Wheel decisions

Choosing a Covered Call Strike After Assignment

Premium is the obvious number and the wrong one to optimise. The strike relative to what the shares actually cost you is what determines the outcome.

You have been assigned. The shares are sitting there, your capital is fully committed, and the wheel says sell calls. The only real decision is the strike — and it is the decision that most often turns a recoverable position into a realised loss.

Start from your effective basis, not the market

Before looking at a single option chain, work out what the shares actually cost you:

effective basis = assignment strike − total premium per share collected
Assigned at $385, collected $6.40/share → $378.60

This is the line that governs everything. A call struck above it means being called away is a profit. A call struck below it means being called away is a loss, whatever the premium looked like.

The trap, with numbers

Say the stock has fallen to $360. The $370 calls pay $3.00 and the $385s pay $0.70. The $370 is tempting — four times the income.

Called away at $370: shares ($370 − $378.60) × 100 = −$860, call premium +$300 → net −$560.
Called away at $385: shares ($385 − $378.60) × 100 = +$640, call premium +$70 → net +$710.

The higher-premium call is worse by $1,270 in the scenario where the stock recovers — which is the scenario you are supposedly hoping for. Selling below basis means betting against your own position.

So how far above basis?

Above the effective basis is the floor, not the answer. The trade-off from there:

Close to the money (roughly 0.30–0.40 delta) pays the most and is called away most often. Good when you are content to exit and start a new cycle — that is the wheel turning as intended, not a failure.

Further out (roughly 0.15–0.25 delta) pays less but leaves room to recover. Sensible when the stock is below your basis and you want income without capping the rebound.

Well out of the money pays little. Occasionally right just before a catalyst you expect to move the stock hard, but mostly it ties up shares for pennies.

When the stock is far below your basis

The genuinely awkward case. The stock is at $330 against a $378.60 basis, and calls anywhere near your basis pay almost nothing. Three defensible choices:

Sell above basis for a small credit and wait. Slow, but every premium lowers the basis and nothing is locked in.

Hold uncovered. No income, full upside. Reasonable if you expect a sharp recovery.

Accept the exit. Sell a call below basis, or just sell the shares, and redeploy the capital into a cycle with a better return on it. Sometimes the right answer to a bad position is to stop funding it.

What is not defensible is selling below basis while telling yourself you want to keep the stock. That combination guarantees the worst outcome of the three if it rallies.

Expiry

Thirty to forty-five days is the common window, because time decay accelerates into the final weeks while the premium is still meaningful. Weeklies pay more per unit of time but demand constant management and rack up fees; long-dated calls tie the shares up for months at poor annualised rates. Judge it annualised — $70 over 30 days on $37,860 committed is roughly 2.2% a year, and seeing that plainly stops small premiums from looking like income.

If you are called away

That is the wheel completing, not a mistake. You sold a put, were assigned, collected call premium, and sold the shares above your effective basis. Compute the whole cycle — every premium, the share gain or loss, divided by the collateral committed and annualised by the days it ran — and compare that against simply having held the stock. That comparison, over many cycles, is the only honest verdict on whether the strategy is working for you.

Frequently asked questions

What strike should I sell a covered call at?

Above your effective basis first — strike minus premium collected. From there, closer to the money pays more and is called away more often; further out pays less and leaves room to recover.

Can I sell a covered call below my cost basis?

You can, and sometimes it is a deliberate exit. But if the stock rallies you are forced to sell at a loss, and the premium rarely covers the difference. Do it only as a chosen exit, never for the income alone.

What delta should I target?

Many wheelers use roughly 0.30 delta as a balance between premium and being called away. Below your basis, no delta is correct — the basis constraint comes first.

How long should a covered call run?

Thirty to forty-five days is common: decay is accelerating and the premium is still worth collecting. Judge any premium annualised against the capital the shares tie up.

Is being called away a bad outcome?

No — it is the wheel completing. You keep the premium plus the gain from basis to strike, your capital is freed, and a new cycle can start.

Stop losing the thread at the first roll. Wheel Ninja stitches every put, roll, assignment, call and share sale into one cycle and scores the return on the collateral it actually tied up.
