How do I invest and buy/sell stocks?  What does “use a broker” mean?
"I'm posting this because I think I can do a better job of explaining and detailing everything from start to stop. :) A ""broker"" is just someone who connect buyers and sellers - a middleman of sorts who is easy to deal with. There are many kinds of brokers; the ones you'll most commonly hear about these days are ""mortgage broker"" (for arranging home loans) and ""stockbroker"". The stockbroker helps you buy and sell stock. The stockbroker has a connection to one or more stock exchanges (e.g. Nasdaq, NYSE) and will submit your orders to them in order to fulfill it. This way Nasdaq and NYSE don't have to be in the business of managing millions of customer accounts (and submitting tax information about those accounts to the government and what-not) - they just manage relationships with brokerages, which is much easier for them. To invest in a stock, you will need to: In this day and age, most brokers that you care about will be easily accessed via the Internet, the applications will be available on the Internet, and the trading interface will be over the Internet. There may also be paper and/or telephone interfaces to the brokerage, but the Internet interface will work better. Be aware that post-IPO social media stock is risky; don't invest any money if you're not prepared for the possibility of losing every penny of it. Also, don't forget that a variety of alternative things exist that you can buy from a broker, such as an S&P 500 index fund or exchange-traded corporate bond fund; these will earn you some reward over time with significantly less risk. If you do not already have similar holdings through a retirement plan, you should consider purchasing some of these sooner or later." "Very simple. You open an account with a broker who will do the trades for you. Then you give the broker orders to buy and sell (and the money to pay for the purchases). That's it. In the old days, you would call on the phone (remember, in all the movies, ""Sell, sell!!!!""? That's how), now every decent broker has an online trading platform. If you don't want to have ""additional value"" and just trade - there are many online discount brokers (ETrade, ScotTrade, TD Ameritrade, and others) who offer pretty cheap trades and provide decent services and access to information. For more fees, you can also get advices and professional management where an investment manager will make the decisions for you (if you have several millions to invest, that is). After you open an account and login, you'll find a big green (usually) button which says ""BUY"". Stocks are traded on exchanges. For example the NYSE and the NASDAQ are the most common US exchanges (there's another one called ""pink sheets"", but its a different kind of animal), there are also stock exchanges in Europe (notably London, Frankfurt, Paris, Moscow) and Asia (notably Hong Kong, Shanghai, Tokyo). Many trading platforms (ETrade, that I use, for example) allow investing on some of those as well." Some good answers already, but let me add a TL:DR version. Brokers work like a special type of bank account where you can deposit or withdraw money. The major difference is that they also give you the ability to buy/sell investments with the money in your account which you can do by either calling them or using their website. Important: Many investments you will make through a broker(e.g. stocks) are not insured against losing value like the money in your bank account. There are 2 main types of brokers, full service and online (or discount). Basically the full service can provide you with advice in the form of recommendations on what to buy and sell and when, you call them up when you want to put an order in and the commissions are usually higher. Whilst an online broker usually doesn't provide advice (unless you ask for it at a specified fee), you place your orders online through the brokers website or trading platform and the commissions are usually much lower. The best thing to do when starting off is to go to your country's stock exchange, for example, The ASX in Sydney Australia, and they should have a list of available brokers. Some of the online brokers may have a practice or simulation account you can practice on, and they usually provide good educational material to help you get started. If you went with an online broker and wanted to buy Facebook on the secondary market (that is on the stock exchange after the IPO closes), you would log onto your brokers website or platform and go to the orders section. You would place a new order to buy say 100 Facebook shares at a certain price. You can use a market order, meaning the order will be immediately executed at the current market price and you will own the shares, or a limit price order where you select a price below the current market price and wait for the price to come down and hit your limit price before your order is executed and you get your shares. There are other types of orders available with different brokers which you will learn about when you log onto their website. You also need to be careful that you have the funds available to pay for the share at settlement, which is 3 business days after your order was executed. Some brokers may require you to have the funds deposited into an account which is linked to your trading account with them. To sell your shares you do the same thing, except this time you choose a sell order instead of a buy order. It becomes quite simple once you have done it a couple of times. The best thing is to do some research and get started. Good Luck.
"Traditional brokers There are tons of players in this market, especially in USA. You have traditional brokers, brokers tied to your bank and a bunch of startups. The easiest is probably a broker tied to your bank, because you probably don't have to wait to fund your brokerage account and can start trading immediately. Often the older/traditional brokers don't have very intuitive interfaces, it's the startups who do a better job at this. But honestly it doesn't really matter, because you can use reporting services that are different from the services you use to execute your trades. Meaning that you only use the interface of your broker to execute trades (buy or sell), and use third party services to monitor your holdings. Monitoring services: Google Finance, Yahoo Finance, Sigfig, Morningstar,... are services allowing you to monitor your holdings. But you can't execute trades with them. Start-ups: Then there are a bunch of startups that offer investment services besides the traditional brokers. Start-up > Robinhood The most ambitious one is Robinhood, which offers the same service as a traditional broker, but completely free (most of the traditional brokers charge a flat fee and/or percentage when buying/selling hodlings) and with an intuitive interface. They're mobile first, but announced they will be launching their service on the web soon. Start-up > Acorns Another popular, mobile-first start-up is Acorns. They offer a lazy-investing service which rounds your everyday purchases and uses the change to invest. It's great when investing is not on your mind, but you still want to invest without realizing it. Start-ups > Robo-advisors Robo-advisors auto-invest your money across a bunch of funds picked based on your risk profile. Because the robo-advisers are fairly new, they often have the most intuitive interfaces. These robo-advisors often don't allow you to pick individual holdings, so these services are best when you want to passively invest. Meaning you don't want to look at it very often, and let them do the investing for you. There are tons of robo-advisor start-ups: Betterment, Wealthfront, Personal Capital, Sigfig, FutureAdvisor,... Also bigger parties jumped on this trend with their offerings: Schwab Intelligent Portfolios, Ally Managed Portfolio, Vanguard Personal Advisor, etc. Summary: It's fun to pick individual stocks, but if you start out it can be overwhelming. Robinhood is probably the best start, they have reduced functionality, but gets you going with an attractive interface. But soon you'll realize it's extremely hard to beat the market. Meaning that hand-picking stocks statistically gives you a worse return than just buying into the general stock market (like S&P500). So you can decide to just buy one fund with a traditional broker that covers the general stock market. Or you can decide to try out one of the many robo-advisors. They haven't been around that long, so it's hard to tell how effective these are and whether they beat the market. If you're young, and you believe in start-ups (who often try to challenge the traditional players), try out one of the robo-advisors. If you want to play a bit and are addicted to your smartphone, try out Robinhood. If you are addicted to your phone, but don't want to check up on your investments all the time, go for Acorns. Of course you can combine all these. Lastly, there are tons of cryptocurrencies which might give you a large return. Tons of startups offer intuitive interfaces to trade cryptocurrencies like Coinbase, Gemini, Kraken. But beware, there is a lot of risk involved in trading cryptocurrencies, it's completely unregulated etc. But definitely check them out. Oh, and you can also invest by giving out loans through LendingClub, Prosper etc. Who can you trust? Above gives you an overview of your options intermingled with some reasoning. But regarding your question ""who can I trust"" in terms of advice, it's up to yourself. Most traditional broker services don't give you any advice at all, you're on your own. Robo-advisors don't give you advice either, but let their proprietary algorithm do the job. Are these reliable? Nobody can tell, they haven't been around long enough, and they need to go through a bear market (a crash) to see how they respond during rough times. Some robo-advisors offer you personal consultancy (I believe Sigfig and PersonalCapital) does this (limited to a few hours per year). But obviously they'll try to promote their robo-advisor services." "I think you've got basics, but you may have the order / emphasis a bit wrong. I've changed the order of the things you've learned in to what I think is the most important to understand: Owning a stock is like owning a tiny chunk of the business Owning stock is owning a tiny chunk of the business, it's not just ""like"" it. The ""tiny chunks"" are called shares, because that is literally what they are, a share of the business. Sometimes shares are also called stocks. The words stock and share are mostly interchangeable, but a single stock normally means your holding of many shares in a business, so if you have 100 shares in 1 company, that's a stock in that company, if you then buy 100 shares in another company, you now own 2 stocks. An investor seeks to buy stocks at a low price, and sell when the price is high. Not necessarily. An investor will buy shares in a company that they believe will make them a profit. In general, a company will make a profit and distribute some or all of it to shareholders in the form of dividends. They will also keep back a portion of the profit to invest in growing the company. If the company does grow, it will grow in value and your shares will get more valuable. Price (of a stock) is affected by supply/demand, volume, and possibly company profits The price of a share that you see on a stock ticker is the price that people on the market have exchanged the share for recently, not the price you or I can buy a share for, although usually if people on the market are buying and selling at that price, someone will buy or sell from you at a similar sort of price. In theory, the price will be the companies total value, if you were to own the whole thing (it's market capitalisation) divided by the total number of shares that exist in that company. The problem is that it's very difficult to work out the total value of a company. You can start by counting the different things that it owns (including things like intellectual property and the knowledge and experience of people who work there), subtract all the money it owes in loans etc., and then make an allowance for how much profit you expect the company to make in the future. The problem is that these numbers are all going to be estimates, and different peoples estimates will disagree. Some people don't bother to estimate at all. The market makers will just follow supply and demand. They will hold a few shares in each of many companies that they are interested in. They will advertise a lower price that they are willing to buy at and a higher price that they will sell at all the time. When they hold a lot of a share, they will price it lower so that people buy it from them. When they start to run out, they will price it higher. You will never need to spend more than the market makers price to buy a share, or get less than the market makers price when you come to sell it (unless you want to buy or sell more shares than they are willing to). This is why stock price depends on supply and demand. The other category of people who don't care about the companies they are trading are the high speed traders. They just look at information like the past price, the volume (total amount of shares being exchanged on the market) and many other statistics both from the market and elsewhere and look for patterns. You cannot compete with these people - they do things like physically locate their servers nearer to the stock exchanges buildings to get a few milliseconds time advantage over their competitors to buy shares quicker than them." High frequency trades are intra day. The would buy a stock for 100 and sell for 100.10 multiple times. So If you start with 100 in your broker account, you buy something [it takes 2-3 days to settle], you sell for 100.10 [it takes 2-3 days to settle]. You again buy something for 100. It is the net value of both buys and sells that you need to look at. Trading on Margin Accounts. Most brokers offer Margin Accounts. The exact leverage ratios varies. What this means is that if you start with 10 [or 15 or 25] in your broker you can buy stock of 100. Of course legally you wont own the stock unless you pay the broker balance, etc. I was wondering what relations are between brokerage companies and exchanges? Are brokers representing investors to trade on exchanges? Yes...but a broker may also buy and sell stocks for his own account. This is called broker-delaer firm. For individual investors, what are some cons and pros of trading on the exchanges directly versus indirectly via brokers? Doesn't the former save the investors any costs/expenses paid to the brokers? Yes, but to trade directly on an exchange, you need to register with them. That costs money and only a limited number of people can register I believe. Note that some (or all?) exchanges have their websites where I think trading can be done electronically, such as NASDAQ and BATS? Can almost all stocks be found and traded on almost every exchange? In other words, is it possible that a popular stock can only be found and traded on one exchange, but not found on the other exchange? If needed to be more specific, I am particularly interested in the U.S. case,and for example, Apple's stock. Yes, it is very much possible with smaller companies. Big companies are usually on multiple exchanges. What are your advices for choosing exchange and choosing brokerage companies? What exchanges and brokerage companies do you recommend? For brokerage companies, a beginner can go with discount broker. For sophisticated investors can opt for full service brokers. Usually your bank will have a brokerage firm. For exchanges, it depends...if you are in US, you should send to the US exchanges. IF you wish to send to other exchanges in other countries, you should check with the broker about that. The earlier answers answered the question on how a more practical trader can lose money. Here I'd like to mention some obtuse ways  Using debt to buy stocks. If one is borrowing at a higher rate than they are getting back, from an economics prospective their stocks are losing money even if the value of those stocks are going up. Using debt to buy stocks. I'll simplify the nightmare situation. I know someone who has Y dollars of cash. Their broker will loan them X. With their X+Y money, they purchase some equities through the broker. The agreement of the loan is that if the value of those equities drops below a certain percentage of the outstanding debt (ex 150%), the broker will automatically and without notification, sell some equities indiscriminately to reduce the outstanding debt. Being in high-interest debt but buying stocks. There are millions of people who are paying 15+% interest rates on consumer debt while investing and getting 5% returns or less on average. Similar to an earlier point, from an economics prospective the choice to buy equities is a profit losing choice. Traders trade for a living, stockbrokers tell people to get involved in trades for a living. To be employed as a trader, you need a proven track record of being able to consistently make money. To be employed as a stockbroker, you need to get licensed but you don't need to prove you can consistently make money. It's actually quite simple. You're actually confusing two concept. Which are taking a short position and short selling itself. Basically when taking a short position is by believing that the stock is going to drop and you sell it. You can or not buy it back later depending on the believe it grows again or not. So basically you didn't make any profit with the drop in the price's value but you didn't lose money either.  Ok but what if you believe the market or specific company is going to drop and you want to profit on it while it's dropping. You can't do this by buying stock because you would be going long right? So back to the basics. To obtain any type of profit I need to buy low and sell high, right? This is natural for use in long positions. Well, now knowing that you can sell high at the current moment and buy low in the future what do you do? You can't sell what you don't have. So acquire it. Ask someone to lend it to you for some time and sell it. So selling high, check.  Now buying low? You promised the person you would return him his stock, as it's intangible he won't even notice it's a different unit, so you buy low and return the lender his stock. Thus you bought low and sold high, meaning having a profit. So technically short selling is a type of short position. If you have multiple portfolios and lend yourself (i.e. maintaining a long-term long position while making some money with a short term short-term strategy) you're actually short selling with your own stock. This happens often in hedge funds where multiple strategies are used and to optimise the transaction costs and borrowing fees, they have algorithms that clear (match) long and short coming in from different traders, algorithms, etc. Keep in mind that you while have a opportunities risk associated.  So basically, yes, you need to always 'borrow' a product to be able to short sell it. What can happen is that you lend yourself but this only makes sense if: "Largely, because stock markets are efficient markets, at least mostly if not entirely; while the efficient market hypothesis is not necessarily 100% correct, for the majority of traders it's unlikely that you could (on the long term) find significant market inefficiencies with the tools available to an individual of normal wealth (say, < $500k). That's what frequent trading intends to do: find market inefficiencies.  If the market is efficient, then a stock is priced exactly at what it should be worth, based on risk and future returns.  If it is inefficient, then you can make more money trading on that inefficiency versus simply holding it long.  But in stating that a stock is inefficient, you are stating that you know something the rest of the market doesn't - or some condition is different for you than the other million or so people in the market.  That's including a lot of folks who do this for a living, and have very expensive modelling software (and hardware to run it on).  I like to think that I'm smarter than the far majority of people, but I'm probably not the smartest guy in the room, and I certainly don't have that kind of equipment - especially with high frequency trading nowadays. As such, it's certainly possible to make a bit of money as a trader versus as a long-term investor, but on the whole it's similar to playing poker for a living.  If you're smarter than most of the people in the room, you might be able to make a bit of money, but the overhead - in the case of poker, the money the house charges for the game, in the case of stocks, the exchange fees and broker commissions - means that it's a losing game for the group as a whole, and not very many people can actually make money.  Add to that the computer-based trading - so imagine a poker game where four of the eight players are computer models that are really good (and actively maintained by very smart traders) and you can see where it gets to be very difficult to trade at a profit (versus long term investments, which take advantage of the growth in value in the company). Finally, the risk because of leverage and option trading (which is necessary to really take advantage of inefficiencies) makes it not only hard to make a profit, but easy to lose everything.  Again to the poker analogy, the guys I've known playing poker for a living do it by playing 10-20 games at once - because one game isn't efficient enough, you wouldn't make enough money.  In poker, you can do that fairly safely, especially in limit games; but in the market, if you're leveraging your money you risk losing a lot.  Every action you take to make it ""safer"" removes some of your profit." Im an actor preparing for a role. I play a trader in the UK during the late 80s. I have a very basic understanding of the stock market and am unsure what some of the dialogue is referring to. For example: “bid 28 at the figure” “sell at 3” “5 march at 28” “9 for 5” “bid 4 at 6” “closing out now at 4”. What do these numbers mean exactly. It doesn’t help that im Australian and this is a UK production, or that im an idiot "Hmm... Well there are several ways to do that: Go to any bank (or at the very least major ones). They can assist you with buying and/or selling stocks/shares of any company on the financial market. They keep your shares safe at the bank and take care of them. The downside is that they will calculate fees for every single thing they do with your money or shares or whatever. Go to any Financial broker/trader that deals with the stock market. Open an account and tell them to buy shares from company ""X"" and keep them. Meaning they won't trade with them if this is what you want. Do the same as point 2, but on your own. Find a suitable broker with decent transaction fees, open an account, find the company's stock code and purchase the stocks via the platform the broker uses." "Your inference in #1 is incorrect.  The million dollars he has contributed is going to be part of the assets of the fund.  This is common practice and is a way for the founder to express confidence that the fund will make money.  He wants you to come up with a model that he can then use to trade those assets.  Presumably he will give you some money if he uses your model and it works. Regarding #2, there are lots of ways of getting data.  Sometimes you can buy it directly from the exchange.  You can also buy from vendors like tickdata.com.  There are lots of such vendors.  Since he makes a big deal about saying it's expensive, I'm assuming he is talking about data at relatively high frequency (not daily, which would be cheap).  Stock data is still not bad.  Complete US data would be a few thousand dollars (maybe 20K at the most).  For someone sitting at home with no capital, that's a lot of money, but for a hedge fund it's nothing. As an institutional investor, your broker will give you a data feed that will provide all prices in real time (but not historically).  If he's been in operation a while, he could have just saved the prices as they came out of the pipe.  I don't think that's the case here, though, based on how young he is and how little money is involved. In short, he paid for some data and has ""encrypted"" it in such a way that he can legally share it for free.  Supposedly his method preserves the structure so that you could write a trading model based on the encrypted data and it would work on real data.  Once you have a good trading model, you sell it to him and he will use it to trade his million dollars and whatever other money he is able to gather." You must understand that: So, if you -- the prospective buyer -- are in Waukegan, do you take the train all the way to New York City just to buy 100 shares of stock?  No.  That would be absurdly expensive.  So, you hire an agent in NYC who will broker a deal for you in the exchange. Fast forward 100 years, to the time when instant communications is available.  Why do we now still need brokerages, when the Exchanges could set up web sites and let you do the trading? The answer is that the Exchanges don't want to have to develop the accounting systems to manage the transactions of hundreds of thousands of small traders, when existing brokerage firms already have those computerized processes in place and are opening their own web sites. Thus, in 2017 we have brokerage firms because of history. A lot of people here talk about shorting stocks, buying options, and messing around with leveraged ETFs. While these are excellent tools, that offer novel opportunities for the sophisticated investor, Don't mess around with these until you have been in the game for a few years. Even if you can make money consistently right out of the gate, don't do it. Why? Making money isn't your challenge, NOT LOSING money is your challenge. It's hard to measure the scope of the risk you are assuming with these strategies, much less manage it when things head south. So even if you've gotten lucky enough to have figured  out how to make money, you surely haven't learned out how to hold on to it. I am certain that every beginner still hasn't figured out how to comprehend risk and manage losing positions. It's one of those things you only figure out after dealing with it. Stocks (with little to no margin) are a great place to learn how to lose because your risk of losing everything is drastically lower than with the aforementioned tools of the sophisticated investor. Despite what others may say you can make out really well just trading stocks.  That being said, one of my favorite beginner strategies is buying stocks that dip for reasons that don't fundamentally affect the company's ability to make money in the mid term (2 quarters).  Wallstreet loves these plays because it shakes out amateur investors (release bad news, push the stock down shorting it or selling your position, amateurs sell, which you buy at a discount to the 'fair price'.) A good example is Netflix back in 2007. There was a lawsuit because netflix was throttling movie deliveries to high traffic consumers. The stock dropped a good chunk overnight.  A more recent example is petrobras after their huge bond sale and subsequent corruption scandal. A lot of people questioned Petrobras' long-term ability to maintain sufficient liquidity to pay back the loans, but the cashflow and long term projections are more than solid. A year later the stock was pushed further down because a lot of amateur Brazilians invest in Petrobras and they sold while the stock was artificially depressed due to a string of corruption scandals and poor, though temporary, economic conditions. One of my favorite plays back in 2008-2011 was First Solar on the run-up to earnings calls. Analysts would always come out of these meetings downgrading the stock and the forums were full of pikers and pumpers claiming heavy put positions. The stock would go down considerably, but would always pop around earnings. I've made huge returns on this move. Those were the good ole days. Start off just googling financial news and blogs and look for lawsuits and/or scandals. Manufacturing defects or recalls. Starting looking for companies that react predictably to certain events. Plot those events on your chart. If you don't know how to back-test events, learn it.  Google Finance had a tool for that back in the day that was rudimentary but helpful for those starting out. Eventually though, moreso than learning any particular strategy, you should learn these three skills: 1) Tooling: to gather, manipulate, and visualize data on your own.  These days automated trading also seems to be ever more important, even for the small fish. 2) Analytical Thinking learn to spot patterns of the three types:  event based (lawsuits, arbitrage, earnings etc), technical (emas, price action, sup/res), or business-oriented (accounting, strategy, marketing). Don't just listen to what someone else says you should do at any particular moment, critical thinking is essential. 3) Emotions and Attitude: learn how to comprehend risk and manage your trigger finger. Your emotions are like a blade that you must sharpen every day if you want to stay in the game. Disclaimer: I stopped using this strategy in 2011, and moved to a pure technical trading regime. I've been out totally out of the game since 2015. Step 1: Get a part-time job in sales.  Perhaps selling appliances at Sears. Step 2: If you are great at that, then look into becoming a stock broker/investment adviser in Boise ... which is a sales job.   Step 3: If you are great at that, then you might be able to become a portfolio manager, perhaps a hedge fund manager for the clients you collected as a stock broker/ investment consultant.   That seems to be the steps I have seen from reading the bios of a number of professional investors.   The other method seems to be an MBA from a top 10 business school. "Ryan's suggestion to index for your main strategy is dead on. Your risk is highest with one given stock, and decreases as you diversify. Yet, picking the stocks one at a time is an effort, when done right, it's time consuming. For what one can say about Jim ""mad money"" Cramer, his advice to spend an hour a month studying each stock you own, is pretty decent advice.  Penny stocks are sub one dollar priced, typically small companies which in theory can grow to be large companies, but the available information tends to be tougher to get hold of.  Options are a discussion for a different thread, I discussed the covered call strategy elsewhere and show that options are not necessarily high risk, it depends how they are used."
