Banking sector volatility
- Geopolitical events
- Major earnings seasons
Premium sellers who maintained disciplined risk management often benefited from periods when implied volatility contracted after these events.
However, elevated volatility also increases the probability of larger market moves, making position sizing especially important.
Risk Management Matters More Than Product Selection
Many traders spend considerable time debating whether SPY or SPX is the better vehicle.
In reality, long-term profitability is often determined more by execution than by product selection.
Important considerations include:
- Position sizing
- Strike selection
- Days to expiration
- Implied volatility at entry
- Profit-taking rules
- Maximum loss limits
Two traders using identical products can experience dramatically different outcomes depending on how consistently they apply their trading plan.
Backtesting Credit Spread Strategies
Historical backtesting has become an increasingly valuable tool for evaluating options strategies.
Rather than relying on assumptions or isolated examples, traders can analyze thousands of historical trades across different market environments.
Backtesting allows traders to answer questions such as:
- Which delta produced the highest historical win rate?
- How did 30-day credit spreads compare to 45-day spreads?
- Was closing at 50% of maximum profit historically more effective than holding until expiration?
- How did different market volatility regimes affect results?
- Which combinations of strike width and expiration generated the best risk-adjusted returns?
Using historical data enables traders to evaluate strategies objectively before risking capital in live markets.
Taxes and Other Considerations
Another difference many traders evaluate is tax treatment.
Depending on an individual's jurisdiction and circumstances, index options and ETF options may receive different tax treatment. Because tax rules vary and can change over time, traders should consult a qualified tax professional to understand how those rules apply to their own situation.
Transaction costs, commissions, and account size should also be considered when deciding which product best fits a particular trading approach.
Which Is Better?
For many retail traders, SPY remains an excellent choice because of its accessibility, flexibility, and highly liquid options market.
SPX may appeal to traders who prefer cash settlement, want to avoid early assignment risk, or trade larger position sizes with fewer contracts.
Neither product is inherently more profitable simply because it is SPY or SPX. Profitability depends on the quality of the trading strategy, disciplined risk management, market conditions, and consistent execution over time.
Final Thoughts
Since 2022, both SPY and SPX have provided numerous opportunities for credit spread traders across a wide range of market conditions. Elevated implied volatility, frequent market swings, and abundant liquidity have created an environment where defined-risk premium-selling strategies remain attractive for many participants.
Rather than focusing solely on which product is superior, traders often benefit more from understanding how different strategy parameters have performed historically. Backtesting can help identify strengths, weaknesses, and risk characteristics across multiple market environments, providing valuable insights before committing real capital.
Whether you trade SPY or SPX, combining disciplined risk management with historical analysis can help you make more informed decisions and build greater confidence in your options trading strategy.
