What kinds of exchange-traded funds (ETFs) should specifically be avoided?
"Stay away from leveraged or synthetic ETFs. This answer talks about why leveraged ETFs are dangerous. There are numerous articles to be found by searching for ""leveraged etf"". My answer to this question links to one of the more accessible explanations I've read." One of the key things to look for is trading volume.  I think the price spread will be better on high volume ETFs, which means you'll be able to sell for more when the time comes.  Check Google or Yahoo finance for those stats. "As with ANY investment the first answer is....do not invest in any that you do not fully understand.  ETF's are very versatile and can be used for many different people for many different parts of their portfolio, so I don't think there can be a blanket statement of ""this"" one is good or bad for all."
So, couple of things. Firstly, every international ETF includes risk disclosure language in the prospectus covering both market disruption events as well as geopolitical risk, so the sponsor would be pretty well insulated from direct liability for anything. If the Russian market were truly shut down there are true-up mechanisms in place but in the scenario you're describing the market is still open, it's just only a few participants can trade in it.  First thing to do is shut down creates- that is, allow no new money to come into the fund. This at least prevents your problem from getting bigger.   Second you're going to switch all redemptions to in kind only. MV itself can't trade in the underlying so they're kind of jammed here. An ETF sponsor can't really refuse your redemption request (can delay, but only for a short time), but they can control the form in which they respond to it.    What theoretically should happen here is an AP not subject to sanctions will step in and handle redemptions.  Issue is, they'll probably charge for this so you should expect the fund to start trading at a discount to NAV (you, as an investor, sell to them cheaply, they submit a redemption request, then sell the stocks locally). Someone else has pointed that market makers will start stat arbing the fund using correlated/substitute instruments, which totally will help keep things in line, but my guess is that you'd still see the name trading away from NAV regardless. Driver of this will be the amount of money desperate to get out - if investors are content to wait the sanctions out who knows. There are hundreds of entities which offer mutual funds - too many to adequately address here. If you need to pick one, just go with Vanguard for the low low low fees. Yes, this is important. A typical expense ratio of 1% may not sound like much until you realize that the annualized real rate of return on the stock market - after inflation - is about 4%... so the fund eats a quarter of your earnings. (Vanguard's typical expense ratios are closer to 0.1-0.2%). If your company offers a tax-deferred retirement account such as a 401(k), you'll probably find it advantageous to use whatever funds that plan offers just to get the tax advantage, and roll over the account to a cheaper provider when you change employers. You can also buy mutual funds and exchange-traded funds (ETFs) through most brokerages. E*Trade has a nice mutual fund screener, with over 6700 mutual funds and 1180 ETFs. Charles Schwab has one you can browse without even having an account. "As user quid states in his answer, all you need to do is open an account with a stock broker in order to gain access to the world's stock markets.  If you are currently banking with one of the six big bank, then they will offer stockbroking services.  You can shop around for the best commission rates.  If you wish to manage your own investments, then you will open a ""self-directed"" account.  You can shelter your investments from all taxation by opening a TFSA account with your stock broker.  Currently, you can add $5,500 per year to your TFSA.  Unused allowances from previous years can still be used.  Thus, if you have not yet made any TFSA contributions, you can add upto $46,500 to your TFSA and enjoy the benefits of tax free investing. Investing in what you are calling ""unmanaged index funds"" means investing in ETFs (Exchange Traded Funds). Once you have opened your account you can invest in any ETFs traded on the stock markets accessible through your stock broker. Buying shares on foreign markets may carry higher commission rates, but for the US markets commissions are generally the same as they are for Canadian markets.  However, in the case of buying foreign shares you will carry the extra cost and risk of selling Canadian dollars and buying foreign currency.  There are also issues to do with foreign withholding taxes when you trade foreign shares directly.   In the case of the US, you will also need to register with the US tax authorities.  Foreign withholding taxes payable are generally treated as a tax credit with respect to Canadian taxation, so you will not be double taxed. In today's market, for most investors there is generally no need to invest directly in foreign market indices since you can do so indirectly on the Toronto stock market.  The large Canadian ETF providers offer a wide range of US, European, Asian, and Global ETFs as well as Canadian ETFs.  For example, you can track all of the major US indices by trading in Toronto in Canadian dollars.  The S&P500, the Dow Jones, and the NASDAQ100 are offered in both ""currency hedged"" and ""unhedged"" forms.  In addition, there are ETFs on the total US Market, US Small Caps, US sectors such as banks, and more exotic ETFs such as those offering ""covered call"" strategies and ""put write"" strategies. Here is a link to the BMO ETF website. Here is a link to the iShares (Canada) ETF website." This is more than likely a thing about your financial institution and the exchanges where they trade shares. Some exchanges cannot/will not handle odd lot transactions. Most established brokerages have software and accounting systems that will deal in round lots with the exchanges, but can track your shares individually. Sometimes specific stocks cannot be purchased in odd lots due to circumstances specific to that stock (trading only on a specific exchange, for example).  Most brokerages offer dollar-cost averaging programs, but may limit which stocks are eligible, due to odd lot and partial share purchases. Check with your brokerage to see if they can support odd lot and/or DCA purchases. You may find another similar ETF with similar holdings that has better trading conditions, or might consider an open-end mutual fund with similar objectives. Mutual funds allow partial share purchases (you have $100 to invest today, and they issue you 35.2 shares, for example). If you're a person of normal means, being a short-term trader/speculator is a game that you are going to lose. Don't do it -- do some research on investing. Thanks for the huge insight. I am still a student doing an intern and this was given as my first task, more of trying to give the IA another perspective looking at these funds rather than picking. I was not given the investors preference in terms of return and risk tolerances so it was really open-ended.   However, thanks so much for the quick response. At least now I have a better idea of what I am going to deliver or at least try to show to the IA. "Here's an example that I'm trying to figure out.  ETF firm has an agreement with GS for blocks of IBM. They have agreed on daily VWAP + 1% for execution price.  Further, there is a commission schedule for 5 mils with GS.  Come month end, ETF firm has to do a monthly rebalance. As such must buy 100,000 shares at IBM which goes for about $100  The commission for the trade is 100,000 * 5 mils = $500 in commission for that trade. I assume all of this is covered in the expense ratio. Such that if VWAP for the day was 100, then each share got executed to the ETF at 101 (VWAP+ %1) + .0005 (5 mils per share) = for a resultant 101.0005 cost basis  The ETF then turns around and takes out (let's say) 1% as the expense ratio ($1.01005 per share)  I think everything so far is pretty straight forward. Let me know if I missed something to this point.  Now, this is what I'm trying to get my head around. ETF firm has a revenue sharing agreement as well as other ""relations"" with GS. One of which is 50% back on commissions as soft dollars. On top of that GS has a program where if you do a set amount of ""VWAP +"" trades you are eligible for their corporate well-being programs and other ""sponsorship"" of ETF's interests including helping to pay for marketing, rent, computers, etc.   Does that happen? Do these disclosures exist somewhere?" I'm not a professional, but my understanding is that US funds are not considered PFICs regardless of the fact that they are held in a foreign brokerage account. In addition, be aware that foreign stocks are not considered PFICs (although foreign ETFs may be).
