How do I hedge stock options like market makers do?
"How do option market makers actually hedge their positions so that they do not have a price risk? You cannot complete hedge away price risk of a sold call simply by buying the underlying and waiting.  As the price of the underlying decreases, the ""Delta"" (price risk) decreases, so as the underlying decreases, you would gradually sell some of the underlying to reduce your price risk from the underlying to match the price risk of the option. The opposite is true as well - as the price of the underlying increases, you'd buy more of the underlying to maintain a ""delta neutral"" position. If you want to employ this strategy, first you need to fully understand what ""delta"" is and how to calculate it.  Then you can use delta hedging to reduce your price risk." Buying the underlying asset will not completely hedge you, only what lies above 155 dollars (strike + price of option) - you still have the risk of losing everything but 5. You have a maximum earnings-potential of 55 dollars (strike of 150 - investment of 100 + option of 5) but you have a risk of losing 95$ (investment of 100 - option of 5). Say chance of winning everything or losing everything is 50-50, your expected outcome is 0.5 x -95 + 0.5 x 55 = -20$. Is this a great investment? Sure you don't know your odds - otherwise it would be a sure thing. You shouldn't sell the call option if you do not expect prices to go up - but in that case - why not just buy the underlying alone? Speculating in options is a dangerous game with infinite earnings-potential but also infinite loss potential. (Consider selling a call option and not buying the underlying and the price goes from 100 to 1.000.000.000). Let's consider that transaction cost is 0(zero) for calculation. In the scenario you have stated, maximum profit that could be made is 55$, however risk is unlimited. Hedging can also be used to limit your losses, let's consider this scenario. Stock ABC trading @ 100$, I'll buy the stock ABC @ 100$ and buy a put option of ABC @ strike price 90$ for a premium of 5$ with an expiration date of 1 month. Possible outcomes I end up in a loss in 3 out of 4 scenarios, however my loss is limited to 15$, whereas profit is unlimited.
"I think that pattern is impossible, since the attempt to apply the second half would seem to prevent executing the first. Could you rewrite that as ""After the stock rises to $X, start watching for a drop of $Y from peak price; if/when that happens, sell."" Or does that not do what you want? (I'm not going to comment on whether the proposed programmed trading makes sense. Trying to manage things at this level of detail has always struck me as glorified guesswork.)" Check out this site: http://www.m-x.ca/produits_options_actions_en.php  (Under the Trading Strategies). If you have a background in math or eco or are comfortable with graphs, I suggest you graph the payoffs of each of these strategies.  It will really help you understand it.  If you need help with this, let me know and I can draw a couple out for you. Your question is rather vague but also complicated however I will try to answer it.  First off, many investors buy options to hedge against a current position in a stock (already own the stock).  But you can also try to make money off of options rather than protecting yourself. Let's suppose you anticipate that a stock will increase in value so you want to capitalize on this.  Suppose further that you have a small amount of money to invest, say $100.  Suppose the stock is currently at $100 so that you can only afford 1 share.  Suppose there is a call option out there with strike $105 that costs you only $1. Let's compare two scenarios: The stock increases to $120 at the maturity date of the option. So, you made a lot more money with the same initial investment.  The amount of money you put in is small (i.e. can be perceived as low risk).  However, if the stock price ended up being $104.90 then your options are worthless (i.e. can be perceived as high risk). HTH. I understand what you're asking for (you want to write options ON call options... essentially the second derivative of the underlying security), and I've never heard of it. That's not to say it doesn't exist (I'm sure some investment banker has cooked something like this up at some point), but if it does exist, you wouldn't be able to trade it as easily as you can a put or a LEAP. I'm also not sure you'd actually want to buy such a thing - the amount of leverage would be enormous, and you'd need a massive amount of margin/collateral.  Additionally, a small downward movement in the stock price could wipe out the entire value of your option. 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. You're assuming options traded on the open market. To close open positions, a seller buys them back on the open market. If there's little on offer, this will drive the price up. "This is a complicated subject, because professional traders don't rely on brokers for stock quotes.  They have access to market data using Level II terminals, which show them all of the prices (buy and sell) for a given stock.   Every publicly traded stock (at least in the U.S.) relies on firms called ""market makers"".  Market makers are the ones who ultimately actually buy and sell the shares of companies, making their money on the difference between what they bought the stock at and what they can sell it for.  Sometimes those margins can be in hundreds of a cent per share, but if you trade enough shares...well, it adds up. The most widely traded stocks (Apple, Microsoft, BP, etc) may have hundreds of market makers who are willing to handle share trades.  Each market maker sets their own price on what they'll pay (the ""bid"") to buy someone's stock who wants to sell and what they'll sell (the ""ask"") that share for to someone who wants to buy it.   When a market maker wants to be competitive, he may price his bid/ask pretty aggressively, because automated trading systems are designed to seek out the best bid/ask prices for their trade executions.  As such, you might get a huge chunk of market makers in a popular stock to all set their prices almost identically to one another.  Other market makers who aren't as enthusiastic will set less competitive prices, so they don't get much (maybe no) business.  In any case, what you see when you pull up a stock quote is called the ""best bid/ask"" price.  In other words, you're seeing the highest price a market maker will pay to buy that stock, and the lowest price that a market maker will sell that stock.  You may get a best bid from one market maker and a best ask from a different one.  In any case, consumers must be given best bid/ask prices. Market makers actually control the prices of shares.  They can see what's out there in terms of what people want to buy or sell, and they modify their prices accordingly.  If they see a bunch of sell orders coming into the system, they'll start dropping prices, and if people are in a buying mood then they'll raise prices. Market makers can actually ignore requests for trades (whether buy or sell) if they choose to, and sometimes they do, which is why a limit order (a request to buy/sell a stock at a specific price, regardless of its current actual price) that someone places may go unfilled and die at the end of the trading session.  No market maker is willing to fill the order. Nowadays, these systems are largely automated, so they operate according to complex rules defined by their owners.  Very few trades actually involve human intervention, because people can't digest the information at a fast enough pace to keep up with automated platforms. So that's the basics of how share prices work.  I hope this answered your question without being too confusing! Good luck!" You sold a call, and have a risk if the stock rises.  You bought a put and gain when the stock drops. You, sir, have a synthetic short position.  It's Case 3 from your linked example: Suppose you own Long Stock and the company is going to report earnings   but you’re going on vacation. How can you hedge your position without   selling your stock? You can short the stock synthetically with   options! Short Stock = Short Call + Long Put They conclude with the net zero remark, because the premise was an existing long position. A long plus this synthetic short results in a neutral set of positions (and the author's ability to go on vacation not concerned about any movement in the stock.) You are probably right that using a traditional buy and hold strategy on common equities or funds is very unlikely to generate the types of returns that would make you a millionaire in short order. However, that doesn't mean it isn't possible. You just have to accept a more risk to become eligible for such incredible returns that you'd need to do that. And by more risk I mean a LOT more risk, which is more likely to put you in the poorhouse than a mansion. Mostly we are talking about highly speculative investments like commodities and real estate. However, if you are looking for potential to make (or more likely lose) huge amounts of money in the stock market without a very large cache of cash. Options give you much more leverage than just buying a stock outright. That is, by buying option contracts you can get a much larger return on a small movement in the stock price compared to what you would get for the same investment if you bought the stock directly.  Of course, you take on additional risk. A normal long position on a stock is very unlikely to cause you to lose your entire investment, whereas if the stock doesn't move far enough and in the right direction, you will lose your entire investment in option contracts. If you have your long positions established and are investing responsibly (assuming you know the risks and can accept them), the next step IMO is typically learning hedging - using options or option strategies to solidify positions. Collars (zero cost) and put options are a good place to start your education and they can be put to use to both speculate (what you are effectively doing with short-position trading) or long-term oriented edging. Day trading equites can be lucrative but it is a difficult game to play - learning options (while more complex on speculation) can provide opportunities to solidify positions. Options trading is difficult grounds. I just think the payoff long term to knowing options is much greater than day-trading tactics (because of versatility) I guess I wasn't clear. I want to modestly leverage (3-4x) my portfolio using options. I believe long deep-in-the-money calls would be the best way to do this? (Let me know if not.)  It's important to me that the covariance matrix from the equity portfolio scales up but doesn't fundamentally change. (I liken it to systemic change as opposed to idiosyncratic change.)   This is what I was thinking:  * For the same expiry date, find each positions lowest lambda. * Match all option to the the highest of the lowest lambda. * Adjust number of contracts to compensate for higher leverage.  I don't think this will work because if I matched the lowest lambda of options on bond etfs to my equity options they would be out-of-the-money.  By the way, thanks for your time. I used to be a trader at a desk that sold delta-one derivatives on listed indices (think swaps, ETFs). There is a LOT to do:   buy/ sell stocks according to redemptions or new orders; manage the currency exposure; indices rebalance their composition everyday based on stock corporate actions, dividends and index reviews - you need to be aware of each and everyone and rebalance your portfolio to account for it; manage your inventory to get the best repo rates possible; trade single stock swaps with foreign counterparties to get access to better tax rates on dividends; when you have a big order where certain stock orders may not get filled - you have to create a strategy for managing that risk; sometimes you hedge your positions using futures that expire every three months in which case you need to figure out the best times to roll your expiring futures; i could go on and on.  Basically, since the profit margins are so low, the market so competitive for such vanilla products, and the volumes so high, you have to really make your processes super efficient and error-proof. Trust me, there is a lot to be done! To add a bit to Daniel Anderson's great answer, if you want to 'peek' at what a the set of bid and ask spreads looks like, the otc market page could be interesting (NOTE:  I'm NOT recommending that you trade Over The Counter.  Many of these stocks are amusingly scary):  http://www.otcmarkets.com/stock/ACBFF/quote You can see market makers essentially offering to buy or sell blocks of stock at a variety of prices. "I think it's apt to remind that there's no shortcuts, if someone thinks about doing FX  fx: - negative sum game (big spread or commissions) - chaos theory description is apt - hard to understand costs (options are insurance and for every trade there is equivalent option position - so unless you understand how those are priced, there's a good chance you're getting a ""sh1tty deal"" as that Goldman guy famously said) - averaging can help if timing is bad but you could be just getting deeper into the ""deal"" I just mentioned and giving a smarter counterparty your money could backfire as it's the ""ammo"" they can use to defend their position.  This doesn't apply to your small hedge/trade? Well that's what I thought not long ago too! That's why I mentioned chaos theory. If you can find a party to hedge with that is not hedging with someone who eventually ends up hedging with JPM/Goldman/name any ""0 losing days a year"" ""bank"".. Then you may have a point. And contrary to what many may still think, all of the above applies to everything you can think of that has to do with money. All the billions with 0-losing days need to come from somewhere and it's definitely not coming just from couple FX punters." "Basically, your question boils down to this: Where and how do I squeeze the stock market so that within time period X, it will make me Y dollars. (Where I'm emotionally attached to the Y figure because I recently lost it, and X is ""as soon as possible"".) To make money on the stock market (in a quasi-guaranteed way), you have to adjust X and Y so that they are realistic. For instance, let X be twenty-five years, and Y be ""7% annual return"". Small values of X are risky, unless X is on the order of milliseconds and you have a computer program working for you. To mitigate some of the risk of short term trading, you have to treat trading seriously and study like mad: study the stock market in general, and not only that, but carefully research the companies whose stocks you are buying. Work actively to discover stocks which are under-valued relative to the performance of their corporation, and which might correct upward relative to the performance of similar stocks. Always have an exit strategy for every position and stick to it. Use instruments like ""trailing stops"": automatic tracking which follows a price in one direction, and then produces an order to close the position when the price reverses by a certain amount." "The Auction Market is where investors such you and me, as well as Market Makers, buy and sell securities.  The Auction Markets operate with the familiar bid-ask pricing that you see on financial pages such as Google and Yahoo.  The Market Makers are institutions that are there to provide liquidity so that investors can easily buy and sell shares at a ""fair"" price. Market Makers need to have on hand a suitable supply of shares to meet investor demands.  When Market Makers feel the need to either increase or decrease their supply of a particular security quickly, they turn to the Dealer Market. In order to participate in a Dealer Market, you must be designated a Market Maker.  As noted already, Market Makers are dedicated to providing liquidity for the Auction Market in certain securities and therefore require that they have on hand a suitable supply of those securities which they support.  For example, if a Market Maker for Apple shares is low on their supply of Apple shares, then will go the Dealer Market to purchase more Apple shares.  Conversely, if they are holding what they feel are too many Apple shares, they will go to the Dealer Market to sell Apple shares.  The Dealer Market does operate on a bid-ask basis, contrary to your stated understanding. The bid-ask prices quoted on the Dealer Market are more or less identical to those on the Auction Market, except the quote sizes will be generally much larger. This is the case because otherwise, why would a Market Maker offer to sell shares to another Market Maker at a price well below what they could themselves sell them for in the Auction Market.  (And similarly with buy orders.)  If Market Makers are generally holding low quantities of a particular security, this will drive up the price in both the Dealer Market and the Auction Market. Similarly, if Market Makers are generally holding too much of a particular security, this may drive down prices on both the Auction Market and the Dealer Market."
