Covered Calls on SPY vs. QQQ: How to Screen for the Best Strike Price

The Short Answer: SPY or QQQ?

Both SPY and QQQ work well for covered calls, but QQQ typically pays higher premiums because it carries more implied volatility. If you want steadier, lower-risk income, SPY is the better fit. If you are comfortable with bigger price swings and want fatter premiums, QQQ gives you more to work with.

The key is not picking one ticker and forgetting about it. The best covered-call writers screen strikes every week using three simple filters: delta, days to expiration, and the premium-to-stock-price ratio. We walk through all three below, with real numbers.

Why ETF Covered Calls Attract Retail Traders

SPY tracks the S&P 500. QQQ tracks the Nasdaq-100. Both trade millions of options contracts every day, which means tight bid-ask spreads and easy fills. The Options Industry Council (OIC) lists liquidity as one of the top factors in reducing slippage costs for retail traders, and both ETFs rank among the most liquid options markets in the world.

Because you are selling calls on an index ETF rather than a single stock, you also avoid the binary risk of an earnings surprise wiping out your position overnight. ETFs do not report quarterly earnings. That removes one of the biggest hazards covered-call writers face on individual names like NVDA or AAPL.

One more edge: SPY and QQQ both offer weekly options expiring every Friday. Weekly expirations let you collect premium more frequently and reset your strike each week based on current market conditions.

SPY vs. QQQ: A Side-by-Side Premium Comparison

Let's use real-world reference prices. As of mid-2025, SPY trades near $530 and QQQ trades near $460. Here is what a one-week, out-of-the-money covered call looks like on each, using strikes roughly 1% above the current price.

SPY example: SPY at $530. You sell the $535 call expiring in 7 days. Bid is approximately $2.10. That is a 0.40% return on the stock value in one week, or roughly 20% annualized if you repeat it every week.

QQQ example: QQQ at $460. You sell the $465 call expiring in 7 days. Bid is approximately $2.60. That is a 0.57% return on the stock value in one week, or roughly 29% annualized.

QQQ pays about 40% more premium than SPY for a comparable out-of-the-money strike. The reason is implied volatility (IV). QQQ's 30-day IV typically runs 3 to 5 percentage points higher than SPY's because the Nasdaq-100 holds more growth-oriented, higher-beta stocks. Higher IV means option sellers collect more — but it also means the ETF can move more against you.

Note: These are illustrative figures based on typical market conditions. Always check live quotes before placing a trade.

The 3-Step Strike Screener

You do not need expensive software to screen strikes. You need three numbers available free on any broker platform or the CBOE website.

**Step 1 — Filter by Delta (0.20 to 0.35)**

Delta tells you the approximate probability that the call finishes in the money and triggers assignment. A delta of 0.25 means roughly a 25% chance of assignment. Most income-focused covered-call writers target the 0.20–0.35 delta range. Below 0.20, the premium is too thin to bother. Above 0.35, you are giving up too much upside if the ETF rallies.

For SPY at $530, a 0.25-delta call typically sits around the $537–$540 strike one week out. For QQQ at $460, a 0.25-delta call typically sits around the $466–$469 strike.

**Step 2 — Check Days to Expiration (7 to 21 days)**

Theta, the daily time-decay benefit to the option seller, accelerates in the final 21 days before expiration. Selling calls with 7 to 21 days to expiration puts you in the sweet spot of that decay curve. Going shorter than 7 days compresses your premium too much. Going longer than 30 days slows your income cycle and ties up your shares longer.

Weekly options on SPY and QQQ expire every Friday, so you can run a fresh 7-day cycle each week or a 14-day cycle every other week.

**Step 3 — Require a Minimum Premium-to-Price Ratio (0.30% or higher)**

Divide the option bid price by the stock price. If SPY is at $530 and the call bid is $1.50, the ratio is 0.28% — below the threshold, skip it. If the bid is $2.10, the ratio is 0.40% — acceptable. This filter keeps you from selling calls for pennies when volatility is crushed. It also forces you to compare apples to apples across different-priced ETFs.

Risks You Need to Know Before You Sell

Covered calls are not a free lunch. Here are the four risks that matter most, stated plainly.

**Capped upside.** If SPY jumps from $530 to $550 in a week and you sold the $535 call, you keep the $2.10 premium but miss $12.90 of the rally. In a strong bull market, covered calls drag on total return. FINRA's investor education materials note that covered calls are best suited for neutral-to-mildly-bullish outlooks, not for investors expecting large gains.

**Assignment.** If SPY closes above your strike at expiration, your shares get called away. You receive the strike price plus the premium you collected, but you no longer own the ETF. If you want to keep your position, you must buy the shares back, potentially at a higher price.

**Volatility crush.** After a spike in implied volatility, IV often drops sharply. If you sold a call during high-IV conditions and the market calms down, the call loses value faster than expected — which is good if you want to close early, but it means future premiums will be thinner.

**Tax treatment.** The IRS treats premiums from covered calls as short-term capital gains in most cases, regardless of how long you have held the underlying ETF. Selling a call can also affect the holding period of your shares under IRS qualified covered call rules. Canadian investors should note that the CRA has its own rules on option premiums and adjusted cost base. Consult a tax professional before trading. Neither the OIC nor this publication provides tax advice.

How to Put the Screener to Work Each Week

Here is a simple Monday-morning routine that takes about 10 minutes.

First, check the VIX. The CBOE Volatility Index measures expected 30-day volatility on the S&P 500. When VIX is above 20, premiums are elevated and your screener will find strikes that pass all three filters easily. When VIX is below 15, premiums are thin and you may need to move your strike closer to the money or skip the week entirely.

Second, pull up the options chain for SPY or QQQ on your broker platform. Sort by expiration date — pick the Friday that is 7 to 14 days out. Scan the delta column for calls in the 0.20–0.35 range. Check the bid price and run the premium-to-price ratio calculation.

Third, compare two or three strikes that pass the delta and ratio filters. Pick the one that balances premium income with a strike price you are comfortable being assigned at. If you would be unhappy selling your SPY shares at $537, move to the $540 strike even if the premium is slightly lower.

Finally, enter a limit order at the bid or one cent above the bid. Do not chase the midpoint on a slow market. With SPY and QQQ, the bid-ask spread is usually only a few cents wide, so you will get filled quickly at or near the bid.

Which ETF Should You Actually Choose?

The answer depends on what you already own. Covered calls work best when you are selling calls on shares you already hold, because that is what makes them covered. If you own SPY in your portfolio, sell SPY calls. If you own QQQ, sell QQQ calls. Buying one ETF just to sell calls on it adds unnecessary complexity.

If you are starting fresh and choosing between the two specifically for a covered-call income strategy, here is the practical breakdown. Choose SPY if you want lower volatility, smaller premium swings week to week, and a portfolio that tracks the broad market. Choose QQQ if you want higher premiums, are comfortable with tech-sector concentration risk, and can handle weeks where the ETF moves 2% or more against your position.

Many traders run both. They hold SPY as a core position and sell conservative 0.20-delta calls on it, then hold a smaller QQQ position and sell slightly more aggressive 0.30-delta calls for extra income. The two positions tend to move together but not identically, which smooths out the income stream over time.

Is it better to sell weekly or monthly covered calls on SPY?

Weekly calls generate more total premium over a month because you collect four separate premiums instead of one, and theta decay is fastest in the last 7 days before expiration. The trade-off is more transaction costs and more time spent managing the position. Most retail traders start with monthly calls and move to weeklies once they are comfortable with the mechanics.

What delta should I use for a covered call on QQQ?

A delta between 0.20 and 0.30 is the most common range for income-focused covered-call writers on QQQ. A 0.25-delta call means roughly a 25% chance of assignment at expiration. Going higher than 0.35 delta increases your premium but significantly raises the chance your shares get called away.

Can I sell covered calls on SPY in a Roth IRA?

Yes. Most major US brokers allow covered call writing in a Roth IRA because the strategy is considered low risk — you already own the underlying shares. The IRS does not tax gains inside a Roth IRA, so the short-term capital gain treatment that normally applies to option premiums is irrelevant in that account. Check your broker's options approval levels, as you typically need at least Level 1 options approval.

What happens to my covered call if SPY drops sharply?

If SPY falls below your strike price, the call expires worthless and you keep the full premium — that is the best outcome for the call seller. However, your shares are now worth less, and the premium you collected only partially offsets the loss on the stock. Covered calls reduce downside risk slightly but do not protect you from a large market decline.

How do I avoid assignment on my covered call?

The simplest way is to buy back the call before expiration if it moves in the money. Most traders set a mental stop: if the call reaches 200% of the premium received, they close it and reassess. You can also roll the call — buy back the current strike and sell a higher strike or later expiration — to avoid assignment while keeping the position open. The OIC has free educational resources on rolling strategies.

Do covered calls on ETFs get taxed differently than on individual stocks in Canada?

The Canada Revenue Agency (CRA) treats premiums received from writing covered calls as either income or capital gains depending on the frequency of trading and your intent. Active traders are more likely to have premiums taxed as business income at full marginal rates, while occasional traders may qualify for capital gains treatment. The CRA's Interpretation Bulletin IT-479R covers securities transactions in detail, and a Canadian tax professional can help you determine which treatment applies to your situation.
