What is call
and put option?
- Call option gives the buyer of the option the right to
buy.
- Put option gives the buyer of the option the right to
sell.
- Call option gives the writer of the option the obligation to
sell.
- Put option gives the writer of the option the obligation to
buy
When the
options will be exercised or lapsed?
- A call option is exercised (in the money) when it is profitable
to the buyer of the call option. That is when, exercise
price<market price. In such situations buyer can buy that
particular underlying asset at a cost which is lower than the
market price.
- A put option is exercised (in the money) when it is profitable
to the buyer of the put option. That is when, exercise
price>market price. In such situations buyer can sell that
particular underlying asset at a price which is higher than the
market price.
profit in the
prospective of buyer and writter
- When the option is exercised, buyer will make profit, on the
other hand writer incurs loss.
- so the buyer wants the option to be in the money, whereas
writer wants it to be out the money or lapse.
A writer of a call option will want the value of the
underlying asset to decrease, and a buyer of a put option will want
the value of the underlying asset to decrease
