Introduction to Options
What Is an Option?
An option is a financial contract that gives the buyer a choice—an option—but not a requirement, to buy or sell an underlying asset at a set price on or before a specific date. Think of it like putting a deposit on a house. You pay a small fee to lock in the purchase price for a certain period. You have the right to buy the house at that price, but you're not forced to. If you change your mind, you just lose the deposit.
In the world of trading, that deposit is called a premium. The locked-in price is the strike price, and the underlying asset is usually a specific number of shares of a stock, like 100 shares of Apple. The contract also has an expiration date, after which it becomes worthless.
Options are contracts that give buyers the right (not obligation) to buy or sell assets at predetermined prices before expiration dates, with standard contracts typically covering 100 shares.
Buyers and Sellers
Every options trade has two sides: a buyer and a seller. Their roles and motivations are opposites.
The buyer, also called the holder, pays the premium to acquire the rights granted by the contract. Their risk is limited to the premium they paid. If the trade doesn't go their way, the most they can lose is the cost of the option itself. The potential for profit, however, can be substantial.
The seller, also known as the writer, receives the premium from the buyer. In exchange, they take on an obligation. If the buyer decides to use their right to buy or sell the asset, the seller must fulfill their end of the deal. The seller's profit is capped at the premium they received, but their potential loss can be much larger.
| Role | Action | Right or Obligation | Max Profit | Max Loss |
|---|---|---|---|---|
| Buyer | Pays Premium | Gains the right to buy or sell | Potentially unlimited | Premium paid |
| Seller | Receives Premium | Takes on the obligation to buy or sell | Premium received | Potentially unlimited |
The Two Types of Options
Options come in two basic flavors: calls and puts. They're mirror images of each other, designed for opposite market predictions.
Call Option
noun
A contract giving the owner the right, but not the obligation, to buy an underlying asset at a specified price within a specific time period.
You buy a call option when you expect the price of an asset to go up. A call gives you the right to buy the stock at the strike price, no matter how high the market price climbs. If you're right and the stock price soars past the strike price, you can buy it at a discount and sell it for a profit.
Put Option
noun
A contract giving the owner the right, but not the obligation, to sell an underlying asset at a specified price within a specific time period.
Conversely, you buy a put option when you expect the price of an asset to go down. A put gives you the right to sell the stock at the strike price. If the stock's price falls below the strike price, you can still sell it at that higher, locked-in price, making a profit from the decline.
This choice between calls and puts is the foundation of all options trading. It allows traders to act on their predictions of whether a stock will rise or fall, without having to buy the stock itself.
