If I have all this stock just sitting there, how can I lend it out to people for short selling?
"One alternative strategy you may want to consider is writing covered calls on the stock you have ""just sitting there"".  This will allow you to earn a return (the premium from the calls) without necessarily having to give up your holding. As a brief overview, ""options"" are derivatives that give the holder the right (or option) to buy or sell shares at a specified price.  Holders of call options with a strike prike $x on a particular security have the right to purchase that security at the strike price $x.  Conversely, holders of put options with a strike price of $x have the right to sell that security at the strike price $x.  Always on the other side of a call or put option is a person that has sold the option, which is called ""writing"" the option.  If this person writes a call option, then he will be obligated to sell a certain amount of stock (100 shares per contract) at the strike price if that option is exercised.  A writer of a put option will be obligated to by 100 shares per contract at the strike price if that option is exercised. Covered calls involve writing call contracts on stock that you own.  For example, say you own 100 shares of AAPL, and that AAPL is currently trading for $330.  You decide to write a Jan 21, 2012 call on these shares at a strike price of $340, earning you a premium of say $300. Two things can now happen: if the price of AAPL is not at least $340 on January 21, then the options are ""out of the money"" and will expire unexercised (why exercise an option to buy at $340 when you can buy at the currently cheaper market price?).  You keep your AAPL stock plus the $300 premium you earn.  If, however, the price of AAPL is greater than $340, the option will be exercised and you will now be required to sell the shares you own at $340.  You will earn a return of $10/share ($340-$330), plus the $300 premium from the call option.  You still make out in the end, but have unfortunately incurred an opportunity cost, as had you not written the call option you would have been able to sell at the market price, which is higher than the $340 strike price. Covered calls are considered relatively safe and conservative, however the strategy is most effective for stocks that are expected to stay within a relatively narrow price range for the duration of the contract.  They do provide one option of earning additional money on stocks you are currently holding, albeit at the risk of giving up some returns if the stock price rises above the strike price." Typically, as an individual, you can't just decide you want to lend out some securities. There is a lot of legalities that must take place in order to engage in such a transaction. It's a regulated industry and the contractual obligations that exist between borrower and seller are taken care of ahead of time by the broker with their client, prior to any actual transaction taking place. http://en.wikipedia.org/wiki/Securities_lending I say typically, becuase I'm guessing that if you are a large enough client and own a substantial block of shares (I really mean a lot) you may be in the unique position of being able to lend out. I'm not sure what the logistics of this would look like, but I think the brokerage house would approach you and negotiate a borrowing rate. In that situation, you may negotiate lending to the the brokerage house and not necessarily directly to the borrower. You just disclosed that you are new investor to the stock market. I'd advise that you first understand investing a bit better, as most will advise that investors need to be above a certain level before picking individual stocks.  That said, most stocks trade in high enough volume and have low enough short interest that they don't fall under the category you seek. You want to first ask your broker if they have such a process, not all do. If so, they would need to provide you with the stocks that fall into this odd situation, specifically, the shares that have traders seeking to short the stock, but the stock is unavailable. Even then, the broker may have requirements that you don't fall into, minimum history with broker, minimum size account, etc. Worse, they are not likely to offer this for 100 shares, but may have a 1000 or higher share requirement. Are you willing to buy some obscure $50/sh priced stock to lend out at 1%/mo? The guy trying to short it is far smarter than both you and I, at least regarding this particular stock. This strategy is more appropriate for the 7 figure net worth investor.  If any reader has actual experience with this, I'm happy to hear it. This response is from my recollection of two articles I read about 3 years ago, coincidence they both were published within weeks of each other. Lending of securities is done by institutional investors and mutual funds. The costs of dealing with thousands of individual investors, small share blocks and the various screw-ups and drama associated with each individual are too high. Like many exotic financial transactions, if you have to ask about it, you're probably not qualified to do it.
"Concerning the general problem of short selling and the need to borrow shares to complete the transaction : Selling short is a cash transaction.  Unlike a futures contract, where a short seller is entering into a legal agreement to sell something in the future, in the case of short selling a share the buyer of the share is taking immediate delivery and is therefore entitled to all of the benefits and rights that come with share ownership.  In particular, the buyer of the shares is entitled to any dividends payable and, where applicable, to vote on motions at AGMs.  If the short seller has not borrowed the shares to sell, then buyer of non-existent shares will have none of the rights associated with ownership. The cash market is based on the idea of matching buyers and sellers.  It does not accommodate people making promises. Consider that to allow short sellers to sell shares they have not borrowed opens up the possibility of the aggregate market selling more shares than actually exist.  This would lead to all sorts of problematic consequences such as heavily distorting the price of the underlying share.  If everyone is selling shares they have not borrowed willy-nilly, then it will drive the price of the share down, much to the disadvantage of existing share holders. In this case, short sellers who have sold shares they have not already borrowed would be paying out more in dividends to the buyers than the total dividends being paid out by the underlying company. There are instruments that allow for short selling of unowned shares on a futures basis.  One example is a CFD = Contract for Difference.  In the case of CFDs, sellers are obliged to pay dividends to buyers as well as other  costs related to financing. EDIT Regarding your comment, note that borrowing shares is not a market transaction.  Your account does not show you buying a share and then selling it.  It simply shows you selling a share short.  The borrowing is the result of an agreement between yourself and the lender and this agreement is off market.  You do not actually pay the lender for the shares, but you do pay financing costs for the borrowing so long as you maintain your short position. EDIT I realise that I have not actually read your question correctly.  You are not actually talking about ""naked"" short selling.  You are talking about selling shares you already own in a hope of maintaining both a long and short position (gross).  The problem with this approach is that you must deliver the shares to the buyer.  Otherwise, ask yourself what shares is the buyer actually buying if you want the bought shares to remain in your account. If you are not going to deliver your long position shares, then you will need to borrow the shares you are selling short for the reasons I have outlined above." Shorting Stocks: Borrowing the shares to sell now. Then buying them back when the price drops.  Risk: If you are wrong the stock can go up. And if there are a lot of people shorting the stock you can get stuck in a short squeeze.  That means that so many people need to buy the stock to return the ones they borrowed that the price goes up even further and faster.  Also whoever you borrowed the stock from will often make the decision to sell for you. Put options. Risk: Put values don't always drop when the underlying price of the stock drops. This is because when the stock drops volatility goes up. And volatility can raise the value of an option. And you need to check each stock for whether or not these options are available. finviz lists whether a stock is optional & shortable or not. And for shorting you also need to find a broker that owns shares that they are willing to lend out. "Diversify into leveraged short/bear ETFs and then you can quit your job and yell at your boss ""F you I'm short your house!"" edit: this is a quote from Greg Lippmann and mentioned in the book ""The Big Short""" "Learn something new every day... I found this interesting and thought I'd throw my 2c in. Good description (I hope) from Short Selling: What is Short Selling First, let's describe what short selling means when you purchase shares of stock. In purchasing stocks, you buy a piece of ownership in the company. You buy/sell stock to gain/sell ownership of a company. When an investor goes long on an investment, it means that he or she has bought a stock believing its price will rise in the future. Conversely, when an investor goes short, he or she is anticipating a decrease in share price. Short selling is the selling of a stock that the seller doesn't own. More specifically, a short sale is the sale of a security that isn't owned by the seller, but that is promised to be delivered.  Still with us? Here's the skinny: when you short sell a stock, your broker will lend it to you. The stock will come from the brokerage's own inventory, from another one of the firm's customers, or from another brokerage firm. The shares are sold and the proceeds are credited to your account. Sooner or later, you must ""close"" the short by buying back the same number of shares (called covering) and returning them to your broker. If the price drops, you can buy back the stock at the lower price and make a profit on the difference. If the price of the stock rises, you have to buy it back at the higher price, and you lose money. So what happened? The Plan The Reality Lesson I never understood what ""Shorting a stock"" meant until today. Seems a bit risky for my blood, but I would assume this is an extreme example of what can go wrong. This guy literally chose the wrong time to short a stock that was, in all visible aspects, on the decline.  How often does a Large Company or Individual buy stock on the decline... and send that stock soaring? How often does a stock go up 100% in 24 hours? 600%?  Another example is recently when Oprah bought 10% of Weight Watchers and caused the stock to soar %105 in 24 hours. You would have rued the day you shorted that stock - on that particular day - if you believed enough to ""gamble"" on it going down in price." It's actually quite simple. You're actually confusing two concept. Which are taking a short position and short selling itself. Basically when taking a short position is by believing that the stock is going to drop and you sell it. You can or not buy it back later depending on the believe it grows again or not. So basically you didn't make any profit with the drop in the price's value but you didn't lose money either.  Ok but what if you believe the market or specific company is going to drop and you want to profit on it while it's dropping. You can't do this by buying stock because you would be going long right? So back to the basics. To obtain any type of profit I need to buy low and sell high, right? This is natural for use in long positions. Well, now knowing that you can sell high at the current moment and buy low in the future what do you do? You can't sell what you don't have. So acquire it. Ask someone to lend it to you for some time and sell it. So selling high, check.  Now buying low? You promised the person you would return him his stock, as it's intangible he won't even notice it's a different unit, so you buy low and return the lender his stock. Thus you bought low and sold high, meaning having a profit. So technically short selling is a type of short position. If you have multiple portfolios and lend yourself (i.e. maintaining a long-term long position while making some money with a short term short-term strategy) you're actually short selling with your own stock. This happens often in hedge funds where multiple strategies are used and to optimise the transaction costs and borrowing fees, they have algorithms that clear (match) long and short coming in from different traders, algorithms, etc. Keep in mind that you while have a opportunities risk associated.  So basically, yes, you need to always 'borrow' a product to be able to short sell it. What can happen is that you lend yourself but this only makes sense if: "You can't short a stock unless there is someone willing and able to ""lend"" shares to you. And there are several reasons why that might not be the case. First, BSFT is a ""new"" stock, which means that NO ONE has held it very long. It's much easier to short IBM or Exxon Mobil, where there are some long-term holders who would like to earn a little extra money lending you THEIR shares. But if ""everyone"" involved is busy buying or selling the stock, there won't be many people to lend it. That's not manipulation, that's just the market. Another reason may be a large ""short"" interest. That is many OTHERS have shorted it before you. That's dangerous for you, because if some lenders want to pull their shares off the market, they can cause a ""short squeeze"" that will drive the price much higher.  And stock shortages can be orchestrated by the company or large investors to artificially drive the price higher. Unless you have a lot of experience, don't try shorting small cap stocks. Try to gain some experience with large caps like IBM or Exxon Mobil first. Those are stocks that people at least can't ""play games"" with. YOu will win or lose based on the market itself." Any publicly traded financial instrument can be sold short, in theory.  There are, however, many regulations associated with short sales of US equities that may prevent certain stocks from being sold short at certain times or through certain brokers. Some examples: the most basic requirement (this isn't a regulation, it's just the definition of a short sale) is that you or your broker must have access to someone willing to loan you his/her shares.  If you are interested in shorting a security with few shares outstanding or low trade volume, there may simply not be enough people in the world willing to loan you theirs.  Alternatively, there may be a shareholder willing to loan shares, but your broker may not have a relationship with the clearing house that shareholder is using.  A larger/better/different broker might be able to help. threshold securities list - since 2005, each day certain securities are not allowed to be sold short based on their recent history of liquidity.  Basically, if a certain number of transactions in a security have not been correctly settled over the past few days, then the SEC has reason to believe that short sales (which require extra transactions) are at higher risk of falling through. circuit breaker a.k.a. alternative uptick - since 2011, during certain market conditions, exchanges are now required to reject short sales for certain securities in order to prevent market crashes/market abuse. Brokers have the right to charge interest on any stock that they lend you. Since you borrowed the TSLA to short it, the owner of those shares can charge you interest until you return them. If you are not getting charged interest on some shares that you have borrowed to short, consider it generosity on the part of the lender. ELI5 - you sell something that you don't own with the expectation that it will go down, and then you buy it back when it goes down in order to lock in profit.  You are charged fees to borrow the stock from someone else who currently owns it, and you also run the risk of the market going against you by going up. In terms of pricing the asset, this functions in exactly the same way as a regular sell, so bids will have to be hit to fill the trade. When shorting an equity, currency is not borrowed; the equity is, so the value of per share liability is equal to it's last traded price or the ask if the equity is illiquid. Thus when opening a short position, the asks offer nothing to the process except competition for your order getting filled. Part of managing the trade is the interest rate risk.  If the asks are as illiquid as detailed in the question, it may be difficult even to locate the shares for borrowing. As a general rule, only illiquid  equities or those in free fall may be temporarily unable for shorting. Interactive Brokers posts their securities financing availabilities and could be used as a proxy guide for your broker. But by closing the short position the broker would still be purchasing shares from the market no? Or at least, someone would be purchasing the shares to close the short position. So, why doesn't the broker just let Client A keep their short position open and buy shares in the market so that Client B can sell them...I know it sounds a bit ridic, but not much more so to me than letting Client A borrow the shares to begin with! "Basically, you either borrow money, or get other people to invest in your business by buying stock or something analogous.  Sometimes you can get people to ""park"" money with you. For example, many people deposit money in a bank checking account. They don't get any interest or other profit from this, they just do it because the bank is a convenient place to store their money. The bank then loans some percentage of this money out and keeps the interest. I don't doubt that people have come up with more clever ways to use other people's money. Borrowing money for an investment or business venture is risky because if you lose money, you may be unable to pay it back. On the other hand, investors expect a share of the profit, not just a fixed interest rate." "Lending of shares happens in the background. Those who have lent them out are not aware that they have been lent out, nor when they are returned. The borrowers have to pay any dividends to the lenders and in the end the borrowers get their stock back. If you read the fine print on the account agreement for a margin account, you will see that you have given the brokerage the permission to silently loan your stocks out.  Since the lending has no financial impact on your portfolio, there's no particular reason to know and no particular protection required.  Actually, brokers typically don't bother going through the work of finding an actual stock to borrow.  As long as lots of their customers have stocks to lend and not that many people have sold short, they just assume there is no problem and keep track of how many are long and short without designating which stocks are borrowed from whom. When a stock becomes hard to borrow because of liquidity issues or because many people are shorting it, the brokerage will actually start locating individual shares to borrow, which is a more time-consuming and costly procedure.  Usually this involves the short seller actually talking to the broker on the phone rather than just clicking ""sell.""" It would involve manual effort, but there is just a handful of exclusions,  buy the fund you want, plug into a tool like Morningstar Instant X Ray,  find out your $10k position includes $567.89 of defense contractor Lockheed Martin,  and sell short $567.89 of Lockheed Martin.  Check you're in sync periodically (the fund or index balance may change); when you sell the fund close your shorts too. "Every investment comes with a risk. There is also a bit of speculation involved. In there is an anticipation that one expects the value to go up in normal course of events. By your definition ""If I buy this equipment, I could produce more widgets, or sell more widgets,"" as an investment. Here again there is an anticipation that the widgets you sell will give you more return. If you are investing in stock/share, you are essentially holding a small portion of value in company and to that extent you are owining some equipment that is producing some widget .... Hence when you are purchasing Stocks, it would be looked as investment if you have done your home work and have a good plan of how you want to invest along with weiging the risk involved. However if you are investing only for the purpose of making quick bucks following so called hot tips, then you are not investing but speculating."
