Key Concepts
-
Options trading allows traders and investors to buy or sell assets—such as cryptocurrencies and stocks—at a predetermined price, but without any obligation to do so.
-
Most options trading activity and profits come from buying and selling options contracts themselves, rather than exercising them to trade the underlying asset.
-
American options can be exercised at any time before they expire, while European options can only be exercised on the expiration date or the designated exercise date.
-
To make informed decisions in options trading, it is essential to understand call options, put options, option pricing, expiration dates, and strike prices.
Introduction
Options trading gives you the right to buy or sell an underlying asset at a fixed price on a specific date. The word “option” is fundamental here, as what sets options trading apart is that you are not obligated to buy or sell the asset—you simply have the right if you choose to do so.
Think of it like reading a “choose your own adventure” book. At some point, you reach a crossroads in the story and need to make a key decision: pick option (A) or option (B). Instead of deciding immediately, you bookmark the page, continue reading to see how the story plays out, and then return later to make your decision.
This is the core idea behind options trading: traders are not required to buy or sell an asset right away. Instead, they can purchase an options contract, which acts as a financial bookmark—granting the right to buy or sell the asset later, anytime before expiration, but without any obligation. To do this, you pay a premium, which is like the cost of using the bookmark.
Just as you can sell your bookmark to another reader, you can also sell your options contract to another trader before it expires. This lets you profit from changes in the contract’s value without ever buying or selling the underlying asset.
Like “choose your own adventure” books with unexpected twists, options trading also carries risks. It’s important to understand how options contracts work before getting started.
Overview of Options Trading
Options trading involves buying and selling options contracts. To understand how this works in practice, let’s explore the essential components:
What Are Options Contracts?
An options contract grants you the right to buy or sell an asset at a fixed price, called the strike price, on or before a specified date, known as the expiration date, but you are never obligated to do so.
Imagine you’re interested in a house but not ready to commit. Instead, you negotiate an option contract with the seller, giving you the right to buy the house at an agreed price within a set timeframe. You pay a small fee—the option premium—to secure this right.
If the house’s market value rises, you can exercise your contract to purchase at the lower agreed price. If the value falls, you can simply walk away and lose only the premium.
While the strike price stays fixed, the value of the option contract itself fluctuates based on factors like the house’s market price, time to expiration, and market demand. If the house price climbs, your option’s value rises, potentially allowing you to sell the contract for profit without ever purchasing the house.
What Are Call Options?
A call option gives you the right to buy an underlying asset at the strike price on or before the expiration date.
The higher the asset’s market value, the greater your profit potential. You might buy a call option if you believe an asset’s price will increase. If it does, you can buy at the strike price and sell at the higher market price for a profit.
If the call option’s value increases before expiration, you can also sell it to realize a profit—without ever exercising the contract. In this case, you’re trading the contract itself, not the asset.
What Are Put Options?
A put option gives you the right to sell an underlying asset at the strike price on or before the expiration date.
You can buy a put option if you believe the market price of an asset will decline. If the price falls below the strike price, you can sell the asset at the higher strike price. The further the price drops, the more profit you can make—plus, you could buy back the asset at a lower market price.
Like call options, you can sell put options before expiration if their value rises. This lets you profit without exercising the option—a common way calls and puts are traded.
Underlying Asset
We’ve discussed underlying assets and how options contracts provide the right—not the obligation—to buy or sell them. In the earlier analogy, the underlying asset was a house. In financial markets, typical underlying assets include:
-
Cryptocurrencies: You can buy options contracts on digital assets like Bitcoin (BTC), Ether (ETH), BNB, or Tether (USDT).
-
Stocks: You can buy options contracts on shares of companies like Apple (AAPL), Microsoft (MSFT), or Amazon (AMZN).
-
Indices: You can buy options contracts on stock market indices such as the S&P 500 or Nasdaq 100.
-
Commodities: You can buy options contracts on gold, oil, or other commodities.
Trading Before Expiration
You do not need to wait until expiration to realize a return, since you’re trading the options contracts themselves.
Option contract values change constantly based on market conditions and time to expiration. This means you can buy a contract and later sell it for a profit or a loss. Most options trading happens this way—you’re trading the right to buy or sell the asset, rather than the asset itself.
Options Contracts
Now that we’ve covered options trading, let’s break down the components of a real options contract.
Expiration Date
The expiration date is when the options contract becomes void. After this date, the contract is worthless and cannot be exercised. Options can have a range of expiration dates—from weeks to years.
In the house analogy, imagine you purchase an option contract valid for one month. You have a one-month window to decide whether you’ll use your right to buy the house at the strike price.
Strike Price
The strike price is the agreed-upon price at which you can buy (for a call) or sell (for a put) the underlying asset.
Negotiating with the house seller, you settle on a $300,000 strike price—the price you’ll pay if you exercise the option. Regardless of the market price, you retain the right to buy at this fixed price within the contract’s timeframe.
The relationship between strike price and the current market price determines the option contract’s value.
Option Premium
The premium is the amount you pay to acquire the options contract—the cost for the right to buy or sell the underlying asset, with no obligation.
In the earlier example, this was your holding fee. Suppose you pay the seller a $5,000 non-refundable premium for the house option contract. This guarantees you can buy for $300,000, no matter the market price, within the specified period. If you decide not to buy, you forfeit the $5,000 premium.
Key factors affecting an option contract’s price include:
-
The current market price of the underlying asset
-
Volatility in the asset’s price
-
The strike price
-
The time remaining until expiration
Contract Size
Standard equity options contracts typically cover 100 shares of the underlying stock. For other types—such as index or crypto options—contract size can vary. Always review contract details before trading to know exactly how much of the underlying asset is involved.
Key Terms
There are several essential concepts to understand in options trading.
Moneyness Terms
Terms like In The Money (ITM), At The Money (ATM), and Out Of The Money (OTM) describe the relationship between the strike price and the current market price of the underlying asset. These concepts help you decide whether to exercise the contract—and, more importantly, indicate the option contract’s current value.
| Option Type |
In The Money |
At The Money |
Out Of The Money |
| Call |
Market Price > Strike Price |
Market Price = Strike Price |
Market Price < Strike Price |
| Put |
Market Price < Strike Price |
Market Price = Strike Price |
Market Price > Strike Price |
Greek Risk Metrics
In options trading, “Greeks” are risk metrics that help traders understand how various factors affect options pricing.
Each Greek letter represents a different sensitivity, allowing traders to assess risk and make informed decisions. The five primary Greeks are Delta, Gamma, Theta, Vega, and Rho.
| Greek |
Definition |
| Delta (Δ) |
Measures how much an option’s price changes for a $1 change in the underlying asset. |
| Gamma (Γ) |
Measures how much Delta changes for each $1 move in the underlying asset. |
| Theta (θ) |
Measures time decay—how much the option’s value decreases as expiration approaches. |
| Vega (ν) |
Shows sensitivity to market volatility; higher volatility usually boosts option prices. |
| Rho (ρ) |
Measures price change for a 1% change in interest rates—positive Rho means higher rates increase option prices; negative Rho means they decrease. |
American vs. European Options
This article covers options trading as it works in global financial markets, where multiple option types exist. Depending on the market and platform, you may encounter different option styles. The key distinction between the two most common types is when you can exercise them:
-
American Options: Can be exercised any time before expiration, giving holders added flexibility.
-
European Options: Can only be exercised on the expiration date.
Options on Leading Platforms
On many top trading platforms, you’ll find options contracts in both styles. Most major platforms offer European-style options, which means you can only exercise the contract at expiration. Since most options trading involves buying and selling contracts—not exercising them—this primarily affects how and when settlement occurs.
In many cases, options are exercised automatically. If your contract is in the money at expiration, you receive the payout whether or not you exercise it manually.
These contracts can also be cash-settled, so when an option is exercised, the parties exchange a cash amount rather than delivering the underlying asset. This streamlines the process and avoids complications of asset transfer.
Final Thoughts
Options trading—especially with American-style contracts—lets traders and investors buy or sell an underlying asset at a set price before expiration. By removing immediate obligation, you gain more flexibility in the financial markets.
You can also trade the options contracts themselves, without ever exercising them, to profit from changes in contract value. While options offer profit potential, it’s critical to grasp the fundamentals before you start trading.
