Why does a long/purchased call option have a long position in the option itself?
"It will be helpful to establish some definitions: Long ""Long"" is financial slang for ""to have possession of an asset"", legally, and ""to debit an asset"", financially.   Short ""Short"" is financial slang for ""to be liable for an asset"", legally, and ""to credit an asset"", financially. Option ""Option"" is financial slang for ""to have the right but not obligation to force the liable to perform action"", legally.  Without limits and when taken to absurdity, this can mean slavery.  For equities, this means ""to have the right but not the obligation to force the liable to buy/sell a specified asset at a specified price with a specified expiration for that right"" for a call/put, respectively. By the above, a call option is ""the right but not the obligation to force the liable to buy a specified asset at a specified price with a specified expiration for that right"". By the definition of ""long"" above, a call option is actually not long the underlying. By the definitions above and with a narrower scope applied to equities & indexes, to be ""long"" the call means ""to have the right but not the obligation to force the liable to buy a specified asset at a specified price with a specified expiration for that right"" while to be ""short"" the call means ""to have the obligation to be forced to sell a specified asset at a specified price with a specified expiration for that right"". So, to be ""long"" a call means to simply own the call." Being long the call is being long the option. The call is a type of option. A put is a type of option If you buy a call, you are long an option and long the underlying asset. If you buy a put, you are long an option and short the underlying asset. If it helps you to think about it, long is equivalent to betting for the upside and short is equivalent to betting for the downside. If you are long on options, then you expect the value of such options to increase.  If you are long an option, then you own the option.  If you are short an option, then generally you sold the option.  Someone who is short a call (sometimes called the writer or occasionally the issuer) has sold a call option to someone who is now long a call. Buying a call option that will increase in value is itself a form of investment, just as it's investment to buy stock or other instruments hoping they will appreciate in value.  An option's value will rise or fall with the underlying, so being long an option is a way to be long in the underlying.  Someone can be long in a stock by buying the stock, or long in a call by buying call options in the stock.  The long call generally requires less initial investment than buying the underlying, and lets the option-holder avoid the asset downside during the option term.  The risk is that the asset may not appreciate to the point that the call option will pay off. In the conceptual sense, a share of stock is a particular right to the profits and assets of a corporation, both in form of dividends and in liquidation.  An option is a particular right to the the share of stock.  It's just a further way to formalize and subdivide the various property rights that exist in a corporation.  If you can buy a piece of paper with particular rights to corporate profits and assets, then you can buy another piece of paper with particular rights to the former piece of paper.
First off, you should phone your broker and ask them just to be 100% certain. You will be exercised on the short option that was in the money. It is irrelevant that your portfolio does not contain AAPL stock. You will simply be charged the amount it costs to purchase the shares that you owe. I believe your broker would just take this money from your margin/cash account, they would not have let you put the position on if your account could not cover it. I can't see how you having a long dated 2017 call matters. You would still be long this call once assignment of the short call was settled. "Being ""Long"" something means you own it.  Being ""Short"" something means you have created an obligation that you have sold to someone else.  If I am long 100 shares of MSFT, that means that I possess 100 shares of MSFT.  If I am short 100 shares of MSFT, that means that my broker let me borrow 100 shares of MSFT, and I chose to sell them.  While I am short 100 shares of MSFT, I owe 100 shares of MSFT to my broker whenever he demands them back.  Until he demands them back, I owe interest on the value of those 100 shares.  You short a stock when you feel it is about to drop in price.  The idea there is that if MSFT is at $50 and I short it, I borrow 100 shares from my broker and sell for $5000.  If MSFT falls to $48 the next day, I buy back the 100 shares and give them back to my broker.  I pocket the difference ($50 - $48 = $2/share x 100 shares = $200), minus interest owed.  Call and Put options.  People manage the risk of owning a stock or speculate on the future move of a stock by buying and selling calls and puts.  Call and Put options have 3 important components.  The stock symbol they are actionable against (MSFT in this case), the ""strike price"" - $52 in this case, and an expiration, June.  If you buy a MSFT June $52 Call, you are buying the right to purchase MSFT stock before June options expiration (3rd Saturday of the month).  They are priced per share (let's say this one cost $0.10/share), and sold in 100 share blocks called a ""contract"".  If you buy 1 MSFT June $52 call in this scenario, it would cost you 100 shares x $0.10/share = $10.  If you own this call and the stock spikes to $56 before June, you may exercise your right to purchase this stock (for $52), then immediately sell the stock (at the current price of $56) for a profit of $4 / share ($400 in this case), minus commissions.  This is an overly simplified view of this transaction, as this rarely happens, but I have explained it so you understand the value of the option.  Typically the exercise of the option is not used, but the option is sold to another party for an equivalent value.  You can also sell a Call.  Let's say you own 100 shares of MSFT and you would like to make an extra $0.10 a share because you DON'T think the stock price will be up to $52/share by the end of June.  So you go to your online brokerage and sell one contract, and receive the $0.10 premium per share, being $10.  If the end of June comes and nobody exercises the option you sold, you get to keep the $10 as pure profit (minus commission)!  If they do exercise their option, your broker makes you sell your 100 shares of MSFT to that party for the $52 price.  If the stock shot up to $56, you don't get to gain from that price move, as you have already committed to selling it to somebody at the $52 price.  Again, this exercise scenario is overly simplified, but you should understand the process.  A Put is the opposite of a Call.  If you own 100 shares of MSFT, and you fear a fall in price, you may buy a PUT with a strike price at your threshold of pain.  You might buy a $48 June MSFT Put because you fear the stock falling before June.  If the stock does fall below the $48, you are guaranteed that somebody will buy yours at $48, limiting your loss.  You will have paid a premium for this right (maybe $0.52/share for example).  If the stock never gets down to $48 at the end of June, your option to sell is then worthless, as who would sell their stock at $48 when the market will pay you more?  Owning a Put can be treated like owning insurance on the stock from a loss in stock price.  Alternatively, if you think there is no way possible it will get down to $48 before the end of June, you may SELL a $48 MSFT June Put.  HOWEVER, if the stock does dip down below $48, somebody will exercise their option and force you to buy their stock for $48.  Imagine a scenario that MSFT drops to $30 on some drastically terrible news.  While everybody else may buy the stock at $30, you are obligated to buy shares for $48.  Not good!  When you sold the option, somebody paid you a premium for buying that right from you.  Often times you will always keep this premium.  Sometimes though, you will have to buy a stock at a steep price compared to market.  Now options strategies are combinations of buying and selling calls and puts on the same stock.  Example -- I could buy a $52 MSFT June Call, and sell a $55 MSFT June Call.  I would pay money for the $52 Call that I am long, and receive money for the $55 Call that I am short.  The money I receive from the short $55 Call helps offset the cost of buying the $52 Call.  If the stock were to go up, I would enjoy the profit within in $52-$55 range, essentially, maxing out my profit at $3/share - what the long/short call spread cost me.  There are dozens of strategies of mixing and matching long and short calls and puts depending on what you expect the stock to do, and what you want to profit or protect yourself from.  A derivative is any financial device that is derived from some other factor.  Options are one of the most simple types of derivatives.  The value of the option is derived from the real stock price.  Bingo?  That's a derivative.  Lotto?  That is also a derivative.  Power companies buy weather derivatives to hedge their energy requirements.  There are people selling derivatives based on the number of sunny days in Omaha.  Remember those calls and puts on stock prices?  There are people that sell calls and puts based on the number of sunny days in Omaha.  Sounds kind of ridiculous -- but now imagine that you are a solar power company that gets ""free"" electricity from the sun and they sell that to their customers.  On cloudy days, the solar power company is still on the hook to provide energy to their customers, but they must buy it from a more expensive source.  If they own the ""Sunny Days in Omaha"" derivative, they can make money for every cloudy day over the annual average, thus, hedging their obligation for providing more expensive electricity on cloudy days.  For that derivative to work, somebody in the derivative market puts a price on what he believes the odds are of too many cloudy days happening, and somebody who wants to protect his interests from an over abundance of cloudy days purchases this derivative.  The energy company buying this derivative has a known cost for the cost of the derivative and works this into their business model.  Knowing that they will be compensated for any excessive cloudy days allows them to stabilize their pricing and reduce their risk.  The person selling the derivative profits if the number of sunny days is higher than average.  The people selling these types of derivatives study the weather in order to make their offers appropriately.  This particular example is a fictitious one (I don't believe there is a derivative called ""Sunny days in Omaha""), but the concept is real, and the derivatives are based on anything from sunny days, to BLS unemployment statistics, to the apartment vacancy rate of NYC, to the cost of a gallon of milk in Maine.  For every situation, somebody is looking to protect themselves from something, and somebody else believes they can profit from it.  Now these examples are highly simplified, many derivatives are highly technical, comprised of multiple indicators as a part of its risk profile, and extremely difficult to explain.  These things might sound ridiculous, but if you ran a lemonade stand in Omaha, that sunny days derivative just might be your best friend..." "I can't speak authoritatively to your broader question about stocks in general, but in several years tracking AAPL closely, I can tell you that there's little apparent pattern to when their earnings call will be, or when it will be announced. What little I do know:  - AAPL's calls tend to occur on a Tuesday more than any other day of the week  - it's announced roughly a month in advance, but has been announced w/ less notice  - it has a definite range of dates in which it occurs, typically somewhere in the 3rd week of the new quarter plus or minus a few days More broadly for #1: Given the underlying nature of what an option is, then yes, the day an earnings call date is announced could certainly influence the IV/price of options - but only for options that expire inside the ""grey area"" (~2 weeks long) window in which the call could potentially occur.  Options expiring outside that grey area should experience little to no price change in reaction to the announcement of the date - unless the date was itself surprising, e.g. an earlier date would increase the premium on earlier dated options, a later date would increase the premium for later-dated options. As for #2: The exact date will probably always be a mystery, but the main factors are:  - the historical pattern of earnings call dates (and announcements of those dates) which you can look up for any given company  - when the company's quarter ends  - potentially some influence in how long it takes the company to close out their books for the quarter (some types of businesses would be faster than others)  - any special considerations for this particular quarter that affect reporting ability And finally:   - a surprise of an earnings call occurring (substantively) later than usual is rarely going to be a good sign for the underlying security, and the expectation of catastrophe - while cratering the underlying - may also cause a disproportionate rise in IVs/prices due to fear" Firstly, going short on a stock and worrying if the price suddenly gaps up a lot due to good news is the same as being long on a stock and worrying that the price will suddenly collapse due to bad news. Secondly, an out of the money call option would be cheaper than an in the money call option, in fact the further out of the money the cheaper the premium will be, all other things being equal. So a good risk management strategy would be to set your stop orders as per your trading plan and if you wish to have added protection in case of a large gap is to buy a far out of the money call option. The premium should not be too expensive. Something you should also consider is the time until expiry for the option, if your time frame for trading is days to weeks you make consider a cheaper option that expires in about a month, but if you are planning on holding the position for more than a month you might need a longer expiry period on the option, which will increase the premium. Another option to consider, if your broker offers it, is to use a guaranteed stop loss order. You will pay a little premium for this type of order and not all brokers offer it, but if it is offered you will be protected against any price gaps past your guaranteed stop loss price. "A covered call risks the disparity between the purchase price and the potential forced or ""called"" sale price less the premium received. So buy a stock for $10.00 believing it will drop you or not rise above $14.00 for a given period of days. You sell a call for a $1.00 agreeing to sell your stock for $14.00 and your wrong...the stock rises and at 14.00 or above during the option period  the person who paid you the $1.00 premium gets the stock for a net effective price of $15.00. You have a gain of 5$. Your hypothecated loss is unlimited in that the stock could go to $1mil a share. That loss is an opportunity loss you still had a modest profit in actual $. The naked call is a different beast. you get the 1.00 in commission to sell a stock you don't own but must pay for that right. so lets say you net .75 in commission per share after your sell the option. as long as the stock trades below $14.00 during the period of the option you sold your golden. It rises above the strike price you must now buy that stock at market to fill the order when the counter party choses to exercise the option which results in a REAL loss of 100% of the stocks market price less the .75 a share you made.   in the scenarios a 1000 shares that for up $30.00 a share over the strike price make you $5,000 in a covered call and lose you $29,250 in a naked call.Naked calls are speculative. Covered calls are strategic." On expiry, with the underlying share price at $46, we have : You ask :  How come they substract 600-100. Why ? Because you have sold the $45 call to open you position, you must now buy it back to close your position.  This will cost you $100, so you are debited for $100 and this debit is being represented as a negative (subtracted); i.e., -$100 Because you have purchased the $40 call to open your position, you must now sell it to close your position.  Upon selling this option you will receive $600, so you are credited with $600 and this credit is represented as a positive (added) ; i.e., +$600. Therefore, upon settlement, closing your position will get you $600-$100 = $500.  This is the first point you are questioning.   (However, you should also note that this is the value of the spread at settlement and it does not include the costs of opening the spread position, which are given as $200, so you net profit is $500-$200 = $300.) You then comment :  I know I am selling 45 Call that means : As a writer: I want stock price to go down or stay at strike. As a buyer: I want stock price to go up. Here, note that for every penny that the underlying share price rises above $45, the money you will pay to buy back your short $45 call option will be offset by the money you will receive by selling the long $40 call option.  Your $40 call option is covering the losses on your short $45 call option. No matter how high the underlying price settles above $45, you will receive the same $500 net credit on settlement.  For example, if the underlying price settles at $50, then you will receive a credit of $1000 for selling your $40 call, but you will incur a debit of $500 against for buying back your short $45 call.  The net being $500 = $1000-$500.  This point is made in response to your comments posted under Dr. Jones answer. In the money puts and calls are subject to automatic execution at expiration. Each broker has its own rules and process for this.  For example, I am long a put. The strike is $100. The stock trades at the close, that final friday for $90. I am out to lunch that day. Figuratively, of course. I wake up Saturday and am short 100 shares. I can only be short in a margin account. And similarly, if I own calls, I either need the full value of the stock (i.e. 100*strike price) or a margin account.  I am going to repeat the key point. Each broker has its own process for auto execution. But, yes, you really don't want a deep in the money option to expire with no transaction.  On the flip side, you don't want to wake up Monday to find they were bought out by Apple for $150. In the scenario you describe, and really, in any scenario, by the nature of how option contracts work: a higher strike put will necessarily be more expensive than the lower strike put (everything else being equal). the lower strike call will necessarily be more expensive than the higher strike call (everything else being equal). In put options, the buyer has the right to sell stock for the strike price. So the higher the strike price, the more money the buyer of the put option can make by selling the shares of stock at a higher price. In call options, it's the exact opposite: buyers of the call option have the right to buy stock at the strike price. The lower the strike price, the better for the buyer: they have the right to buy stock for a lower amount of money. So it must be worth more.
