When Should I Sell Covered Calls After Getting Assigned?
You got assigned shares. Maybe you planned for it, maybe it caught you slightly off guard. Either way, you now own 100 shares of a stock and the wheel keeps moving.
This is where covered calls come in. Setting them up correctly is what makes the whole round trip actually work.
When to start
Once you are assigned, you can begin selling covered calls almost immediately. There is no mandatory waiting period. Most traders look for their first covered call within a day or two of assignment, using the same general framework they used on the put: 30 to 45 DTE, around 30 delta.
The same logic applies. The 30 to 45 day window is where theta decay moves fastest. A 30 delta call means about a 70% chance of expiring worthless, which means you keep the full premium and run it back next cycle.
The number you have to get right: your net cost basis
Here is the part that trips people up. Your covered call strike needs to be at or above your net cost basis. Not the current stock price, and not the put strike you were assigned at.
Net cost basis = put strike minus the premium you collected when you sold the put.
Example: You sold an AAPL put at the $185 strike and collected $3.20 in premium. You got assigned at $185, but your actual cost per share is $181.80. Your covered call needs to be at or above $181.80 to avoid locking in a net loss on the full round trip.
Covered call strikes compared: AAPL assigned at $185, cost basis $181.80
AAPL is currently trading at $178, which is below your cost basis. Here is how different strike choices play out, with 35 DTE and the stock at $178:
| Strike | Delta | Premium (per share) | Premium (per contract) | Above Cost Basis ($181.80)? | Net P&L if Called Away |
|---|---|---|---|---|---|
| $178 | 0.52 | $5.20 | $520 | No | +$140 (shares at loss, offset by premium) |
| $180 | 0.38 | $3.80 | $380 | No | +$200 |
| $182 | 0.28 | $2.70 | $270 | Yes | +$290 |
| $185 | 0.18 | $1.80 | $180 | Yes | +$500 |
The $178 and $180 strikes collect the most premium right now, but if AAPL recovers and your shares get called away at those strikes, you are selling below your cost basis. The premium offsets some of the loss but you still need to account for that gap.
The $182 strike is the first one where you are safely above your $181.80 cost basis. The $185 strike gives you the best total outcome if called away, but it collects less premium since it is further OTM from the current $178 price.
What if the stock is well below your cost basis?
This is the tricky scenario and the table above shows you exactly why. When the stock is sitting below your cost basis, you have two real choices. You can prioritize income now by selling a lower strike for more premium, accepting that a quick recovery might result in being called away at a small overall loss. Or you can be patient, sell a higher strike for less premium, and wait for the stock to climb back toward your cost basis before it gets called away.
Neither is wrong. It depends on how bullish you are on the recovery and how much monthly income you need from the position. Most traders start around the 30 delta strike and adjust from there based on where the stock is relative to their cost basis.
One extra thing: dividends
If your stock pays a dividend and the ex-dividend date falls before your call expiration, be aware that dividends can sometimes trigger early assignment on the call. This happens when the dividend is large enough that exercising early to capture it makes financial sense for the call buyer. It is not something to obsess over, but it is worth knowing when you are choosing your expiration dates.
The short version
Sell covered calls at or above your net cost basis (put strike minus the premium you collected), using the same 30 to 45 DTE, 30 delta framework. If the stock is below your cost basis, use the table above as your mental model: weigh income now against outcome if called away. The wheel keeps working as long as you keep turning it.
