Should a retail trader choose a broker with access to dark pools
"That's like a car dealer advertising their ""huge access"" to Chevrolet.  All brokers utilize dark pools nowadays, either their own or one belonging to a larger financial institution.  Why?  Because that's a primary source of broker income.  Example: Under current US regulations the broker is under no obligation to pass these orders to actual (a.k.a. lit) exchanges.  Instead it can internalize them in its dark pool as long as it ""improves the price"".  So: If a broker doesn't run its own dark pool, then it sends the orders to the dark pool run by a larger institution (JPMorgan, Credit Suisse, Getco, Knight Capital) and gets some fraction of the dark pool's profit in return. Are Mom and Pop negatively impacted by this?  Not for most order types.  They each even got a free penny out of the deal!  But if there were no dark pools, that $1.00 difference between their trade prices would have gone half ($0.50) to Mom's counterparty and half ($0.50) to Pop's counterparty, who could be someone else's Mom and someone else's Pop. So ... that's why brokers all use dark pools, and why their advertisement of their dark pool access is silly.  They're basically saying, ""We're going to occasionally throw you a free penny while making 49 times that much from you""! (Note: Now apply the above math to a less liquid product than AAPL.  Say, where the spread is not $0.01, but more like $0.05.  Now Mom and Pop still might make a penny each, while the broker can make $4.98 on a 100 share trade!)"
For question #1, at least some US-based online brokers do permit direct purchases of stocks on foreign exchanges. Depending on your circumstances, this might be more cost effective than purchasing US-listed ADRs. One such broker is Interactive Brokers, which allows US citizens to directly purchase shares on many different foreign exchanges using their online platform (including in France). For France, I believe their costs are currently 0.1% of the total trade value with a 4€ minimum. I should warn you that the IB platform is not particularly user-friendly, since they market themselves to traders and the learning curve is steep (although accounts are available to individual investors). IB also won't automatically convert currencies for you, so you also need to use their foreign exchange trading interface to acquire the foreign currency used to purchase a foreign stock, which has plusses and minuses. On the plus side, their F/X spread is very competitive, but the interface is, shall we say, not very intuitive. I can't answer question #2 with specific regards to US/France. At least in the case of IB, though, I believe any dividends from a EUR-denominated stock would continue to accumulate in your account in Euros until you decide to convert them to dollars (or you could reinvest in EUR if you so choose). "If you're investing for the long term your best strategy is going to be a buy-and-hold strategy, or even just buying a few index funds in several major asset classes and forgetting about it. Following ""market conditions"" is about as useful to the long term trader as checking the weather in Anchorage, Alaska every day (assuming that you don't live in Anchorage, Alaska). Let me suggest treating yourself to a subscription to The Economist and read it once a week. You'll learn a lot more about investing, economics, and world trends, and you won't be completely in the dark if there are major structural changes in the world (like gigantic housing bubbles) that you might want to know about." "Pay to play? You mean they pay for beefier data feeds that other firms don't need, sure they do. But everyone can trade on the US exchanges now (NYSE, NASDAQ, BATS, etc) which was not true 20 years ago when NYSE had the specialist monopoly, so yes the markets are more democratic than they've ever been.  Side note, the exchanges do directly profit from increased trading volume because they take a small % of every trade, so I'm not sure what you mean they don't directly profit from it.  Also I get the feeling you don't understand the scope of HFT activity, HFT peak profits were on the order of 7 billion during the highest volume time of the last decade (2005-2010). They are now around 1B. Compared to the trillions of dollars that change hands in the exchange per year, this is chump change, hardly a ""free money faucet"".  Also Katsayuma opened yet another dark pool that caters to high volume clients (your goldmans and merrils). The only difference in IEX is it got a free marketing campaign to entice clients. Seriously, IEX is nothing more than the existing fixed cross dark pools, which btw screws over retail investors more than the lit exchanges like NASDAQ.   Katsayuma got steamrolled in his executions because he couldn't keep up with the time and then hit the lottery jackpot by getting Michael Lewis to paint him as a ""hero"", honestly I'm confounded at how lucky that dude got.  BTW broker dealers get preferential treatment in IEX, meaning they get to cut in front of the line in front of retail investors. Why are you so opinionated about this, did you make a few bad trades on eTrade and need a scapegoat?" "Generally, yes.  Rather than ask, ""why are these guys so cheap?"", you should be asking why the big names are so expensive. :) Marketing spend plays a big role there. Getting babies to shill for your company during the super bowl requires a heck of a lot of commissions. Due to the difficulties involved in setting up a brokerage, it's unlikely that you'll see a scam. A brokerage might go bankrupt for random reasons, but that's what investor insurance is for. ""Safeness"" is mostly the likelihood that you'll be able to get access to your funds on deposit with the broker. Investment funds are insured by SIPC for up to $500,000, with a lower limit on cash. The specific limits vary by broker, with some offering greater protection paid for on their own dime. Check with the broker -- it's usually on their web pages under ""Security"". Funds in ""cash"" might be swept into an interest-earning investment vehicle for which insurance is different, and that depends on the broker, too. A few Forex brokers went bankrupt last year, although that's a new market with fewer regulatory protections for traders. I heard that one bankruptcy in the space resulted in a 7% loss for traders with accounts there, and that there was a Ponzi-ish scam company as well. Luckily, the more stringent regulation of stock brokerages makes that space much safer for investors. If you want to assess the reliability of an online broker, I suggest the following: It's tempting to look at when the brokerage was founded. Fly-by-night scams, by definition, won't be around very long -- and usually that means under a few months. Any company with a significant online interface will have to have been around long enough to develop that client interface, their backend databases, and the interface with the markets and their clearing house. The two brokerages you mentioned have been around for 7+ years, so that lends strength to the supposition of a strong business model. That said, there could well be a new company that offers services or prices that fit your investment need, and in that case definitely look into their registrations and third-party reviews. Finally, note that the smaller, independent brokerages will probably have stiffer margin rules. If you're playing a complex, novel, and/or high-risk strategy that can't handle the volatility of a market crash, even a short excursion such as the 2010 flash crash, stiff margin rules might have consequences that a novice investor would rather pretend didn't exist." "Lending of shares happens in the background. Those who have lent them out are not aware that they have been lent out, nor when they are returned. The borrowers have to pay any dividends to the lenders and in the end the borrowers get their stock back. If you read the fine print on the account agreement for a margin account, you will see that you have given the brokerage the permission to silently loan your stocks out.  Since the lending has no financial impact on your portfolio, there's no particular reason to know and no particular protection required.  Actually, brokers typically don't bother going through the work of finding an actual stock to borrow.  As long as lots of their customers have stocks to lend and not that many people have sold short, they just assume there is no problem and keep track of how many are long and short without designating which stocks are borrowed from whom. When a stock becomes hard to borrow because of liquidity issues or because many people are shorting it, the brokerage will actually start locating individual shares to borrow, which is a more time-consuming and costly procedure.  Usually this involves the short seller actually talking to the broker on the phone rather than just clicking ""sell.""" While you are correct that no broker-dealer ever qualifies for FDIC and it could be sufficient for customers to know that general rule, for broker-dealers located at or 'networked' with a bank -- and nowadays many probably most are -- these explicit statements that non-bank investments are not guaranteed by the bank or FDIC and may lose principal (often stated as 'may lose value') are REQUIRED; see http://finra.complinet.com/en/display/display_main.html?rbid=2403&element_id=9093 . The key two things to consider when looking at similar/identical ETFs is the typical (or 'indicative') spread, and the trading volume and size of the ETF. Just like regular stocks, thinly traded ETF's often have quite large spreads between buy and sell: in the 1.5-2%+ range in some cases. This is a huge drain if you make a lot of transactions and can easily be a much larger concern than a relatively trivial difference in ongoing charges depending on your exact expected trading frequency. Poor spreads are also generally related to a lack of liquidity, and illiquid assets are usually the first to become heavily disconnected from the underlying in cases where the authorized participants (APs) face issues. In general with stock ETFs that trade very liquid markets this has historically not been much of an issue, as the creation/redemption mechanism on these types of assets is pretty robust: it's consequences on typical spread is much more important for the average retail investor. On point #3, no, this would create an arbitrage which an authorized participant would quickly take advantage of. Worth reading up about the creation and redemption mechanism (here is a good place to start) to understand the exact way this happens in ETFs as it's very key to how they work. That's up to you. If you instruct your broker to sell shares purchased in specific lots, they can do that -- but doing so requires that you and/or they track specific fractional lots forever afterwards so you know what is still there to be sold. FIFO simplifies the bookkeeping. And I am not convinced selecting specific lots makes much difference; the government gets its share of your profits sooner or later.
