What is the meaning of “writing put options”?
"Write means sell to open.  It is called that because options writers are creating (i.e. writing) new contracts. No such thing as ""reading"" an option." Apple closed Friday 9/23 at $403.40.   This is what the Puts look like, note the 2013 expiration.  (The rest is hypothetical, I am not advising this.) As a fan of Apple and feeling the stock may stay flat but won't tank, I sell you the $400 put for $64.65.  In effect I am saying that I am ready willing and able to buy aapl for $400 (well, $40,000 for 100 shares) and I have enough margin in my account to do so, $20,000. If Apple keeps going up, I made my $6465 (again it's 100 shares) but no more. If it drops below $400, I only begin to lose money if it goes below $335.35.  You, the put buyer are betting it will drop by this amount (more than 15% from today) and are willing to pay the price for this Put today. "Writing a put for a stock means you are selling the right to sell you stock. Simply put (er no pun intended), ""writing put options"" means you are selling somebody else the right (a contract) to sell YOU a specific stock at a specific price before a specific date.  I imagine the word ""write"" to refer to the physical act of creating a contract.   The specific price is called the STRIKE and the specific date is the EXPIRATION.  By ""writing a put"", you are agreeing to purchase the stock at a particular price (the STRIKE price) before the expiration.  You get paid a fee, the ""premium"", for agreeing to purchase the stock at the strike price if asked to.  If the holder of the contract decides to make you buy the stock at the strike price, you have to do it.     If the stock never dips below the strike price, then the holder of the put contract (a contract you wrote), will never exercise their right because they'd lose money.  But if the stock drops to zero, you could potentially lose up to your strike price (times the number of shares at stake), if the holder of the contract decides to exercise.   Therefore, ""writing puts"" is a LONG position, meaning you stand to gain if the stock goes up.  FYI - ""LONG"" refers direction (UP!), not duration." "Writing options means ""selling"" options and ""put"" options are contracts to sell a defined security (the underlying), at a specific date (expiration date) and at a specific price (strike price). So, writing put options simply mean selling to others contracts to sell. Your profit is limited to the premium but your loss may be unlimited in a falling market." Suppose you're writing a put with a strike price of 80. Say the share's(underlying asset) price goes down to 70. So the holder of the put will exercise the option. Ie he has a 'right to sell' a share worth 70 for rs 80. Whereas a put option writer has an 'obligation to buy' at rs 80 a share trading at rs 70. Always think from the perspective of the holder. If the holder exercises the option, the writer will suffer a loss. Maximum loss he suffers will be the break even FSP, which is Strike price reduced by the premium paid.. If he doesn't exercise the option the writer will make a profit, which can maximum be the put premium received.
"A derivative contract can be an option, and you can take a short (sell) position , much the same way you would in a stock. When BUYING options you risk only the money you put in. However when selling naked(you don't have the securities or cash to cover all potential losses) options, you are borrowing. Brokers force you to maintain a required amount of cash called, a maintenance requirement. When selling naked calls - theoretically you are able to lose an INFINITE amount of money, so in order to sell this type of options you have to maintain a certain level of cash in your account. If you fail to maintain this level you will enter into whats often referred to as a ""margin-call"". And yes they will call your phone and tell you :). Your broker has the right to liquidate your positions in order to meet requirements. PS: From experience my broker has never liquidated any of my holdings, but then again I've never been in a margin call for longer then a few days and never with a severe amount. The margin requirement for investors is regulated and brokers follow these regulations." There is such a thing as a buy-write, which is buying a stock and writing a (covered) call simultaneously. But as far as I know brokers charge two commissions, one stock trade and one options trade so you're not going to save on commissions. I think George's answer explains fairly well why the brokerages don't allow this - it's not an exchange rule, it's just that the brokerage has to have the shares to lend, and normally those shares come from people's margin, which is impossible on a non-marginable stock. To address the question of what the alternatives are, on popular stocks like SIRI, a deep In-The-Money put is a fairly accurate emulation of an actual short interest.  If you look at the options on SIRI you will see that a $3 (or higher) put has a delta of -$1, which is the same delta as an actual short share. You also don't have to worry about problems like margin calls when buying options.  The only thing you have to worry about is the expiration date, which isn't generally a major issue if you're buying in-the-money options... unless you're very wrong about the direction of the stock, in which case you could lose everything, but that's always a risk with penny stocks no matter how you trade them. At least with a put option, the maximum amount you can lose is whatever you spent on the contract.  With a short sale, a bull rush on the stock could potentially wipe out your entire margin.  That's why, when betting on downward motion in a microcap or penny stock, I actually prefer to use options.  Just be aware that option contracts can generally only move in increments of $0.05, and that your brokerage will probably impose a bid-ask spread of up to $0.10, so the share price has to move down at least 10 cents (or 10% on a roughly $1 stock like SIRI) for you to just break even; definitely don't attempt to use this as a day-trading tool and go for longer expirations if you can. "Q: A: Everyone that is short is paying interest to the owners of the shares that the short seller borrowed. Although this quells your conundrum, this is also unrelated to the term. Interest in this context is just the number. In the options market, each contract also has an open interest, which tells you how many of that contract is being held. For your sake, think of it as ""how many are interested"", but really its just a completely different context." The only problem with writing puts is that you need to buy the futures, and at the moment at least that is what I am trying to avoid (trying to be as frugal with my investing dollars). I will however consider that strategy, since it does make sense. "Great answer by @duffbeer. Only thing to add is that the option itself becomes a tradeable asset. Here's my go at filling out the answer from @duffbeer. ""Hey kid... So you have this brand-new video game Manic Mazes that you paid $50 for on Jan 1st that you want to sell two months from now"" ""Yes, Mr. Video Game Broker, but I want to lock in a price so I know how much to save for a new Tickle Me Elmo for my baby sister."" ""Ok, for $3, I'll sell you a 'Put' option so you can sell the game to me for $40 in two months."" Kid says ""Ok!"", sends $3 to Mr Game Broker who sends our kid a piece of paper saying: The holder of this piece of paper can sell the game Manic Mazes to Mr Game Broker for $40 on March 1st. .... One month later .... News comes out that Manic Mazes is full of bugs, and the price in the shops is heavily discounted to $30. Mr Options Trader realizes that our kid holds a contract written by Mr Game Broker which effectively allows our kid to sell the game at $10 over the price of the new game, so maybe about $15 over the price in the second-hand market (which he reckons might be about $25 on March 1st). He calls up our kid. ""Hey kid, you know that Put option that Mr Game Broker sold to you you a month ago, wanna sell it to me for $13?"" (He wants to get it a couple of bucks cheaper than his $15 fair valuation.) Kid thinks:  hmmm ... that would be a $10 net profit for me on that Put Option, but I wouldn't be able to sell the game for $40 next month, I'd likely only get something like $25 for it. So I would kind-of be getting $10 now rather than potentially getting $12 in a month. Note: The $12 is because there could be $15 from exercising the put option (selling for $40 a game worth only $25 in the second-hand market) minus the original cost of $3 for the Put option. Kid likes the idea and replies: ""Done!"". Next day kid sends the Put option contract to Mr Options Trader and receives $13 in return. Our kid bought the Put option and later sold it for a profit, and all of this happened before the option reached its expiry date." See how you can only make the premium amount but your risk is the same as holding the stock when writing a put option. The risk situation of the put option is the same whether you own the stock or not.  You risk $5 and stand to gain 0 to $250 in the period before expiration (say $50 if the stock reaches $200 and you sell).   Holding the stock or not changes nothing about that.  What is different is the consideration as to whether or not to buy a put when you own the stock.  Without an option, you are holding a $250 asset (the stock), and risking that money.  Should you sell and miss opportunity for say $300? Or hold and risk loss of say $50 of your $250?  So you have $250 at risk, but can lock in a sale price of $245 for say a month by buying a put, giving you opportunity for the $300 price in that month.  You're turning a risk of losing $250 (or maybe only $50 more realistically) into a risk of losing only $5 (versus the price your stock would get today). Oh it is ok. I was a little confused, because I tried to read up on future options and options as much as possible, and to still get question marks worried me. I mean to my knowledge, options can be traded as is without margin, while futures do need margin. If you are a starving artist, you can see the draw of not having to have margin to keep track of, but be able at the same time to learn about another market to trade in (commodities). "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.

"You are likely making an assumption that the ""Short call"" part of the article you refer to isn't making: that you own the underlying stock in the first place. Rather, selling short a call has two primary cases with considerably different risk profiles. When you short-sell (or ""write"") a call option on a stock, your position can either be: covered, which means you already own the underlying stock and will simply need to deliver it if you are assigned, or else uncovered (or naked), which means you do not own the underlying stock. Writing a covered call can be a relatively conservative trade, while writing a naked call (if your broker were to permit such) can be extremely risky. Consider: With an uncovered position, should you be assigned you will be required to buy the underlying at the prevailing price. This is a very real cost — certainly not an opportunity cost. Look a little further in the article you linked, to the Option strategies section, and you will see the covered call mentioned there. That's the kind of trade you describe in your example." Put options are basically this. Buying a put option gives you the right but not the obligation to sell the underlying security at a certain date for a fixed price, no matter its current market value at that time. However, markets are largely effective, and the price of put options is such that if you bought them to cover you the whole time, you would on average pay more than you'd gain from the underlying security. There is no such thing as a risk-free investment. The option is exercised. The option is converted into shares. That is an optional condition in closing that contract, hence why they are called options. "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." A specific strategy to make money on a potentially moderately decreasing stock price on a dividend paying stock is to write covered calls.  There is a category on Money.SE about covered call writing, but in summary, a covered call is a contract to sell the shares at a set price within a defined time range; you gain a premium (called the time value) which, when I've done it, can be up to an additional 1%-3% return on the position.  With this strategy you're collecting dividends and come out with the best return if the stock price stays in the middle: if the price does not shoot up high enough that your option is called, you still own the stock and made extra return; if the price drops moderately, you may still be positive.
