| Two options used in combination as a hedge for an underlying exposure to a market price.
| |
| Collar hedges are more complex structures, compared with a simpler cap option or floor option.
| |
| | |
| An advantage of collars for hedging is that they reduce the net premium paid for the hedge. They do this by adding a short option position to the long position in the simple cap or floor.
| |
| | |
| In other words the hedger <i>sells</i> an option (in addition to <i>buying</i> the simple cap or floor option).
| |
| | |
| | |
| The premium received by the hedger reduces their net premium payable. The net premium payable is often zero. (This arrangement is called a <i>zero cost</i> collar.) | |
| | |
| It is also possible - though less common - to construct a <i>negative cost</i> collar, the net premium being <i>receivable</i> by the hedger.
| |
| | |
| | |
| The case where the hedger <i>pays</i> a net premium for the collar is known as a <i>positive cost</i> collar.
| |
| | |
| The result of dealing in the combination of two options as a hedge is to ‘collar’ the all-in hedged expense or income achieved within a range which is acceptable to the hedger.
| |
| | |
| Collars are also known as <i>cylinders</i>, <i>corridors</i> or <i>range forwards</i>.
