Can I use same stock broker to buy stocks from different stock markets?
"In the US there is only one stock market (ignoring penny stocks) and handfuls of different exchanges behind it.  NYSE and NASDAQ are two different exchanges, but all the products you can buy on one can also be bought on the other; i.e. they are all the same market.  So a US equities broker cannot possibly restrict access to any ""markets"" in the US because there is only one. (Interestingly, it is commonplace for US equity brokers to cheat their customers by using only exchanges where they -- the brokers -- get the best deals, even if it means your order is not executed as quickly or cheaply as possible.  This is called payment for order flow and unfortunately will probably take an Act of Congress to stop.) Some very large brokers will have trading access to popular equity markets in other countries (Toronto Stock Exchange, Mexico Stock Exchange, London Stock Exchange) and can support your trades there.  However, at many brokers or in less popular foreign markets this is usually not the case; to trade in the average foreign country you typically must open an account with a broker in that country." "Most stock brokers are ""full service"" brokers. That is to say that you can so the same broker to buy different types of stocks, bonds, options, etc. in different markets. Some brokers are very specialized and won't allow you to do that. But those are probably brokers you don't want to use."
"Good question! It seems to me that there is no minimum order size for shares trading on the LSE. Please note, I couldn't find an definite answer, but: According to the ""International Order Book"" document (see: http://www.londonstockexchange.com/traders-and-brokers/rules-regulations/change-and-updates/stock-exchange-notices/2010/n2210_attach1.pdf) from the LSE (page 7): Question 7: Would respondents support a revision of the minimum order    size of 50 units?   Whilst there was   limited support for a low value based   minimum order size the  majority of   respondents requested its complete   removal.  This was  incorporated into   the September 2010 quarterly review as   per Service  Announcement 001/100910   and as from 20 September 2010, the   minimum  order size in all IOB   securities has been 1 unit Even though not all trading on the LSE is performed on this IOB system, it would be very wierd if the international stocks can be traded in any size, while domestic stocks will have an minimum size. Further, consider looking to the times and sales of various stocks (here you can find an example http://www.londonstockexchange.com/exchange/prices-and-markets/stocks/exchange-insight/trade-data.html?page=0&fourWayKey=GB0006731235GBGBXSET1&formName=frmRow&upToRow=-1). Those trades also suggest that there is no minimum order size (for example, I just saw an executed trade with an size of 13). At last, look at the Interactive Brokers (no relationship with) Exchange List at http://www.interactivebrokers.com/en/trading/exchanges.php?exch=lse&showcategories=&ib_entity=llc. Here you can click on various stock names, and in the popup window that opens, look for 'size parameters' and the size increment. I could only find stocks with an size increment of 1 (i.e. you can trade anything with a minimum of 1 stock, and more needs to be in steps of 1 stock). Even though I couldn't find official information on the LSE site (like a leaflet for beginners or such), it does seem to me that you can trade any size you want on LSE.  Please note that mutual funds and illiquid OTC stocks which don't have an continuous market can have different rules, so double-check with your broker." Depending on your broker, you can buy these stocks directly at the most liquid local exchanges. For instance, if you are US resident and want to to buy German stocks (like RWE) you can trade these stocks over InteractiveBrokers (or other direct brokers in the US). They offer direct access to German Xetra and other local markets. "Most of the investors who have large holdings in a particular stock have pretty good exit strategies for those positions to ensure they are getting the best price they can by selling gradually into the volume over time. Putting a single large block of stock up for sale is problematic for one simple reason: Let's say you have 100,000 shares of a stock, and for some reason you decide today is the day to sell them, take your profits, and ride off into the sunset.  So you call your broker (or log into your brokerage account) and put them up for sale.  He puts in an order somewhere, the stock is sold, and your account is credited. Seems simple, right?  Well...not so fast. Professionals - I'm keeping this simple, so please don't beat me up for it! The way stocks are bought and sold is through companies known as ""market makers"".  These are entities which sit between the markets and you (and your broker), and when you want to buy or sell a stock, most of the time the order is ultimately handled somewhere along the line by a market maker.  If you work with a large brokerage firm, sometimes they'll buy or sell your shares out of their own accounts, but that's another story. It is normal for there to be many, sometimes hundreds, of market makers who are all trading in the same equity.  The bigger the stock, the more market makers it attracts.  They all compete with each other for business, and they make their money on the spread between what they buy stock from people selling for and what they can get for it selling it to people who want it. Given that there could be hundreds of market makers on a particular stock (Google, Apple, and Microsoft are good examples of having hundreds of market makers trading in their stocks), it is very competitive.  The way the makers compete is on price.  It might surprise you to know that it is the market makers, not the markets, that decide what a stock will buy or sell for. Each market maker sets their own prices for what they'll pay to buy from sellers for, and what they'll sell it to buyers for.  This is called, respectively, the ""bid"" and the ""ask"" prices.  So, if there are hundreds of market makers then there could be hundreds of different bid and ask prices on the same stock.  The prices you see for stocks are what are called the ""best bid and best ask"" prices.  What that means is, you are being shown the highest ""bid"" price (what you can sell your shares for) and the best ""ask"" price (what you can buy those shares for) because that's what is required.  That being said, there are many other market makers on the same stock whose bid prices are lower and ask prices are higher.  Many times there will be a big clump of market makers all at the same bid/ask, or within fractions of a cent of each other, all competing for business.  Trading computers are taught to seek out the best prices and the fastest trade fills they can. The point to this very simplistic lesson is that the market makers set the prices that shares trade at.  They adjust those prices based (among other factors) on how much buying and selling volume they're seeing.  If they see a wave of sell orders coming into the system then they'll start marking down their bid prices.  This keeps them from paying too much for shares they're going to have to find a buyer for eventually, and it can sometimes slow down the pace of selling as investors and automated systems notice the price decline and decide to wait to sell.  Conversely, if market makers see a wave of buy orders coming into the system, they'll start marking their ask prices up to maximize their gains, since they're selling you shares they bought from someone else, presumably at a lower price.  But they typically adjust their prices up or down before they actually fill trades.  (sneaky, eh?) Depending on how much volume there is on the shares of the company you're selling, and depending on whether there are more buyers than sellers at the moment, your share sell order may be filled at market by a market maker with no real consequence to the share's price. If the block is large enough then it's possible it will not all sell to one market maker, or it might not all happen in one transaction or even all at the same price. This is a pretty complex subject, as you can see, and I've cut a LOT of corners and oversimplified much to keep it comprehensible.  But the short answer to your question is -- it depends. Hope this helps. Good luck!" It's important to distinguish between speculation and investing. Buying something because you hope to make money on market fluctuations is speculation. Buying something and expecting to make money because your money is providing actual economic value is investing.  If Person A buys 100 shares of a stock with the intent of selling them in a few hours, and Person B buys 100 shares of the same stock with the intent of holding on to it for a year, then obviously at that point they both have the same risk. The difference comes over the course of the year. First, Person B is going to be making money from the economic value the company provides over the whole year, while the only way Person A can make money is from market fluctuation (the economic value the company provides over the course of an hour is unlikely to be significant). Person B is exposed to the risk of buying the stock, but that's counterbalanced by the profit from holding the stock for a year, while Person A just has the risk. Second, if Person A is buying a new stock every hour, then they're going to have thousands of transactions. So even though Person B assumed just as much risk as Person A for that one transaction, Person A has more total risk. No, this is not generally possible, as each security purchase is booked as a separate order => hence separate transaction. You can do this through purchasing of a fund, i.e.: purchasing one share of a ETF will get you a relative share of the ETF holdings, but the actual holdings are not up to you then. As other people have said they should register with a broker in the country they reside in that can deal in US stocks, then fill out a W8-BEN form. I have personally done this as I am from the Uk, it's not a very complicated process. I would assume that most US brokers don't allow foreign customers due to the person having to pay tax where they reside and the US brokers don't want to have to keep approximately 200 different tax codes in track. "And to answer your other questions about fees, there are a number of sites that compare brokers' fees, Google ""broker fee comparison"". I like the Motley Fool, although there are a lot of others. However, don't go just by the comparison sites, because they can be out-of-date and usually just have the basic fees. Once you find a broker that you like, go to that broker's site and get all the fees as of now. You can't sell the shares that are in your Charles Schwab account using some other broker. However, you can (possibly now, definitely eventually, see below) transfer the shares to another broker and then sell them there. But be aware that Charles Schwab might charge you a fee to transfer the shares out, which will probably be larger than the fee they'll charge you to sell the shares, unless you're selling them a few at a time. For example, I have a Charles Schwab account through my previous employer and it's $9.99 commission to sell shares, but $50 to transfer them out. Note that your fees might be different even though we're both at Charles Schwab, because employers can negotiate individual deals. There should be somewhere on the site that has a fee schedule, but if you can't find it, send them a message or call them. One final thing to be aware of, shares you get from an employer often have restrictions on sale or transfer, or negative tax consequences on sale or transfer, that shares just bought on the open market wouldn't, so make sure you investigate that before doing anything with the shares." "Your broker, Ameritrade, offers a variety of Exchange Traded Funds (ETFs) that you can buy and sell with zero commission.  An ETF is like a mutual fund, but you buy and sell shares the same way you buy and sell shares of stocks.  From your point of view, the relevance of this is that you can buy and sell as many or as few shares as you like, even down to a single share.  Note that to get the commission-free trades on the available ETFs you have to sign up for it in your account profile.  Be sure to do that before you enter any buy orders. You'll want to start by looking at the Ameritrade's list of commission-free ETFs.  Notice that they are divided into different categories:  stocks, bonds, international, and commodities.  Which categories you pick from will depend on your personal investing goals, time horizon, risk tolerance, and so on.  There are lots of questions and answers on this site that talk about asset allocation.  You should read them, as it is the most important decision you will make with your portfolio. The other thing you want to be aware of is the expense ratio for each fund.  These expenses reduce the fund's return (they are included in the calculation of the net asset value of the shares), so lower is definitely better.  Personally, I wouldn't even consider paying more than about 0.10% (commonly read ""10 basis points"" or ""10 bp"") for a broad-based domestic stock fund.  For a sectoral fund you might put up with as much as 20 bp in expenses.  Bond funds tend to be a little more expensive, so maybe allow as much as 25 bp, and likewise for international funds.  I've never invested in commodity funds, so I'll let someone else opine on appropriate expense ratios for those. Once you've decided what funds you want (and have signed up for commission-free trades), all you have to do is enter the trade orders.  The website where you manage your account has tutorials on how to do that.  After that you should be all set. Good luck with your investing!"
