Renting out shares you already own — and the one strike rule that stops it going wrong.
2 min read
A covered call is the second half of the wheel. You own at least 100 shares, and you sell someone the right to buy them from you at a set price. You're paid a premium for that, and in exchange you give up any gain above the strike.
"Covered" means you actually hold the shares. That's what makes it a conservative trade — the obligation is satisfied by stock you already have, not by buying at whatever the market demands later.
Selling a call against assigned shares
You were assigned 100 shares at $50, having collected $1.20 on the put. Net basis: $48.80.
Stock now trades at $49. You sell a 30-day $52 call for $0.90.
Premium received: $90. Net basis drops to $47.90.
Below $52 at expiration: call expires worthless, you keep the shares and the $90, sell another.
Above $52: shares are called away at $52. Total profit = ($52 − $47.90) × 100 = $410.
Never sell a call below your cost basis
If your net basis is $48.80 and you sell a $47 call because the premium looks good, you have locked in a loss. Getting called away at $47 means selling for less than you paid, and the premium rarely covers the gap. This is the single most common way a profitable wheel position turns into a losing one — and it usually happens after a drop, when the higher strikes have stopped paying well and the temptation is strongest.
Wheel Folio tracks your net basis for exactly this reason: it carries every premium you've collected on the cycle into the number, so the floor you shouldn't sell below is always on screen rather than in your head.
| Strike choice | Effect |
|---|---|
| Just above cost basis | Highest premium, most likely to be called away, smallest capital gain |
| Comfortably above basis | Balanced — the usual wheel choice |
| Well above the price | Little premium, but you keep the shares and most of any rally |
A useful question before selling: at what price would I be genuinely pleased to sell these shares? Sell that strike. It converts "my upside got capped" from a disappointment into the plan working.
A covered call is not downside protection. Collecting $0.90 on a $49 stock cushions a 1.8% fall and nothing more. If you're holding shares you're worried about, a covered call is the wrong tool — look at a collar, which pays for a protective put with the call premium.
If the shares get called away, the cycle completes and you're back to cash and selling puts. If the stock has run well past your strike and you'd rather keep it, rolling is the escape hatch.

Educational only
Nothing here is investment, financial, or tax advice. Options carry risk, including losing more than the premium collected, and the examples use round numbers to show the mechanics rather than to suggest a trade. Read risk and position sizing before putting real money behind any of it.
Assignment
The part that makes people nervous, and why on the wheel it's usually just the plan working.
Rolling
Buying back and re-selling to buy time — and the honest test for whether it's helping.
