For a single company listed in multiple exchanges in different countries, are the shares being offered the same?
"Yes and no.  There are two primary ways to do this.  The first is known as ""cross listing"". Basically, this means that shares are listed in the home country are the primary shares, but are also traded on secondary markets using mechanisms like ADRs or Globally Registered Shares. Examples of this method include Vodafone and Research in Motion. The second is ""dual listing"". This is when two corporations that function as a single business are listed in multiple places. Examples of this include Royal Dutch Shell and Unilever. Usually companies choose this method for tax purposes when they merge or acquire an international company. Generally speaking, you can safely buy shares in whichever market makes sense to you."
You can apply for Foreign currency accounts. But they aren't saving accounts by any means, but more like current accounts. Taking money out will involve charges. You have to visit the bank website to figure out what all operations can be performed on your account. Barclays and HSBC allow accounts in foreign currency. Other banks also will be providing the same services. Are there banks where you can open a bank account without being a citizen of that country without having to visit the bank in person Depends on country by country.  Are there any online services for investing money that aren't tied to any particular country? Get yourself a trading account and invest in foreign markets i.e. equities, bonds etc.  But all in all be ready for the foreign exchange risks involved in denominating assets in multiple currencies. Much of this is incorrect. Aetna owns Payflex for starters, and it's your EMPLOYER who decides which banks and brokers to offer, not Payflex. An HSA is a checking account with an investment account option after a minimum balance is met. A majority of U.S. employers only OFFER an HSA option but don't contribute a penny, so you're lucky you get anything.  The easy solution is just keep the money that is sent to your HSA checking account in your checking account, and once a year roll it over into a different bank's HSA. The vast majority of banks offer HSAs that have no ties to a particular broker (i.e. Citibank, PNC, Chase). I have all my HSA funds in HSA Bank which is online but services lots of employers. Not true that most payroll deductions or employer contributions go to a single HSA custodian (bank).  They might offer a single bank that either contracts with an investment provider or lets you invest anywhere. But most employers making contributions are large or mid-market employers offering multiple banks, and that trend is growing fast because of defined contribution, private exchanges and vendor product redesigns. Basically, nobody likes having a second bank account for their HSA when their home bank offers one. "listed simultaneously in New York, London, and maybe even some Asian markets - is this correct? If the exchanges are not connected, then in primary market the shares are listed. On other exchanges, the ""Depository Receipts"" are listed. i.e. the Company will keep say 100,000 shares with the primary stock exchange / depository. Based on this it would create new instruments ""Depository Receipts"". They can be 1:1 or whatever ratio. hypothetically, if I want to buy all of the company's stock Even if it is on one exchange, buying all stocks would trigger various regulatory aspects of Companies Act, or Stock Exchange rules. This is not simple or easy like clicking some buttons and buying everything. That is, let's say that in New York the company has listed 1000 shares, and in London only 10 shares, each worth 10 USD Market capitalization is sum of all outstanding shares into value." The S&P500 is an index, not an investment by itself.  The index lists a large number of stocks, and the value of the index is the price of all the stocks added together. If you want to make an investment that tracks the S&P500, you could buy some shares of each stock in the index, in the same proportions as the index.  This, however, is impractical for just about everyone. Index mutual funds provide an easy way to make this investment.  SPY is an ETF (exchange-traded mutual fund) that does the same thing. An index CFD (contract for difference) is not the same as an index mutual fund.  There are a number of differences between investing in a security fund and investing in a CFD, and CFDs are not available everywhere. They are 2 different class of shares belonging to the same company. Class A shares [par value of 0.01] have 100 voting rights per share. Class B shares [par value of 0.0002] have one voting rights.  Both are listed separately with different ISN and trade at slightly different values. The Class A at higher value than Class B which looks right as it has more voting power. would buying the stock of a REIT qualify as a 'Like-Kind' exchange? Short answer, no. Long answer, a 1031 (Starker) exchange only applies to real estate.  From the Wikipedia page on the topic: To qualify for Section 1031 of the Internal Revenue Code, the properties exchanged must be held for productive use in a trade or business, or for investment. Stocks, bonds, and other properties are listed as expressly excluded by Section 1031 of the Internal Revenue Code, although securitized properties are not excluded. A REIT, being stock in a real estate company, is excluded from Section 1031. Note that your link shows the shares as of March 31, 2016 while http://uniselect.com/content/files/Press-release/Press-Release-Q1-2016-Final.pdf notes a 2-for-1 stock split so thus you have to double the shares to get the proper number is what you are missing. The stock split occurred in May and thus is after the deadline that you quoted. NYSE started allowing four letter tickers around 2009.  NASDAQ allows 4-5 letter tickers.  I guess they'll keep increasing when / if needed.  Companies are allowed to change tickers, although there are costs.  Tickers in the US are assigned through a single entity.  Companies that are new need to take something that's open. http://www.wsj.com/articles/SB124296050986346159 I see that you're in Australia, but, since there aren't really that many options to deal with the problem that you mentioned, I'd guess that you'll ultimately do the same.  Not sure about how tickers are assigned there though.
