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.
"Below is just a little information on short selling from my small unique book ""The small stock trader"":  Short selling is an advanced stock trading tool with unique risks and rewards. It is primarily a short-term trading strategy of a technical nature, mostly done by small stock traders, market makers, and hedge funds. Most small stock traders mainly use short selling as a short-term speculation tool when they feel the stock price is a bit overvalued. Most long-term short positions are taken by fundamental-oriented long/short equity hedge funds that have identified some major weaknesses in the company. There a few things you should consider before shorting stocks: Despite all the mystique and blame surrounding short selling, especially during bear markets, I personally think regular short selling, not naked short selling, has a more positive impact on the stock market, as: Lastly, small stock traders should not expect to make significant profits by short selling, as even most of the great stock traders (Jesse Livermore, Bernard Baruch, Gerald Loeb, Nicolas Darvas, William O’Neil, and Steven Cohen,) have hardly made significant money from their shorts. it is safe to say that odds are stacked against short sellers. Over the last century or so, Western large caps have returned an annual average of between 8 and 10 percent while the returns of small caps have been slightly higher.  I hope the above little information from my small unique book was a little helpful! Mika (author of ""The small stock trader"")" An option, by definition, is a guess about the future value of the stock. If you guess too aggressively, you lose the purchase price of the option; if you guess too conservatively, you may not take the option or may not gain as much as you might have. You need to figure out what you expect to happen, and how confident you are about it, against the cost of taking the option -- and be reasonably confident that the change in the stock's value will be at least large enough to cover the cost of buying into the game. Opinion: Unless you're comfortable with expectation values and bell curves around them, it's significantly easier to lose money on options than to profit on them. And I'm not convinced that even statisticians can really do this well. I've always been told that the best use for options is hedging an investment you've already made; treating them as your primary bet is gambling, not investment. "At the most fundamental level, every market is comprised of buyers and selling trading securities. These buyers and sellers decide what and how to trade based on the probability of future events, as they see it. That's a simple statement, but an example demonstrates how complicated it can be. Picture a company that's about to announce earnings. Some investors/traders (from here on, ""agents"") will have purchased the company's stock a while ago, with the expectation that the company will have strong earnings and grow going forward. Other agents will have sold the stock short, bought put options, etc. with the expectation that the company won't do as well in the future. Still others may be unsure about the future of the company, but still expecting a lot of volatility around the earnings announcement, so they'll have bought/sold the stock, options, futures, etc. to take advantage of that volatility.  All of these various predictions, expectations, etc. factor into what agents are bidding and asking for the stock, its associated derivatives, and other securities, which in turn determines its price (along with overall economic factors, like the sector's performance, interest rates, etc.) It can be very difficult to determine exactly how markets are factoring in information about an event, though. Take the example in your question. The article states that if market expectations of higher interest rates tightened credit conditions... In this case, lenders could expect higher interest rates in the future, so they may be less willing to lend money now because they expect to earn a higher interest rate in the future. You could also see this reflected in bond prices, because since interest rates are inversely related to bond prices, higher interest rates could decrease the value of bond portfolios. This could lead agents to sell bonds now in order to lock in their profits, while other agents could wait to buy bonds because they expect to be able to purchase bonds with a higher rate in the future.  Furthermore, higher interest rates make taking out loans more expensive for individuals and businesses. This potential decline in investment could lead to decreased revenue/profits for businesses, which could in turn cause declines in the stock market. Agents expecting these declines could sell now in order to lock in their profits, buy derivatives to hedge against or ride out possible declines, etc. However, the current low interest rate environment makes it cheaper for businesses to obtain loans, which can in turn drive investment and lead to increases in the stock market. This is one criticism of the easy money/quantitative easing policies of the US Federal Reserve, i.e. the low interest rates are driving a bubble in the stock market. One quick example of how tricky this can be. The usual assumption is that positive economic news, e.g. low unemployment numbers, strong business/residential investment, etc. will lead to price increases in the stock market as more agents see growth in the future and buy accordingly. However, in the US, positive economic news has recently led to declines in the market because agents are worried that positive news will lead the Federal Reserve to taper/stop quantitative easing sooner rather than later, thus ending the low interest rate environment and possibly tampering growth.  Summary: In short, markets incorporate information about an event because the buyers and sellers trade securities based on the likelihood of that event, its possible effects, and the behavior of other buyers and sellers as they react to the same information. Information may lead agents to buy and sell in multiple markets, e.g. equity and fixed-income, different types of derivatives, etc. which can in turn affect prices and yields throughout numerous markets." "Some technical indicators (e.g. Williams %R) indicate whether the market is overbought or oversold.   ... Every time a stock or commodity is bought, it is also sold. And vice versa. So how can anything ever be over-bought or over-sold? But I'm sure I'm missing something. What is it? You're thinking of this as a normal purchase, but that's not really how equity markets operate. First, just because there are shares of stock purchased, it doesn't mean that there was real investor buyer and seller demand for that instrument (at that point in time).  Markets have dedicated middlemen called Market Makers, who are responsible to make sure that there is always someone to buy or sell; this ensures that all instruments have sufficient liquidity.  Market Makers may decide to lower their bid on a stock based on a high number of sellers, or raise their ask for a high number of buyers. During an investor rush to buy or sell an instrument (perhaps in response to a news release), it's possible for Market Makers to accumulate a large number of shares, without end-investors being involved on both sides of the transaction.  This is one example of how instruments can be over-bought or over-sold. Since Williams %R creates over-bought and over-sold signals based on historical averages of open / close prices, perhaps it's better to think of these terms as ""over-valued"" and ""under-valued"".  Of course, there could be good reason for instruments to open or close outside their expected ranges, so Williams %R is just a tool to give you clues... not a real evaluation of the instrument's true value." The first thing that I learned the hard way (by trying my hand at actual options trading) is that liquidity matters. So few people are interested in trading the same options that I am that it is easy to get stuck holding profitable contracts into expiration unless I offer to sell them for a lot less than they are worth.  I also learned that options are a kind of insurance,and no one makes money (in the long run) buying insurance.  So you can use options to hedge and thereby prevent losses, but you also blunt your gains.  Edit: IMO,options (in the long run) only make money for the brokers as you pay a commission both on the buy and on the sell. With my broker the commission on options is higher than the commission on stocks (or ETFs). "First, your question contains a couple of false premises: Options in the U.S. do not trade on the NYSE, which is a stock exchange.  You must have been looking at a listing from an options exchange. There are a handful of options exchanges in the U.S., and while two of these have ""NYSE"" in the name, referring to ""NYSE"" by itself still refers to the stock exchange. Companies typically don't decide themselves whether options will trade for their stock.  The exchange and other market participants (market makers) decide whether to create a market for them. The Toronto Stock Exchange (TSX) is also a stock exchange.  It doesn't list any options.  If you want to see Canadian-listed options on equities, you're looking in the wrong place. Next, yes, RY does have listed options in Canada. Here are some.  Did you know about the Montreal Exchange (MX)?  The MX is part of the TMX Group, which owns both the Toronto Stock Exchange (TSX) and the Montreal Exchange. You'll find lots of Canadian equity and index options trading at the MX.  If you have an options trading account with a decent Canadian broker, you should have access to trade options at the MX. Finally, even considering the existence of the MX, you'll still find that a lot of Canadian companies don't have any options listed.  Simply: smaller and/or less liquid stocks don't have enough demand for options, so the options exchange & market makers don't offer any. It isn't cost-effective for them to create a market where there will be very few participants." There are a number reasons to hedge a position.  Here are some of the more common: "So, yes, you may be having the inevitable epiphany where you realize that options can synthetically replicate the same risk profile of owning stock outright. Allowing you to manipulate risk and circumvent margin requirement differences amongst asset classes. Naked short puts are analogous to a covered call, but may have different (lesser) margin requirements. This allows you to increase your risk, and the broker has to account for that. The broker's clientele might not understand all the risks associated with that much leverage and so may simply consider it risky ""for your protection"""
