Put on a put option
I doubt that this exists, but it could theoretically. After all, a share is kind of an option to a company's future success, and so a call is already a second level on indirection. The better approach would be to 'create your own Put-Puts', by investing less money (A) in the Put you wanted to invest into, and put the smaller rest (B) in the share itself or a Call. That way, if the original Put is successful, at max (B) is lost, and if it is unsuccessful, the loss on (A) is covered by a gain on (B). Potentially, if you do the math, you can reach a mathematical equivalent situation to a Put-Put by buying the right amount and kind of Calls. However, we know already that buying a Put and a Call is a poor strategy, so that would mean a Put-Put would also be a poor strategy. If you look at it from the hedging perspective, if you're unsure you're going to need to hedge but want to lock in an option premium price if you do need to do so, I could see this making sense.
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. 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). &gt; The only problem I see with stock options is that they expire  You're on to something: the reason why some prefer to write (sell) options instead of buying. Neutral to bullish on crude oil? Sell puts on /CL at 90-95% probability OTM. You keep your money if the underlying moves up or does nothing, within the days to expiration. "The question you are asking concerns the exercise of a short option position.  The other replies do not appear to address this situation. Suppose that Apple is trading at $96 and you sell a put option with a strike price of $95 for some future delivery date - say August 2016.  The option contract is for 100 shares and you sell the contract for a premium of $3.20. When you sell the option your account will be credited with the premium and debited with the broker commission.  The premium you receive will be $320 = 100 x $3.20.  The commission you pay will depend on you broker. Now suppose that the price of Apple drops to $90 and your option is exercised, either on expiry or prior to expiry.  Then you would be obliged to take delivery of 100 Apple shares at the contracted option strike price of $95 costing you $9,500 plus broker commission.  If you immediately sell the Apple shares you have purchased under your contract obligations, then assuming you sell the shares at the current market price of $90 you would realise a loss of $500 ( = 100x($95-$90) )plus commission.  Since you received a premium of $320 when you sold the put option, your net loss would be $500-$320 = $180 plus any commissions paid to your broker. Now let's look at the case of selling a call option.  Again assume that the price of Apple is $96 and you sell a call option for 100 shares with a strike price of $97 for a premium of $3.60.  The premium you receive would be $360 = 100 x $3.60.  You would also be debited for commission by your broker. Now suppose that the price of Apple shares rises to $101 and your option is exercised.  Then you would be obliged to deliver 100 Apple shares to the party exercising the option at the contracted strike price of $97.  If you did not own the shares to effect delivery, then you would need to purchase those shares in the market at the current market price of $101, and then sell them to the party exercising the option at the strike price of $97.  This would realise an immediate loss of $400 = 100 x ($101-$97) plus any  commission payable.  If you did own the shares, then you would simply deliver them and possibly pay some commission or a delivery fee to your broker.  Since you received $360 when you sold the option, your net loss would be $40 = $400-$360 plus any commission and fees payable to the broker. It is important to understand that in addition to these accounting items, short option positions carry with them a ""margin"" requirement.  You will need to maintain a margin deposit to show ""good faith"" so long as the short option position is open.  If the option you have sold moves against you, then you will be called upon to put up extra margin to cover any potential losses." 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. "Cart's answer describes well one aspects of puts: protective puts; which means using puts as insurance against a decline in the price of shares that you own.  That's a popular use of puts.  But I think the wording of your question is angling for another strategy: Writing puts. Consider: Cart's strategy refers to the buyer of a put.  But, on the transaction's other side is a seller of the put – and ultimately somebody created or wrote that put contract in the first place!  That first seller of the put – that is, the seller that isn't just selling one they themselves bought – is the put writer. When you write a put, you are taking on the obligation to buy the other side's stock at the put exercise price if the stock price falls below that exercise price by the expiry date.  For taking on the obligation, you receive a premium, like how an insurance company charges a premium to insure against a loss. Example:  Imagine ABC Co. stock is trading at $25.00.  You write a put contract agreeing to buy 100 shares of ABC at $20.00 per share (the exercise price) by a given expiration date.  Say you receive $2.00/share premium from the put buyer.  You now have the obligation to purchase the shares from the put buyer in the event they are below $20.00 per share when the option expires – or, technically any time before then, if the buyer chooses to exercise the option early. Assuming no early assignment, one of two things will happen at the option expiration date: ABC trades at or above $20.00 per share. In this case, the put option will expire worthless in the hands of the put buyer.  You will have pocketed the $200 and be absolved from your obligation.  This case, where ABC trades above the exercise price, is the maximum profit potential. ABC trades below $20.00 per share.  In this case, the put option will be assigned and you'll need to fork over $2000 to the put buyer in exchange for his 100 ABC shares.  If those shares are worth less than $18.00 in the market, then you've suffered a loss to the extent they are below that price (times 100), because remember – you pocketed $200 premium in the first place.  If the shares are between $18.00 to $20.00, you're still profitable, but not to the full extent of the premium received. You can see that by having written a put it's possible to acquire ABC stock at a price lower than the market price – because you received some premium in the process of writing your put.  If you don't ""succeed"" in acquiring shares on your first write (because the shares didn't get below the exercise price), you can continue to write puts and collect premium until you do get assigned. I have read the book ""Money for Nothing (And Your Stocks for FREE!)"" by Canadian author Derek Foster.  Despite the flashy title, the book essentially describes Derek's strategy for writing puts against dividend-paying value stocks he would love to own.  Derek picks quality companies that pay a dividend, and uses put writing to get in at lower-than-market prices.  Four Pillars reviewed the book and interviewed Derek Foster: Money for Nothing: Book Review and Interview with Derek Foster. Writing puts entails risk.  If the stock price drops to zero then you'll end up paying the put exercise price to acquire worthless shares!  So your down-side can easily be multiples of the premium collected.  Don't do this until and unless you understand exactly how this works.  It's advanced. Note also that your broker isn't likely to permit you to write puts without having sufficient cash or margin in your account to cover the case where you are forced to buy the stock.  You're better off having cash to secure your put buys, otherwise you may be forced into leverage (borrowing) when assigned.  Additional Resources: The Montreal Exchange options guide (PDF) that Cart already linked to is an excellent free resource for learning about options.  Refer to page 39, ""Writing secured put options"", for the strategy above. Other major options exchanges and organizations also provide high-quality free learning material:" This is a snapshot of the Jan '17 puts for XBI, the biotech index.  The current price is $65.73. You can see that even the puts far out of the money are costly. The $40 put, if you get a fill at $3, means a 10X return if the index drops to $10. A 70X return for a mild, cyclic, drop isn't likely to happen.  Sharing youtube links is an awful way to ask a question. The first was far too long to waste my time. The second was a reasonable 5 minutes, but with no example, only vague references to using puts to protect you in bad years.  Proper asset allocation is more appropriate for the typical investor than any intricate option-based hedging strategy. I've successfully used option strategies on the up side, multiplying the returns on rising stocks, but have never been comfortable creating a series of puts to hit the jackpot in an awful year. "You're forgetting the fundamental issue, that you never have to actually exercise the options you buy.  You can either sell them to someone else or, if they're out of the money, let them expire and take the loss. It isn't uncommon at all for people to buy both a put and call option (this is a ""straddle"" when the strike price of both the put and call are the same). From Investopedia.com: A straddle is an options strategy in which the investor holds a position in both a call and put with the same strike price and expiration date, paying both premiums. This strategy allows the investor to make a profit regardless of whether the price of the security goes up or down, assuming the stock price changes somewhat significantly.   Read more: Straddle http://www.investopedia.com/terms/s/straddle.asp#ixzz4ZYytV0pT" 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. Options, both puts and calls, are typically written/sold at different strike prices. For example, even though the stock of XYZ is currently trading at $12.50, there could be put options for prices ranging from $0.50 to $30.00, just as an example. There are several factors that go into determining the strike prices at which people are willing to write options. The writer/seller of an option is the person on the other side of the trade that has the opposite opinion of you. If you are interested in purchasing a put on a stock to hedge your downside, that means the writer/seller of the put is betting that you are wrong and that the stock price will rise instead. Someone already mentioned that this is a risk-reversal, but as an aside, in the vol market (delta-hedged options) this is a fundamental skew trade. (buying calls, selling puts or vice versa). Initially vega neutral, the greek that this trade largely isolates is vanna (dvega/dspot or ddelta/dvol). "No.  The more legs you add onto your trade, the more commissions you will pay entering and exiting the trade and the more opportunity for slippage.  So lets head the other direction.   Can we make a simple, risk-free option trade, with as few legs as possible? The (not really) surprising answer is ""yes"", but there is no free lunch, as you will see.  According to financial theory any riskless position will earn the risk free rate, which right now is almost nothing, nada, 0%.   Let's test this out with a little example. In theory, a riskless position can be constructed from buying a stock, selling a call option, and buying a put option.  This combination should earn the risk free rate. Selling the call option means you get money now but agree to let someone else have the stock at an agreed contract price if the price goes up.  Buying the put option means you pay money now but can sell the stock to someone at a pre-agreed contract price if you want to do so, which would only be when the price declines below the contract price.  To start our risk free trade, buy Google stock, GOOG, at the Oct 3 Close:   495.52 x 100sh = $49,552 The example has 100 shares for compatibility with the options contracts which require 100 share blocks. we will sell a call and buy a put @ contract price of $500 for Jan 19,2013.   Therefore we will receive $50,000 for certain on Jan 19,2013, unless the options clearing system fails, because of say, global financial collapse, or war with Aztec spacecraft. According to google finance, if we had sold a call today at the close we would receive the bid, which is 89.00/share, or $8,900 total.  And if we had bought a put today at the close we would pay the ask, which is 91.90/share, or $9190 total. So, to receive $50,000 for certain on Jan 19,2013 we could pay $49,552 for the GOOG stock, minus $8,900 for the money we received selling the call option, plus a payment of $9190 for the put option we need to protect the value.  The total is $49,842.   If we pay $49,842 today, plus execute the option strategy shown, we would have $50,000 on Jan 19,2013.  This is a profit of $158, the options commissions are going to be around $20-$30, so in total the profit is around $120 after commissions.   On the other hand, ~$50,000 in a bank CD for 12 months at 1.1% will yield $550 in similarly risk-free interest.   Given that it is difficult to actually make these trades simultaneously, in practice, with the prices jumping all around, I would say if you really want a low risk option trade then a bank CD looks like the safer bet.  This isn't to say you can't find another combination of stock and contract price that does better than a bank CD -- but I doubt it will ever be better by very much and still difficult to monitor and align the trades in practice." "Options have legitimate uses as a way of hedging a bet, but in the hands of anyone but an expert they're gambling, not investing. They are EXTREMELY volatile compared to normal stocks, and are one of the best ways to lose your shirt in the stock market yet invented. How options actually work is that you're negotiating a promise that, at some future date or range of dates, they will let you purchase some specific number of shares (call), or they will let you sell them that number of shares (put), at a price specified in the option contract. The price you pay (or are paid) to obtain that contract depends on what the option's seller thinks the stock is likely to be worth when it reaches that date. (Note that if you don't already own the shares needed to back up a put option, you're promising to pay whatever it takes to buy those shares so you can sell them at the agreed upon price.) Note that by definition you're betting directly against experts, as opposed to a normal investment where you're usually trying to ride along with the experts. You are claiming that you can predict the future value of the stock better than they can, and that you will make a profit (on the difference between the value locked in by the option and the actual value at that time) which exceeds the cost of purchasing the option in the first place.  Let me say that again: the option's price will have been set based on an expert's opinion of what the stock is likely to do in that time. If they think that it's really likely to be up $10 per share when the option comes due (really unlikely for a $20 stock!!!), they will try to charge you almost $10 per share to purchase the option at the current price. ""Almost"" because you're giving them a guaranteed profit now and assuming all the risk. If they're less sure it will go up that much, you'll pay less for the option -- but again, you're giving them hard money now and betting that you can predict the probabilities better than they can. Unless you have information that the experts don't have -- in which case you're probably committing insider trading -- this is a very hard bet to win. And it can be extremely misleading, since the price during the option period may cross back and forth over the ""enough that you'll make a profit"" line many times. Until you actually commit to exercising the option or not, that's all imaginary money which may vanish the next minute. Unless you are willing and able to invest pro-level resources in this, you'd probably get better odds in Atlantic City, and definitely get better odds in Las Vegas. If you don't see the sucker at the poker table, he's sitting in your seat. And betting against the guy who designed and is running the game is usually Not a Good Idea." "As I stated in my comment, options are futures, but with the twist that you're allowed to say no to the agreed-on transaction; if the market offers you a better deal on whatever you had contracted to buy or sell, you have the option of simply letting it expire. Options therefore are the insurance policy of the free market. You negotiate a future price (actually you usually take what you can get if you're an individual investor; the institutional fund managers get to negotiate because they're moving billions around every day), then you pay the other guy up front for the right of refusal later. How much you pay depends on how likely the person giving you this option is to have to make good on it; if your position looks like a sure thing, an option's going to be very expensive (and if it's such a sure thing, you should just make your move on the spot market; it's thus useful to track futures prices to see where the various big players are predicting that your portfolio will move). A put option, which is an option for you to sell something at a future price, is a hedge against loss of value of your portfolio. You can take one out on any single item in your portfolio, or against a portion or even your entire portfolio. If the stock loses value such that the contract price is better than the market price as of the delivery date of the contract, you execute the option; otherwise, you let it expire. A call option, which is an option to buy something at a future price, is a hedge against rising costs. The rough analog is a ""pre-order"" in retail (but more like a ""holding fee""). They're unusual in portfolio management but can be useful when moving money around in more complex ways. Basically, if you need to guarantee that you will not pay more than a certain per-share price to buy something in the future, you buy a call option. If the spot price as of the delivery date is less than the contract price, you buy from the market and ignore the contract, while if prices have soared, you exercise it and get the lower contract price. Stock options, offered as benefits in many companies, are a specific form of call option with very generous terms for whomever holds them. A swaption, basically a put and a call rolled into one, allows you to trade something for something else. Call it the free market's ""exchange policy"". For a price, if a security you currently hold loses value, you can exchange it for something else that you predicted would become more valuable at the same time. One example might be airline stocks and crude oil; when crude spikes, airline stocks generally suffer, and you can take advantage of this, if it happens, with a swaption to sell your airline stocks for crude oil certificates. There are many such closely-related inverse positions in the market, such as between various currencies, between stocks and commodities (gold is inversely related to pretty much everything else), and even straight-up cash-for-bad-debt arrangements (credit-default swaps, which we heard so much about in 2008)." "Long here does not mean you wish for the underlying stock to increase in value, in fact, as the chart shows, just the opposite is true.  ""Long means you bought the derivative, and you own the option. The guy that sold it to you is at your mercy, he is short the put, and it's your decision to put the stock to him should it fall in value.  The value of the put itself rises with the falling stock price, you are long the put and want the put, itself, to rise in value."
