What are option contract / Call and Put Options Definitions and Examples.
Option contract. |
Option is a contract that gives the right, but not an obligation, to buy or sell the underlying asset on or before a stated date/day, at a stated price, for a price. The party taking a long position i.e. buying the option is called buyer/ holder of the option and the party taking a short position i.e. selling the option is called the seller/ writer of the option. The option buyer has the right but no obligation with regards to buying or selling the underlying asset, while the option writer has the obligation in the contract. Therefore, option buyer/ holder will exercise his option only when the situation is favourable to him, but, when he decides to exercise, option writer would be legally bound to honour the contract.
Option, which gives buyer a right to buy the underlying asset, is called Call option and the option which gives buyer a right to sell the underlying asset, is called Put option.

Call Option And Put Option |
Types of option :
1) Index option:
These options have index as the underlying asset. For example options on Nifty, Sensex, etc.2) Stock option:
These options have individual stocks as the underlying asset. For example, option on ONGC, NTPC etc.3) Buyer of an option:
The buyer of an option is one who has a right but not the obligation in the contract. For owning this right, he pays a price to the seller of this right called option premium’ to the option seller.4) Writer of an option:
The writer of an option is one who receives the option premium and is thereby obliged to sell/buy the asset if the buyer of option exercises his right. American option: The owner of such option can exercise his right at any time on or before the expiry date/day of the contract.5) European option:
The owner of such option can exercise his right only on the expiry date/day of the contract. In India, Index options are European.What is Expiration Day in Option contract.
The day on which a derivative contract ceases to exist. It is the last trading date/day of the contract. Like in case of futures, option contracts also expire on the last Thursday of the expiry month . In our example, since the last Thursday (i.e., May 29, 2018) is a trading holiday, both the call and put options expire one day before that i.e. on 28 May, 2018. Weekly Options are the Exchange Traded Options based on a Stock or an Index with shorter maturity of one or more weeks. If the expiry day of the Weekly Options falls on a trading Holiday, then the expiry will be on the previous trading day.
What are Spot price and Strike price
Strike vs Sopt. |
1) Spot price:
It is the price at which the underlying asset trades in the spot market. In our examples, it is the value of underlying viz. 10154.20. 2) Strike price or Exercise price :
Strike price is the price per share for which the underlying security may be purchased or sold by the option holder. In our examples, strike price for both call and put options is 10000.What are ITM, ATM OTM contract :
ITM,ATM,OTM |
This option would give holder a positive cash flow, if it were exercised immediately. A call option is said to be ITM, when spot price is higher than strike price. And, a put option is said to be ITM when spot price is lower than strike price. In our examples, call option is in the money.
2) At the money (ATM) option:
At the money option would lead to zero cash flow if it were exercised immediately. Therefore, for both call and put ATM options, strike price is equal to spot price.3) Out of the money (OTM) option:
Out of the money option is one with strike price worse than the spot price for the holder of option. In other words, this option would give the holder a negative cash flow if it were exercised immediately. A call option is said to be OTM, when spot price is lower than strike price. And a put option is said to be OTM when spot price is higher than strike price. In our examples, put option is out of the money.Uses of Options contract :
Traders an important decision that a trader needs to make is which option he should trade: inthe‐money, at‐the‐money or out‐of‐the‐money. Among other things, a trader must also consider the premium of these three options in order to make an educated decision. As discussed earlier there are two components in the option premium – intrinsic value and time value. If the option is deeply in‐the‐money, the intrinsic value will be higher and so is the option value/premium.In case of at‐the‐money or out‐of‐the‐money options there is no intrinsic value but only time value. Hence, these options remain cheaper compared to in‐the‐money options. Therefore, option buyer pays higher premium for in‐the‐money option compared to at‐the‐money or out‐of‐the‐money options and thus, the cost factor largely influences the decision of an option buyer.
For ATM options, the uncertainty is highest as compared to ITM or OTM options. This is because we know that when an option is ITM or OTM, even if the price moves somewhat, in any direction, still the option will largely remain ITM or OTM as the case may be.
But in case of ATM options, even a small price movement in either direction can tip the option from ATM to ITM or OTM. There is a huge uncertainty here and this uncertainty is a function of time to expiry and volatility of the underlying, both of which are captured in the time value

The analogy I have used might not be 100% correct but it’s easy to understand things with a simpler analogy.
