Does SIPC protect securities purchased in foreign exchanges?
I'll give it a shot, even though you don't seem to be responding to my comment. SIPC insures against fraud or abuse of its members. If you purchased a stock through a SIPC member broker and it was held in trust by a SIPC member, you're covered by its protection. Where you purchased the stock - doesn't matter. There are however things SIPC doesn't cover. That said, SIPC members are SEC-registred brokers, i.e.: brokers operating in the USA. If you're buying on the UK stock exchange - you need to check that you're still operating through a US SIPC member. As I mentioned in the comment - the specific company that you mentioned has different entities for the US operations and the UK operations. Buying through them on LSE is likely to bind you with their UK entity that is not SIPC member. You'll have to check that directly with them. "I have received a response from SIPC, confirming littleadv's answer: For a brief background, the protections available under the Securities   Investor Protection Act (""SIPA""), are only available in the context of   a liquidation proceeding of a SIPC member broker-dealer and relate to   the ""custody"" of securities and related cash at the SIPC member   broker-dealer. Thus, if a SIPC member broker-dealer were to fail at a   time when a customer had securities and/or cash in the custody of the   SIPC member broker-dealer, in most instances it would be SIPC's   obligation to restore those securities and cash to the customer,   within statutory limits. That does not mean, however, that the   customer would necessarily receive the original value of his or her   purchase. Rather, the customer receives the security itself and/or the   value of the customer's account as of the day that the liquidation   commenced. SIPC does not protect against the decline in value of any   security. In a liquidation proceeding under the SIPA, SIPC may advance   up to $500,000 per customer (including a $250,000 limit on cash in the   account). Please note that this protection only applies to the extent that you   entrust cash or securities to a U.S. SIPC member. Foreign broker   dealer subsidiaries are not SIPC members. However, to the extent that   any assets, including foreign securities, are being held by the U.S.   broker dealer, the assets are protected by SIPC. Stocks listed on the   LSE are protected by SIPC to the extent they are held with a SIPC   member broker dealer, up to the statutory limit of $500,000 per   customer. As I mentioned in the comments, in the case of IB, indeed they have a foreign subsidiary, which is why SIPC does not cover it (rather they are insured by Lloyds of London for such cases)."
All transactions involving fraud or theft are void by their nature. Title to your money never changes hands.  You are entitled by law to have assets stolen from you returned to you. In cases of negligence or broker malfeasance, lawsuits or SIPC protection are your primary recourse. "Yes when I place an order with my broker they send it out to the exchange. - For individual investors, what are some cons and pros of trading on    the exchanges directly versus indirectly via brokers? I may be mistaken(I highly doubt it), but from my understanding you cannot trade directly through an exchange as a retail investor. BATS allows membership but it is only for  Your firm must be a registered broker-dealer, registered with a Self Regulatory Organization (SRO) and connected with a clearing firm. No apple (aapl) is listed on the NASDAQ so trades go through the NASDAQ for aapl. Caterpillar Inc (CAT) is listed on the NYSE so trades go through the NYSE.  The exchange you trade on is dependent on the security, if it is listed on the NYSE then you trade on the NYSE. As a regular investor you will be going through a broker. When looking to purchase a security it is more important to know about the company and less important to know what exchange it is listed on. Since there are rules a company must comply with for it to be listed on certain exchanges, it does make a difference but that is more the case when speaking about a stock listed Over the Counter(OTC) or NYSE. It is not important when asking NYSE or NASDAQ? Selecting a broker is something that's dependent on your needs. You should ask your self, ""whats important to me?"", ""Do I want apps(IE: iPhone, android)?"" ""Do I need fancy trading tools?"". Generally all the brokers you listed will most likely do the trick for you. Some review sites: Brokerage Review  Online Broker Review 2012 Barron's 2012 Online Broker Review" "A non-trading stock or non-marketable security or unlisted security is one that does not trade continually on an exchange. For tax purposes, this can mean a whole new ball of wax which I would prefer the experts address with an edit to this answer or a new answer. For financial accounting purposes, this is when, say, one owns shares in an unlisted corporation and should be treated very carefully less one delude oneself. For trading stock, the value can be known immediately by checking any valid data provider's price and marking to market.  For non-trading stock, the value has to be ""marked to model"".  This can get one into Enron sized trouble. In this case, it's best to either leave the value of the stock at the purchase price and recognize gains upon sale, use a price from another honest transaction by third parties which are most likely difficult to attain, or to use some shorthand measure like applying the market P/E. Be wary of strangely high figures for value from the purchase price by using a market average, and don't throw away the shares just yet if a strangely low one arises.  This method can lead to strange results." "To speak to this a little more broadly: apart from groups like hedge funds and other investors investing for purely speculative purposes, one of the major purposes of forwards (and, for that matter, futures) for companies in the ""real economy"" is to ""lock in"" a particular price in advance (or to reduce the risk of some kind of investment or transaction). Investopedia defines a currency forward as follows (with a few key points emphasized): [A currency forward is] a binding contract in the foreign exchange market that locks in the exchange rate for the purchase or sale of a currency on a future date. A currency forward is essentially a hedging tool that does not involve any upfront payment. The other major benefit of a currency forward is that it can be tailored to a particular amount and delivery period, unlike standardized currency futures. This can be a major advantage for planning and risk management purposes. For example, if I know I'm going to have to pay $1 million USD in the future and most of my revenue is in Euros, the actual amount I'll have to pay will vary based on the exchange rate between Euros and dollars. Thus, it's very worthwhile for me to be able to ""lock in"" a particular exchange rate so that I know exactly how much I'm going to pay relative to my projected revenue. The goal isn't necessarily to make money off the transaction (maybe they do, maybe they don't) as much as to reduce risk and improve planning ability. The fact that it doesn't involve an up-front payment is also a major advantage. It's usually a bad practice to ""sit on"" cash for a year if you can avoid it. Another key point: savings accounts pay less interest than inflation. If inflation is 3% and your savings account pays 1%, that looks remarkably like a guaranteed 2% loss to me." "Depends. The short answer is yes; HSBC, for instance, based in New York, is listed on both the LSE and NYSE. Toyota's listed on the TSE and NYSE. There are many ways to do this; both of the above examples are the result of a corporation owning a subsidiary in a foreign country by the same name (a holding company), which sells its own stock on the local market. The home corporation owns the majority holdings of the subsidiary, and issues its own stock on its ""home country's"" exchange. It is also possible for the same company to list shares of the same ""pool"" of stock on two different exchanges (the foreign exchange usually lists the stock in the corporation's home currency and the share prices are near-identical), or for a company to sell different portions of itself on different exchanges. However, these are much rarer; for tax liability and other cost purposes it's usually easier to keep American monies in America and Japanese monies in Japan by setting up two ""copies"" of yourself with one owning the other, and move money around between companies as necessary. Shares of one issue of one company's stock, on one exchange, are the same price regardless of where in the world you place a buy order from. However, that doesn't necessarily mean you'll pay the same actual value of currency for the stock. First off, you buy the stock in the listed currency, which means buying dollars (or Yen or Euros or GBP) with both a fluctuating exchange rate between currencies and a broker's fee (one of those cost savings that make it a good idea to charter subsidiaries; could you imagine millions a day in car sales moving from American dealers to Toyota of Japan, converted from USD to Yen, with a FOREX commission to be paid?). Second, you'll pay the stock broker a commission, and he may charge different rates for different exchanges that are cheaper or more costly for him to do business in (he might need a trader on the floor at each exchange or contract with a foreign broker for a cut of the commission)." It doesn't matter which exchange a share was purchased through (or if it was even purchased on an exchange at all--physical share certificates can be bought and sold outside of any exchange). A share is a share, and any share available for purchase in New York is available to be purchased in London. Buying all of a company's stock is not something that can generally be done through the stock market. The practical way to accomplish buying a company out is to purchase a controlling interest, or enough shares to have enough votes to bind the board to a specific course of action. Then vote to sell all outstanding shares to another company at a particular fixed price per share. Market capitalization is an inaccurate measure of the size of a company in the first place, but if you want to quantify it, you can take the number of outstanding shares (anywhere and everywhere) and multiply them by the price on any of the exchanges that sell it. That will give you the market capitalization in the currency that is used by whatever exchange you chose. Depends on the structure of the company and what shares are outstanding.  If the pink sheet stock has no voting power then buying all that stock doesn't get you any control at all.  On the other hand, if the outstanding shares only represent 20% of the company's overall shares, then buying all the shares isn't likely enough to have a controlling interest. Thus, you'll have to dig into the details.  If you want an example of where I'd have my doubts, look at Nestle's stock which has the ticker of NSRGY.  There can be companies that are structured with stock on multiple exchanges that can also be a challenge at times.  There is also something to be said if you own enough stock in a company that this has to be disclosed to the SEC when you buy more. Academic research into ADRs seems to suggest that pairs-trading ADRs and their underlying shares reveals that there certainly are arbitrage opportunities, but that in most (but not all cases) such opportunities are quickly taken care of by the market. (See this article for the mexican case, the introduction has a list of other articles you could read on the subject). In some cases parity doesn't seem to be reached, which may have to do with transaction costs, the risk of transacting in a foreign market, as well as administrative & legal concerns that can affect the direct holder of a foreign share but don't impact the ADR holder (since those risks and costs are borne by the institution, which presumably has a better idea of how to manage such risks and costs). It's also worth pointing out that there are almost always arbitrage opportunities that get snapped up quickly: the law of one price doesn't apply for very short time-frames, just that if you're not an expert in that particular domain of the market, it might as well be a law since you won't see the arbitrage opportunities fast enough. That is to say, there are always opportunities for arbitrage with ADRs but chances are YOU won't be able to take advantage of it (In the Mexican case, the price divergence seems to have an average half-life of ~3 days). Some price divergence might be expected: ADR holders shouldn't be expected to know as much about the foreign market as the typical foreign share holder, and that uncertainty may also cause some divergence. There does seem to be some opportunity for arbitrage doing what you suggest in markets where it is not legally possible to short shares, but that likely is the value added from being able to short a share that belongs to a market where you can't do that.
