Buying an ETF vs. The explicit Index
what reason would I have in buying an ETF? Apart from the efforts, the real reason is the ticket size. One can't buy shares in fraction. To truly reflect the index in equal weight, the amount to invest will be in multiples of millions [depending on the Index and the stock composition]   This related question should help you understand why it is difficult even for large fund house to exactly mimic the index. Why do passive ETFs require so much trading (and incur costs)? To add to Dheer's point, the vast majority of retail investors will have to pay fees and use up a large amount of valuable time on the entrance and exit of each stock, and each and every time you rebalance as the index weightings change. These also add up extremely fast vs the few basis points the large and liquid ETFs charge for this service.
"According to what little information is available currently, this fund is most akin to an actively managed exchange traded fund rather than an investment trust. An investment trust is an actively managed, closed-end fund that is tradeable on the stock market.  ""Closed-end"" means that there are a fixed number of shares available for trading, so if you wish to buy or sell shares in a closed-end fund you need to find someone willing to sell or buy shares.  ""Actively managed"" means that the assets are selected by the fund managers in the belief that they will perform well.  This is in contrast to a ""passively managed"" fund which simply tracks an underlying index.   The closed-end nature of investment trusts means that the share price is not well correlated to the value of the underlying assets.  Indeed, almost all UK investment trusts trade at a significant discount to their net asset value.  This reflects their historic poor performance and relatively weak liquidity.  Of course there are some exceptions to this. Examples of open-end funds are unit trust (US = mutual funds) and ETFs (exchange traded funds).  They are ""open-end"" funds in the sense that the number of shares/units available will change according to demand.  Most importantly, the price of a share/unit will be strongly correlated to the net asset value of the underlying portfolio.  In general, for an open-end fund, if the net asset value of the fund is X and there are Y shares/units outstanding, then the price of a share/unit will be X/Y.  Historic data shows that passively managed funds (index trackers) ""always"" outperform actively managed funds in the long term.  One of the big issues with actively managed funds is they have relatively high management fees.  The Peoples Trust will be charging about 1% with a promise that this should come down over time.  Compare this to a fee of 0.05% on a large, major market index tracking ETF.  Further, the 1% headline fee being touted by Peoples Trust is a somewhat misleading, since they are paying their employees bonuses with shares in the fund.  This will cause dilution of the net asset value per share and can be read as addition management fees by proxy.  Since competent fund managers will demand high incomes, bonus shares could easily double the management fees, depending on the size of the fund. In summary, history has shown that the promises of active fund managers rarely (if ever) come to fruition. Personally, I would not consider this to be an attractive investment and would look more towards a passively managed major market index ETF with low management fees." Use a currency ETF.  there are many.  Specific to your question there is WisdomTree Dreyfus Brazilian Real Fund (BZF) I don't happen to find a currency ETF for Thailand, so the closest you could come to a Thai currency fund would be something that's an Index fund ETF that is based on an index in the Thai Market such as:  MSCI Thailand Investable Market Index Fund Because that fund is investing in an index of stocks that trade on the Thai market, you are in effect investing in something denominated in Baht.  This is spelled out in the prospectus where it discusses 'currency risk'.   The problem is that you are however not investing in just the currency, but rather a broad index of stocks denominated in that currency.  Still to the extent the market holds fairly steady, you get much the same effect of investing in just the currency.  to the extent the market is moving, you get the net effect of what the thai market does, plus how the bhat trades relative to the dollar. "I wonder if ETF's are further removed from the actual underlying holdings or assets giving value to the fund, as compared to regular mutual funds. Not exactly removed. But slightly different. Whenever a Fund want to launch an ETF, it would buy the underlying shares; create units. Lets say it purchased 10 of A, 20 of B and 25 of C. And created 100 units for price x. As part of listing, the ETF company will keep the purchased shares of A,B,C with a custodian. Only then it is allowed to sell the 100 units into the market. Once created, units are bought or sold like regular stock. In case the demand is huge, more units are created and the underlying shares kept with custodian.  So, for instance, would VTI and Total Stock Market Index Admiral Shares be equally anchored to the underlying shares of the companies within the index? Yes they are. Are they both connected? Yes to an extent. The way Vanguard is managing this is given a Index [Investment Objective]; it is further splitting the common set of assets into different class. Read more at Share Class. The Portfolio & Management gives out the assets per share class. So Vanguard Total Stock Market Index is a common pool that has VTI ETF, Admiral and Investor Share and possibly Institutional share. Is VTI more of a ""derivative""? No it is not a derivative. It is a Mutual Fund." ACWI refers to a fund that tracks the MSCI All Country World Index, which is  A market capitalization weighted index designed to provide a broad measure of equity-market performance throughout the world. The MSCI ACWI is maintained by Morgan Stanley Capital International, and is comprised of stocks from both developed and emerging markets.  The ex-US in the name implies exactly what it sounds; this fund probably invests in stock markets (or stock market indexes) of the countries in the index, except the US. Brd Mkt refers to a Broad Market index, which, in the US, means that the fund attempts to track the performance of a wide swath of the US stock market (wider than just the S&P 500, for example). The Dow Jones U.S. Total Stock Market Index, the Wilshire 5000 index, the Russell 2000 index, the MSCI US Broad Market Index, and the CRSP US Total Market Index are all examples of such an index. This could also refer to a fund similar to the one above in that it tracks a broad swath of the several stock markets across the world. I spoke with BNY Mellon about the rest, and they told me this: EB - Employee Benefit (a bank collective fund for ERISA qualified assets) DL - Daily Liquid (provides for daily trading of fund shares) SL - Securities Lending (fund engages in the BNY Mellon securities lending program) Non-SL - Non-Securities Lending (fund does not engage in the BNY Mellon securities lending program) I'll add more detail. EB (Employee Benefit) refers to plans that fall under the Employee Retirement Income Security Act, which are a set a laws that govern employee pensions and retirement plans. This is simply BNY Mellon's designation for funds that are offered through 401(k)'s and other retirement vehicles. As I said before, DL refers to Daily Liquidity, which means that you can buy into and sell out of the fund on a daily basis. There may be fees for this in your plan, however. SL (Securities Lending) often refers to institutional funds that loan out their long positions to investment banks or brokers so that the clients of those banks/brokerages can sell the shares short. This SeekingAlpha article has a good explanation of how this procedure works in practice for ETF's, and the procedure is identical for mutual funds: An exchange-traded fund lends out shares of its holdings to another party and charges a rental fee. Running a securities-lending program is another way for an ETF provider to wring more return out of a fund's holdings. Revenue from these programs is used to offset a fund's expenses, which allows the provider to charge a lower expense ratio and/or tighten the performance gap between an ETF and its benchmark. "Back in the olden days, if you wanted to buy the S&P, you had to have a lot of money so you can buy the shares. Then somebody had the bright idea of making a fund that just buys the S&P, and then sells small pieces of it to investor without huge mountains of capital. Enter the ETFs. The guy running the ETF, of course, doesn't do it for free. He skims a little bit of money off the top. This is the ""fee"". The major S&P ETFs all have tiny fees, in the percents of a percent. If you're buying the index, you're probably looking at gains (or losses) to the tune of 5, 10, 20% - unless you're doing something really silly, you wouldn't even notice the fee. As often happens, when one guy starts doing something and making money, there will immediately be copycats. So now we have competing ETFs all providing the same service. You are technically a competitor as well, since you could compete with all these funds by just buying a basket of shares yourself, thereby running your own private fund for yourself. The reason this stuff even started was that people said, ""well why bother with mutual funds when they charge such huge fees and still don't beat the index anyway"", so the index ETFs are supposed to be a low cost alternative to mutual funds. Thus one thing ETFs compete on is fees: You can see how VOO has lower fees than SPY and IVV, in keeping with Vanguard's philosophy of minimal management (and management fees). Incidentally, if you buy the shares directly, you wouldn't charge yourself fees, but you would have to pay commissions on each stock and it would destroy you - another benefit of the ETFs. Moreover, these ETFs claim they track the index, but of course there is no real way to peg an asset to another. So they ensure tracking by keeping a carefully curated portfolio. Of course nobody is perfect, and there's tracking error. You can in theory compare the ETFs in this respect and buy the one with the least tracking error. However they all basically track very closely, again the error is fractions of the percent, if it is a legitimate concern in your books then you're not doing index investing right. The actual prices of each fund may vary, but the price hardly matters - the key metric is does it go up 20% when the index goes up 20%? And they all do. So what do you compare them on? Well, typically companies offer people perks to attract them to their own product. If you are a Fidelity customer, and you buy IVV, they will waive your commission if you hold it for a month. I believe Vanguard will also sell VOO for free. But for instance Fidelity will take commission from VOO trades and vice versa. So, this would be your main factor. Though, then again, you can just make an account on Robinhood and they're all commission free. A second factor is reliability of the operator. Frankly, I doubt any of these operators are at all untrustworthy, and you'd be buying your own broker's ETF anyway, and presumably you already went with the most trustworthy broker. Besides that, like I said, there's trivial matters like fees and tracking error, but you might as well just flip a coin. It doesn't really matter." On the US markets, most index options are European style.  Most stock and ETF options are, as you noted, American style. "As Dheer pointed out, the top ten mega-cap corporations account for a huge part (20%) of your ""S&P 500"" portfolio when weighted proportionally. This is one of the reasons why I have personally avoided the index-fund/etf craze -- I don't really need another mechanism to buy ExxonMobil, IBM and Wal-Mart on my behalf. I like the equal-weight concept -- if I'm investing in a broad sector (Large Cap companies), I want diversification across the entire sector and avoid concentration. The downside to this approach is that there will be more portfolio turnover (and expense), since you're holding more shares of the lower tranches of the index where companies are more apt to churn. (ie. #500 on the index gets replaced by an up and comer). So you're likely to have a higher expense ratio, which matters to many folks." But if you add a security to the index you also remove one from the index, thus both a buy and sell. If weights change some go up, some go down thus some need to be purchased and some need to be sold.   So I still don't see how ETFs are net sinks beyond their simple AUM.
