Trading options has never been easier to access. Commission-free investment platforms put these contracts a few taps away, and trading volume keeps breaking records. More than 70 million options contracts changed hands on an average trading day in the first half of 2026, according to the Options Clearing Corporation (OCC).
That easy access hides a complex product. Options can multiply your gains, shield your portfolio from a downturn, or wipe out your money faster than almost any mainstream investment. That's why it's essential to make sure you understand them before you put your money on the line.
Let's break down what options are, how a trade works from start to finish, who is behind these contracts, and what benefits and risks they present.
An option is a contract that locks in a price to buy or sell an asset for a limited time. You pay an up-front fee, or premium, for that contract. If prices move in your favor, you can cash in on your locked-in price and pocket the difference. If they don't, you can simply walk away. As the contract's buyer, your loss stops at the premium you paid.
Options belong to a family of investments called derivatives. The name fits because the contract's value derives from the price of something else. You never have to own the underlying stock or asset to trade options on it.
Standard stock options come in contracts of 100 shares each. So a premium quoted at $2 per share actually costs you $200 per contract. In addition to contract size, you'll see five terms in your contract:
Underlying asset: This is the asset tied to the contract. That's usually a stock, but options also exist on exchange-traded funds (ETFs) and market indexes.
Premium: The fee you pay for the contract itself. It's your cost of entry and the most you can lose as a buyer.
Strike price: The locked-in price where the contract lets you buy or sell the underlying asset.
Expiration date: The deadline attached to every contract. Once it passes, the option stops existing.
Exercising your option: This means using your contract to buy or sell shares at the strike price.
Every option falls into one of two categories:
Call option: A call lets its buyer purchase shares at the strike price.
Put option: A put lets its buyer sell shares at the strike price.
You buy calls when you expect a stock to rise, and buy puts when you expect it to fall or want protection against a drop.
Notice how buying and selling do double duty in options, which can trip up almost everyone at first. You buy or sell options contracts, and the contracts themselves allow you to buy or sell shares.
The two don't always point in the same direction. Put buyers purchase contracts that allow them to sell shares. When options traders talk about buyers or sellers, they typically refer to the contracts, not the underlying assets they're tied to.
That gives every trade four possible positions.
Paying for the ability to buy 100 shares at the strike price
The stock rises well above the strike price
Paying for the ability to sell 100 shares at the strike price
The stock falls well below the strike price
Collecting a premium and promising to deliver shares if asked
Collecting a premium and promising to buy shares if asked
The strike price minus the premium times 100
A call profits from rising prices. Let's say a stock trades at $50, and you buy a call with a $55 strike price for a $200 premium.
If the stock climbs to $62, your contract lets you buy 100 shares at $55 and sell them at the market price. That's a $700 gain, or $500 after the premium. If the stock never tops $55, the contract expires worthless and you lose the $200 premium.
The seller of that call collected your $200 on day one and keeps it if the contract expires. The safe way to make that trade is through a covered call, which means the seller owns the 100 shares before selling the contract. If the stock takes off, the seller hands over shares they already own at $55 per share, meaning they still profit. They just give up everything above $55.
Selling the same call without owning the shares is riskier. The seller has to buy shares at whatever the market charges just to deliver them at $55, and since a stock has no ceiling, neither does the loss. Traders call this an uncovered call.
A put profits from falling prices, which makes it a natural insurance tool. Take the same $50 stock, but this time you own 100 shares and worry about a crash, so you buy a $45 put for a $150 premium.
If the stock drops to $38, your contract still lets you sell at $45. The put just cut your loss from $1,200 to $650 that includes $500 in share losses plus the $150 premium. If the crash never happens, the put expires and you lose the $150 premium, the same way an insurance premium is gone after a claim-free year.
The seller of that put acts as the insurer. Most regular investors who sell puts keep enough cash on hand to buy the shares, a setup traders call a cash-secured put. If the stock holds above $45, the contract expires and the seller keeps the $150 premium. If it crashes, the seller must buy 100 shares from the put buyer at $45. Traders call that moment "assignment," when the clearinghouse taps a seller to complete a deal a buyer has exercised.
That deal isn't as bad as it sounds. Put sellers usually target stocks they'd be happy to own, so a crash hands them shares below the old price, plus $150 for their patience. The loss can grow deep if the company truly collapses, but unlike the uncovered call, it has a floor.
Trading options starts the way most investing does, with a brokerage account and an opinion about where a stock is headed. Here's how you can start your first options trade:
Open an approved account: Regular brokerage accounts don't include options. After you apply, brokers review your experience and finances, then assign you an approval level. Entry tiers allow tamer strategies like buying calls and puts, while higher levels unlock riskier trades like uncovered calls.
Pick an underlying asset: This is the stock or ETF your contract will track. Heavily traded names come with busier options markets, which keep prices fair and exits easy.
Choose a call or a put: Calls express a bullish view, meaning you expect the price to rise. Puts express the bearish opposite or add protection to shares you already own.
Select a strike price and expiration date: These two choices set your odds and your cost. Premiums increase as strikes get closer to the current price and as expiration dates stretch further out.
Pay the premium: Quotes appear per share, so multiply by 100 for your real cost. A $1.50 quote means $150 per contract.
Choose your exit: You can exercise the contract, sell it to another trader, or let it expire and lose the premium.
Timing that exit is an important part of every trade. An option loses a little value every day the stock stands still, and the erosion speeds up as expiration nears. Traders call this time decay, and it works against buyers and for sellers on every contract.
That's one reason many traders never touch the underlying shares at all. They buy a cheap contract, watch its value rise as the stock moves, then sell the contract for a profit before the clock does its damage. The option itself becomes the asset they trade.
Standard stock and ETF options are known as listed options, because they trade on public exchanges under uniform rules rather than in private deals. This public market began when the Chicago Board Options Exchange opened in 1973 as the first U.S. exchange to trade listed options. On day one, traders swapped just 911 call contracts tied to 16 stocks. Today, multiple exchanges compete for options volume.
Underneath all the trades, the Options Clearing Corporation serves as the safety net for the listed options market. It stands between buyers and sellers and makes sure each side honors the deal. This clearinghouse currently supports 21 exchanges and trading platforms.
Many investing platforms allow you to access this market for a small fee once you pass their application. Charles Schwab and Fidelity charge $.65 per options contract, while Robinhood offers commission-free trades on stock and ETF options, though small regulatory fees still pass through.
Used with discipline, options solve problems that plain stock ownership can't:
Defined risk when you buy: The moment you pay a premium, you know your worst-case scenario to the dollar. A stockholder can watch losses deepen for years with no clear bottom. An options buyer knows the bottom before the trade even opens.
Big results from small amounts: A $200 call on a $50 stock gives you a stake in 100 shares worth $5,000, leaving the rest of your cash free for other investments. The catch is discipline, since losses from cheap contracts can quickly pile up.
Income from shares you already own: Selling covered calls turns stocks you already own into a source of cash. For example, you can collect $50 for a month-long contract on a $5,000 holding and repeat the trade to end up with a few hundred dollars a year. The trade-off is that if the stock surges past your strike price, you must sell your shares to the buyer and give up the extra gains.
Insurance against a crash: A put locks in a selling price for shares you own. However far the stock falls, you can still sell at the price you chose. If the fall never comes, the contract expires, and the premium bought you peace of mind rather than a payout.
Profit in any direction: You can only profit from stocks you buy when their price increases. Options allow you to profit in two more directions. Puts make money when prices fall, and sellers collect premiums from contracts that expire.
The same features that let you benefit from options also create ways to lose money that stocks don't have:
Time can eat at a contract's value: Stockholders can wait out a slow stretch, but options traders work against time. A strong move in your favor can outrun the decay, but a stock that drifts sideways leaves your contract worth less each day.
Losing the full premium is common: A stock rarely goes to zero, but contracts expire worthless all the time. For buyers, the damage stops at the premium. That's exactly why you shouldn't invest what you can't afford to lose.
Sellers can owe far more than they earned: Collect $200 for an uncovered call, and a sharp rally can turn it into thousands in losses. Assignment rarely announces itself either. A seller can wake up obligated to buy or deliver shares at a painful price.
Being right isn't always enough: The premium raises your bar for profit. If you pay $2 per share for a $55 call, the stock must clear $57 before you make any profit.
The price gap adds a cost to every trade: Buyers offer one price, sellers ask another, and the gap between them is called the spread. On rarely traded contracts, it can get wide. If you buy at $1.05 and sell at $0.95, you lose about 10% before the stock moves.
Options aren't the only way to invest with amplified buying power, and they're sometimes confused with their cousins (see chart).
Here's how options stack up against stock, futures, and margin trading.
A contract giving you the choice to buy or sell an asset
A binding agreement to buy or sell an asset
Shares bought partly with a broker's loan
A premium, usually a fraction of the share cost
Part of the share price, plus ongoing interest
Buying a share makes you a part owner of a business. Buying an option is a bet on the share's price, with a deadline attached. This means that an option doesn't give you dividends or voting rights.
Buying 100 shares of a $50 stock costs $5,000, and a $12 climb earns you $1,200, a 24% gain. A $200 call on that same stock turns the same climb into roughly $500, a 150% gain on far less money. However, a flat stock costs the shareholder nothing, but costs the option buyer the entire premium.
Options on ETFs work exactly like options on individual stocks. They just let traders bet on or protect against moves in an entire market rather than one company.
Options and futures belong to the same derivative family, and both carry deadlines. The difference between them comes down to obligation. An options buyer can always walk away and lose only the premium. A futures contract binds both sides to complete the trade at the settlement date, no matter how badly it has gone for one of them.
Futures traders also post a cash deposit rather than paying a premium, and gains and losses settle against their account daily. That structure suits the professionals who dominate the market, like farmers locking in crop prices and funds protecting large portfolios.
Margin trading is a common way to control more stock than your cash covers. Your broker lends you part of the purchase. For example, $5,000 of your own money could buy $10,000 worth of shares, meaning a 20% rise in the stock becomes a 40% gain on your money, and a 20% drop becomes a 40% loss. The loan also charges interest for as long as you hold it, and if the shares fall far enough, your broker can demand more cash or sell your shares to cover the loan.
The cost of options works differently. You pay one known premium up front, and no further charges follow. Nobody can force you to add money on an option you bought outright, since you paid in full. The disadvantage is the expiration date. Shares bought on margin can sit through a downturn and recover. An option that expires during that downturn loses its entire value.
Premiums on contracts far from the stock's current price can cost under $50. Those low prices reflect low odds, so treat them as long shots rather than bargains. A more realistic starting point runs a few hundred dollars per contract on heavily traded names.
Not as a buyer. Your maximum loss equals the premium plus small broker and regulatory fees, and you know that number before you click "buy." Selling options is a different story, since a seller's losses can grow far beyond the premium they collected.
No, employee stock options have nothing to do with options trading. Companies grant them as compensation, set their own terms, and release them on their own schedules. They also never trade on public exchanges, while listed options follow standardized rules that anyone can trade under. If your employer granted you stock options, you can find details about how they work in your stock option plan documents.
