30 delta or 50 delta: which covered call should you sell?

A 50 delta call sits at the stock's price. It pays the most and is called away about half the time. A 30 delta call sits above the price, pays less, and leaves room for the stock to rise. Here's every outcome.

The short answer

A 50 delta covered call has a strike right at the stock's price (at the money). It pays the biggest premium of the two, gives the most cushion on a small dip, and the market prices it with about an even chance of finishing in the money. You'll be called away often.

A 30 delta covered call has a strike above the price. It pays less, but you keep any rise up to the strike, and the market sees roughly a 3 in 10 chance of it finishing in the money.

Pick 50 delta when you'd be happy to sell the shares now. Pick 30 delta when you'd rather keep them and leave room to grow.

What delta means on a covered call

Delta tells you how much the call's price moves for each $1 the stock moves. A 50 delta call moves about $0.50. A 30 delta call moves about $0.30.

Sellers also use delta as a rough guide to the chance of the call finishing in the money, which for a Covered call means the chance of being called away. It's a market estimate from Implied volatility, not a forecast. See options Greeks explained.

Every outcome, side by side (an illustration, not a trade idea)

You own 100 shares of a made-up stock, XYZ, bought at $50. You compare two 30-day calls:

• 50 delta: the $50 strike for $2.00. You collect $200.
• 30 delta: the $53 strike for $0.90. You collect $90.

Three things to see:

1. Below $50, the 50 delta call is better by $110, the extra premium. It's a small cushion, not protection.
2. Above about $51.10, the 30 delta call is better, by up to $190, because you keep the rise to $53.
3. On a big fall, both lose almost the same. Neither call protects the shares much. Our covered call strategy guide shows why.

The upside you give up

The 50 delta call caps your gain at the price you're at today. Any rise belongs to the call buyer. If XYZ goes from $50 to $60, a plain shareholder is up $1,000. You're up $200.

The 30 delta call gives you room to $53. You keep $300 of any rise, plus the premium. Above that, you're capped too, but later.

That's the core trade:

When each one fits in the wheel

In the wheel strategy, the call stage comes after you've been assigned on a put. Which delta you pick depends on what you want next.

A 50 delta call fits when:

• You'd be glad to sell the shares at today's price and start over with a new put.
• You think the stock will drift sideways, and you'd rather have the bigger premium.
• The strike is at or above your cost per share. If it's below, being called away locks in a loss. See the strike-below-cost trap.

A 30 delta call fits when:

• You like owning the stock and would rather keep it.
• You want some room for a rise, and you accept a smaller premium for it.
• You're holding shares bought at a cost above today's price, and a strike above your cost happens to be near 30 delta.

Watch out for:

• Dividends. An at-the-money or in-the-money call is more likely to be exercised early just before an Ex-dividend date.
• Earnings. A report inside the call can move the stock far past either strike.
• Chasing the premium. A 50 delta call on a jumpy stock pays a lot because the market expects big moves, both ways.

How to choose for your next call

1. Write down your cost per share, with any put premium taken off.
2. Ask: would I be happy to sell at today's price? If yes, look at 50 delta. If not, look further out.
3. On the Options chain, find the strikes near 30 and 50 delta. Note each premium.
4. Fill in a table like the one above with your numbers, including the $40 row.
5. Pick the one where every row is a result you'd accept.
