Option Delta

Delta is probably the first Greek an option trader learns and is focused on. The ratio comparing the change in the price of the underlying asset to the corresponding change in the price of a derivative
In fact it can be a critical starting point when learning to trade options. A positive delta means the position will rise in value if the stock rises and drop in value of the stock declines. A negative delta means the opposite. The value of the position will rise if the stock declines and drop in value if the stock rises in price. Delta is one of four major risk measures used by option traders. Delta measures the degree to which an option is exposed to shifts in the price of the underlying asset. Delta tends to increase as you get closer to expiration for near or at-the-money options. Delta is not a constant

Call Options

Whenever you are long a call option, your delta will always be a positive number between 0 and When the underlying stock or futures contract increases in price, the value of your call option will also increase by the call options delta value.

Put Options

Put options have negative deltas, which will range between -1 and 0. When the underlying market price increases the value of your put option will decreases by the amount of the delta value. Conversely, when the price of the underlying asset decreases, the value of the put option will increase by the amount of the delta value.

 

 

Is the Long Call Option the Same as the Short Put option?

Long calls are not the same as short puts. Buyers of option contracts are long, while sellers or writers of option contracts are short. Call and put options give you the right to buy or sell the underlying securities at specified prices, known as strike prices, before predetermined expiration dates. Long and short option strategies have different risk-return profiles, with downside risk usually limited for long positions.

Basics

The relationship between strike prices and market prices determines profits and losses. A long call is profitable when its strike price is below the market price of the underlying stock, while a long put is profitable when its strike price is above the market price. The reverse is usually true for short calls and puts. You pay a premium, which is the market price, when you open or buy an option contract, and you receive the premium when you sell or close an option contract.
