How is money actually made from the buying or selling of options?
"Not all call options that have value at expiration, exercise by purchasing the security (or attempting to, with funds in your account).   On ETNs, they often (always?) settle in cash.  As an example of an option I'm currently looking at, AVSPY, it settles in cash (please confirm by reading the documentation on this set of options at http://www.nasdaqomxtrader.com/Micro.aspx?id=Alpha, but it is an example of this).  There's nothing it can settle into (as you can't purchase the AVSPY index, only options on it).  You may quickly look (wikipedia) at the difference between ""American Style"" options and ""European Style"" options, for more understanding here. Interestingly I just spoke to my broker about this subject for a trade execution.  Before I go into that, let me also quickly refer to Joe's answer:  what you buy, you can sell.  That's one of the jobs of a market maker, to provide liquidity in a market.  So, when you buy a stock, you can sell it.  When you buy an option, you can sell it.  That's at any time before expiration (although how close you do it before the closing bell on expiration Friday/Saturday is your discretion).  When a market maker lists an option price, they list a bid and an ask.  If you are willing to sell at the bid price, they need to purchase it (generally speaking).  That's why they put a spread between the bid and ask price, but that's another topic not related to your question -- just note the point of them buying at the bid price, and selling at the ask price -- that's what they're saying they'll do. Now, one major difference with options vs. stocks is that options are contracts. So, therefore, we can note just as easily that YOU can sell the option on something (particularly if you own either the underlying, or an option deeper in the money).  If you own the underlying instrument/stock, and you sell a CALL option on it, this is a strategy typically referred to as a covered call, considered a ""risk reduction"" strategy.  You forfeit (potential) gains on the upside, for money you receive in selling the option. The point of this discussion is, is simply: what one buys one can sell;  what one sells one can buy -- that's how a ""market"" is supposed to work.  And also, not to think that making money in options is buying first, then selling.  It may be selling, and either buying back or ideally that option expiring worthless. -- Now, a final example.  Let's say you buy a deep in the money call on a stock trading at $150, and you own the $100 calls.  At expiration, these have a value of $50.  But let's say, you don't have any money in your account, to take ownership of the underlying security (you have to come up with the additional $100 per share you are missing).  In that case, need to call  your broker and see how they handle it, and it will depend on the type of account you have (e.g. margin or not, IRA, etc).  Generally speaking though, the ""margin department"" makes these decisions, and they look through folks that have options on things that have value, and are expiring, and whether they have the funds in their account to absorb the security they are going to need to own.  Exchange-wise, options that have value at expiration, are exercised.  But what if the person who has the option, doesn't have the funds to own the whole stock? Well, ideally on Monday they'll buy all the shares with the options you have at the current price, and immediately liquidate the amount you can't afford to own, but they don't have to.  I'm mentioning this detail so that it helps you see what's going or needs to go on with exchanges and brokerages and individuals, so you have a broader picture." Today SPY (The S&P ETF) trades at $128. The option to buy at $140 (this is a Jan '13 call) trades for $5.  I buy the call, for $500 as they trade in 100 lots.  The S&P skyrockets to 1500 and SPY to $150. The call trades for $11, as it still has a month or two before expiring, so I sell it, and get $1100. The S&P rose 17%, but I doubled my money. If it 'only' rose 9%, to less than $140, I'd lose my investment. No, I don't need to buy the SPY I can sell the call any time before expiration. In fact, most options are not exercised, they are sold between purchase and expiration date.
You can make money via stocks in two primary ways: Note that there's no guarantee of either. So it may very well not make you money. There are indeed various strategies to make money from this. As Ben correctly said, the stock price drops correspondingly on the dividend date, so the straightforward way doesn't work. What does work are schemes that involve dividend taxation based on nationality, and schemes based on American Options where people can use market rules to their advantage if some options are not exercised. "A company has 100,000 shares and 100,000 unexercised call options (company issued). Share price and strike price both at $1. What country is this related to?   I ask because, in the US, most people I know associate a ""call"" option with the instrument that is equivalent to 100 shares.   So 100,000 calls would be 10,000,000 shares, which exceeds the number of shares you're saying the company has.   I don't know if that means you pulled the numbers out of thin air, or whether it means you're thinking of a different type of option? Perhaps you meant incentive stock options meant to be given to employees?  Each one of those is equivalent to a single share.  They just aren't called ""call options"". In the rest of my answer, I'm going to assume you meant stock options. I assume the fact that these options exist will slow any price increases on the underlying shares due to potential dilution? I don't think the company can just create stock options without creating the underlying shares in the first place.  Said another way, a more likely scenario is that company creates 200,000 shares and agrees to float 50% of them while reserving the other 50% as the pool for incentive employee stock.  They then choose to give the employees options on the stock in the incentive pool, rather than outright grants of the stock, for various reasons.  (One of which is being nice to the employees in regards to taxes since there is no US tax due at grant time if the strike price is the current price of the underlying stock.) An alternative scenario when the company shares are liquidly traded is that the company simply plans to buy back shares from the market in order to give employees their shares when options are exercised.  In this case, the company needs the cash on hand, or cash flow to take money from, to buy those shares at current prices. Anyway, in either case, there is no dilution happening WHEN the options get exercised.  Any dilution happened before or at the time the options were created.   Meaning, the total number of shares in the company was already pre-set at an earlier time.  As a result, the fact that the options exist in themselves will not slow price changes on the stock. However, price changes will be impacted by the total float of shares in the company, or the impact to cash flow if the company has to buy shares to redeem its option commitments.   This is almost the same thing you're asking about, but it is technically different as to timing. If this is the case, can this be factored into any option pricing models like black-scholes? You're including the effect just by considering the total float of shares and net profits from cash flow when doing your modelling." Let's say a stock trades at $100 right now, and you can buy a $100 call option. When you buy the call option (and the money you paid is gone), one of two things can happen: The share price goes up, or the share price goes down.  If the share price goes up, you profit. If the share price goes down, you don't lose! Because once the shares are below $100, you don't exercise the call option, and you don't lose any money.  So if you have a share that is rock solid at $100, you don't make money. If you have a share where the company owner took some ridiculous risk, and the shares could go to $200 or the company could go bankrupt, then you have a 50% chance to make $100 and a 50% chance to not lose anything. That's much more preferable. The nature of options requires you to understand that they are essentially a bet. In one sense, so is investing in stocks. We imagine a bell curve (first mistake) with a median return at 10%/yr and a standard deviation of about 14%. Then we say that odds are that over some period of time a monte-carlo simulation can give us the picture of the likely returns.  Now, when you buy short term options, say one month or so, you are hoping the outcome is a rise in price that will yield some pretty high return, right?  There was a time I noticed a particular stock would move a large percent based on earnings. And earnings were a day before options expiration. So I'd buy the call that was just out of the money and if the surprise was up, I'd make 3-4X my money. But I was always prepared to lose it all and often did. I never called this investing.  I know of no recovery strategy. Sorry. Think of options as insurance. An insurance company makes money by selling the policies at a rate slightly higher than the average payout.  Most options expire worthless. This is because most options are purchased by hedge funds. To 'hedge' means taking out insurance in case your position goes against you. So the sellers of options obtain a price that covers their (averaged) losses plus provides them with a profit for their trouble.  An option has an amount that it declines in value each day (called theta). At the expiration date the option is worth zero (if it is out-of-the-money). So it is option writers that, typically, make money in the options market (as they are the sellers of insurance). If they didn't make money selling options they would not sell them.  For example, the February call option on SPY strike 200 traded at 8.81 on 12/30. Since then it has crumbled in value to 0.14. The option writer currently stands to make a huge profit.  So, just as with insurance, you (generally) never make money by buying insurance. But the sellers of insurance tend to make money as do the writers of options.  Edit: Theta @ Investopedia You'd likely be most familiar with them with respect to options and futures on commodities but they're used for credit/interest as well. The intrinsic value of an option is *derived* from the spread between call/put price and strike price; the value of the contract I've paid for or sold is derived from the current market value of the underlying asset, be it rice, platinum, or the Swedish kroner The product itself is a derivative as it derives its value from another stock or commodity.  It's similar to a US option, which offers (in the case of a 'call') the right, but not the obligation to buy a stock at a predetermined price before a certain date. But, unlike the US option, instead of buying the stock, the contract is only closed out in cash. I've made the analogy to betting, so I believe it to be a fair comparison. I hope this question is theoretical. You should never buy a financial instrument with no clue how it works. "In real life, you'd see spreads like AMZN 04/13/2017 910.00 C 4.90 +1.67 Bid: 4.75 Ask: 5.20 (with AMZN @ $897 right now) and the fill you'd get on the buy side would be closer to the ask. i.e. I'd offer $5.00 and hope that it filled.  Filling a $4 bid when ask is $8 isn't likely unless the stock blipped down enough for your price to fill.  Options are a lot like day trading, in most cases. Most members here will agree that day trading isn't investing, it's gambling. Long term, the S&P has been up 10%/yr. But any given day, the noise of the market is a 50/50 zero sum game. Most long term stock 'investors' do well. Those who get in and out, not so much.  There are aspects to options that are appealing. As you've seen, the return can be high, even IRL, but your loss can be 100% as well. Let me share with you a blurred line - I wrote ""Betting on Apple at 9 to 2"" in which I described an option strategy that ran 2 years and would return $10,000 on a $2200 bet. A similar bet that ended a year ago yielded a 100% loss. I don't post there very often, as I keep that trading to a minimum.  There are warnings for those who want to start trading options -" An option, by definition, is a guess about the future value of the stock. If you guess too aggressively, you lose the purchase price of the option; if you guess too conservatively, you may not take the option or may not gain as much as you might have. You need to figure out what you expect to happen, and how confident you are about it, against the cost of taking the option -- and be reasonably confident that the change in the stock's value will be at least large enough to cover the cost of buying into the game. Opinion: Unless you're comfortable with expectation values and bell curves around them, it's significantly easier to lose money on options than to profit on them. And I'm not convinced that even statisticians can really do this well. I've always been told that the best use for options is hedging an investment you've already made; treating them as your primary bet is gambling, not investment. "Suddenly its not just comparing the current price to the price of the contract, or is it? Sure it is.  Suppose you bought 100 option contracts (each for 100 shares) and paid a $1 per share premium ($10,000 total).  Now those options are trading for $1.50 per share.  You have an unrealized $0.50 gain per share, or $5,000. The $10,000 in options you bought are now worth $15,000.  It holds whether they were bought to open or close a position, or whether they are puts or calls.  The only difference is whether you bought or sold the options (the arithmetic is just reversed for selling an option). But lets say we have an Option, where the payoff is max(St-K, c0) where ct is the market price. What do you do then? Your current, unrealized P&L is different than the payoff.  The payoff only happens at maturity.  The current P&L is based on current market prices, just like stock.  Option prices all have a ""time premium"" making them worth more than their payoff (intrinsic) value prior to maturity." "I'm adding to @Dilip's basic answer, to cover the additional points in your question.  I'll assume you are referring to publicly traded stock options, such as those found on the CBOE, and not an option contract entered into privately between two specific counterparties (e.g. as in an employer stock option plan). Since you are not obligated to exercise a call option you purchased on the market, you don't need to maintain funds on account for possible exercising.  You could instead let the option expire, or resell the option, neither of which requires funds available for purchase of the underlying shares. However, should you actually choose to exercise the call option (and usually this is done close to expiration, if at all), you will be required to fund your account much like if you bought the underlying shares in the first place.  Call your broker to determine the exact rules and timing for when they need the money for a call-option exercise. And to expand on the idea of ""cancelling"" an option you purchased: No, you cannot ""cancel"" an option contract, per se.  But, you are permitted to sell the call option to somebody else willing to buy, via the market.  When you sell your call option, you'll either make or lose money on the sale – depending on the price of the underlying shares at the time (are they in- or out- of the money?), volatility in the market, and remaining time value.  Once you sell, you're back to ""no position"".  That's not the same as ""cancelled"", but you are out of the trade, whether at profit or loss. Furthermore, the option writer (i.e. the seller who ""sold to open"" a position, in writing the call in the first place) is also not permitted to cancel the option he wrote.  However, the option writer is permitted to close out the original short position by simply buying back a matching call option on the market.  Again, this would occur at either profit or loss based on market prices at the time.  This second kind of buy order – i.e. made by someone who initially wrote a call option – is called a ""buy to close"", meaning the purchase of an offsetting position.  (The other kind of buy is the ""buy to open"".) Then, consider: Since an option buyer is free to re-sell the option purchased, and since an option writer (who ""sold to open"" the new contract) is also free to buy back an offsetting option, a process known as clearing is required to match remaining buyers exercising the call options held with the remaining option writers having open short positions for the contract.  For CBOE options, this clearing is performed by the Options Clearing Corporation.  Here's how it works (see here): What is the OCC? The Options Clearing Corporation is the sole issuer of all securities   options listed at the CBOE, four other U.S. stock exchanges and the   National Association of Securities Dealers, Inc. (NASD), and is the   entity through which all CBOE option transactions are ultimately   cleared. As the issuer of all options, OCC essentially takes the   opposite side of every option traded. Because OCC basically becomes   the buyer for every seller and the seller for every buyer, it allows   options traders to buy and sell in a secondary market without having   to find the original opposite party.   [...]   [emphasis above is mine] When a call option writer must deliver shares to a call option buyer exercising a call, it's called assignment.  (I have been assigned before, and it isn't pleasant to see a position called away that otherwise would have been very profitable if the call weren't written in the first place!) Also, re: ""I know my counter party cannot sell his shares"" ... that's not strictly true.  You are thinking of a covered call.  But, an option writer doesn't necessarily need to own the underlying shares.  Look up Naked call (Wikipedia).  Naked calls aren't frequently undertaken because a naked call ""is one of the riskiest options strategies because it carries unlimited risk"".  The average individual trader isn't usually permitted by their broker to enter such an order, but there are market participants who can do such a trade. Finally, you can learn more about options at The Options Industry Council (OIC)." I do this often with shares that I own - mostly as a learning/experience-building exercise, since I don't own enough individual stocks to make me rich (and don't risk enough to make me broke). Suppose I own 1,000 shares of X.  I don't expect my shares to go down, but I want to be compensated in case they do go down.  Sure, I could put in a stop-loss order, but another option is to sell a call above where the stock is now (out-of-the-money).   So I get the premium regardless of what happens.  From there three things can happen: So a covered call essentially lets you give up some upside for some compensation against downward moves.  Mathematically it's roughly equivalent to selling a put option - you make a little money (from the premium) if the stock goes up but can lose a lot if the stock plummets. So you would sell call options if: The first thing that I learned the hard way (by trying my hand at actual options trading) is that liquidity matters. So few people are interested in trading the same options that I am that it is easy to get stuck holding profitable contracts into expiration unless I offer to sell them for a lot less than they are worth.  I also learned that options are a kind of insurance,and no one makes money (in the long run) buying insurance.  So you can use options to hedge and thereby prevent losses, but you also blunt your gains.  Edit: IMO,options (in the long run) only make money for the brokers as you pay a commission both on the buy and on the sell. With my broker the commission on options is higher than the commission on stocks (or ETFs). "This has been answered countless times before: One example you may want to look at is DGRO.  It is an iShares ETF that many discount brokers trade for free.  This ETF:  offers ""exposure to U.S. stocks focused on dividend growth""."
