Why online brokerages sometimes allow free ETF buying
The same reason a company would offer coupons. I'd guess they're just doing it as a way to entice people to do their investing with them. Since it is any ETF I doubt they are being compensated by the ETF companies, as is sometimes the case (iShares does this with Fidelity, for example). And they still get the commission on the sale.
Interesting, but I don't think we are talking the same thing. This seems to say that that the fund itself doesn't have the rule applied: I.E. the MF can't get hit with the 5% commission when you buy it.  That makes sense.  What I'm asking though is that when my (say) American Fund that I own already does a rebalance, the constituent holdings change. Those securities are not exempt from the rule and thus when they are transacted can have commissions applied.  As a matter of fact the broker for those securities has no idea if the fund is eligible or not.   Where did you get this from? As I'm. It studying for a series 7 I'm probably missing some foundational sources. The creation mechanism for ETF's ensures that the value of the underlying stocks do not diverge significantly from the Fund's value.  Authorized participants have a strong incentive to arbitrage any pricing differences and create/redeem blocks of stock/etf until the prices are back inline.  Contrary to what was stated in a previous answer, this mechanism lowers the cost of management of ETF's when compared to mutual funds that must access the market on a regular basis when any investors enter/exit the fund. The ETF only needs to create/redeem in a wholesale basis, this allows them to operate with management fees that are much lower than those of a mutual fund.  Expenses Due to the passive nature of indexed strategies, the internal   expenses of most ETFs are considerably lower than those of many mutual   funds. Of the more than 900 available ETFs listed on Morningstar in   2010, those with the lowest expense ratios charged about .10%, while   those with the highest expenses ran about 1.25%. By comparison, the   lowest fund fees range from .01% to more than 10% per year for other   funds. (For more on mutual fund feeds, read Stop Paying High Fees.) However, is it a risk that they may withhold liquidity in a market panic crash to protect their own capital?  Two cases exist here. One is if you access the direct market, then they cannot. Secondly if you are trading in the internal market created by them, yes they can do to save their behind, but that is open to question. They don't make money on your profit or loss, their money comes from you trading. So as long as you maintain the required margin in your accounts, you can go ahead. I had a mail exchange with IG Index regarding this and they categorically refuted on this point. Will their clients be unable to sell at a fair market price in a panic crash? No. Also, do CFD providers sometimes make an occasional downward spike to cream off their clients' cut-loss order?  Need proof regarding this, not saying it cannot happen. They wouldn't antagonize the people bringing them business without any reason. They would be putting their money at risk. But you should know, their traders are also in the market. Which might look skimming your money, it would be their traders making money in the free market. After all Google, Facebook etc also sell your personal data for profit, why shouldn't the CFD firm also. Since they are market makers, what is to prevent them from attempting these tricks? Are these concerns also valid for forex brokers serving the retail public? What you consider as tricks are legitimate use of information to make money. "TDAmeritrade, an online stock broker, provides banking services within their brokerage accounts. The service offers all of what you are looking for. HOWEVER, this service is only available for free with their ""Apex"" qualification.  Here is a tariff of their fees and services." One of the often cited advantages of ETFs is that they have a higher   liquidity and that they can be traded at any time during the trading   hours. On the other hand they are often proposed as a simple way to   invest private funds for people that do not want to always keep an eye   on the market, hence the intraday trading is mostly irrelevant for   them. I am pretty sure that this is a subjective idea. The fact is you may buy GOOG, AAPL, F or whatever you wish(ETF as well, such as QQQ, SPY etc.) and keep them for a long time. In both cases, if you do not want to keep an on the market it is ok. Because, if you keep them it is called investment(the idea is collecting dividends etc.), if you are day trading then is it called speculation, because you main goal is to earn by buying and selling, of course you may loose as well. So, you do not care about dividends or owning some percent of the company. As, ETFs are derived instruments, their volatility depends on the volatility of the related shares. I'm wondering whether there are secondary effects that make the   liquidity argument interesting for private investors, despite not   using it themselves. What would these effects be and how do they   impact when compared, for example, to mutual funds? Liquidity(ability to turn cash) could create high volatility which means high risk and high reward. From this point of view mutual funds are more safe. Because, money managers know how to diversify the total portfolio and manage income under any market conditions. I think George's answer explains fairly well why the brokerages don't allow this - it's not an exchange rule, it's just that the brokerage has to have the shares to lend, and normally those shares come from people's margin, which is impossible on a non-marginable stock. To address the question of what the alternatives are, on popular stocks like SIRI, a deep In-The-Money put is a fairly accurate emulation of an actual short interest.  If you look at the options on SIRI you will see that a $3 (or higher) put has a delta of -$1, which is the same delta as an actual short share. You also don't have to worry about problems like margin calls when buying options.  The only thing you have to worry about is the expiration date, which isn't generally a major issue if you're buying in-the-money options... unless you're very wrong about the direction of the stock, in which case you could lose everything, but that's always a risk with penny stocks no matter how you trade them. At least with a put option, the maximum amount you can lose is whatever you spent on the contract.  With a short sale, a bull rush on the stock could potentially wipe out your entire margin.  That's why, when betting on downward motion in a microcap or penny stock, I actually prefer to use options.  Just be aware that option contracts can generally only move in increments of $0.05, and that your brokerage will probably impose a bid-ask spread of up to $0.10, so the share price has to move down at least 10 cents (or 10% on a roughly $1 stock like SIRI) for you to just break even; definitely don't attempt to use this as a day-trading tool and go for longer expirations if you can. I use two different brokerages, both well-known. I got a bit spooked during the financial crisis and didn't want to have all my eggs in one basket. The SIPC limits weren't so much a factor. At the time, I was more worried about the hassle of dealing with a Lehman-style meltdown. If one were to fail, the misery of waiting and filing and dealing with SIPC claims would be mitigated by having half of my money in another brokerage. In hindsight, I was perhaps a bit too paranoid. Dealing with two separate brokerages is not much of an inconvenience, though, and it's interesting to see how their web interfaces are slightly different and some things are easier to do with one vs the other. Overall, they're really similar and I can't say there's much advantage (other than my tin-foil hat tendencies) to splitting it up like that. There is no free ride at most brokers. You will likely be charged a margin fee for that trade even though you only held the margin shares for part of one day. The margin fee would be the annual margin interest rate calculated down to a one day holding period,so it would be smaller. Check your broker's policies but most work like this. "Because ETFs, unlike most other pooled investments, can be easily shorted, it is possible for institutional investors to take an arbitrage position that is long the underlying securities and short the ETF.  The result is that in a well functioning market (where ETF prices are what they should be) these institutional investors would earn a risk-free profit equal to the fee amount. How much is this amount, though? ETFs exist in a very competitive market.  Not only do they compete with each other, but with index and mutual funds and with the possibility of constructing one's own portfolio of the underlying.  ETF investors are very cost-conscious. As a result, ETF fees just barely cover their costs.  Typically, ETF providers do not even do their own trading.  They issue new shares only in exchange for a bundle of the underlying securities, so they have almost no costs.  In order for an institutional investor to make money with the arbitrage you describe, they would need to be able to carry it out for less than the fees earned by the ETF.  Unlike the ETF provider, these investors face borrowing and other shorting costs and limitations. As a result it is not profitable for them to attempt this.  Note that even if they had no costs, their maximum upside would be a few basis points per year.  Lots of low-risk investments do better than that. I'd also like to address your question about what would happen if there was an ETF with exorbitant fees.  Two things about your suggested outcome are incorrect.   If short sellers bid the price down significantly, then the shares would be cheap relative to their stream of future dividends and investors would again buy them.  In a well-functioning market, you can't bid the price of something that clearly is backed by valuable underlying assets down to near zero, as you suggest in your question. Notice that there are limitations to short selling.  The more shares are short-sold, the more difficult it is to locate share to borrow for this purpose.  At first brokers start charging additional fees.  As borrowable shares become harder to find, they require that you obtain a ""locate,"" which takes time and costs money.  Finally they will not allow you to short at all.  Unlimited short selling is not possible. If there was an ETF that charged exorbitant fees, it would fail, but not because of short sellers.  There is an even easier arbitrage strategy: Investors would buy the shares of the ETF (which would be cheaper than the value of the underlying because of the fees) and trade them back to the ETF provider in exchange for shares of the underlying.  This would drain down the underlying asset pool until it was empty.   In fact, it is this mechanism (the ability to trade ETF shares for shares of the underlying and vice versa) that keeps ETF prices fair (within a small tolerance) relative to the underlying indices." The process would look something like:  1. Register your investment company with the SEC 2. Get the ETF approved by the SEC  3. Get a custodian bank (likely requires min assets of a few million) 4. Get listed on an exchange like NYSEARCA by meeting requirements and have an IPO   1 and 2 probably require a lot of time and fees and would be wise to have a lawyer advising, 3 is obviously difficult due to asset requirements and 4 would probably involve an investment bank plus more fees I'm not 100% sure, but I don't think it would be considered a free ride. The idea of a free ride is that you are engaging in a transaction when you do not actually have the money available to cover it, since the broker is technically giving you a 3 day loan whenever you purchase your stock (3 day rule to settle.) However, if you are using a margin account, and you have enough credit available, then you are not actually using unsettled assets, but rather an additional line of credit which was granted to you. You would just need to make sure that your total transactions are less than your purchasing power. That's my take on it anyway. I hope that helps, and hopefully someone can confirm or reject what I have said. ETFs are legally required to publicly disclose their positions at every point in time. The reason for this is that for an ETF to issue shares of ETF they do NOT take cash in exchange but underlying securities - this is called a creation unit. So people need to know which shares to deliver to the fund to get a share of ETF in exchange. This is never done by retail clients, however, but by nominated market makers. Retail persons will normally trade shares only in the secondary market (ie. on a stock exchange), which does not require new shares of the ETF to be issued. However, they do not normally make it easy to find this information in a digestible way, and each ETF does it their own way. So typically services that offer this information are payable (as somebody has to scrape the information from a variety of sources or incentivise ETF providers to send it to them). If you have access to a Bloomberg terminal, this information is available from there. Otherwise there are paid for services that offer it. Searching on Google for ETF constituent data, I found two companies that offer it: See if you can find what you need there. Good luck. (etfdb even has a stock exposure tool freely available that allows you to see which ETFs have large exposure to a stock of your choosing, see here: http://etfdb.com/tool/etf-stock-exposure-tool/). Since this data is in a table format you could easily download it automatically using table parsing tools for your chosen programming language. PS: Don't bother with underlying index constituents, they are NOT required to be made public and index providers will normally charge handsomely for this so normally only institutional investors will have this information. The way it is handled with ETF's is that someone has to gather a block of units and redeem them with the fund. So, with the mutual fund you redeem your unit directly with the fund, always, you never sell to another player. With the ETF - its the opposite, you sell to another player. Once a player has a large chunk of units - he can go to the fund and redeem them. These are very specific players (investment banks), not individual investors. "Yes.  I heard back from a couple brokerages that gave detailed responses. Specifically: In a Margin account, there are no SEC trade settlement rules, which means there is no risk of any free ride violations. The SEC has a FAQ page on free-riding, which states that it applies specifically to cash accounts. This led me to dig up the text on Regulation T which gives the ""free-riding"" rule in §220.8(c), which is titled ""90 day freeze"". §220.8 is the section on cash accounts. Nothing in the sections on margin accounts mentions such a settlement restriction. From the Wikipedia page on Free Riding, the margin agreement implicitly covers settlement. ""Buying Power"" doesn't seem to be a Regulation T thing, but it's something that the brokerages that I've seen use to state how much purchasing power a client has. Given the response from the brokerage, above, and my reading of Regulation T and the relevant Wikipedia page, proceeds from the sale of any security in a margin account are available immediately for reinvestment. Settlement is covered implicitly by margin; i.e. it doesn't detract from buying power. Additionally, I have personally been making these types of trades over the last year. In a sub-$25K margin account, proceeds are immediately available. The only thing I still have to look out for is running into the day-trading rules." It's difficult to compile free information because the large providers are not yet permitted to provide bulk data downloads by their sources.  As better advertising revenue arrangements that mimic youtube become more prevalent, this will assuredly change, based upon the trend. The data is available at money.msn.com.  Here's an example for ASX:TSE.  You can compare that to shares outstanding here. They've been improving the site incrementally over time and have recently added extensive non-US data.  Non-US listings weren't available until about 5 years ago. I haven't used their screener for some years because I've built my own custom tools, but I will tell you that with a little PHP knowledge, you can build a custom screener with just a few pages of code; besides, it wouldn't surprise me if their screener has increased in power.  It may have the filter you seek already conveniently prepared. Based upon the trend, one day bulk data downloads will be available much like how they are for US equities on finviz.com.  To do your part to hasten that wonderful day, I recommend turning off your adblocker on money.msn and clicking on a worthy advertisement.  With enough revenue, a data provider may finally be seduced into entering into better arrangements.  I'd much rather prefer downloading in bulk unadulterated than maintain a custom screener. money.msn has been my go to site for mult-year financials for more than a decade.  They even provide limited 10-year data which also has been expanded slowly over the years.
