Options make money in two opposite ways depending on which side of the contract you take. Buyers pay a premium upfront for the right to buy or sell 100 shares at a set price and profit when the stock moves far enough in their direction to more than cover what they paid. Sellers collect that premium immediately and profit when the contract loses value or expires worthless, letting them keep the cash. The same contract, in other words, is a leveraged directional bet for one party and a time-and-volatility trade for the other.
How Buyers Make Money
Buying an option is a leveraged bet on direction with a capped downside. You put up a fraction of what it would cost to buy or short 100 shares, and if the stock moves your way by enough to cover the premium, everything past that point is profit. If it doesn’t, you lose what you paid and nothing more.
A call gives you the right to buy 100 shares at a fixed price, called the strike, anytime before expiration. You make money when the stock climbs above your break-even, which is the strike price plus the per-share premium. Buy a call with a $100 strike for $5 per share, and the contract costs $500 total. Your break-even is $105. If the stock reaches $115 at expiration, the contract is worth $15 per share, or $1,500, giving you $1,000 of profit on a $500 outlay. That’s a 200% return. Had you bought 100 shares outright at $100, the same $15 move would be a 15% gain. Leverage cuts both ways, though: you only see any of that upside if you’re right about direction and timing.
A put is the mirror image. It gives you the right to sell 100 shares at the strike, so you profit when the stock falls. Break-even is the strike price minus the premium. A $100-strike put bought for $5 that expires with the stock at $85 is worth $15 per share, again netting $1,000 on $500 risked. Whether you buy a call or a put, the maximum you can lose is the premium. That ceiling on losses is built into every purchased option before you place the trade.
How Sellers Make Money
Selling flips the equation. Instead of paying for a chance at a big win, you collect the premium upfront and bet nothing dramatic happens. The seller’s best outcome is for the option to expire worthless, because the entire premium then becomes profit.
Time is the seller’s advantage. Every day that passes without a significant stock move reduces the option’s value through time decay, and that erosion accelerates sharply in the last 30 days before expiration. Value bleeding out of the buyer’s position flows into the seller’s account as unrealized profit, even if the stock hasn’t moved at all. Many sellers deliberately target short-dated contracts for exactly this reason.
The risk side depends on whether the position is covered or naked. A covered call writer already owns the underlying 100 shares, so if the buyer exercises, the seller simply delivers stock they hold. The tradeoff is missing out on any gains above the strike price. A naked call seller owns no shares and is obligated to buy at whatever the market price is if assigned. Since stock prices have no upper limit, the theoretical loss on a naked call is unlimited. Naked put sellers face a related risk: if the stock crashes, they still have to buy shares at the strike price no matter how far below it the market has fallen. Brokerages require higher approval levels and substantial margin deposits before allowing naked writing.
Margin Requirements
Because sellers carry open-ended obligations, brokerages require margin deposits as a cushion. Minimum levels are set by FINRA Rule 4210 based on the value of the underlying position and how far in or out of the money the option is.1FINRA. FINRA Rule 4210 – Margin Requirements If a trade moves against you and your account drops below the required level, you’ll get a margin call demanding more cash or forcing the position closed. Covered writers face lighter requirements because their shares serve as collateral.
Early Assignment
American-style options, which cover most individual stocks and ETFs, can be exercised by the buyer anytime before expiration. As a seller, you can be assigned unexpectedly. Early assignment is most common right before a stock’s ex-dividend date, because call holders sometimes exercise early to capture the dividend when the option’s remaining time value is less than the dividend amount. If you sell options on dividend-paying stocks, watch the calendar.
What Drives an Option’s Price
An option’s premium has two components. Intrinsic value is how much the option would be worth if exercised immediately: for a call, the stock price minus the strike (if positive); for a put, the strike minus the stock price. An option with intrinsic value is called in the money. Extrinsic value is everything else in the premium, and it reflects what the market thinks could still happen before expiration.
Two forces dominate extrinsic value: time remaining and implied volatility. More time means more opportunity for the stock to move, and higher implied volatility means the market expects bigger swings. Both push premiums up. Buying an option means paying for both components. Selling one means betting extrinsic value will erode before intrinsic value grows enough to hurt you.
Time Decay
Time decay, measured by the Greek letter theta, is a one-way drain. Every calendar day reduces the time value in the premium, and the pace isn’t linear. An option with 90 days left loses time value slowly. At 30 days it accelerates. Inside the final week the decay is steep. Sellers earn most of their return in that last stretch. Buyers holding a slightly out-of-the-money option with a week to go are fighting the clock even if the stock starts moving their way.
Implied Volatility and IV Crush
Implied volatility, or IV, reflects how large the market expects future price swings to be. When IV rises, option premiums rise with it, regardless of whether the stock has actually moved. This often happens ahead of earnings announcements, FDA decisions, or other binary events. The trap for buyers comes after the event: once the uncertainty resolves, IV collapses sharply. Traders call this an IV crush. A buyer who bought a call before earnings can watch the stock move in the right direction and still lose money because the drop in implied volatility ate the extrinsic value faster than intrinsic value grew. Experienced sellers often write options during these high-IV windows, collecting inflated premiums and profiting when volatility normalizes.
Dividends
When a stock goes ex-dividend, its price drops by roughly the dividend amount. Option markets price this in ahead of time: call premiums decline and put premiums rise as the ex-dividend date approaches. If you’re holding calls through an ex-dividend date, you absorb that expected drop without collecting the dividend, because option holders don’t receive dividends.
The Bid-Ask Spread Costs You Before the Trade Moves
Every option quotes two prices: the bid (what buyers will pay) and the ask (what sellers will accept). The gap is an immediate cost. Buy a call at the ask of $5.20 when the bid is $4.80, and you start the trade $0.40 per share in the hole, or $40 per contract. On a $500 position, that’s an 8% drag before the stock moves.
Liquid options on heavily traded names have spreads of a few cents. Illiquid options on small-cap stocks or far out-of-the-money strikes can have spreads of $0.50 or more. Your real break-even is worse than the textbook number by the size of that spread. Sticking to high-volume options with tight spreads is one of the simplest ways to improve results.
How You Actually Collect the Money
A profitable option position means nothing until you close it. There are three ways to turn paper value into cash, and the most common one doesn’t involve trading any shares.
Selling to Close
Most profitable option trades end with an offsetting transaction. If you bought a call, you sell that same call on the open market. If you sold a put, you buy it back. The difference between your entry and exit prices is your profit or loss. This is simpler and more capital-efficient than exercising, because you don’t need the cash to buy 100 shares or the shares to deliver. It also captures any remaining extrinsic value, which exercise would forfeit.
Exercise and Assignment
Exercising a call means buying 100 shares at the strike. Exercising a put means selling 100 shares at the strike. When a buyer exercises, the OCC randomly assigns a seller on the other side, who must fulfill the obligation.2FINRA. Exercise Cut-Off Time for Expiring Options Exercise usually makes sense only when little extrinsic value remains, or when the holder actually wants to own or sell the shares.
One rule catches beginners: the OCC automatically exercises any option finishing at least $0.01 in the money at expiration under its exercise-by-exception process.3The Options Industry Council. Options Exercise If you own a barely in-the-money call and don’t want to buy 100 shares over the weekend, submit a do-not-exercise instruction to your broker before the cutoff.
Cash Settlement
Not every option delivers shares. Index options like SPX and VIX options settle in cash: if the option is in the money at expiration, you receive the dollar difference between the settlement value and the strike rather than any stock.4Cboe. Why Option Settlement Style Matters All equity and ETF options physically deliver shares when exercised.
Pin Risk
When a stock closes right at or near a strike price on expiration day, sellers face pin risk. You don’t know whether the buyer on the other side will exercise, and the assignment decision happens after the market closes. You can go home Friday assuming you’re done and wake up Monday with a stock position exposed to any weekend gap. Traders managing short positions near expiration usually close them before the final hour rather than gambling on where the stock pins.
What the IRS Takes
How options profits are taxed depends on the type of option, how long you held it, and whether you exercised or closed the position.
For puts and calls on individual stocks, standard capital gains rules apply. Buy an option and sell it for a profit, and the gain is short-term or long-term based on how long you held the option itself. Most options trades last less than a year, so gains are typically short-term and taxed at ordinary income rates.5Internal Revenue Service. Publication 550 – Investment Income and Expenses If you exercise a call, the premium you paid is added to the cost basis of the shares, and the holding period for those shares starts on the acquisition date, not the option’s purchase date. If you exercise a put, the premium reduces the amount realized on the share sale.
For sellers, an expired option produces a short-term capital gain equal to the premium received, regardless of how long the position was open. Closing a short option with a buyback creates a short-term gain or loss for the difference between the premium received and the cost to close.
Broad-based index options like SPX qualify as Section 1256 contracts and get a favorable split: 60% of any gain is treated as long-term and 40% as short-term, regardless of holding period.6Office of the Law Revision Counsel. 26 USC 1256 – Section 1256 Contracts Marked to Market Since long-term rates top out at 20% while ordinary rates run as high as 37%, the blended treatment can meaningfully reduce the bill. Standard equity options are explicitly excluded from Section 1256 and don’t qualify.
The wash sale rule also applies. Close an option at a loss and buy a substantially identical option within 30 days before or after, and the loss is disallowed for that year.7Investor.gov. Wash Sales The disallowed loss is added to the cost basis of the new position, so the tax benefit is deferred rather than lost. Active traders who roll losing positions can accumulate deferred losses that distort their tax picture, so track your 30-day windows if you trade the same underlying repeatedly.
Getting Approved to Trade in the First Place
You can’t open a brokerage account and start writing naked calls the next morning. Brokerages evaluate experience, finances, and risk tolerance before granting options access, and they approve you for specific strategy tiers. FINRA’s framework outlines four categories: buying puts and calls, writing covered calls, writing uncovered options, and trading spreads.8FINRA. Regulatory Notice 21-15 – Options Account Approval, Supervision and Margin Most brokerages map these to numbered levels, with Level 1 the most restrictive and Level 3 or 4 allowing naked writing.
A beginner will usually qualify for buying calls and puts and writing covered calls. Uncovered writing and complex multi-leg strategies require documented experience and higher balances. Accounts flagged as pattern day traders, meaning four or more day trades in five business days, must maintain at least $25,000 in equity at all times.9Federal Register. Self-Regulatory Organizations – FINRA Notice of Filing To Amend Rule 4210 That threshold applies to the whole account, and dropping below it triggers an immediate restriction on new trades until you deposit more funds.
