How Options Work?
An Option always has three key details: the strike price, the expiry date, and the premium.
The strike price is the agreed price at which the underlying asset can be bought or sold.
The expiry date is the final date by which the Option can be used.
The premium is the cost paid by the buyer for the right.
If the market moves in favour of the buyer, the Option gains value and can either be sold to another trader or exercised to gain a profit. If the market does not move as expected, the buyer can simply let the contract expire, losing only the premium paid.
This flexibility makes Options attractive, as they provide a choice without binding the investor to act if the outcome is not beneficial.
Features of an Option Contract
Here are the main characteristics of an Option contract:
Derivative Nature: The value of an Option depends on the performance of the underlying asset.
Expiry Date: Every Option has a set date when it expires. After this, the contract becomes invalid.
Strike Price: This is the price fixed in advance at which the asset can be bought or sold.
Speculative Tool: Traders use Options to speculate on future price movements with lower upfront costs than buying shares directly.
Hedging Tool: Investors use Options to protect themselves from potential losses in other investments.
No Obligation: The buyer has the right to exercise the Option but is not forced to do so.
Settlement: The Option is settled when the buyer decides to use their right to buy or sell.
Contract Size: Each Option comes with a lot size, meaning a fixed number of shares or units of the asset covered by the contract.
Types of Options
There are two main categories of Options:
Call Option
A call option gives the option holder the right, but not the obligation, to purchase the underlying asset at the strike price prior to the option expiration date. Generally, traders purchase call options when they expect the price of an asset to increase.
Put Option
A put option gives the option holder the right, but not the obligation, to sell the underlying asset at the strike price prior to the expiration date. Generally, traders use put options when they expect the price of an asset to decrease.
Both call and put options give investors flexibility given their view of the market.
How Options Are Priced?
The price of an Option, also known as the premium, is determined by two main components:
Intrinsic Value: This is the real, immediate value of the Option. For a call option, it is the difference between the current market price and the strike price if the market price is higher. For a put option, it is the difference if the market price is lower than the strike price. If there is no difference, the intrinsic value is zero.
Extrinsic Value (Time Value): This is the additional value that comes from the time left until the Option expires, as well as market conditions such as volatility and interest rates. The longer the time to expiry or the greater the market volatility, the higher the premium.
Traders use models such as Black-Scholes to calculate fair prices, but in practice, market demand and supply also affect the premium.
Terminology of Options
To trade Options effectively, it is important to know some common terms:
At-the-Money (ATM): When the strike price is the same as the market price of the asset.
In-the-Money (ITM): When an Option has real value. For calls, the strike price is lower than the market price. For puts, the strike price is higher than the market price.
Out-of-the-Money (OTM): When an Option has no real value. For calls, the strike price is higher than the market price. For puts, it is lower.
Premium: The cost paid to buy the Option.
Strike Price: The fixed price at which the asset can be bought or sold.
Underlying Asset: The stock, index, currency, or commodity linked to the Option.
Implied Volatility (IV): A measure of how much the market expects the asset’s price to move in the future.
Exercise: Using the right to buy or sell the asset through the Option.
Expiration: The date when the Option contract ends.
Knowing these terms helps investors understand how Options work in the market.
Advantages and Disadvantages of Options
Like all financial tools, Options have their benefits and drawbacks.
Advantages
Lower Investment Cost: Investors can take positions in the market without needing large amounts of money.
Flexibility: The buyer can choose whether or not to exercise the Option.
Risk Management: Options can be used to protect existing investments from unfavourable price movements.
Profit Potential: Investors can benefit from both rising and falling markets, depending on the type of Option used.
Disadvantages
Complexity: Options are not as simple as buying shares, and beginners may find them difficult to understand.
Limited Life: Options expire after a certain date, which means they can lose all value quickly.
Loss of Premium: If the market does not move in the expected direction, the premium paid is lost.
Market Risk: Options are affected by market volatility, which makes them riskier than some other investment types.

Conclusion
Options are valuable financial instruments that allow investors to manage risk and take advantage of price movements without directly owning the asset. The basic Options meaning is that they give the right, but not the obligation, to buy or sell an asset at a fixed price before a set date.
They provide flexibility, can reduce losses, and open up profit opportunities. At the same time, they are complex, carry risks, and require careful understanding before use.
Used carefully, Options can be a powerful addition to an investment portfolio, but they should always be approached with knowledge and caution.
