How to Trade Stocks Online

If you’ve been investing for a while now—maybe through your employer’s 401(k) or an IRA—and you’re ready to take a more hands-on approach, you’re in luck. A growing number of financial firms are making online trading more convenient and affordable with easy-to-use websites and apps—often with no minimum balance required and commission-free trades.

Some online brokerages even allow investors to buy partial shares of company stocks they might not have had access to in the past because of the cost. Thanks to innovations in financial technology, or fintech, you can now buy and sell stocks and other securities from the comfort of your own couch—or while you wait in line for a latte.

But before you start buying and selling stocks from your phone, you’ll want to have at least a basic knowledge of how the market works; how online brokers execute trades; and how to develop an investing process that fits your personality, plans for the future, and bank account.

Here are some things to consider:

What Is Stock Trading?

All investors take a calculated risk with their money, with the aim of making a profit. But whether you are an investor or a trader depends on how long you typically hold on to investments. Investors are generally looking to grow their savings over the long-term for future goals, stock traders typically try to capitalize on short-term price fluctuations. That can take more time, attention, and exposure to risk than many investors would prefer to commit.

Are You an Investor?

Investors may track what’s happening with the major indexes and the securities in their portfolio, and they might do research or seek advice about the best companies in which to invest. But they’re more likely to use a buy-and-hold strategy—purchasing and keeping stocks or other securities with the idea that these investments will continue to increase in value over years or even decades.

Or Are You a Trader?

Traders keep a close eye on the market throughout the day. They pay attention to current news, tips, and research, and buy and sell stocks frequently. An active trader might buy and sell stocks several times a month, with the goal of beating the market (or getting a better return than the market average). A “day trader,” on the other hand, might buy and sell the same stock in one day, hoping to turn a quick profit and then move on to the next opportunity.

Or Are You Both?

There’s no rule that says you can’t engage in both passive and active investing. You might use your tax-deferred IRA to save for the long haul, for example, but set aside some money to try your hand at trading stocks as well.

It’s up to you how hands-on or hands-off you want to be. But knowing your investment style can help you decide if you’re really up for trading stocks yourself (instead of leaving most of the work to someone else). It also could help you choose a financial firm with the services you require.

Which Type of Broker Suits Your Style?

Investors and traders have a lot of options when it comes to choosing a broker—from long-established financial firms to newer names that offer intuitive online trading platforms and often lower costs.

If you want more help, you might be willing to pay extra for a full-service brokerage with a physical office and an actual person who takes and executes client orders. Or you might decide to limit human interaction (which can get expensive) and instead choose automated investing, leaving the heavy lifting to a robo-advisor that uses computer algorithms to build and manage an investment portfolio.

But if you truly want to get into researching and picking your own stocks, and executing trades on your own schedule, an active investing account with an online brokerage might be the right call.

Many financial websites offer up-to-date reviews of online brokerages, so that can be a good place to start researching. Some factors to consider might include:

•  The broker’s commission fees (many sites now offer free trading)

•  Account minimums (some online brokers don’t require a minimum deposit)

•  Available products (in addition to stocks, you may want to look at exchange-traded funds (ETFs), mutual funds, and/or fractional shares of stock)

•  Educational features

•  Other perks

Of course, you’ll be looking for a company with a solid reputation and good customer service. You can use the BrokerCheck database offered by the Financial Industry Regulatory Authority (FINRA) to get information on the background and experience of financial brokers, advisors and firms.

Once you choose your brokerage, you can open an account whenever you’re ready. (You don’t have to start trading right away.) You’ll probably need to provide your Social Security number and your driver’s license number or other ID. If you’re funding your brokerage account with an electronic transfer from your bank account, you’ll also want to have that information on hand. The website may ask for other information as well, to assess your goals and risk tolerance.

Learning How to Trade Stocks

Once you’ve funded your brokerage account you can start buying stocks. But be prepared—those decisions can be daunting for a newbie. While opening an account is easy, actually getting started investing may be a bit harder.

If you’re not sure where to start, you may want to look at exchange-traded funds, which offer the diversification of mutual funds but trade continuously throughout the day like stocks. ETFs are typically less expensive than either mutual funds or stocks.

Another way to get into the market at a lower cost might be to invest in fractional shares, or pieces of single shares of stocks you might otherwise find too expensive. With SoFi Invest’s fractional shares program, for example, investors can build a portfolio with big-name companies. But instead of buying whole shares, buyers specify the dollar amount they want to spend on a company’s stock. Before you invest in whole or partial shares, you may want to use an online screener to narrow your choices to stocks that meet your specific requirements and do some technical and fundamental research on potential investments. For example, are you looking for companies within a certain size range, or market capitalization (micro, small, mid, or large)? Is there a range you want to stay within when it comes to the price-to-earnings ratio (P/E)?

Most screeners offer several filters to choose from, so you can find stocks at the price you want, or in a designated industry, or within a certain level of volatility. There are several well-reviewed free screeners available that may suit your needs as a beginner, including Zacks, FINVIZ, Yahoo Finance, TD Ameritrade, and TC2000. Or you might decide to pay for a subscription service that offers more in-depth analysis.

Even if you use a screening tool, it can be useful to do your own stock research as well. There are plenty of online sites that can help you learn more about how to trade stocks and calculate stock values. And many brokerages, including SoFi, provide users with educational resources and newsletters.

In addition, the Securities and Exchange Commission (SEC) requires all public companies to file financial documents with data that could help you further assess a stock’s value. You can use the SEC’s Electronic Data Gathering, Analysis, and Retrieval system, EDGAR , to access that information.

How Do You Feel About Risk?

How much risk are you willing to take when trading stocks online?

If you’re OK with a white-knuckled, stomach-churning roller-coaster ride—and you’re willing to lose everything on an investment—you can throw caution to the wind. But if you’re hoping to make money without chronic anxiety, you’ll probably want to put some strategies in place to better manage your risk. That might include:

Knowing How Much You Can Afford to Lose

Do you have your financial bases covered (with an emergency fund, for example, and good insurance that will cover you if an unexpected health, home, or automobile expense pops up)? Are you current on your bills, and are you socking away some money for retirement? Even if you’re feeling pretty financially secure, you may want to set a clear limit on how much you’ll spend on any stocks that might expose you to more volatility and, therefore, a greater potential for loss.

Keeping Your Emotions in Check

Thanks to 24/7 access to market news, and instant reactions on social media, it can be tough to tune out distractions that can lead to knee-jerk trading moves. Greed is a tough emotion to ignore when a friend or co-worker shares a hot stock tip. And fear can easily get the better of you when you watch your favorite stock suddenly drop.

As you begin trading, you may consider a journal to document what you did and why you did it, and measure your performance against a benchmark index like the S&P 500. Reviewing those notes could help you analyze and improve how you react to changes in the market. (You’ll also want to keep good records so you can manage the tax consequences of any gains and losses in your brokerage account.)

Diversifying Your Portfolio

It’s one thing to occasionally take a small gamble on a trendy stock. It’s another to put all your money into just one stock (even a Blue Chip), or one sector, or one asset class. Keeping a balanced mix of investment types could help lower your risk—and make following your gut once in a while a little less gut-wrenching.

Again, this is where ETFs or fractional shares can come in handy. It also may be useful to work with an advisor to establish an appropriate asset allocation strategy and set up a plan that helps keep you on track as you make moves on your own.

What Type of Trade is Right for You?

When you’re ready to start using your broker’s website or app to buy and sell stocks, you’ll see there are a few different options for order types, which dictate how your trade goes through.

The type of order you use will likely vary from one situation to the next, depending on how many stocks you’re hoping to buy or sell, how liquid the stocks in question might be, or if the stock is currently under- or over-valued. And once you get more comfortable, you may want to add more strategies (such as options and futures) to your trading repertoire. So it’s a good idea to be well-versed in all the possibilities, their pros and cons, and how they might work in various scenarios.

The two most common orders are:

Market Orders

If you place a market order to buy, you’re saying you’ll purchase the stock “at market,” or at the current lowest asking price. If you place a market order to sell, you’re saying you’ll sell for whatever the highest bidding price is at that time. Because you aren’t holding out for a better price, brokers can generally fill market orders pretty quickly.

Limit Orders

If you place a limit order, you’re telling your broker in advance the price you want to get on the trade. If your broker can get the price you want (or better), they will execute the trade. But if no one is buying or selling at the price you’ve set, the trade won’t happen.

Ready to Get Started?

If you’re feeling overwhelmed, you may want to practice a bit using a free stock-trading simulator that could help you become more fluent in market terms and actions. But with your online brokerage account funded, you also could begin making small trades to get your feet wet and see how it feels.

The Takeaway

Once you begin trading stocks online, you’ll probably be able to gauge pretty quickly what works for you and what doesn’t, both financially and psychologically. Learning the basics of online trading can up your comfort level even before you get started, but executing some money-making trades will likely build your confidence. (Making some not-so-great trades could also help you finetune your process.)
