Is there extra risk in owning an ADR vs. the underlying stock?
Yes, the ADR will trade on a separate exchange from the underlying one, and can (and does) see fluctuations in price that do not match the (exchange corrected) fluctuations that occur in the original market. You are probably exposing yourself to additional risk that is related to:
This is not right. Inferring the employee stock pool’s takeaway is not as easy as just taking a fraction of the purchase price. As an example, that wouldn’t account for any preferred returns of other ownership classes, among other things.   All considered though, it’s reasonable to assume that the employee stock pool will get some premium. Best of luck. Your three options are: Options 2 and 3 are obviously identical (other than transaction costs), so if you want to keep the stock, go for option 1, otherwise, go for option 3 since you have the same effect as option 2 with no transaction costs.  The loss will likely also offset some of the other short term gains you mentioned. The economic effect of a CFD from your point of view is very close to the effect of owning the stock. If the stock goes up, you make money. If it goes down you lose money. If it pays a dividend, you get that dividend. You'll typically pay commission for buying and selling the CFDs in a similar way to the commission on stock purchases, though one of the advertised advantages of CFDs is that the commission will be lower. They also often have tax advantages, for example in the UK you don't have to pay stamp duty on CFDs. In theory you are exposed to credit risk on the CFD issuer, which you aren't with the real stocks: if the issuer goes bankrupt, you may lose any money you have invested regardless of how well the stock has performed. It's certainly similar to a bet, but not much more so than investing directly in the stock. In practice the issuer of the CFDs is likely to hedge its own exposure by actually buying the underlying stocks directly, but they can aggregate across lots of contracts and they would tolerate some unhedged exposure to the stock, so they can cut down on the transaction fees. You also won't get the same voting rights as the underlying stock would grant you. "There are some useful answers here, but I don't think any of them are quite sufficient.  Yes, there are some risks involved in CFD trading, but I will try and give you information so you can make your own decision. Firstly, Cyprus is part of the EU, which gives it a level of credibility.  I'm not saying it's the safest or most well regulated market in the world, but that in itself would not particularly scare me away.  The far more important issue here is the risk of using CFDs and of eToro themselves. A Contract for Difference is really just a specialization of an Equity Swap.  It is in no way like owning a real stock.  When you purchase shares of a company you own a real Asset and are usually entitled to dividends and voting rights.  With a CFD, what you own is one side of a Swap contract.  You have a legal agreement between yourself and eToro to ""swap"" the return earned on the underlying stock for whatever fees eToro decide to charge.  As already mentioned, CFDs are not available to US citizens. Equity swaps have many benefits in financial markets.  They can allow access to restricted markets by entering into swaps with banks that have the necessary licenses to trade in places like China.  Many ""synthetic"" ETFs use them in Europe as a way to minimize tracking error as the return is guaranteed by the swap counterparty (for a charge). They also come with one signficant risk: counterparty credit risk.  When trading with eToro, for as long as your position is open, you are at risk of eToro going bankrupt.  If eToro failed, you do not actually own any stocks, you only own swap contracts which are going to be worthless if eToro ceased to exist. CFDs also have an ongoing cost to maintain the open position.  This makes them less suitable for buy and hold strategies as those ongoing costs will eat into your returns.  It's also not clear whether you would receive any dividends paid by the stock, which make up a significant proportion of returns for buy and hold investors.  eToro's website is fairly non-committal: eToro intends to offer a financial compensation representing the dividends which will be allocated on stocks, to the extent such dividends shall be available to eToro. All of these points expose what CFDs are really for - speculating on the stock market, or as I like to call it: gambling.  If you want to invest in stocks for the long term, CFDs are a bad idea - they have high ongoing costs and the counterparty risk becomes significant.  Wait until you have enough money and then buy the real thing.  Alternatively, consider mutual funds which will allow you to purchase partial shares and will ensure your investment is better diversified across a large number of stocks.  If however, you want to gamble and only keep your position open for a short time, these issues may not be of concern to you. There's nothing wrong with gambling, it can be fun, many people gamble in casinos or on football matches - but bear in mind that's what CFDs are for.  CFDs were in fact originally created for the UK market as a way to avoid paying capital gains tax when making short term speculative trades.  However, if you are going to gamble, make sure you're not putting any more than 1% of your net worth at risk (0.1% may be a better target). There are a few other ways to take a position on stocks using less money than the share price: Fortunately, eToro do not allow leveraged purchase of stocks so you're reasonably safe on this point.  They claim this is because of their 'responsible trading policy', although I find that somewhat questionable coming from a broker that offers 400:1 leverage on FX pairs. One final word on eToro's ""social trading"" feature.  A few years ago I was in a casino playing Blackjack.  I know nothing about Blackjack, but through sheer luck of the draw I managed to treble my money in a very small amount of time.  Seeing this, a person behind me started ""following"" me by putting his chips down on my seat.  Needless to say, I lost everything, but amazingly the person behind me got quite annoyed and started criticizing my strategy.  The idea of following other people's trades just because they've been lucky in the past sounds entirely foolish to me.  Remember the warning on every mutual fund: Past performance does not guarantee future returns" You own the stock at $29.42 At $40, the stocks is called at $26. You can't add the call premium, as it's already accounted for. The trade is biased towards being bearish on the stock. (I edited and added the graph the evening I answered)  Not the pretiest graph, but you get the idea. With that $29.42 cost, you are in the money till about $30, then go negative until the most you lose is $3.42. Yes, that's the risk. If the stock is bouncing around a lot your options could get assigned.  If it heads south you now are the proud owner of more of a falling stock.  It's good that you're looking to understand the risks of an investment method.  That's important no matter what the method is. &gt;If we are looking to offset risk in location A where we are not able to buy forward with location W, and they are the same commodity is this even a common practice in risk management?  Let me prephase this by saying I don't do work directly in this area, but sometimes I analyze what's happening in less liquid markets compared to more liquid markets in various commodities to get a better sense of the supply and demand dynamics of the market.   It's normal - but just looking at the ratios - it looks like the spread is quite volatile - it looks like the price at location W went from trading at 130% of location A to 170% of the price at location A. (I also don't use R so I don't know which time period was the start and which was the end)  What moved in one direction can definitely reverse. If you don't know what is driving this movement in the spread then adding the hedge could be riskier than not having any hedge on. And there are scenarios where the price of the commodity you want to buy at location A is going to rise towards the price at liquid location W and if you are unable to buy it and store it then there isn't much you can do to hedge your company's exposure. "You might consider learning how the ""matching"" or ""pairing"" system in the market operates.  The actual exchange only happens when both a buyer and a seller overlap their respect quotes.   Sometimes orders ""go to market"" for a particular volume.  Eg get me 10,000 Microsoft shares now.  which means that the price starts at the current lowest seller, and works up the price list until the volume is met.  Like all market it trades, it has it's advantages, and it's dangers.  If you are confident Microsoft is going to bull, you want those shares now, confident you'll recoup the cost.  Where if you put in a priced order, you might get only none or some shares. Same as when you sell.  If you see the price (which is the price of the last completed ""successful"" trade.  and think ""I'm going to sell 1000 shares"". then you give the order to the market (or broker), and then the same as what happened as before.  the highest bidder gets as much as they asked for, if there's still shares left over, they go to the next bidder, and so on down the price... and the last completed ""successful"" trade is when your last sale is made at the lowest price of your batch. If you're selling, and selling 100,000 shares. And the highest bidder wants 1,000,000 shares you'll only see the price drop to that guys bid.  Why will it drop (off the quoted price?).  Because the quoted price is the LAST sale, clearly if there's someone still with an open bid on the market...then either he wants more shares than were available (the price stays same), or his bid wasn't as high as the last bid (so when you sale goes through, it will be at the price he's offering).   Which is why being able to see the price queues is important on large traders. It is also why it can be important put stops and limits on your trades, een through you can still get gapped if you're unlucky.  However putting prices (""Open Orders"" vs ""(at)Market Orders"") can mean that you're sitting there waiting for a bounce/spike while the action is all going on without you). safer but not as much gain (maybe ;) ) that's the excitement of the market, for every option there's advantages...and risks... (eg missing out) There are also issues with stock movement, shadowing, and stop hunting, which can influence the price. But the stuff in the long paragraphs is the technical reasons." Stock B could be considered to be more risky because it seems to be more volatile - sharp rises on large volume increases can easily be followed by sharp drops or by further rises in the start of a new uptrend.  However, if both A and B are trading on low volume in general, they can both be more on the risky side due to having relatively low liquidity, especially if you buy a large order compared to the average daily volume. But just looking at the criteria you have included in your question is not enough to determine which stock is riskier than the other, and you should look at this criteria in combination with other indicators and information about each stock to obtain a more complete picture. "Risk is the capital you have staked in pursuit of profit. The danger is that you lose what you have risked.  For some bets (risks), you can get insurance to cover for losses.  Now the ""game"" of Landlord and Tenant requires you to play fully by the rules set forth by your legislators. In your case, that is the legislators of the State of Texas. Without knowing those rules, you could be liable (open to civil prosecution) for violating those rules. Tenants could be savvy to those rules or savvy enough to hire someone, a lawyer, who knows those rules. As well, in the game of Landlord and Tenant, you must ascertain the creditworthiness of your would-be tenant. If the tenant fails to pay rent, that tenant can detain the residence. You will incur additional outlays to gain possession of your property (ownership in your rental). Now the game of Landlord vs Landlord is different. You can't pick up houses easily enough and even if you could, likely the expense of doing so could wipe out any would profits from having the house as a rental. So, in Landlord vs Landlord, you get constrained by where your rental sits. Thus you must forecast what will the neighborhood look like in five, ten, fifteen years." The quotes on JSE are for 100 share lots.  The quotes on NYSE are for single shares.  That still leaves some price difference, but much less than you calculated. (EDIT: Equivalently, the price is quoted in 1/100th of a Rand.  The Reuter's listing makes this explicit since the price is listed as ZAc rather than ZAR.  http://www.reuters.com/finance/stocks/overview?symbol=HARJ.J) As noted in the other answer currently up, NYSE is quoting American Depositary Receipts (ADRs) for this company, which is not directly its stock.  The ADR in this case, if you check the prospectus, is currently 1 share of the ADR = 1 share of the stock on its home market.  A US institution (in this case it looks like BNY Mellon) is holding shares of stock to back each ADR. Arbitrage is possible and does happen.  It's not perfect though, because there are a variety of other cost and risk factors that need to be considered.  There's a good review here: Report by JP Morgan Some summary points: That's not 100% correct, as some leveraged vehicles choose to re-balance on a monthly basis making them less risky (but still risky).  If I'm not mistaken the former oil ETN 'DXO' was a monthly re-balance before it was shut down by the 'man' Monthly leveraged vehicles will still suffer slippage, not saying they won't.  But instead of re-balancing 250 times per year, they do it 12 times.   In my book less iterations equals less decay. Basically you'll bleed, just not as much.  I'd only swing trade something like this in a retirement account where I'd be prohibited from trading options. Seems like you can get higher leverage with less risk trading options, plus if you traded LEAPS, you could choose to re-balance only once per year. Typically the settlement price for a financial instrument (such as AAPL stock) underlying a derivative contract is determined from the average price of trading in that instrument during some short time window specified by the exchange offering the derivative.  (Read the fine print on your contract to learn the exact date and time of that settlement period.) Because it's in an exchange's best interest to appear as fair as possible, the exchange will in general pick a high-volume period of time -- such as the close of trading on the expiry date -- in which to determine the settlement price. Now, the expiry date/time may be different from the last time at which the option can be traded, which may be different from the underlying settlement time.  For example, most US equity options currently expire on the Saturday following the third Friday of the month, whereas they can last be traded at end-of-day on the third Friday of the month, and the settlement period may be at a slightly different time on the third Friday of the month.  (Again, read the contract to know for sure.)  Moreover, your broker may demand to know whether you plan to exercise the option at an even earlier date/time. So, to answer your question: After-hours trading can only affect the settlement price of an underlying instrument if the exchange in question decides that the settlement period should happen during after-hours trading.  But since no exchange that wants to stay in business would possibly do that, the answer is no. Contract expiry time, contract exercise time, final contract trading time, and underlying settlement time may all fall at different dates/times.  The important one for your question is settlement time. Late to the party, but it's just improving your cost basis in a defined risk trade even further. If you want to put up less risk capital but want to test the waters, this can be one way to do it. Another could be buying cheap OTM butterflies or financing a further otm option with the basis reduction from the debit spread if you want to gamble a bit further and venture into 15-20 delta positions. Usually, I am doing debit spreads with a buying atm and selling a couple strikes further otm or at least at the most liquid strikes, but if it's a high flier, it can be disappointing, but a good trade. If you're more of a contrarian in where you buy your calls/puts, it's absolutely a good way to lessen your risk on a calculated bet. Liquidity on dual listed equities is rarely the same on both exchanges. More liquidity means you would typically get a better price assuming you execute the trades using the same order types. It's recommended to trade where the liquidity is greater unless your trading method benefits somehow from it being lower. It's important to remember that some ADRs (some European companies listed in US) have ADR fees which vary. USD/EUR transaction fees are low when using a decent broker but you're obviously participating in the currency risk.
