Can you explain this options calls & puts quote table to me?
(Note: I am omitting the currency units.  While I strongly suspect it's US$ I don't know from the chart.  The system works the same no matter what the currency.) A call or a put is the right to sell (put) or buy (call) shares at a certain price on a certain day. This is why you see a whole range of prices.  Not all possible stock values are represented, the number of possibilities has to be kept reasonable.  In this case the choices are even units, for an expensive stock they may be spaced even farther apart than this. The top of the chart says it's for June.  It's actually the third Friday in the month, June 15th in this case.  Thus these are bets on how the stock will move in the next 10 days. While the numbers are per share you can only trade options in lots of 100. The left side of the chart shows calls.  Suppose you sell a call at 19 (the top of the chart)  The last such trade would have gotten you a premium of 9.70 per share (the flip side of this is when the third friday rolls around it will most likely be exercised and they'll be paying you only 19 a share for a stock now trading at something over 26.)  Note the volume, bid and ask columns though--you're not going to get 9.70 for such a call as there is no buyer.  The most anybody is offering at present is 7.80 a share. Now, lets look farther down in the chart--say, a strike price of 30.  The last trade was only .10--people think it's very unlikely that FB will rise above 30 to make this option worthwhile and thus you get very little for being willing to sell at that price.  If FB stays at 26 the option will expire worthless and go away.  If it's up to 31 when the 15th rolls around they'll exercise the option, take your shares and pay you 30 for them.  Note that you already gave permission for the trade by selling the call, you can't back out later if it becomes a bad deal. Going over to the other side of the chart with the puts: Here the transaction goes the other way, come the 15th they have the option of selling you the shares for the strike price.  Lets look at the same values we did before.  19?  There's no trading, you can't do it. 30?  Here you will collect 3.20 for selling the put.  Come the 15th they have the right to sell you the stock for 30 a share.  If it's still 26 they're certainly going to do so, but if it's up to 31 it's worthless and you pocket the 3.20 Note that you will normally not be allowed to sell a call if you don't own the shares in question.  This is a safety measure as the risk in selling a call without the stock is infinite.  If the stock somehow zoomed up to 10,000 when the 15th rolls around you would have to come up with the shares and the only way you could get them is buy them on the open market--you would have to come up with a million dollars.  If there simply aren't enough shares available to cover the calls the result is catastrophic--whoever owns the shares simply gets to dictate terms to you.  (And in the days of old this sometimes happened.)
"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..." "you bet that a quote/currency/stock market/anything will rise or fall within a period of time. ... So, what is the relationship with trading ? I see no trading at all since I don't buy or sell quotes. So, if you just wander in and say ""oh, hey, look, a bunch of options, i'm going to play games and have excitement"" then that is, in fact, some sort of gambling. Indeed, most trading activities will be like that to you. On the other hand, you might be engaged in other business where those things matter. You might be doing a lot of trading elsewhere in the market, for instance, and suddenly everyone freaks out and the stock market goes crazy and you lose a ton of money. To protect yourself from losing a ton of money, you might buy a binary option based on VIX (the volatility index) going over a certain level. If you're not in a business where you're buying it to protect yourself, then you should probably only buy the options if you have reason to think it'll be profitable and worth the risk. If you don't understand the risks, skip it." "Firstly ""Most option traders don't want to actually buy or sell the underlying stock."" THIS IS COMPLETELY UTTERLY FALSE Perhaps the problem is that you are only familiar with the BUY side of options trading. On the sell side of options trading, an options desk engages in DELTA HEDGING. When we sell an option to a client. We will also buy an appropriate amount of underlying to match the delta position of the option. During the life time of the option. We will readjust our hedge position whenever the delta changes (those who follow Black Scholes will know that normally that comes from (underlying) price changes). However, we lose money on each underlying change (we have to cross the bid-ask spread for each trade). That is why we lose money when there is volatility. That is why we are said to be ""short VEGA"" or ""short volatility"". So one way to think about ""buying"" options, is that you are paying someone to execute a specific trading strategy. In general, those who sell options, are also happy to buy options back (at a discount of course, so we make a profit). But when doing so, we need to unroll our hedging position, and that again incurs a cost (to us, the bank). Finally. Since this is ""money"" stackexchange rather than finance. You are most likely referring to ""warrants"" rather than ""options"", which are listed on stock exchanges. The exchange in most regions give us very specific and restrictive regulations that we must abide by. One very common one is that we MUST always list a price which we are willing to buy the warrants back at (which may not be an unreasonable spread from the sell price). Since an Option is a synthetically created investment instrument, when we buy back the Option from the investor, we simply unwind the underlying hedging positions that we booked to synthesize the Options with. Source: I've worked 2 years on a warrant desk, as a desk developer." If you sold bought a call option then as you stated sold it to someone else what you are doing is selling the call you bought. That leaves you with no position.  This is the case if you are talking about the same strike, same expiration. Well sure but derivatives valuations that you see on this chart are complete bs. Normally the derivative (future or a swap) is actually worth zero. What this chart is tallying up is the notional which is an arbitrary number only used to calculate the P&amp;L on the derivative. Sorry but this is not really the value of the derivative, so hard to see how derivatives on this chart make any sense at all. "This doesn't make sense to me. Writing a covered call gives him a long delta position - the exact opposite of what he wants. And the tax losses won't turn a losing position into a winning one.  Is there something I'm missing?  Edit: Also, doesn't ""shorting against the box"" mean he has to have a long position, and short against that? That means you've got zero net delta, which isn't very useful at all..." "This is analyst speak for ""the stock isn't going anywhere anytime soon"". Remember these guys are offering advice to the entire universe in a few lines, so the advice gets fortune cookie-like. When I look at these things, I care more about when the analyst changes their opinion more than what the opinion is. If you really trust this person, you should listen to the earnings call for the stock (or read the transcript) and listen for the questions asked by the analyst. Usually you'll be able to understand why the analyst feels the way he does." "fennec has a very good answer but i feel it provides too much information. So i'll just try to explain what that sentence says. Put option is the right to sell a stock. ""16 puts on Cisco at 71 cents"", means John comes to Jim and says, i'll give you 71 cent now, if you allow me to sell one share of Cisco to you at $16 at some point in the future ( on expiration date).  NYT quote says 1000 puts that means 1000 contracts - he bought a right to sell 100,000 shares of Cisco on some day at $16/share. Call option - same idea: right to buy a stock." "An option is an instrument that gives you the ""right"" (but not the obligation) to do something (if you are long). An American option gives you more ""rights"" (to exercise on more days) than a European option. The more ""rights,"" the greater the (theoretical) value of the option, all other things being equal, of course. That's just how options work.  You could point to an ex post result, and and say that's not the case. But it is true ex ante." "According to Yahoo, AAPL was trading at $113.26 at 1:10 PM on 11/13/15, which is the approximate time of your option quote.  You provided a quote for AAPL at 4:15, and the stock happened to keep going down most of the that afternoon.  To make a sensible comparison, you need to take contemporary prices on both the stock and the option.  The quote on the option also shows the ""price"" being outside of the bid-ask range, which suggests that the option was trading thinly and that the last price occurred sometime earlier in the day.  If you use a price in the bid-ask range ($21.90-$22.30) and use the price of AAPL at the time of the put quote, you'll come up with a price that's much closer to your expectation." Options reflect expectations about the underlying asset, and options are commonly priced using the Black-Scholes model:  N(d1) and N(d2) are probability functions, S is the spot (current) price of the asset, K is the strike price, r is the risk free rate, and T-t represents time to maturity.  Without getting into the mathematics, it suffices to say that higher volatility or expectation of volatility increases the perceived riskiness of the asset, so call options are priced lower  and put options are priced higher. Think about it intuitively. If the stock is more likely to go downwards, then there's an increased chance that the call option expires worthless, so call options must be priced lower to accommodate the relative change in expected value of the option.  Puts are priced similarly, but they move inversely with respect to call option prices due to Put-Call parity. So if call option prices are falling, then put option prices are rising (Note, however, that call prices falling does not cause put prices to rise. The inverse relationship exists because of changes in the underlying factors and how pricing works.) So the option action signifies that the market believes the stock is headed lower (in the given time frame). That does not mean it will go lower, and option traders assume risk whenever they take a particular position. Bottom line: gotta do your own homework! Best of luck. "Alrighty.  So your question is, how confident are people that FB stock will close above a certain price at a certain time.  A ""call"" option contract allows you to buy shares in the future at a certain price.  FB calls are available for March of 2013.  The number in the ""strike"" column is the price you can buy FB stock at on the given date. Let's take the ""33.00"" strike.  This allows you to buy FB shares at $33 each next March.  If at that time it turns out they're worth $50 each, you can buy them at $33, then immediately sell them on the open market for $50, making money.  The person selling you the option knows that there's a chance the price will be above $33 in March, so he's going to charge you a few bucks to cover that possibility.  In this case, he's charging you $5.30 (as of me writing this).  So, you can have the option to buy FB shares at $33 each for $5.30.  This means the guy selling you the option is reasonably confident that in March, FB stock will be at or under $38.50, otherwise he'd lose money when you exercised the option.    Therefore, $38.50 is the option market's best guess as to the highest FB stock will be going for in March." "Is there ever any ambiguity on what that that exact strike is in delta space, or does everyone back it out from the pricing model the same way?  I ask, because in my product nearly everyone runs a heavier delta to the put (the severity of that varies). So on trades that are ""tied up"", everyone participating on it can have slightly different deltas that they are modeling" "The change is generally known as the Options Symbology Initiative (or ""OSI"") and there is a highly comprehensive guide to what occurred here. The basic gist of what occurred was a shift FROM: A coded system in which a shorter (3   to 5 letter symbol) could be used, but   the symbols required a data source to   determine what they meant. MSQ AD   used to be a MSFT Jan 20 option, but   you had to look up MSQ in a table to   know that. TO: A system in which much longer symbols   are needed, but they contain all the   information required to identify a   unique option: DELL 4.000 C 5/16/2010   isn't easy to type, but once you know   how to read it, it's easy to see that   it's an option on DELL, expiring on May 16th 2010, is a call (rather   than a put,) and has a strike price   of 4. As to why they did it, there are a number of benefits, but most important reason is this one:  they were running out of symbols.  The number of permutations of 3-5 letter symbols had been exceeded by the number of options that had been listed, resulting in the need to ""recycle"" symbols.   This meant that a current option symbol would be the same as an old one, in some cases on a different stock, which was wreaking havoc on historical data." "EDIT quid keenly identified the 1:7 reverse split In May 2017.  In a 1:7 reverse split, your shares are worth 7 times as much per share but you have 1/7 the amount of shares.  A share worth $3.78 now was worth (all else being equal) $0.54 a month ago.   So a call with a $2.50 strike a month ago was well out-of-the-money, and would now be the equivalent of a call with a $17.50 strike.  A $17.50 call with a $3.78 underlying (or a $2.50 call with a $0.54 underlying) would reasonably be worth only 5 cents. So I now suspect that the quote is a stale quote that existed pre-split and hasn't been adjusted by the provider. OLD ANSWER I can find no valid reason why those calls would be so cheap.  The stock price has been trending down from its onset in 2000, so either no one expects it to be above $2.50 in a month or it's so illiquid that there's not any real data to evaluate the options.  They did pay some massive (30%) dividends in 2010 and 2012, they've been hemorrhaging cash for the past 4 years at least, and I have found at least on ""strong sell"" rating, so there's not much to be optimistic about.  NASDAQ does not list any options for the stock, so it must be an OTC trade.   With an ask size of 10 you could buy calls on 1,000 shares for $0.05, so if you can afford to lose $50 and want to take a flyer you can give it a shot, but I suspect it's not a valid quote and is something that's been manufactured by the option broker."
