When looking at a mutual fund, how can you tell if it is a traditional fund or an ETF?
"An Exchange-Traded Fund (ETF) is a special type of mutual fund that is traded on the stock exchange like a stock.  To invest, you buy it through a stock broker, just as you would if you were buying an individual stock. When looking at a mutual fund based in the U.S., the easiest way to tell whether or not it is an ETF is by looking at the ticker symbol.  Traditional mutual funds have ticker symbols that end in ""X"", and ETFs have ticker symbols that do not end in ""X"".   The JPMorgan Emerging Markets Equity Fund, with ticker symbol JFAMX, is a traditional mutual fund, not an ETF.  JPMorgan does have ETFs; the JPMorgan Diversified Return Emerging Markets Equity ETF, with ticker symbol JPEM, is an example.  This ETF invests in similar stocks as JFAMX; however, because it is an index-based fund instead of an actively managed fund, it has lower fees. If you aren't sure about the ticker symbol, the advertising/prospectus of any ETF should clearly state that it is an ETF.  (In the example of JPEM above, they put ""ETF"" right in the fund name.)  If you don't see ETF mentioned, it is most likely a traditional mutual fund. Another way to tell is by looking at the ""investment minimums"" of the fund.  JFAMX has a minimum initial investment of $1000.  ETFs, however, do not have an investment minimum listed; because it is traded like a stock, you simply buy whole shares at whatever the current share price is.  So if you look at the ""Fees and Investment Minimums"" section of the JPEM page, you'll see the fees listed, but not any investment minimums."
If you have just started an IRA (presumably with a contribution for 2012),  you likely have $5000 in it, or $10,000 if you made a full contribution for  2013 as well. At this time, I would recommend putting it all in a  single low-cost mutual fund. Typically, mutual funds that track an index such as the S&P 500 Index have lower costs (annual expense fees) than actively managed funds, and most investment companies offer such mutual funds, with Fidelity, Vanguard, Schwab, to name a few, having very low expenses even among index funds. Later, when you have more money in the account, you can consider diversifying into more funds, buying stocks and bonds, investing in ETFs, etc. Incidentally, if you are just starting out and your Roth IRA is essentially your first investment experience, be aware that you do not need a brokerage account for your Roth IRA until you have more money in the account to invest and specifically want to buy individual stocks and bonds instead of just mutual funds. If you opened a brokerage account for your Roth IRA, close it and  transfer the Roth IRA to your choice of mutual fund company; else you will be paying annual fees to the brokerage for maintaining your account, inactivity fees since you won't be doing any trading, etc. The easiest way to do this is to go to the mutual fund company web site and tell them that you want to transfer your IRA to them (not roll over your IRA to them) and they will take care of all the paper work and collecting your money from the brokerage (ditto if your Roth IRA is with a bank or another mutual fund company). Then close your brokerage account. Mutual funds buy (and sell) shares in companies in accordance with  the policies set forth in their prospectus, not according to the  individual needs of an investor, that is, when you invest money in (or withdraw money from) a mutual fund,  the manager buys or sells whatever shares that, in the manager's judgement,  will be the most appropriate ones (consistent with the investment policies). Thus, a large-cap mutual fund manager will not buy the latest hot small-cap stock that will likely be hugely profitable; he/she must choose only between various large capitalization companies. Some exchange-traded funds are fixed baskets of stocks. Suppose you will not invest in a company X as a matter of principle. Unless a mutual fund prospectus says that it will not invest in X, you may well end up having an investment in X at some time because the fund manager bought shares in X. With such an ETF,  you know what is in the basket, and if the basket does not include stock in X  now, it will not own stock in X at a later date. Some exchange-traded funds are constructed based on some index and track the index as a matter of policy. Thus, you will not be investing in X unless X becomes part of the index because Standard or Poor or Russell or somebody changed their minds, and the ETF buys X in order to track the index. Finally, some ETFs are exactly like general mutual funds except that you can buy or sell ETF shares at any time at the price at the instant that your order is executed whereas with mutual funds, the price of the mutual fund shares that you have bought or sold is the NAV of the mutual fund shares for that day, which is established based on the closing prices at the end of the trading day of the stocks, bonds etc that the fund owns.  So, you might end up owning stock in X at any time based on what the fund manager thinks about X. "401(k) doesn't have a ""return rate"", because 401(k) is not a type of investment -- it is a vehicle for investment, with certain tax treatments. Just like your money that's not in a 401(k), you can invest it in either the bank, a CD, stocks, mutual funds, bonds, etc., you can similarly (depending on the options given to you by your 401(k) plan) invest the money in the 401(k) in a cash account, buy stocks, mutual funds, etc. Your return is dependent on how you invest your money, not whether it's in a 401(k) or not. Whether it's in a (Roth or Traditional) 401(k) simply affects when and how it gets taxed. (It is true that most 401(k) plans offer little variety in types of investments you can choose; however, this is not a big deal, as chances are that in a few years, you will leave your company, at which point you are able to rollover the 401(k) into an IRA, at which point you will have many, many options for how to invest it.) To make a valid comparison, you should be comparing the same type of investment in both cases. That means, you should assume the same return for both the money outside the 401(k), and the money inside the 401(k), and only consider the taxes and penalties (if you plan to withdraw early)." Behind the scenes, mutual funds and ETFs are very similar.  Both can vary widely in purpose and policies, which is why understanding the prospectus before investing is so important. Since both mutual funds and ETFs cover a wide range of choices, any discussion of management, assets, or expenses when discussing the differences between the two is inaccurate.  Mutual funds and ETFs can both be either managed or index-based,  high expense or low expense, stock or commodity backed. Method of investing When you invest in a mutual fund, you typically set up an account with the mutual fund company and send your money directly to them.  There is often a minimum initial investment required to open your mutual fund account.  Mutual funds sometimes, but not always, have a load, which is a fee that you pay either when you put money in or take money out. An ETF is a mutual fund that is traded like a stock.  To invest, you need a brokerage account that can buy and sell stocks.  When you invest, you pay a transaction fee, just as you would if you purchase a stock.  There isn't really a minimum investment required as there is with a traditional mutual fund, but you usually need to purchase whole shares of the ETF.  There is inherently no load with ETFs. Tax treatment Mutual funds and ETFs are usually taxed the same.  However, capital gain distributions, which are taxable events that occur while you are holding the investment, are more common with mutual funds than they are with ETFs, due to the way that ETFs are structured.  (See Fidelity: ETF versus mutual funds: Tax efficiency for more details.)  That having been said, in an index fund, capital gain distributions are rare anyway, due to the low turnover of the fund. Conclusion When comparing a mutual fund and ETF with similar objectives and expenses and deciding which to choose, it more often comes down to convenience.  If you already have a brokerage account and you are planning on making a one-time investment, an ETF could be more convenient.  If, on the other hand, you have more than the minimum initial investment required and you also plan on making additional regular monthly investments, a traditional no-load mutual fund account could be more convenient and less expensive. "Does the bolded sentence apply for ETFs and ETF companies? No, the value of an ETF is determined by an exchange and thus the value of the share is whatever the trading price is. Thus, the price of an ETF may go up or down just like other securities. Money market funds can be a bit different as the mutual fund company will typically step in to avoid ""Breaking the Buck"" that could happen as a failure for that kind of fund. To wit,   must ETF companies invest a dollar in the ETF for every dollar that an   investor deposited in this aforesaid ETF? No, because an ETF is traded as shares on the market, unless you are using the creation/redemption mechanism for the ETF, you are buying and selling shares like most retail investors I'd suspect. If you are using the creation/redemption system then there are baskets of other securities that are being swapped either for shares in the ETF or from shares in the ETF." Index Funds & ETFs, if they are tracking the same index, will be the same in an ideal world. The difference would be because of the following factors: Expense ratio: i.e. the expense the funds charge. This varies and hence it would lead to a difference in performance. Tracking error: this means that there is a small percentage of error between the actual index composition and the fund composition. This is due to various reasons.  Effectively this would result in the difference between values. Demand / Supply: with ETFs, the fund is traded on stock exchanges like a stock. If the general feeling is that the index is rising, it could lead to an increase in the price of the ETF. Index funds on the other hand would remain the same for the day and are less liquid. This results in a price increase / decrease depending on the market. The above explains the reason for the difference.   Regarding which one to buy, one would need to consider other factors like: a) How easy is it to buy ETFs? Do you already hold Demat A/C & access to brokers to help you conduct the transaction or do you need to open an additional account at some cost. b) Normally funds do not need any account, but are you OK with less liquidity as it would take more time to redeem funds. What decision are you trying to make?  Are you interested day trading stocks to make it rich? Or are you looking at your investment options and trying to decide between an actively managed mutual fund and an ETF? If the former, then precise statistics are hard to come by, but I believe that 99% of day traders would do better investing in an ETF. If the latter, then there are lots of studies that show that most actively managed funds do worse than index funds, so with most actively managed funds you are paying higher fees for worse performance.  Here is a quote from the Bogleheads Guide to Investing: Index funds outperform approximately 80 percent of all actively   managed funds over long periods of time. They do so for one simple   reason: rock-bottom costs. In a random market, we don't know what   future returns will be. However, we do know that an investor who keeps   his or her costs low will earn a higher return than one who does not.   That's the indexer's edge. Many people believe that your best option for investing is a diverse portfolio of ETFs, like this.  This is what I do.
