Weekly vs monthly options for sellers: does faster always pay more?

Weekly options decay faster and seem to add up to more premium over a year. Monthlies give one decision, one spread to cross and more room for the stock to move. Here is the paper math, and what tends to happen in real life.

The short answer

Weekly options expire every Friday. A seller makes a new decision every week, crosses the bid-ask spread every week, and collects a small premium each time. The decay is fastest in the last days, and so is the swing in the option's value.

Monthly options expire on the third Friday. One decision, one spread, one premium that's bigger per contract but smaller per week. More room for the stock to move before the strike matters.

On paper, weeklies add up to more. In practice the gaps, the spreads and the extra decisions take much of it back.

Side by side

The paper math that gets people excited

A made-up stock, XYZ, trades at $50. A weekly $52 call might go for $0.30. A monthly $55 call might go for $1.00.

Four weeklies: 4 × $0.30 = $1.20. One monthly: $1.00. The weekly seller looks ahead by $0.20 over the same four weeks, and that's the whole argument for weeklies.

It assumes four calm weeks in a row, four fills at the quoted price, and no fees. None of those is free.

A worked example (an illustration, not a trade idea)

Two traders each own 100 shares of XYZ bought at $50.

• The weekly seller sells the $52 call for $0.30 each Monday.
• The monthly seller sells one $55 call for $1.00.

Weeks one and two are quiet. The weekly seller collects $30, then $30 again. Then XYZ gaps down over a weekend to $40.

The weekly seller's edge from the paper math is gone. Two tiny cushions were worth less than one bigger one.

Now the harder part. The weekly seller wants to "earn it back" and sells a $41 call for $0.40, because that's what the chain offers near the price. The monthly seller still has the $55 call open and does nothing.

XYZ bounces to $46 that week and stays there.

The weekly seller locked a loss in. The $41 call looked like a small, sensible premium on the day. It was a promise to sell shares below cost, made in a hurry because the calendar said it was time to sell something.

Where the weekly premium leaks

• The spread. If the bid-ask spread is $0.05 on a $0.30 option, the spread is a sixth of the premium, and you pay part of it on every fill. On a $1.00 monthly with the same spread, it's a twentieth.
• Gamma. In the last days before expiry, an option near the strike swings hard on small stock moves. Weeklies live in that zone every week. See theta vs delta.
• Commissions. Four times the trades, four times the fees.
• Attention. Weekly sellers are at the screen every Monday and Friday. That's when "I should sell something" turns into selling below cost.

When weeklies make sense

• You're selling a call on shares you'd happily lose and want the strike re-set often.
• The stock is calm and liquid, with tight spreads even on the short-dated chain.
• You have a written rule for the week after a drop, so you don't repeat the $41 call.

Most people running the wheel strategy use monthlies or expiries 30 to 45 days out. It isn't a law; it's a way to make fewer decisions. Theta decay explained shows why the last week behaves differently.

What to do with this

1. Write down what you'll do the week after a gap, before it happens. "No call below my cost" is a fine first rule.
2. Check the spread on the exact contract. If it's more than a tenth of the premium, the weekly isn't cheap.
3. Try one monthly cycle and four weekly cycles on paper, side by side, and count the decisions, not just the premium.
