In the stock market, for every buyer, there is a seller. When you buy 100 shares of stock, someone is selling 100 shares to you. Similarly, when you go to sell your shares of stock, someone has to buy them. If there are more buyers than sellers (demand), then the stock price will go up. Conversely, if there are more sellers than buyers (too much supply), the price will fall.
How much money do I need to get started investing? Not much. Note that many of the brokers above have no account minimums for both taxable brokerage accounts and IRAs. Once you open an account, all it takes to get started is enough money to cover the cost of a single share of a stock and the trading commission. (See “How to Buy Stocks” for step-by-step instructions on placing that first trade.)
Shouldn’t I just choose the cheapest broker? Trading costs definitely matter to active and high-volume traders. If you’re a high-volume trader — buying bundles of 100 to 500 shares at a time, for example — Interactive Brokers and TradeStation are cost-effective options. Ally Invest offers $3.95 trades ($1 off full price) for investors who place more than 30 trades a quarter. Commissions are less of a factor for buy-and-hold investors, a strategy we recommend for the majority of people. Most online brokers charge from $5 to $7 per trade. But other factors — access to a range of investments or training tools — may be more valuable than saving a few bucks when you purchase shares.
Where should I invest my money?
Our experts suggest you begin by looking at your own life. “Buy what you know, where you are. If you can, identify good companies locally,” says Randy Cameron, a portfolio manager and investment advisor with 35 years of experience. “Look for companies you and your friends are talking about, ones with plans to go national.” As for how much time and money you need, “start with what you have,” he says. There is literally no minimum to get started, and starting with just one share is better than putting things off.
How do I determine if a brokerage firm is right for me before I open an account? Some key criteria to consider when evaluating any investment company are how much money you have, what type of assets you intend to buy, your trading style and technical needs, how frequently you plan to transact and how much service you need. Our post about how to choose the best broker for you can help you sort through the features brokerage firms offer and rank your priorities.
In most cases, your broker will charge a commission every time that you trade stock, either through buying or selling. Trading fees range from the low end of $2 per trade but can be as high as $10 for some discount brokers. Some brokers charge no trade commissions at all, but they make up for it in other ways. There are no charitable organizations running brokerage services.
TD Ameritrade has been a powerful player in the online stock trading ecosystem for years. The flipside to such robust platforms? Cost. Even though TD Ameritrade lowered its fees in 2017 from $9.99 to $6.95, pretty much every other major discount broker slashed its prices, too. TD Ameritrade remains one of the more expensive options out there, even with more than 100 commission-free ETFs. Though its pricing structure is more expensive than those of some of the other discount brokers, there are many traders who think it's a best-in-class trading platform.
How can I build a diversified portfolio for little money? One easy way is to invest in exchange-traded funds. ETFs are essentially bite-sized mutual funds that are bought and sold just like individual stocks on a stock market exchange. Like mutual funds, each ETF contains a basket of stocks (sometimes hundreds) that adhere to particular criteria (e.g., shares of companies that are part of a stock market index like the S&P 500). Unlike mutual funds, which can have high investment minimums, investors can purchase as little as one share of an ETF at a time.
