Sell aggressive calls (closer to the money) when you're okay getting assigned and moving on, and sell defensive calls (further out of the money) when you want to hold the stock longer and collect smaller but safer premium. That single decision — how much do I want to keep this position? — should drive your strike selection every single time.
It Starts With Your Assignment Appetite
Before you even look at the options chain, ask yourself one question: if this stock gets called away at expiration, am I fine with that? Your honest answer determines everything about where you sell.
If you're running the wheel on NVDA and you got assigned at $850 after selling puts, you might have a cost basis around $840 after collecting some put premium. If NVDA is now trading at $870, selling the $880 call for $12 is aggressive — it caps your upside at $880 but you collect solid premium. If it gets called away, you've made roughly $52/share between the premium and the stock appreciation. That's a clean exit. Move on, sell puts again, restart the wheel.
But what if you bought 100 shares of AAPL at $195 and it's your long-term core holding? Selling the $200 call for $2.50 is a completely different situation. Getting called away means losing a position you actually want. That changes the math entirely.
What Aggressive Actually Means
Aggressive covered calls are typically 0.30–0.40 delta, sometimes even 0.45. You're selling strikes that are close to the current price, sometimes only 2–4% out of the money. The premium is real — we're talking 1.5–3% of the stock price in a 30-day expiration — but you have a legitimate chance of losing the shares.
On a $500 stock like NVDA, a 0.35 delta call might sit at the $515 strike with 30 DTE, paying around $14–16. That's not nothing. But if NVDA runs to $530 before expiration, you're capped and you miss $15 of upside. The tradeoff is explicit.
I sell aggressive calls in two specific situations. First, when I'm actively running the wheel and assignment is the goal — I want to collect the premium, get called away, and sell puts again at a lower strike. Second, when a stock has run up fast and I think it's due for a pause or pullback. Selling a closer strike captures elevated IV while also giving me a built-in exit if I'm wrong about the pullback.
What Defensive Actually Means
Defensive calls are 0.15–0.20 delta, usually 7–10% out of the money. The premium is thinner — maybe 0.5–1% of the stock price — but your odds of keeping the shares are much higher. You're essentially renting out the upside you probably weren't going to see anyway.
Take AAPL at $220. A defensive covered call might be the $240 strike at 30 DTE, paying around $2.00–2.50. That's roughly 1% premium. Not exciting, but AAPL would need to move 9% in a month for you to lose the shares. That's a low-probability event most months.
Defensive calls make sense when you're in a position you built intentionally and don't want to lose. They also make sense when IV is elevated — like during earnings season on a stock you're not trading through earnings — because you can sell further out and still collect decent premium just from the elevated volatility.
The Scenario That Trips People Up
Here's where intermediate traders often make a mistake: they sell aggressive calls on stocks they actually like, then get frustrated when shares get called away on a big move. NVDA runs from $870 to $920, you had the $885 call, and now you're mad you missed $35 of upside. But you chose that strike. That was the deal you made.
The fix isn't to always go defensive. It's to be honest with yourself before you sell. If you're upset about the idea of losing the shares, go defensive or don't sell a call at all. If you genuinely don't care about getting called away, go aggressive and collect the better premium.
One practical framework: if your cost basis is more than 5% below the current price and you're comfortable with the profit, sell aggressive. If you're still underwater or you want to hold long-term, go defensive and treat the call premium as a small income stream rather than a core return driver.
Managing After You Sell
Selling the call isn't the last decision. If you sold aggressive and the stock rips 8% in two weeks, you have a choice — buy back the call and roll up, or let it ride to assignment. Rolling costs money but preserves the position. Letting it ride is fine if you planned for assignment anyway.
If you sold defensive and the stock drops 10%, your call is basically worthless. Great — you can let it expire and sell another one, or buy it back for $0.20 and redeploy the capital into a better strike.
The practical takeaway you can act on right now: pull up whatever covered call position you're currently holding or considering, and before you pick a strike, write down whether you want to keep the shares or not. One sentence. That answer should make the strike selection almost automatic.
