Chapter 01 · Combining option positions
Why one contract is not always enough
A single option takes one view and leaves every other risk open. A combination is two or more contracts used so that one risk is reduced and another is accepted on purpose. This chapter is about that trade-off, before any named strategy.
Every option is already a bundle
A long call gains if the underlying rises far enough to cover the premium, loses the premium if it does not, and changes value before expiry when time passes or when the market’s expectation of movement changes. You did not buy ‘up’. You bought up, plus a race against the clock, plus a view on whether movement was cheap or expensive. If you only wanted up, and you wanted it slowly, the call may be the wrong instrument even when you are right about the direction.
Adding a second contract is how you cancel one of those pieces. Sell a higher-strike call against the one you bought, and you give away the gains above that higher strike in exchange for a smaller net premium. You are no longer paid for a very large move. You have decided a very large move is not the outcome you are willing to pay for. That is a reasonable decision when you can say it out loud. It is an accidental decision when the second leg was added because someone called it an adjustment.
Defined loss is a property of the whole position
A long option has a defined loss: the premium. A short option does not. A spread that is long one strike and short another can have a defined loss if the quantities match and both legs are kept until expiry or closed together. The moment the quantities do not match, or one leg is closed and the other is left open, the definition is gone. The broker’s strategy name does not enforce this. Your orders do.
Margin follows the risky leg. A short option will block margin even when a long option sits beside it, though a recognised spread may receive a lower margin than a naked short. Lower is not zero. Check the blocked amount on the day, because span and exposure margins move with volatility and with the exchange’s current method.
A view, translated into what you are willing to give up
| What you actually believe | A single contract does | A combination is for |
|---|---|---|
| It will move a long way, soon, and I will be wrong quickly if not. | A long option matches the ‘wrong quickly’ part. | You may not need a second contract. |
| It will rise, but not past a level I can name. | A long call still pays for the rise past that level, which you do not believe in. | Paying less by selling the higher strike. |
| I already own the shares and will sell them if they reach a price. | A short call without the shares is a different, larger risk. | Selling the call only against shares you already hold. |
| I own the shares and I want a floor for a few weeks. | Hoping is not a floor. | Buying a put, and accepting that the premium is the cost of the floor. |
Costs and the habit of adjusting
Each leg has a spread, charges, and a chance of a bad fill. A four-leg position pays that stack four times to get in and, if you are orderly, four times to get out. Adjusting — closing one leg because it feels uncomfortable and replacing it — can turn a defined loss into an undefined one for the hour in which only one leg is live. If you adjust, write the new position down as a fresh decision with a fresh maximum loss. Do not call it the old position with a patch.
What to remember
- A single option bundles direction, time, and the price of movement. You may not want the whole bundle.
- A second contract removes a risk only if the quantities match and the legs stay on together.
- The maximum loss belongs to the position you have now, not to the position you had this morning.
- Strategy names do not enforce the hedge. Orders do.
- Every leg costs money to enter and to leave. Count the stack before you call a combination clever.
