Price related Greeks
The most common term that comes to mind when a trader hears option greeks is probably delta. There is another price related greeks which is Gamma. If anything delta is probably thought of first because it is is easiest to understand.
Delta Option
Options delta is the amount of the options price will change based on one unit change in the underlying security. If a stock or unit would represent $1 change in the price of the stock. For index options this would be reflects by one change in the index.
For a call option The delta will always be a number between 0 and 1. If a call option has a delta of .50 then $1 one increases in the value of the underlying stock would result in the .50 increases in the value of of the call option.conversely of $1 drop in the price of the stock would result in a .50 drop in the value of the call option.
For put option The delta will fall somewhere between -1 and 0.the inverse nature of the delta of a put option relative to a call option relates to the price action of a put relative to move in the underlying security.when I stroke rays is the put option losers value and when I stock move slower the put option increase in value. The this relationship results in the negative sign in front of the delta for put.
In the case of a put option has a delta of -.50 with off one gain in the underlying a stop the put option would loose . 50. Dollar 1 drop in the stock would actually result in a .50 gain in the value of an option.put options benefit from A drop in the underlying security and the level of the delta gifts and indication of just how much of a price move to expect out of put option based on a dollar 1 move in the underlying.
The delta may also referred to in some place as a percentage between 0 percent and 100 percent.the math works out the same if the delta of a call option is shown at 50% instead of . 50, this can be taken as the call option will move 50% as much of the move in the underlying security. If the underlying moves up or down dollar one then the option would increase or decrease by 50% of dollar 1.
traders main use delta to determine what sort of impact a move in the underlying will have on their position. This comes in to play more for position with multiple legs. Spirit trade will really move in lock step with a move in the underlying due to the unique outcome that has been created with multiple options.
Another use of delta might be when using Option to hedge your position for portfolio.when protecting an acid such as a long stock position by purchasing ports and investor may check out the delta of determinant how the hedge will walk. Another way to refer to being haste is being delta neutral.if I spread position has positive delta when the underlying moves high then the spread position would increase in value at the rate of the positions delta.spread that has negative delta would increase the value of the underlying loss value.finally if I sprayed has neutral delta than a price move in the underlying would result in no gain or loss to the spread position.
Shyam traders mostly professional actually have a second use for a delta other than estimating the price change of an option based on a change in the underlying.all through the math is less than perfect The delta is considered by some as the change that an option will finish in the money at expiration. For example at the money call option have a delta very close to.50, which can be considered a 50% chance that the option will be in the money at expiration. An at the money put option should have the delta very close to -.50,taking the absolute value of this also result in option having a 50% chance of being in the money at expiration.
Deep in the money call have a delta that comes very close to if not right to 1. When the delta of call option is at or very close to one this could be considered a case of the market giving the option close to 100% chance of being in the money at expiration.for put option when the option is Deep in the money The delta would be very close -1. This would also be a case of market pricing close to 100% chance that the option will finish in the money at expiration.
Call and put options are very far out of the money would both have a delta very close to zero.with a delta near zero the market is indicating the odd very close to zero percentage that the option will finish in the money at expiration.sometimes that is consistent between the delta for both put and call option is that the delta does not remained at a certain level. The delta will shift around as the price of underlying security changes.the amount that a delta moves up or down based on one unit change in the underlying security is the other price related greeks known as Gamma.
