Selling Covered Calls Below Your Cost Basis

Selling covered calls below your cost basis is a valid strategy…but only if you understand that being called away means a realized loss.

Suppose you’re sitting on 100 shares you got assigned on, the stock is well below your cost basis, and the above-basis strikes are paying you next to nothing.

Meanwhile, those below-cost-basis strikes are whispering:

• Fatter premiums
• Faster recovery
• Progress

Selling a CC below your cost basis can accelerate cost basis recovery when your thesis is intact and above-basis premiums are pathetic.

However, it is not the default play for most Wheel traders (and I only recommend doing it under certain situations).

If you need a refresher on covered calls, start with What are Covered Calls?.

And give this article on selling above cost basis a read if you want to understand the “default mode” for most Wheel traders.

What “Below Cost Basis” Actually Means (and What You’re Agreeing To)

Here is the primary difference between selling CCs above vs. below cost basis:

• When you sell a covered call above your cost basis, being called away is a profit. You’re selling shares for more than you effectively paid.
• When you sell below your cost basis, being called away is a realized loss, partially offset by the premium collected.

Note: Quick reminder, your cost basis is what you effectively paid per share: the purchase price (or CSP strike you were assigned at) minus all premiums collected. For the full formula, see How to Sell Covered Calls After Assignment.

Here’s what you’re agreeing to when you sell below cost basis:

• If called away, you will realize a loss (you’re selling shares for less than you paid)
• The premium only partially offsets that loss but does not eliminate it
• You’re capping your upside recovery (if the stock rebounds past your strike, you miss it)
• You’re trading time-in-market for faster cost basis reduction

A Common Misconception Regarding Below Cost Basis

There’s a common misconception regarding selling below cost basis that I think is worth addressing:

The premium makes up for it.

It doesn’t. It offsets. Those are different things.

Since below-cost-basis strikes carry higher delta, the premiums are fatter. They reduce your cost basis faster than above-basis strikes would, potentially positioning you better for future cycles.

It’s an accelerator for cost basis recovery…not a magic fix.

Why the Premiums Are Fatter (and Why That’s the Trap)

So, why are below-cost-basis premiums larger?

1. Below-cost-basis strikes are closer to the current stock price
2. Closer to the money means higher delta
3. Higher delta means higher premium, because the buyer is paying for a greater probability that the option expires in the money

But the premium comes with a trap:

1. Anchoring bias: The premium looks big in dollar terms, but you’re ignoring the capped recovery if called away
2. Comparison trap: Compared to the pathetic above-basis premiums, the below-basis number feels like progress
3. Recovery math illusion: You see premium and think you’re healing the position

Remember, your cost basis is your break-even. If you sell a covered call at exactly your cost basis and get called away, you didn’t lose money. But you didn’t make any, either.

You gave back all your premiums. Your ROC is 0% over however long you held the position.

That’s the real trap. You cap your recovery at zero.

Selling below cost basis caps recovery at a loss.

For example:

Suppose you sold a CSP on CRDO (Credo Technology) at the $140 strike and collected $7.00 in premium. That makes your true cost basis $140.00 - $7.00 = $133.00

Afterwards, CRDO drops hard to around $125 and you get assigned at $140, meaning you’re now $8 below cost basis.

You start looking for CCs to sell, but above-cost-basis strikes ($133.50 and up) are far out of the money. The premiums are pathetic.

So you look below cost basis. The $130 strike for 18 DTE is paying roughly $3.50. That’s real money.

You sell it, but then CRDO recovers to $135 by CC expiration resulting in your shares getting called away at $130.

Here’s the math on how that CC cycle played out:

• Sold CC at $130 strike
• Collected $3.50 CC premium
• Effective sale price: $133.50
• Cost basis: $133.00
• Net: $133.50 - $133.00 = $0.50 profit per share

Looks like a win.

But you missed the recovery to $135.

Could you have waited? Absolutely.

If you’d been patient and sold above cost basis at $135, the profit would have been $2.00 or more per share — four times the gain, with room to go even higher.

The $0.50 “profit” masks the opportunity cost. The fat premium looked good, but it locked you out of the real recovery.

When Selling Below Cost Basis Actually Makes Sense

In my opinion, there is only one valid reason to sell below cost basis:

Your thesis is intact, you’re deeply underwater, and you want to accelerate recovery.

• The stock is temporarily down, but you believe in the long-term fundamentals
• You’re willing to accept the risk of being called away because you believe the stock will stay below your strike (meaning the call expires worthless and you keep the premium)
• The accelerated cost basis reduction positions you better for future cycles

That’s the typical case for selling a CC below your cost basis.

However, here’s the counterpoint:

If your thesis is broken, just sell the damn stock. Don’t use below-cost-basis covered calls as an exit strategy. That’s collecting pennies while hoping for a miracle.

Finally, “I just want more premium” is not a valid reason on its own.

Greed for premium without thesis conviction is gambling. The decision comes down to conviction — if you genuinely believe in the stock’s recovery and you’re willing to accept the risk, below-cost-basis CCs can be a deliberate, disciplined tool.

If you’re just chasing fatter numbers on the chain because the above-basis premiums are depressing, step away from the screen.

How to Manage the Risk When Selling Below Cost Basis

Recall that your cost basis is your break-even. You can give back all your accumulated premiums if you sell at cost basis and get called away.

Selling below cost basis means you could give back even more than that.

The question you should ask before every below-basis CC:

How much of my accumulated premium am I willing to give back?

Three levers control your risk.

Strike Selection

Here’s the trade-off on strike selection:

• The closer your strike is to your cost basis, the less you give back if called away…but the less premium you collect
• The further your strike from your cost basis (and closer to the current price), the fatter the premium…but the larger the realized loss if called away

Think in terms of how much of your accumulated premium you’re willing to sacrifice. That’s your strike.

Delta

I recommend keeping it low, typically 0.10-0.20.

Higher delta means fatter premium but dramatically higher probability of being called away. And being called away below cost basis is a realized loss.

The temptation to push delta higher for more premium is strongest when you’re underwater. Resist it.

DTE

For DTE, I suggest a moderate 14-30 DTE when selling CCs below-cost-basis.

Very long DTE on a below-cost-basis strike extends your exposure. The stock has more time to move against you and potentially get called away.

Keep it short enough to react, long enough to collect meaningful theta decay.

Rolling as a Defense

When the stock approaches your strike, you have a defense mechanism: roll out (same strike, later expiration) or roll out and up (higher strike, later expiration).

Rolling buys time and potentially moves the strike closer to your cost basis.

This is your primary adjustment tool when a below-cost-basis CC starts going against you.

(But you should only roll when you can do so for a net credit. Do not roll if it will cost you more money, that’s just digging a deeper hole.)

Worked Example: Below-Cost-Basis Covered Call

Let’s walk through a hypothetical using CDE (Coeur Mining) to see how below-cost-basis strike selection plays out across three different scenarios.

The starting point:

• CSP strike: $22.50
• Premium collected on the CSP: $1.32
• True cost basis: $21.18
• CDE has dropped to $17.50 (deeply underwater, $3.68 below cost basis)

Above-cost-basis strikes ($21.50 and up) are extremely far out of the money from $17.50. The premiums are essentially zero.

Any strike between $17.50 and $21.18 is below cost basis and above the current stock price. That’s realistic, out-of-the-money CC territory — and exactly where below-cost-basis selling becomes a real consideration.

Most importantly, your thesis is intact. You believe CDE recovers. A below-cost-basis CC is justified.

Note: The premiums below are approximate and hypothetical. They are not live market data.

Scenario 1: Strike Well Below Cost Basis, Called Away at a Loss

Suppose we sell a CC with a strike well below our cost basis:

• Strike: $18.50 (moderate delta from $17.50, below cost basis of $21.18)
• Premium: ~$0.60
• CDE rallies to $20
• Shares called away at $18.50

The outcome:

• Effective sale price: $18.50 + $0.60 premium
• Cost basis: $21.18
• Net loss per share: $19.10 - $21.18 = -$2.08

Locked in a $2.08 loss and missed the recovery to $20.

The “fat” premium of $0.60 barely dented the $3.68 gap.

Scenario 2: Strike Near Cost Basis, Called Away at Roughly Zero

Now let’s look at what happens when we sell a CC with a strike near our cost basis:

• Strike: $21.00 (far OTM from $17.50, very low delta)
• Premium: ~$0.15
• CDE rallies hard to $22
• Shares called away at $21.00

In this situation:

• Effective sale price: $21.00 + $0.15 premium
• Cost basis: $21.18
• Net loss per share: $21.15 - $21.18 = -$0.03 (essentially zero)

Months of work. Multiple cycles. All that premium collected…and you gave nearly everything back.

The stock ended up recovering beautifully. You just weren’t positioned to benefit from it.

Scenario 3: Strike Moderately Below Cost Basis, Expires Worthless

Here’s an example of selling a CC that is moderately below cost basis:

• Strike: $19.50 (moderate-low delta from $17.50)
• Premium: ~$0.35
• CDE stays flat around $17-$18
• CC expires worthless

This situation results in:

• Premium kept: $0.35
• New cost basis: $21.18 - $0.35 = $20.83
• Ready for next cycle with a lower cost basis

This is the intended outcome.

• Collect premium. Reduce basis. Repeat.

No drama. Shares stay put. Just a quiet step closer to recovery.

(Not exactly a victory parade, but we’ll take it)

Below Cost Basis vs. Above Cost Basis (When to Use Each)

My suggestion is to default to selling CC above cost basis. Only go below when your thesis is intact and you’re deeply underwater and above-basis premiums are pathetic.

The Scalpel, Not the Hammer

Selling CCs below cost basis is a scalpel, not a hammer.

It’s a deliberate tool for a specific situation:

• Thesis intact
• Deeply underwater
• Above-basis premiums too thin to move the needle

If you’re disciplined about delta, DTE, and strike selection, below-cost-basis CCs can accelerate your recovery. If you’re not, you’re just collecting premium while hoping.

Default to selling CCs above cost basis. Go below only when the conditions demand it.
