Imagine that you are going to get married and wish to buy a house in 1 year time, you do not have the cash you need to buy a house. Assuming that the housing market is in good time and you expect that the house price will be increased soon, what can you do?
If there is a kind of contract that you can buy to reserve the house at certain price for a period of time, isn’t that good? To purchase this contract, you simply pay fraction of the total house price, let say 1% which is $1000 out of the total value of $100K (assuming this is the house price).
Now you have the right to exercise the contract and buy the house at 100K within 1 year time frame. Your contract will be expired and become worthless after that. The story does not end here, if the house price increased from $100K to $110K 3 months later, you have suddenly change your mind for not buying that house anymore, you have the choice to sell this contract away at $1K (the original price) + $10K (the increase value) = $11K with the gain of $10K.
In the end of the story, you simply earn the difference without forking out the $100K lump sum in the first place, this is what we call “leverage”.
Before learning more, you need to familiar with certain terminology:
- Call Option – Call Option is the right to buy the underlying instrument at predetermined price (Strike price) within certain time frame (expiration date) without any obligation.
- Put Option – Put Option is the right to sell the underlying instrument at predetermined price (Strike price) within certain time frame (expiration date) without any obligation.
- Strike Price – the target price of the underlying instrument
- Expiration date – the option will become worthless after the expiration date
- Options Premium – the price that you need to pay to purchase the option. Usually stock options have the multiplier of 100, if a stock option is quoted for $1 a contract; it will cost $100 to purchase that contract.
- Exercise – buyer of the options has the right to exercise it by buying or selling the underlying instrument at the predetermine price (Strike Price) any time before the expiration date (this is applied for American type options). The options will be automatically exercised if the options are In the Money when it has expired.
- Assignment – Seller of the options take on an obligation to honor the options contract. When assignment takes place, if the option was a call option, the seller would have to sell the underlying instrument at the predetermined strike price.
- In the Money (ITM) – In the case of Call options, ITM means the market price of the underlying instrument is more than your strike price. For Put options, it means the market price of the underlying instrument is less than your strike price.
- At the Money (ATM) – The market price of the underlying instrument is the same as your strike price (Call or Put)
- Out of the Money (OTM) – In the case of Call options, OTM means that the market price of the underlying instrument is less than your strike price. For Put options, it means the market price of the underlying instrument is more than your strike price.
Option has the following characteristics:
- Options give you the right to buy or sell an instrument without any obligation.
- If you are buyer of an option, you have the right to exercise the option, but you are not obligated to buy (when option is a call) or sell (when option is a put) the underlying instrument.
- If you are seller of an option, you are obligated to deliver, or to purchase the underlying instrument at the predetermined price if the buyer exercises the right to deliver or to sell.
- Options are only valid for a specified period of time, you lose your right to buy or sell the underlying instrument after the expiration date. Options expire on the Saturday following the third Friday of the expiration month.
- Options are available at different strike prices that reflect the price of the underlying instrument.
Your Roles in Options Trading:
- Buyer of Call Option
- Buyer of Put Option
- Seller of Call Option
- Seller of Put Option
There are basically 4 types of participants in options trading, which are listed below.
Buyer roles are quite simple to be understood, but a seller or writer roles could be quite complicated.
Sellers receive credits for selling options. The credit is the amount of money equal to the option premium that you have sold.
As a seller of options, you faced the risk of being assigned when there is more seller than buyer in the market. The benefit of being a seller is that you received the payment first, to close the position, you simply buy it back. Therefore, instead of buy low sell high, you sell high then buy low to earn a gain.
Conclusion:
Options are one of the derivatives that provide better leverage but it can carry high risks at the same time. To be a savvy trader, you need to study the risk involved and the benefit of using the call and put option. I hope that you have a better idea what is the option now.
