Is it better to buy put options or buy an inverse leveraged ETF?
You don't have to think it is going down, it is currently trending down as on a weekly chart there are lower lows and lower highs. Until there is a higher low with confirmation of a higher high, the downtrend will continue.  The instrument you use to profit from a market drop depends on your risk profile, the time frame you are looking at, and your trading plan and risk management. With a put option your loss is limited to your initial premium and your potential profits can be quite large compared to the premium paid, however your timeframe is limited to the expiry of the option. You could buy a longer dated option but this will cost more in the premium you pay. With inverse ETF you are not restricted by an expiry date, but if you don't have appropriate risk management in place your potential losses can be large. With a leveraged inverse ETF again you are not restricted by an expiry date, you can potentially make higher percentage profits than with an standard ETF. but once again your losses can be very large (larger than you initial investment) if you don't have appropriate risk management in place. "Depends on how far down the market is heading, how certain you are that it is going that way, when you think it will fall, and how risk-averse you are.  By ""better"" I will assume you are trying to make the most money with this information that you can given your available capital. If you are very certain, the way that makes the most money for the least investment from the options you provided is a put.  If you can borrow some money to buy even more puts, you will make even more.  Use your knowledge of how far and when the market will fall to determine which put is optimal at today's prices.  But remember that if the market stays flat or goes up you lose everything you put in and may owe extra to your creditor.  A short position in a futures contract is also an easy way to get extreme leverage.  The extremity of the leverage will depend on how much margin is required.  Futures trade in large denominations, so think about how much you are able to put to risk. The inverse ETFs are less risky and offer less reward than the derivative contracts above.  The levered one has twice the risk and something like twice the reward.  You can buy those without a margin account in a regular cash brokerage, so they are easier in that respect and the transactions cost will likely be lower. Directly short selling an ETF or stock is another option that is reasonably accessible and only moderately risky.  On par with the inverse ETFs." The only use of options that I will endorse is selling them. If you believe the market is going down then sell covered, out of the money, calls.  Buying calls or buying puts usually wastes money. That is because of a quality called Theta. If the underlying security stays the same the going price of an option will decrease, every day, by the Theta amount.  Think of options as insurance. A person only makes money by selling insurance, not by buying it.
"You could buy options. I do not know what your time horizon is but it makes all the difference due to theta burn. There are weekly, monthly, quarterly, yearly and even longer duration options called leaps. You have decided how long of a time frame. You also have to see what the implied volatility is for the underlying because if you think hypothetically that the price of the spy is 100 dollars currently. Today is hypothetically a Thursday and you buy a weekly option expiring on Friday ( the next day) of strike 100.5 and the call option is priced at .55 cents and you buy it. This means that the underlying has to move .5 dollars in one day to be considered in the money but at time 0, the option should only be worth its intrinsic value which is the underlying, (Say the SPY moved 55 cents up from 100 to 100.55), (100.55) minus the strike (100.5) = 5 cents, so if you payed 55 cents and one day later at expiration its worth 5 cents ,you lost almost 91% of your money, rather with buying and holding you lose a lot less. The leverage is on a 10x scale typically. That is why timing is so important. Anyone can say x stock is going to go up in the future, but if you know ****when**** you can make a killing if it is not already priced into the market. Another thing you can do is figure out how much MSFT contributes to the SPX movement in terms of points. What does a 1% move in MSFT doto SPX. If you can calculate that and you think you know where MSFT is going, you can just trade the spy options synthetically as if it were microsoft. You could also buy msft stock on margin as a retail investor, but be careful. Like Rhaskett said, look into an etf that has microsoft. The nasdaq has a nasdaq-100 which microsoft is in called the triple Q. The ticker is qqq. PowerShares QQQ™, formerly known as ""QQQ"" or the ""NASDAQ- 100 Index Tracking Stock®"", is an exchange-traded fund based on the Nasdaq-100 Index®. Best of luck and always understand what you are buying before you buy it, JL" There are multiple ETFs which inversely track the common indices, though many of these are leveraged.  For example, SDS tracks approximately -200% of the S&P 500.  (Note: due to how these are structured, they are only suitable for very short term investments) You can also consider using Put options for the various indices as well.  For example, you could buy a Put for the SPY out a year or so to give you some fairly cheap insurance (assuming it's a small part of your portfolio). One other option is to invest against the market volatility.  As the market makes sudden swings, the volatility goes up; this tends to be true more when it falls than when it rises.  One way of invesing in market volatility is to trade options against the VIX. "The most fundamental answer is that when you short a stock (or an ETF), you short a specific number of shares on a specific day, and you probably don't adjust this much as the price wobbles goes up and down. But an inverse fund is not tied to a specific start date, like your own transaction is.  It adjusts on an ongoing basis to maintain its full specified leverage at all times.  If the underlying index goes up, it has to effectively ""buy in"" because its collateral is no longer sufficient to support its open position.  On the other hand, if the underlying index goes down, that frees up collateral which is used to effectively short-sell more of the underlying.  So by design it will buy high and sell low, and so any volatility will pump money out of the fund. I say ""effectively"" because inverse funds use derivatives and contracts, rather than actually shorting the underlying security.   Which brings up the less fundamental issue.  These derivatives and contracts are relatively opaque; the counter-parties are in it for their own benefit, not yours; and the people who run the fund get their expenses regardless of how you do, and they are hard for you to monitor.  This is a hazardous combination." "To understand the VXX ETF, you need to understand VIX futures, to understand VIX futures you need to understand VIX, to understand VIX you need to understand options pricing formulas such as the ""Black Scholes"" formula Those are your prerequisites. Learn at your own pace. Short Answer: When you buy VXX you are buying the underlying are front month VIX futures. Limited by the supply of the ETF's NAV (Net Asset Value) units. It is assumed that the ETF manager is actually buying and selling more VIX front month futures to back the underlying ETF. Long Answer: Assume nobody knows what an options contract should be worth. Therefore formulas have been devised to standardize how to price an options contract. The Black-Scholes formula is widely used, one of the variables in this formula is ""Implied Volatility"", which basically accounts for the mispricing of options when the other variables (Intrinsic Value, delta, gamma, theta...) don't completely explain how much the option is worth. People are willing to pay more for options when the perception is that they will be more profitable, ""implied volatility"" tracks these changes in an option's demand, where the rest of the black-scholes formula creates a price for an option that will always be the same. Each stock in the market that also trades standardized options will have implied volatility which can be computed from the price of those options. The ""Volatility Index"" (VIX), looks at the implied volatility of MANY STOCK's options contracts. Specifically the ""implied volatility of out the money puts on the S&P 500"". If you don't know what that quoted part of the sentence means, then you have at least five other individual questions to ask before you re-read this answer and understand the relevance of these followup questions: Why would people buy out-the-money puts on the S&P 500? Why would people pay more for out-the-money puts on the S&P 500 on some days and pay less for them on other days? This is really the key to the whole puzzle. Anyway, now that we have this data, people wanted to speculate on the future value of the VIX. So VIX futures contracts began trading and with it there came a liquid market. There doesn't need to be anything physical to back a financial product anymore. A lot of people don't trade futures, retail investors have practically only heard of ""the stock market"". So one investment bank decided to make a fund that only holds VIX futures that expire within a month. (front month futures). They split that fund up into shares and listed it on the stock market, like alchemy the VXX was formed. Volatility studies are fascinating, and get way more complex than this now that the VXX ETF also has liquid options contracts trading on it too, and there are leveraged VIX ETF funds that also trade options" First, make sure you understand the objective of an ETF.  In some cases, they may use leverage to get a multiple of the index's return that is different than 1.  Some may be ultra funds that go for double the return or double the inverse of the return and thus will try to apply the appropriate leverage to achieve that return. Those that use physical replication can still have a small portion be used to try to minimize the tracking error as there is something to be said for what kind of tracking error do you accept as the fund's returns may differ from the index by some measure. Yes.  For example, if you were to have a fund that had a 50% and -50% return in back to back periods, what would your final return be?  Answer: -25%, which if you need to visualize this, take $1 that then becomes $1.50 by going up 50% and then becomes $.75 by going down 50% in a compounded fashion.  This is where you have to be careful of the risks of leverage as those returns will compound in a possibly negative way. I wouldn't use it to take leverage unless you don't mind loosing your entire investment (this is a possibility as shares are already quite volatile). However, you don't have to take leverage and still trade CFDs. Benefits of doing so: Disadvantages: 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. "You said your strategy was to put it into a index fund.  But then you asked about setting  stock limits.   I'm confused. Funds usually trade at their price at the end of the day, so you shouldn't try to time this at all. Just place your order. If you are buying ETFs, there is going to be so much volume on the market that your small trade is going to have no impact on the price. You should just place a market order. A market order is an order to buy or   sell a stock at the current market   price. A limit order is an order to buy or   sell a security at a specific price. In the US, when you place a trade with any broker, you can either place a limit order or a market order.  A market order just fills your order with the next best sellers in line.  If you place an order for 100 shares, the sellers willing to sell 100 shares at the lowest price will be matched with your order (sometimes you may get 50 shares at one price and 50 shares at a slightly different price).    If your stock has a lot of volatility and you place a market order for a small amount of shares,  you will get the best price. If you place a limit order, you specify the price at which you want to buy shares.  Your order will then only be filled with sellers willing to sell at that price or lower (i.e. they must be at least as good as you specified).  This means you could place an order at a limit that does not get filled (the stock could move in a direction away from your limit price).  If you really want to own the stock, you shouldn't use a limit order.  You shouldn't only use a limit order if you want to tell your broker ""I will only buy this stock at this price or better.""  p.s. Every day that passes is NOT a waste.  It's just a day that you've decided investing in cash is safer than investing in the market."
