Introduction
An option is a contract that gives the buyer a right, but not an obligation, to buy or sell something at a set price before a certain date. The underlying thing could be a stock, index, currency, or another asset.
The buyer pays for this right. The payment is called the premium.
What are the main parts of an option?
Every option has an underlying asset, a set price called the strike price, an expiry date, and a premium. The buyer decides whether to use the right; the seller must follow the contract if the buyer uses it.
A call option is a right to buy. A put option is a right to sell. You do not need to trade options to invest, but knowing these terms helps explain why options appear in some portfolios.
What happens to the premium?
The buyer pays the premium whether or not the option becomes useful. If the market does not move in the expected direction before expiry, the buyer may let the option expire and lose the premium.
The seller receives the premium but takes on an obligation. Depending on the contract, the seller may face very large losses if the market moves sharply in the buyer’s favour.
Why do people use options?
Options can be used to protect an existing investment, generate income, or take a view on a possible price move. These strategies can involve several contracts and are easy to misunderstand.
An option is not the same as owning the underlying stock or asset. The option has its own price, expiry, and conditions, and it can lose value even if the underlying asset only moves a little.
What are the risks?
Options can expire worthless, lose value quickly, or create losses larger than the original amount paid. The contract may also be hard to sell at a fair price. Selling options can create especially serious obligations.
A step to take:
Do not trade an option until you can explain its strike price, expiry date, premium, maximum possible loss, and what happens at expiry.
Final Thoughts
An option is a time-limited right to buy or sell an asset at a set price. The premium buys the right, but it does not guarantee a profit. Options are complex and risky, so beginner investors should learn the full contract before using them.
